Pine Nuts Left a Bitter Taste in my Mouth

Are you suffering from a bitter taste in the back of your mouth every time you eat or drink?  Has it lasted for more than a day?  Are you starting to worry that perhaps there’s something terribly wrong with you?  Don’t worry, it’s probably not a brain tumor.  Perhaps pine nuts are the culprit!

So I woke up yesterday morning with a headache.  Nothing terrible, it happens.  Instead of taking ibuprofen on an empty stomach, I grabbed a Ritz cracker out of the pantry to eat before I took the pill.  I ate the cracker and noticed that it tasted terrible.  Now, it was from a sealed package, but those crackers have been sitting in there for months so I figured they were just stale.  Whatever.  I took my pill, then sat down with a cup of coffee.  The coffee tasted bad, too.  I just had this weird, bitter taste in the back of my mouth.  But, I figured maybe there was just something wrong with my throat.  Perhaps I was coming down with something, there are lots of nasty bugs floating around right now and I had woken up with a headache after all.  Later that morning I decided to try some of the chili (breakfast of champions!) that my friend Amanda had dropped off on her way to work.  The chili had the same bitter aftertaste as everything else I had consumed up to that point.  Now I knew there was a problem.  Amanda doesn’t make bad food!  Sure enough, every other thing I tried to eat yesterday tasted horrible, and it seemed to get worse as the day progressed.  There was definitely something going on with my tastebuds.  So I did what any red-blooded, internet-obsessed hypochondriac American would have done.  I googled my symptoms.

Well, it took all of about 2 seconds to find several accounts of people suffering the exact symptoms, and scanning the page, the words ‘pine nuts’ jumped out at me.  I had been eating a TON of pine nuts for the last few days.  So I refined my google search to include the phrases “pine nuts” and “bitter taste.”  With 30 seconds of my original search, I had the answer to the bitter taste mystery!

Apparently, if you are one of the lucky people who runs into a bad pine nut or two, you could develop the taste disturbance that I am experiencing right now.  There’s a scientific article about it and it’s even mentioned in the Wikipedia entry on Pine Nuts:

The eating of pine nuts can cause serious taste disturbances, developing 1-3 days after consumption and lasting for days or weeks. A bitter, metallic taste is described. In general, a minority of pine nuts on the market present this problem. Though very unpleasant, there does not seem to be a real health concern. — Wikipedia

Nobody seems to be able to explain exactly why it happens.  But after reading several accounts, I am satisfied that pine nuts are the culprit in my case.  It seems that this bitter taste can last anywhere from a couple of days to over a week.  Ugh, lucky me!

Now I am not writing this to start a pine nut panic!  Several blog posts are blaming this issue on pine nuts from China, but my pine nuts weren’t from China.  I bought them at Trader Joe’s and the package states that they came from one of three places: Korea, Russia, or Vietnam.  I don’t believe that this a case of China selling poisoned pine nuts to the United States, although the Chinese variety of pine nuts may be more susceptible to the problem.  I think that there are some bad nuts out there that appear to be coming from several undetermined sources and unfortunately at least one of them ended up in my mouth. But since it seems that this is happening more with Chinese pine nuts than with Italian pine nuts, I think I’ll stick to the Italian ones from here on out!

So, will this keep me from eating pine nuts in the future?  Hell no!  I love them too much.  I will, however, be more careful about where I purchase them.  I will spend more money and make sure they are fresh and that I know exactly where they are coming from.  Sorry, Trader Joe’s!

Here are some general guidelines I suggest you follow when purchasing/storing pine nuts:

– Buy the more expensive Italian pine nuts and make sure it’s from a store with a high turnover.
– Pine nuts turn rancid very quickly, so buy in small quantities and store them well-wrapped in the refrigerator for short periods of time, or in the freezer if you need to store them for an extended period of time.  Just make sure you keep those suckers cold!

Now I know that google is no substitute for a doctor, but after my research I’m satisfied that my taste disturbance is indeed caused by pine nuts.  I’m not sick, I have no symptoms other than the bitterness in my mouth (I’m positive that the headache I mentioned at the beginning of my story had more to do with the wine consumed the night before than with pine nut poisoning).  The bitter taste is annoying, but I don’t feel that my health is in danger.  I eat a lot of pine nuts and have been doing so for years.  This is the first time I’ve ever had a problem and I’m confident that if I’m careful with my pine nut purchases in the future, it won’t happen again.

So, has this happened to any of you?  If so, where did your pine nuts come from?

    Of course when I was reading about this on Twitter, I had to have a few nibbles of my own from-China pine nuts (Costco brand) just to see if they were okay. So far so good.

    Good tip about keeping them cold! I store mine in the freezer, in a sealable bag that’s inside a plastic snap-top container.

    Hope your tastebuds will get back to normal sooner rather than later!

    I go through these “everything is bitter” periods … it’s not pine nuts for me, at least not at the moment. Sometimes I think it might be cheese, like some of the blue cheeses or smoked foods.The good news is that it goes away and the bitterness, now that I know that it’s not the food I’m eating, but me, I can kind of get past it.

    This happened to me a few months ago and I googled “metallic taste” but got no where. It went away after a few days and I forgot all about it until now. Pine nuts could definitely be the culprit-they make brussel sprouts the BEST. Cheers.

    In the course of my professional recipe development over the years, I’ve found that some mouth washes really affect the flavor of food, even 48 hours later. Metallic overtones come through with many, but not all foods. So I avoid mouth wash when I’m getting serious in the kitchen.

    Thanks for the heads up on this. Why is it that this always goes back to a problem from China or Asia? I emailed Trader Joe’s and let them know they have a problem and that they might want to reconsider their supplier of pine nuts. In the meantime, I’ll search for Italian ones, or some from New Mexico.

    I eat pine nuts all the time and this has never happened to me, but I’m only eating organic ones that I buy in bulk. My guess is that it’s not the pine nuts themselves but something that they have been treated with.

    I have the same problem with pine nuts. It happens to me almost every time so now I just avoid them. I always figured that it was my palate and nothing wrong with the pine nuts. Usually I am dining with others who have them and never complain about the after taste. But I am one of those people who doesn’t like raw spinach because it leaves an after taste in my mouth.

    I grew up in New Mexico and we picked our own pine nuts (pinon), I don’t recall ever having this problem. I do remember during the picking season there were nut shells everywhere, even in the ashtray in the State Capital elevator!

    I’ve never heard of this problem with pine nuts before. I do know, however, that a strong metallic taste in your mouth is one of the first signs of pregnancy! Maybe pine nuts could be substituted by walnuts, blanched almonds, or hazelnuts to avoid the problem.

    What a coincidence. This happened for the first time last week. I only got the bitter taste once, but my husband and sister-in-law had it for days. My mother-in-law had the pine nuts, but I don’t know where she got them or how she stored them. It is the weirdest thing!

    This is so fortuitous! I’ve had this experience twice in the past month. The first time it lasted for 3 days and the second only for one. I don’t remember if I ate pine nuts but it’s highly possible. I’ve been making a lot of pesto lately. At first I described it as a bitter taste. Then later realized that it was more like…perfume. Chemical-like. So distracting! Maybe it was the pine nuts? I don’t plan to cut back anytime soon so maybe I’ll find out sooner than later. Thanks for the info!

    yes, happening to me currently…the only common link in all of this has been the recent consumption of pine nuts…!! (these had not been stored in a cool place and possibly a week or so old…) can not get rid of the bitter taste so far…..would be great to hear of a remedy for the problem….. so again, YES, it appears to be the pine nuts…. wow, never would have believed it…!!

    How odd and scary. Never happened to me, but then, I don’t eat pine nuts that often. Very rarely you can find them natively grown from the Southwest. I have a New Mexican brand of coffee flavored with pinyon. Not bad.

    Not having heard anything bad about pine nuts in the past, I started eating pine nuts this week and now have a horribly bitter taste in my mouth when I eat anything. I bought mine from Trader Joes. I’m going to try and return the rest of the bag. Thanks for the information regarding pine nuts and for these comments. I feel better already.

    Well it’s day six now and the bitterness is finally going away. I can still taste it, but it’s definitely diminished so there is some light at the end of the tunnel! Carmen: I tried e-mailing Trader Joe’s a few days ago, but got no response.

    Good god, I just googled this and now I’m so freaked out. I am having the same experience today, except I went so far as to call General Mills when the brand-new box of Honey Nut Cheerios I opened for breakfast was bitter. I’ve never called a company before, but seriously, it was horrible. Of course, everything I’ve eaten all day has been equally horrible so now, in addition to the bitter taste in my mouth, I have guilt.

    Oh, and sure enough, I ate a fistful of pine nuts yesterday.

    How odd is this? I have been having this bitter taste in my mouth for two days and never thought it could be the pine nuts I had the other day. I have had pine nuts before and never experience this bitter taste. So glad I googled this and learned there is nothing really seriously wrong with me. I though my sinues or the back of my throat had a problem, glad to hear I am not alone. My husband ate pine nuts from the same batch and does not experience any bitterness.

    I just googled this site and can’t believe this. Two days ago I ate a small bag of pine nuts from a bulk that we bought at Whole Foods. Then woke up this morning and after my yogart which I could hardly finish because of this awful taste, realized something was wrong. Has gotten worse during the day with every bite I take. Are there any remedies to help it go away fast???

    Wow, I have never heard of this happening, it’s very interesting that pine nuts are possibly behind this aftertaste that people experience. I eat pine nuts from time to time but my mother-in-law devours them! 🙂 I am going to have to ask her if she has ever experienced these symptoms!

    Thanks for the information, great blog!

    I had a bitter taste in the back of my throat after anything I ate or drank all weekend. I called the dentist first thing this morning in case it was an infection from a possible cracked filling or something like that – he took x-rays and poked around and nothing. I came home and googled (ya gotta love google ! ) “bitter taste in mouth after eating” and was surprised to find several hits with pine nuts listed as the cause. And you guessed it – I had pine nuts in my appetizer Thursday night when I went out to dinner with my husband. I have had pine nuts before but usually buy organic and keep them in my fridge – this is the first time I ever remember having this happen. I am into day 4. I hope it goes away soon – water and beer are the only things that seem okay, bread, crackers, tortilla’s that sort of thing seem the worst. I was able to tolerate an apple today – so maybe I am on the mend.

    Well, I found your site the same way you found out about the pine nuts – googling my symptoms! All day yesterday, everything I ate tasted bitter. I was getting seriously annoyed. Sounds like pine nuts are the culprit in my case too! I had a salad with pine nuts a couple of days ago. Ugh. I hope this goes away soon!

    Thanks for posting this! I had this happen to me yesterday. I kept thinking that the food I was eating was a little off, until I realized it had to be me. Then I started freaking out, did a search and found your posting, and realized I _had_ eaten some pine nuts just a few hours before it started happening.

    I had even packed some more nuts to eat today — I guess I’m skipping the pine nuts among them.

    I have been baffled and so concerned as to why this has happened to me twice in the past month. So, like most of you, I googled my symptoms, a terrible taste in the back of my throat that wont go away. My search led me here, and turns out. Both times this has happened was after making pesto, a key ingredient being pine nuts, and….I bought them at Trader Joes both times….

    I am so glad I finally did a Google search. All I typed in was “all food tastes bitter” because that’s exactly what I had been going through. It would go on for days at a time starting a couple of months ago. I thought that it was the rubber case on my Blackberry phone so I washed it and made sure I washed my hands before I ate ANYTHING. Eventually, it went away but it returns once in a while. Low and behold, I stumble upon your article and of course, I get the same pine nuts. From Trader Joe’s in Alameda, Calif. I love pine nuts but I can’t stand this bitter taste crap. I might not have the fortitude to keep eating them if this continues. Oddly enough, I make salads for my wife with the same nuts and she’s never experienced that problem. Oh well. Thanks so much for sharing!

    I finally got a response from Trader Joe’s regarding their pine nuts and here’s what they had to say (pretty much what I’ve already discovered on my own):


    Thank you for your feedback. We would like to extend our apologies for
    this unpleasant experience. We are aware this has been occurring more
    frequently with the batch of Pine Nuts we currently have available.
    This is an all natural occurrence and poses absolutely no health risk,
    but may linger for a day or so, or possible a couple weeks.

    This is not just an occurrence with Trader Joe’s brand or source, and
    not everyone reacts to the natural pine oils like this. Unfortunately,
    there are no quick remedies or preventive measure we can take to ensure
    it doesn’t happen again, and there also isn’t a way to determine if this
    may occur with future batches.

    I also wanted to make sure you are aware of our “Product Guarantee.” If
    you are dissatisfied with any product purchased in our stores, you can
    take it back for an exchange or full refund. We stand behind our motto,
    “We tried it! We liked it! If you don’t, bring it back for a full
    refund, no questions asked.”

  37. Nancy too! Except I had a bout of diarrhea after ingesting my salad with pine nuts and had an ache in my stomache for nearly a week. I called the FDA. When they found I didn’t have the original package or contents left he wouldnt take a report. I argued rather strongly about what would it take to get him to take a report…someone really damaged or dead?? 3 days later he called back and left a message..he had checked their data base and indeed pinenuts were causing a problem and I was ok to eat them anyways. Maybe for him..not for me!!
    I also called the Poison Center but no one called me back. It was pretty awful..I emailed all my friends and have posted in these blogsand emails Oprah and ABC…at least I felt like I did something,

    I experienced that many times, tasting bitter-like foods and it makes me sick that causes me nausea, headache and very awful taste. I tried a syrup medicine which is more in lactobacillus, but its really bitter like your pine nuts and really awful.Thanks for sharing about this experience you had.

    I bought a salad from Pret-a-Manger last week with pine nuts and I’m still suffering from the bitterness of this. It’s not their fault, they make excellent food and to be honest, I can’t even say it definitely was their pine nuts – but I didn’t eat any from anywhere else. All I know is that they wouldn’t skimp on cheap ingredients… I’ve been eating pine nuts for about a year now and never experienced this before. It’s almost a week later and the taste is starting to go away but its definitely still there. I want to get stoned and forget about it… but it even makes my dope taste wrong…

    Wow! This is great finding the answer to the bitter taste I’ve had in my mouth after everything I eat. I made a pesto dip for the first time for my daughter’s piano recital on the 17th of May. I ate the leftovers for two days in a row and had put the extra pine nuts in a bowl on the counter to munch on (we keep different nuts out for us all to have something healthy to munch). Our family has never had pine nuts before – my girls never tried them, but my son and I would grab a few here and there. I have been trying to diet, so the way everything tasted bad has really been good – but I got to wondering if it was some of the new vitamins or suppliments I was taking. That’s why I Googled “metalic bitter taste”. When I saw that others have had this happen because of pine nuts, I asked my son if he has had bad after tastes too, and he said even the cupcake I said he could have after lunch today tasted aweful!! I got mine in bulk at Sprouts – and since the temps have been hitting records in Arizona it’s no wonder the pine nuts are no good. I wouldn’t know what they should taste like, but right from the start they left an aftertaste. The pesto dip covered that taste, I think, as it was also layered with minced, dried tomatoes and cream cheese. I guess it’s a good diet trick – but even water and brushing my teeth tastes bad!

    TRADERS JOES pine nuts ARE from China. They’re only packaged in Korea, Russia, or Vietnam. They do that so they can claim they are from those three countries but they are indeed cultivated in China.

    I purchased pinenuts at Longo’s in Oakville Ontario, Canada to take with us on a road trip to New York City. After 3 days in New York City everyone started to complain about a bitter taste in mouth after meals; mints or gum made it even worse. We started to wonder if we caught a swine flu, or other unknown virus. Came back to Toronto to find out that my Mom seek medical help thinking she was having a serios liver problem because of bitter taste in her mouth. I was puzzled and checked the Internet. It took me only a few minutes to solve the mistery.
    I went back to Longo’s to find out where the nuts came from. On a package it only gives the packaging company… The manager of the store was king to call me next day and inform that pinenuts came from China…

    This just happened to me after I ate Chinese pine nuts from Whole Foods (their own store brand, “365”). How could these still be sold when the problem was identified as long ago as 2001? Imagine what it’s like for people whose appetites are already compromised by medication or sickness! And for those who confuse “rancidity” with this problem, they are two different things. My pine nuts tasted fine, which is not the case with rancid food. Do not eat Chinese pine nuts.

    Add me to the list. I had some pine nuts in a salad at a friend’s barbeque on Saturday, May 23. Everything I eat or drink tastes terrible afterwards and this is the second day of the bad after taste for me. I recall she said she got them from Raley’s bulk foods so who knows where they came from.

    a-HA! lasting for weeks, eh? i’ve been nibbling on pine nuts bought from a nice “foodie” grocery store (their bulk bin) for the past few months. who knows how long they’ve been in my pantry. i think just when i would get them out of my system, i’d nibble a few more and here we are again. very sad, because i miss the way food is suposed to taste. 🙂

    thanks for the wikipedia quote and a very enjoyable read. safe pine nutting!

    I too spent the past weekend suffering through “pine-mouth.” I did try the suggestion of eating aloe… my local TJs (curiously the source of the culprit pine nuts) sells canned aloe chunks. After chewing a few pieces several times over the last 48 hours, I am THRILLED to say that the bitter metal taste is 80% gone!

    Seriously, I have never posted to a blog before in my life but I am so relieved to have found this one that i feel the need to reply. I too thought i was dying until i read this blog about pine nuts. i have had stomach issues over the years and figured this was just another disease to add. i was googling “bad taste” instead of “bitter taste” and nothing good was showing up. i finally saw something about bitter taste, and thats when i found the pine nut theory. i made pesto with pine nuts sunday night, and first noticed the bitterness yesterday while eating lunch. i bought mine from whole foods. they are also in my salad for lunch today – guess i’ll be picking them out! cannot deal with this taste anymore..but thanks for solving the mystery!

    Yup, I’ve got that nasty metallic taste too. My pine nuts came from Wal Mart. The nasty taste took about 1 1/2 days to appear and so far has continued for 1 day. I threw away the nut package and don’t remember the brand, but it wasn’t the store brand. I’m heading back to the store tomorrow to check the package and see where these nuts originated.
    I’m in Arizona and, ironically, I bought the prepackaged nuts because I saw a roadside stand with hand painted signs advertising roasted pinons (pine nuts). I questioned the cleanliness of the preparation–sold in burlap bags out of the back of a pick-up truck–and opted for the national brand instead. Even while eating the nuts I was thinking, “Humph, these aren’t as good as I remembered.”
    Think I’ll test my odds with the burlap kind next time.

    Oh, and I know this is totally a dental and diet no-no–plus it would normally just sound gross to me–but I’ve taken to placing marshmallows on the back of my tongue. As long as they’re dissolving, it hides the bitter taste for a while.

    Today I had experienced a very bitter taste in the back of my mouth. I tried everything to get rid of it. I knew it wasn’t a perio thing as I work for a dentist. It was driving me crazy. I asked my daughter to look it up on the internet and she came back with jaundice, medications, perio etc.. I knew it was none of the above. So I did my own research and when I came to this site I finally had the answer. Pine nuts whewwwww so glad for pine nuts. I had a salad the last 3 days that was full of pine nuts which I have never had in my life..It all makes sense now and I can rest easy and stop eating them as that is the worst taste ever. Thanks for the info. I know that I am not going crazy.

    This just happened to me after I ate Chinese pine nuts from Whole Foods (their own store brand, “365”). How could these still be sold when the problem was identified as long ago as 2001? Imagine what it’s like for people whose appetites are already compromised by medication or sickness! And for those who confuse “rancidity” with this problem, they are two different things. My pine nuts tasted fine, which is not the case with rancid food. Do not eat Chinese pine nuts.

    yikes – HOW could this be true? I had brussel sprouts roasted with pine nuts and balsalmic vinegar on Sunday. My taste buds have been history since Tuesday and I had to search because this is so bizarre. I can’t even eat my morning staple – a banana. NEVER again will I eat pine nuts.

    hmmm. Might be the perfect thing to kick of my diet. Eat some pine nuts then eat all my favorite foods.

    After eating pinenuts two days in a row this awful bitter taste after eating and drinking is happening to me as well. Im new to the pine nut thing and did not refridgerate them after opening so I seem to have really done myself in. Mine were purchased in a small sealed bag from the produce section of my grocery store. If I had bothered to read the label beforehand I would not have purchased simply because there was no definitive country of orgin.

    For the last four days, I have had a bitter “hair spray – like” taste in my mouth every time I ate or drank anything. It is annoying! I thought something might be terribly wrong with me. I thought perhaps I needed to go to the doctor. First, I thought I’d try to “google” an answer. I was very excited to read about the pine nuts. I have been eating a lot of pine nuts in my salads lately. It must be the answer I was looking for! I am very relieved. I have purchased them from Kroger and Fresh Market. I’ll need to investigate to find out where in the world they were shipped from. Thanks!

    My evening beer, an essential in kidney function for me, is tasting bitter like the woody parts of pecans. It is definitely in the can, not a residual taste in pockets in my throat. I never eat pine nuts, but pine teas are highly recommended for colds, etc. so I guess the “turpines” they contain might be good for you in some circumstances. Don’t worry, “it’s all good.” Long life and good health to you all.

    My dad came over and was complaining of a bitter taste in his mouth and said that my mom was experiencing the same symtom for the past couple of days…so I googled it and I saw pine nuts as a possiblity.
    I asked my dad if he ate pine nuts and low and behold both he and my mom did!
    Thanks so much for putting this article out…what a great help it was!
    It has put my parents and my minds at ease.
    My dad called a nurse and she thought it could be acid reflux, but for both of them to have had it at the same time and my dad already taking meds for this was weird to me and that’s when I googled. By the way, they got theirs from Costco. Thanks again!

    Am I ever glad I stumbled upon this when I typed “bitter taste on tongue”! On Mayo Clinic and other sites like that, I had panic when it said it could be pregnancy or post nasal drip. As I have sinus problems frequently, I put in a call to my doctor for an appointment.

    Now that I read this – I realize it was my favorite new meal that is doing this to me! Pita bread baked with basil pesto, ground turkey, pine nuts and topped with Asiago cheese. How can something that tastes so good do something this bad? This taste is my mouth is torture… it’s like day old coffee mixed with half smoked cigarettes. Gross.

    Ditto. Bought and Ate Pine Nuts from Trader Joes last Wednesday. By Friday, had horrible bitter metallic aftertaste in mouth after ingesting anything (but water). Looked on webmd for symptoms/causes and got nothing. Was about to call Doctor on Monday after a torturous weekend, but decided to google “bitter or metallic taste in mouth after eating” and got my answer! Unfortunately no one lists any remedies! Just wait it out. I am now on day 5 and it is finally subsiding enough that the thought of food isn’t so nauseating. BRUTAL. I love pinenuts, but I don’t know if I’ll ever risk this again!

    Half of the fun of finding this site is posting and getting the posts emailed to me from others who post next. I agree that I am not sure I can eat pine nuts again..unless I know for a fact that they came from the USA or Italy. There were some antecdotes (sp) listing in some people’s posts (aloe juice was one). I would just like to say that I felt like I had been poisoned.I had other symptoms that most people didn’t experience but I see some others also felt flu like and achey as well as the taste bud issue. After called the FDA I was told by their hack that they couldn’t take a report because I didn’t have the package or remains–we ate them all in the recipe. If anyone has friends in high places could they get someone somewhere to research this and make it public? I send info to Oprah and the networks but no one has responded….ewww. What about Dr OZ? If you know them please ask them to do a piece on this. I think the FDA should pull imported pinenuts from the shelves until they figure what the heck is going on.

    I’m really surprised, but I did eat pine nuts a few days ago (not as tasty as the ones I had eaten before) and yesterday I started with the really bitter taste in my mouth. The pine nuts were indeed from China. Gross.

    I just ate a handful of pinenuts a couple of days ago. Yesterday I noticed that once I ate breakfast, I had a bitter taste at the back of my tongue. It only got worse. Everything I ate during the day was bitter. Then the next day the same thing happened. I don’t know what to eat to not deal with this. Any suggestions? Also, my pinenuts were from Trader Joes and processed either from Russia or Korea, so they say.

    Me too. The pine nuts were from Trader Joe’s in Los Angeles (Silver Lake). My nuts were a few weeks old. I had used them before with no issues, so I definitely think freshness (or lack thereof) is part of the equation. I made pesto with them, and was eating extras by the handful while I made it. I toasted all of the nuts I ate, so it’s not about them being raw. My wife had some of the pesto and has suffered no ill effects. I asked at the store, and they are NOT from China. The package said, “Product of Korea, Russia, or Vietnam”. Sarah above (May 21) said that TJ’s nuts are only packaged in those countries and are sourced in China, but according to the folks in my TJ’s, that’s untrue; I verified that they are actually sourced in one of those three countries. The TJ’s folks were very sympathetic, but basically said to get action, I’d have to email the corporate types from the TJ’s website, which I plan to do. Like some others here, I feel a mild irritation/swelling at the back of my tongue and the back of the roof of my mouth—like a very mild soar throat. I have tried eating aloe, but it doesn’t seem to help. I’m only on Day 2, so I imagine I’ve got a couple crappy weeks in front of me. No way I’m passing on pine nuts for good, but I will definitely be sure they are fresh and sourced either here in the US (New Mexico is a producer) or in Italy.

    How very interesting. Glad I came across the “pine nut” reference, because I also thought I was developing a serious illness. My pine nuts came from Trader Joe’s in Palatine (Chicago area). I’ve been buying pine nuts at Trader Joe’s for years and this is the first time I had this experience with bitter aftertaste. Maybe there was a quality problem in the recent batch? Thanks to all who commented – glad to see i am in good company!

    So thankful to have found your blog. Everything I was eating tasted bitter and sometimes metallic, and I was afraid I was being poisoned by either something I had eaten, or possibly old dental work. I no longer have any mercury amalgams, but I have several old porcelain crowns which contain mixed metals in their base. I recently discovered that porcelain crowns contain aluminum oxide, and dentists have used questionable materials that can be toxic in dentristy, such as nickel. So I was thinking along the line of toxic metal poisoning caused by dental work or mercury from tuna I had eaten. I bought my bag of raw pignolias from Trader Joes in South Pasadena and added a handful to my salad the other night. The package says, “product of Korea, Russia or VietNam.” (Is this like eeny, meeny, miney, mo? Why don’t they specify the country of origin? Also, I did not know that pine nuts can easily become rancid, and there is no indication on the package about refrigeration needed. Thank you for your blog and thanks to all who took the time to post their stories. Glad to know the odds are in my favor that I will live, if the bitter taste is caused by the pine nuts.

    Thank goodness for your post! I bought my pine nuts at Trader Joe’s in NE Portland (OR) a week ago and made a tasty pesto spread for an evening gathering. Then next morning I thought my OJ was off and pitched it- later discovering that everything had a bitter aftertaste. None of my friends are experiencing this phenomena. I’ll have to ride it out and hope it is only a matter of days, not weeks.

    Thank YOU! Last week I began tossing a few pine nuts into my dinner salad. And only recently started having a bitter taste on my tongue. I thought I had acid reflux, heatburn or an intestinal infection… or even worse… cancer… I am SO relieved to discover the pine nut theory. I will experiment and eliminate them from my daily salad. Thanks for posting!! I bought the pine nuts at my local Albertson’s.

    Just a check-in. I am on Day 7 of Pine Mouth (see post above). The taste is still around, although not as bad. I hardly notice it with some foods, but it jumps out with others. I haven’t found anything consistent that triggers it. I am still having some minor irritation/discomfort/swelling at the back of my tongue/throat. Want to point out to all that my pine nuts were roasted, so I don’t think it’s about them being raw. I think it’s about source and/or time since the package was opened (3-4 weeks, in my case).

    I also Google bitter taste in mouth and thankfully found your website..
    We had dinner at The Cheesecake Factory last Sunday and I had
    Evelyns Favorite Pasta.. on Tuesday the milk tasted bitter, but it
    was the end of the gallon so I thought it was a little sour. Then
    everything tasted bitter. I chewed gum and brushed my teeth but
    it didn’t go away. On Wednesday I had a banana for breakfast
    and immediately got the same reaction.. it lasted all day… Today
    I woke up bitter free… until I tasted a few grains of barley that I am
    cooking for a recipe… the bitter taste returned instantly… Thoughts
    of brain tumors flashed through my mind until I found your website..
    One would think that a busy restaurant would not use rancid nuts..

    Needless to say, Evelyn’s Favorite Pasta is no longer mine…
    Hope this goes away soon.

    Mine lasted 2 weeks…decreasing as time went on.
    I went out the other night and the restaurant had fabulous bread with
    a green creamy spread. Not until I ate some did I realize it was a creamy parmesean pesto. I freaked for a minute. Then continued to eat it…nothing so far and it has been 4 days. Last time it too 2 days to show up with bitter. I think I am ok.

    I didn’t think I would ever have the nerve to eat pine nuts again..but they snuck up on me.

    Was at a wedding last nite, I told my wife the chicken tasted off – she said hers was very good….. This morning I had OJ and was going to spill it out because it tasted bad. Then I had cereal & milk, coffee & muffin and realized it was me – everything tasted bitter. Just had lunch and everything was awful! So I goodled “everything tastes bitter” and found this site.

    Had a salad with pine nuts on Saturday! Glad to have found the probable cause, but can’t wait till it passes!

    I made my own pizza Sunday and sprinkled plenty of pine nuts on it. Tuesday I had the bitter taste after eating anything. I don’t know where the pine nuts were from and I like them but I don’t need the aggravation of the bitter taste. Pine nuts goodbye! I’m glad I found fellow sufferers so I know what is going on with my taste buds.

    Trader Joe’s pine nuts, too. Tasted fine when eaten. Bitterness set
    in two days later.

    I have had pine nuts from Trader Joe’s many times and have handled
    them the same way. This is the first time I’ve had problems. That
    suggests the problem is with this particular lot.

    I just wanted to clarify for those of you assuming that the problem with pine nuts is isolated to Trader Joe’s (or some other store solely). It is happening and has been happening per the googled posts I have read for several years in stores across the nation and the world. TJ’s – Whole Foods-Stater Brothers-you name it..they have been purchased all over. Seem to be coming from China though it also shows other countries on the packages of some. Korea, VIetman etc–not sure if they are all from one place or not. FDA would not take a claim because I didn’t have the package or the remains. I felf poisoned by this..more then annoying I was actually sick for a few days. Maybe there is a problem with the pine trees grown where these are harvested…pollution–pesticide?

    ME TOO!!! This happened to me 2 months ago with some pine nuts from Trader Joe’s. I thought it was a sinus infection and took 10 days of antibiotics, during which time the bitter taste faded away very gradually. The bitter taste drove me nearly insane during that time. Like everyone else, I googled my symptoms, read about the pine nut link, realized that I’d just made pesto with some pine nuts from Trader Joe’s — but it seemed like such a weird connection, i discounted it. i’ve been making pesto for years and never had a reaction to pine nuts before. (Of course, we just got a Trader Joe’s here, so I hadn’t bought pine nuts there before.) Just in case, I threw the rest of those pine nuts away. Fast forward two months. The basil in the garden is ready to be harvested. We have no pine nuts, so I asked my husband to pick some up on his way home. He got them at Trader Joe’s. Assuming my last bad experience had been a sinus infection, I went ahead and used them. Today, I can barely stand to eat or drink anything. I’ve been panicking today, wondering if I have gastroesophageal reflux, or cancer or an abcessed tooth. For the hell of it, I checked google once more and found this page. Pine nuts are totally causing what i have — my symptoms are EXACTLY what everyone else describes. I HATE this. Has anyone found anything at all that helps??? I can’t stand to go through this all over again.

    OMG, I am dying from this horrible taste in my mouth, all day today, and yes I did think of brain tumor, I have been munching on pine nuts since wednesday, and I bought a big bag from Costco. I love pine nut and I have been eating them since I was a kid. Thank you so much for putting my mind at ease, I would have never ever thought of pine nuts.

    Wow! Thank you! I ate about 1/2 of a small bag of pine nuts yesterday and today everything tastes awful (like a strong aspirin taste at the back of my mouth). I was beginning to wonder about the brain tumor thing too! My pine nuts did not come from Trader Joe’s (Fresh and Easy market).

    THANKS SO MUCH FOR THIS INFO!!! I was going crazy!!! I made my first pasta dish with pine nuts over the weekend. Then yesterday everthing tasted horrible. I couldn’t eat dinner. The bitterness was horrible. Then this morning the same thing. I was so concerned and was reviewing everything I recently ate. When I saw your story I was so happy!!! I thought I had a nerve or neurological problem! I just ate lunch and it’s starting to get better. Thanks again!!

    Wow, thanks so much for the post. It was the 3rd result when I googled bitter taste. I have been having this bitter taste since yesterday at at first I blamed it on Costco milk, then I noticed that all my food had this bitter after taste in the back of my mouth. I had bought pine nuts from Costco $16 for 1.6 pounds, about 5 days ago and have been eating them straight and on salad, etc… None of the other people in the house, 3 of us eat pine nuts, have had this. I have the spinach thing that one of the other comments mention, along with a variety of other foods, I still eat them. I think it may be a sensitivity to the older oils. I believe I’m a super taster and maybe this is another symptom.
    I’m glad it is not permanent and I got a non medical diagnosis. I am the American hypochondriac also.

    Mine from Target in Savage, MN. I do have packaging and some left over.

    Good post. Oh how I love the internet. Anyway, I have not had pine nuts for many years until I went to Safeway and bought some. I ate them Mon, Tue, and Wed. The taste started mid-day Wed and is still there today (Thursday). At any rate, glad to know I am not dying :-). Lesson for me – next time, buy quality, not quantity!

    Down to Earth on Maui, Hawaii. I found mine refrigerated at their store. I called them on it and Sarah, the store manager, said they were Chinese.

    YOU ARE AWESOME!!!!!!!!!!!! I was freaking out after My july 3rd party with the outdoor yard party with grill. I blamed on the grill, the coal and the grazed Buttercup plants for my horrible BITTER taste in my mouth!!!! I am a good cook but all my food tasted like Bittergourd!. I am glad that this PINE NUT finally came up after 2 hours of my serious and heartbreaking search for my bitterness. Google freaked me.
    Then I realized…i ate the MOST pine nuts with my organic salad and raspberry sauce!!! and I ate them for 2 days in a row and bang! I taste bitter, bitter, bitter for the past 3 days . Even my favourite Grape juice taste bitter. THAT scared me off. Thank you so much for this article

    I am so pleased that after typing in the phrase “after eating food I have a bitter taste in my mouth” I came across this site. I too have been eating pine nuts- from an Australian company 100% owned, which packs nuts from China. It started this morning when I thought my egg was off, so tossed it out, then I thought my toast tasted bad and decided it had to be the butter..out that went, then I just had toast, and you guessed it that went out too. Everything else has been the same, steak and salad tonight was just awful.The only positive I can see is that in the two or three days it should last, I will dislike the taste of food so much that I eat less and lose a few kilos. Every cloud has a silver lining so they say.

    Okay, so we at least know it’s not life threatening! A phenonemon? When do you think they’ll figure out why this happens? Nut allergies can kill you! We’re all alive but WTF? This is now my new quest in life! Why do pinenuts cause a bitter taste on the back of the tongue? I’ve been eating them all of my life! I’ve cooked with them in my restaurant. This has never happened to me? The pinenuts I used for my pesto had been in the fridge for a few weeks in an effort to keep them fresh. I even used them in a salad weeks ago and did not have this problem. Will someone put someone in charge to figure this phenonemon out?

    Well I reported before that I reported it to the FDA and they weren’t interested in pursuing it since I didn’t have the bag–even after I told them about this and the other blogs on the internet. I called the poison control center and no one called me back-I send emails to the major news networks and local new stations — also sent one to Oprah’s people.–Nothing. So I would love for somene who knows someone to get this ball rolling. It can’t possibly be good for you it happens. I felt poisoned.

    I was wondering what was wring with me. A metallic taste, especially with sweet food even granola, almost anything. Coconut fruit bars by frutstix seem to be the only thing that tastes normal. Carrot juice, no but tea is fine. I ate pine nuts 2 days ago- so I am sure I got the pine- nut problem. Hope it ends soon, its soooo weird. The taste is awful, and didnt show up till a day or two later. It tastes like poison. If there is a lawsuit, please add me. Thanks for solving this terrible mystery.

    I got to this site today cause I have a horrible case of bitter taste syndrome, it really freaks me out, I have not been able to eat since yesterday I txt my doc and he told me it could be Gall Bladder or acid reflex so i got on google and found this site, and to my surprise I found Pine nuts which I had eaten the day before yesterday and try to eat yesterday with my salad, but just couldn’t finish cause everything taste horrible…I hope that this is it….this is driving me NUTS:)

    I am from Sydney Australia and yes Pine Nuts are causing a bad after taste for me. I have had all the symptoms described in the article. And yes the Pine Nuts were fom China. I have had the bad metallic taste for 4 days now. I found I can eat sweet foods, without experiencing the bad after taste as much ( for example chocolate and sweet jam on toast) but nothing savory, and NO WINE :(. Shouldn’t these Pine Nuts be illegal?

    I’m from the U.K. and I have to say a MASSIVE thank you to you all for solving my bitter mystery. I’ve been using a lot of pine nuts in my cooking over the past few days, and snacking on them quite a lot too. I just ran downstairs and low and behold my packet said ‘PRODUCE OF CHINA’. They’ve gone straight in the bin and I guess now I just have to wait and see how long this horrid taste lasts. I’ll keep you posted if I find a remedy to it.

    Remedies: pinch of salt, vinager, natural lemonade,orange juice. And I really enjoyed Hot salsa n salty chips without a bitter taste.

    Thank you! I was convinced there was something seriously wrong with me! I purchased a bag from whole foods last week and made a huge batch of pesto. I have also been nibbling of of the bag a little everyday since I LOVE pine nuts. I bought the 365 everyday value brand – with a huge ‘product of china’ label on the back. Scary!

    I had this problem last month… I had Evelyn’s Favorite Pasta at the
    Cheesecake Factory and it has pine nuts.. What worked for me after
    3 days is remembering that TOMATO JUICE takes the skunk odor
    off of dogs… so, I thought… why not give it a try. I had some V-8
    juice in the house and I slowly drank the 12 oz can…also gargling
    with it and letting it sit in the back of my throat for about a minute.
    I can’t guarantee that was the reason… but the bitter taste was a
    lot better after the TJ treatment and completely gone the next day.

    Thanks so much! I was worried about all kinds of terrible conditions (throat cancer-I’m a sometime smoker, to sinus infection-I’ve never had sinus problems…) and have had this terrible bad taste in my mouth for days, esp. upon waking in the morning. I had started eating pine nuts (from China) because I saw one of Oprahs docs recommend them. But no more pine nuts for me! This awful taste is not worth it!

    I, too, have experienced this problem. But, since there have been several people who mentioned that their friends/family ate the pine nuts as well without any consequences, it is likely that the pine nuts may have an ingredient in them (some kind of oil) that is reacting to the chemical makeup in our bodies. It is also possible that since China is such a huge producer of pine nuts, the likelihood of this happening to someone after eating pine nuts from China (vs. New Mexico, USA where production seems to be non-commercial) will be much greater. There needs to be a study on the the varieties of pine trees and occurrence of this, too!

    Just found out that over 90% of the supply of Pine Nuts come from China and that the nuts are not coming from trees that are commercially harvested so that rules out any fertilizers or pesticides….

    Just happened to me too. The pine nuts I ate were from China. No more pine nuts for me. It’s been 5 days that everything taste terrible.

    I am having the same bad taste as everyone else and my pine nuts came from Dell Alpe, distributed by Rubenelli. The container doesn’t say where the pine nuts are from, I will have to pay more attention in the future. By the way, my wife ate the same pine nuts with no ill effect, which is good because she is already pregnant.

    Hello! Friday I made pesto and used some pine nuts I stored in my freezer. Of course, while making the pesto I snacked on a few of them because I love pine nuts. They tasted great! Saturday I started having a strange bitter aftertaste in my mouth after I ate anything and I thought it very odd. This is the 2nd day and my symptoms are continuing so I started researching the causes. Lo and behold, after reading all the comments here I’m jumping on the bandwagon because I think those nuts are the culprit. My package of nuts says they are “a product of Siberia” and “best if used by 4/18/09” so, yes, they could be considered “expired”. I had them stored in my freezer to keep them fresh for a longer period of time. The pine nuts are distributed by Valued Naturals, Dover, NJ 07801. I’m heading over to the FDA site to see if there is any mention of this weird pine nut aftertaste.

    Dear Biologie
    Please keep us posted about your interaction with the FDA. Because I didn’t haave the package left they would do nothing–even after reading this site. I hope someone does something about this.

    We are on day 3 of ‘terrible tastes’ after eating a pesto pasta with extra pine nuts. 3/5 of our party have the bitter taste which started on day 2 after eating the nuts. We got our pine nuts from Tescos in Ireland! not sure where they were from, but we used them the day they were bought, so I don’t think it has anything to do with freshness. There has got to be some way to reduce the symptoms. I have noticed that sweet things definitely make it much worse. Please post solutions if you have any? Will try the tomato juice gargle (yuck!)

    I just ate some pine nuts from Trader Joe’s two days ago that had been sitting around, and now I’m getting the same symptoms. If I see those berries I’ll try them out, but I don’t know if it would really cure the problem, or just temporarily distract you from the symptoms.

    This happened to me a couple of months ago with some hummus with pine nuts from TJ’s. I found something online that mentioned the bad taste/pine nut connection. I had some pesto in the fridge (also TJ’s) and just tasted the spoon after stirring up some pasta salad. The bad taste was back with a vengeance the next morning, and that was just tasting the spoon! I don’t recall the pesto bothering me earlier, either.

    ACK! Me too! Mine were from the bulk bin at my local Hy Vee. They had such a sweet taste, which I’m learning now is probably indicative of their rancidity. I just had 10 or 15 of them total since Saturday! It’s now Friday and my symptoms started yesterday. Stay away from breads, orange juice, and everything else that has a flavor! The only thing that hasn’t tasted like rubber bands so far is whiskey. So I’m planning to keep some Maker’s Mark closeby all weekend 😉

    Hi there,
    I am experincing very similar things right now! I started noticing this bitter taste at back of my mouth about 24 hours ago…I cannot seem to figure out why???? Today the symptom persists…it is MOST obvious when I eat sweet things (fruits, ice creams, etc). I also noticed there are a lot of article linking pine nuts with this bitter taste, however I only had a very small amount of pine nuts earlier this week inside chicken hummus. I am not sure if this is the reason cos I had the same hummus MANY times before and never had the problem. I do however purchased some pistachios nuts and ate them all earlier this week, which I do not do often….Now I am wondering if the pistachios nuts will cause the same problem????!!
    Any suggestions would be really appreciated!!! THANKS!

    365 Brand from Whole Foods Market. They took back all three unopened bags. Though the people at customer service desk hadn’t heard about it, the people at the Austin HQ had had numerous calls. I reported it to the FDA last week and they have apparently been getting lots of calls. And yes, they were from China. And no, I do not think they were rancid. I ate some from the bag before we used the rest to make pesto and they seemed fine.

    When I was in Trader Joe’s today in Valencia Ca I asked the service desk if they had had any complaints about the pine nuts. He said he hadn’t heard of any personally but he said that they had stopped carrying things from China over a year ago. He said not just food products but even the recyclable grocery bags that they sell. Still wondering why no one has taken this more public..

    I finally got over that bitter experience 2 days ago. It lasted 8days! Now I’m trying to convince the chef where I work, (not where I came in contact with the culprits) to get rid of a big box of pine nuts they use in some recipes. He said he won’t be making pesto any time soon! He did contact the exec. chef to see if he had heard of this and he had not. Now my co worker chef wonders if this is all a scam(online) and of course I told him to take a handful of the nuts and see for himself. He would’nt do it.
    I do know that some folks don’t have the reaction we have. Lucky us! If i had enough ink in my printer I’d print these pages and show him. I am warning my co-workers and everyone I know to be aware of pine-nuts. peace

    Have been eating pine nuts from Costco in my salad almost every night for years. Then last week I ran out and a friend picked up a bag from Sams. I noticed that the bag appeared different then the one I was accustomed to and that the pine nuts appeared smaller and a little darker, but did not think anything about it until I noted the bitter taste after eating anything. I googled “bitter taste in mouth” and found your site. I immediately looked on the bag and it said packaged in one of the states but down on the bottom of the bag it said “product of China” in very small print. We took the bag back to Sams, got our money back, but they didn’t seem the least bit interested in the problem. We need to pursue this. Thanks for your help.

    Three days ago I made the most delicious pesto, adding some lemon zest to the old standard with basil and pine nuts. Pine nuts from Costco. You know the rest of the story. The bitter taste drove me to google the symptoms and to this page. It’s
    the first time I’ve had this extremely unpleasant experience. My husband is symptom free. Weirdness!

    Thank you SO SO much for posting this!! I have had this exact thing for 2-3 days! I hardly ever google medical symptoms, but this was making me desperate and I felt like an idiot calling my doctor asking about the bitter taste in my mouth. While scanning the results, “pine nuts” jumped out at me! I hardly ever eat pine nuts, but bought some to make pesto. After making (and eating) the pesto, I ate the rest of the jar over the next day or so. I just got the jar out of the recycle bin, and sure enough, they came from China!

    Seeing so many people here who have had this makes me feel better. At least I know I don’t have some strange fatal disease!! I will just wait for it to go away, now that I am pretty confident that it will. As anyone who has experienced this knows, it is quite annoying to say the least. It is no fun to eat your favorite foods–they all taste bad!

    I, too purchased pine nuts from Trader Joe’s and have been experiencing that bitter taste after eating and drinking too. It seems as though it only affects the taste buds at the very back of the tongue, that’s probably why it happens after swallowing, not chewing. It’d be great to find some type of simple remedy for this, but it seems as though it just takes time for the taste buds to recover.

    I too ate pine nuts from Trader Joe’s labeled from Russia, Vietnam or Korea and I have had this bitter taste while and just after eating for several days now. It is only in the back of my throat as well. Good to know I’m not getting a horrible medical condition, however, I’m disappointed I can’t eat the rest of the delicious pesto I made with the pine nuts and certainly won’t be buying them from Trader Joe’s again!

    I was so happy to read your “Pine Nut” article. My husband and I ate a bunch of pine nuts Thursday night and woke up with this bitter, awful taste in our mouths. We too ate animal crackers this morning and we swore that they had gone bad. We checked the expiration date, but it was well into 2010. This went on all day today while eating lunch, snacks, dinner too. At one point I gargled with vinegar thinking I would neutralize whatever it was going on. Well, what can I say.. vinegar disguised it for a while (yuk), but it came right back. Even as I sit here drinking my wonderful Merlot, it tastes like hell. Now I can rest easy and stop thinking something is wrong with me. LOL, you solved the mystery. Thanks!

    After making pesto last weekend (and eating pine nuts by the handful!) I have been experiencing these same symptoms for days… google searches led me here. I noticed your original post was early May, and I bought my pine nuts from Sunflower Market August 14th! Why were these never pulled from the shelf?
    All that basil, gone to waste!

    For those who have suffered, or new posters, please come back when the taste is gone and put down how long it lasted. It seems this phenomenon is especially pronounced this year, perhaps due to stockpiling of pine nuts in China. It’d be useful to have a concensus on how long the taste lasts so other folks who find these blogs know what to expect. I’m on day three right now and will come back and say how long it lasted once it’s over. Note that if green tea is useful (and I’m finding it is) that an anti-oxidant pill might help.

    Thank goodness for this blog. I had an awful case of this, and nearly checked myself into the hospital until I googled the problem. I gargled three times with a mix of balsamic and rice wine vinegar and drank it afterwards and have to say my pine nut mouth has almost disappeared. I was day 5 into it and maybe it was going away on it’s own but it’s worth a try, and a pretty good antioxidant I hear. I would have tried anything my case was so bad. Good luck to all

    It appears, so far as I can tell, that the problem lasts about four or five days and then gradually disappears. I went back to where the pine nuts had been purchased (Sam’s in Charlottesville) and spoke to the manager about the problem. He seemed to be interested and appreciative, but, alas, after about a week, I have noted that the same pine nuts are still on the shelf. Watch out for pine nuts from china or the orient.

    I got some from a local grocery store. Roasted them and made pesto – plus just some roasted nuts. Two days later, I though I had gotten a contaminated box of cereal. I was considering going to the ER for poisoning. I searched and ran across several comments about this. I wonder it is is something in the soil or the type fertilizer.

    Anyway, on day 2 of metal ass mouth.

    I suspect I’ve got a case of pine nut bitter mouth syndrome–thanks to the creators and posters of this page for helping uncover this peculiar phenomenon. I had a cheese plate that had raw pine nuts at a museum cafe this weekend in DC and about 36 hours later, I started to get the bitter taste whenever I ate. I’m now about 72 hours out from when I ate the nuts and am relieved that this should eventually go away on its own, but will try to remember to post when it does. Not sure where the cafe gets its pine nuts, but I will try to find out. Thanks all!!!

    I am also having a problem with a bitter taste after eating pine nuts. And what do you know? I too bought them at Trader Joe’s, made pesto, and ended up with this annoying taste. I eat pine nuts all the time but probably will not in the future because I’m not sure it’s where they came from but the nut itself. However, I was shocked to see that the packaging was not clear as to where the nuts came from but only indicated Russia, Vietnam or Korea. I’m looking forward to tasting food again.

    As promised, just wanted to report back that the bitter taste is finally gone, after about four an a half days of bitterness. Yuck! I was never able to track down the source of the pinenuts I ate, but I suspect they were probably from Trader Joe’s and were the infamous Chinese ones people keep talking about on this site.

    me too.
    got the bitterness on a friday night, unbearable on saturday and sunday when researching om GERD (Gastroesophageal reflux disease) i came across the great Pine Nuts Conspiracy. I have been eating pune nuts forever and never had an issue. but then i realized that on the previous wed night i did eat a handful of chinese Costco pine nuts, stored in a cupboard at room temperature for weeks (like i had done n times before).
    i am a believer now. by tuesday it was much better and by thursday everything was back to normal.
    so in my case was to day to set in, and 4-5 days to go away with only 3 really bad, so hang in there!

    I made pesto Monday evening and all day today (Wednesday) have had horrible bitter taste with everything I eat. I picked my daughter up from school and she said she was starving as she couldn’t eat her packed lunch as everything tasted “yucky”. I bought the pine nuts at the local grocery store (Tesco, Cork, Ireland) but don’t know where they came from as I binned the packet. At the time they tasted lovely and my sons were picking at the left over nuts though neither seems to have this symptom of horrid bitter taste. Am now about to call friend & husband who ate with us. This is all most interesting, thank you.

    Yesterday I was eating a cup of ramin noodle beef soup for lunch. After about my 2nd swallow I had a disgusting aftertaste in my mouth. I figured maybe I’d had the soups in my cupboard for to long and threw them out. From that point on everything I put in my mouth tastes horribly bitter. I too called the dentist and made an appointment that I’ve since cancelled. After Googling “foul aftertaste in my mouth AFTER eating”….bingo…pine nuts !!! My girlfriend made a delicious pasta and broccoli dish over the weekend containg: drum roll please………..PINE NUTS !!!!! Her’s came from the local A&P. I ate the poison dish on Saturday and now its wednesday and everything still tastes bitter. Someone posted here that beer seemed to taste OK.

    Yes, pine nuts. Goggle, and one learns. FDA problem!! We eat pine nuts lots. This is the first time I have ever experienced a problem. Refrigerator, new unopened bag from Valley Finest, packaged, Fresno, CA 559-266-4849, bought at Save-Mart. bar code 7 28813001181 just recently. Perhaps, the wholesale place where these were bought from uses insecticides around the storage containers…or, maybe the nuts have been treated with some kind of anti-bacterial “something”,
    or maybe just one bad rancid nut, spoils the whole bag? What is FDA waiting for to pull all of these from the world market. Who knows what damage takes place, we might not know for years. Or, maybe we got lucky and we will all be healthier because we ate them:)

    A follow up…I ingested the poison pine nuts on Satuday. As I type this it’s the following Friday night (just got back from Cruefest 2 @ Montage mountain PA) and I’m happy to anounce that the disgusting bitter taste is about 80% gone. I can still detect it barely…it’s not gone, but now I can eat without wincing. A couple notes: bread and iced tea seem to be the most horrible of things I consumed while poisoned. Salad and diet anything seems better as sugar is also grotesque. I also had a sensitive skin thing going on…kinda like having sunburn without the redness. Anyway only Italian imported pine nuts for me from here on out !!

    Wow, I am amazed. I have been experiencing the awful bitter taste for about a week. As it continued I started to think something was wrong with me.

I have been eating them constantly…I can’t wait for this to go away! Blech.

    Anyhow, I bought mine at Trader Joes and keep them in the cupboard with the other nuts not the fridge, but no more. Thanks for the great insight, so good to know!

    This happened to me in Iceland, me and my girlfriend’s family were all having this weird bitter taste in the roof of the mouth, we had no idea where it was coming from, we started to think that it could be the water or the milk, but after reading this blog i remembered that 1 day before it started, we ate raw pine nuts, and also we ate them in some chinese recipe that i cooked, i’m not sure if the pine nuts were from china but there is a big chance that they were (they were really cheap), i feel better now knowing were it came from, thank you! :).

    Same effect here. I have been buying pine nuts from Trader Joe’s for years and never a problem. My husband decided to make dinner a few nights ago (first time in the 13 years we’ve been married!) and purchased some pine nuts from our local grocery store. 2 days later, terrible bitter after taste no matter what I eat. My research indicates that it is not any chemical treatment or pesticide residue, but more likely the species of pine tree from which the nuts are harvested. Different species in China than in America or Europe. I have notified our local independently-owed grocery store, and based on the other comments will now check the source no matter where I buy them!

    This is definitely the strangest thing ever. I just noticed the bad taste this morning and I had Pine Nuts 3 days ago on a salad at home. I always keep the nuts in the freezer. I feel like I want to keep eating things to get rid of the taste, but then it gets worse after I eat . I’m a dental hygienist and I have tried brushing my teeth and tongue many times , but that doesn’t help either. I think I’m going to return the nuts to Trader Joes, although I do eat them often and in a lot of recipes. I have never had this happen before. Never would have imagined that something I ate only a little of and 3 days ago would just start this bad taste today.

    My wife and I consumed pine nuts from our local New Seasons Market bulk section located in Portland, Oregon. We ate a dish containing these pine nuts on day 4 of a 5 day backpacking trip (not refrigerated). I noticed the bitter taste in foods about 24 hours after eating the suspect nuts and am still experiencing this (especially with sweets) 48 hours after consuming. My wife has similar symptoms but not as strong as mine (no major taste distortion for her, but a bitter aftertaste).

    Glad I found this site! I bought bulk pine nuts (have to go back to the store to check the country of origin) and made pesto this weekend. Of course I ate handfuls of pine nuts, raw, during the course of the afternoon. My symptoms started Sunday evening. By Monday the bitter taste was full-blown. I thought I was coming down with a cold!! Glad to hear that the bitterness isn’t sinusitis (or worse). I’ve been reading entries trying to find someone who has posted a remedy. I’ll try the tomato juice/V8 option as soon as I can get over to the cafeteria here at work and report back! I know that salt neutralizes bitter…I’ve been dipping my finger in a salt packet for about 10 minutes or so…not a long-lasting cure but it does give moments of taste-bud normalcy!

    I’ve been having the same symptoms for 3 days (bitter taste when eating). I thought it was from antibiotics that I just started taking, so I stopped the antibiotics. But the bitter taste remained. I did an internet search to see if this was a common side effect from the antibiotics, and it was not listed. Then I found a few topics on the pine nut and bitter taste connection. Sure enough, I had pine nuts in my salad 2 days before I noticed the symptoms. And where did I buy the pine nuts? Trader Joes. I’ve had pine nuts (not from TJ’s) before and never had this problem.

    Update on tomato juice to neutralize bitter sensation: I can’t definitely say that it works. I tried a V8 in the afternoon. Tasted gross. Found some straight tomato juice in the evening and had a cup. That too tasted horrible.

    It’s day 4 for me post-pine nuts. It seems as though the taste isn’t as strong. It’s definitely lessened on the right side of my tongue but still present on the left.

    It’s now been five days since my last raw pine nut. Yesterday there was no forgetting the situation, but today the bitter taste is beginning to fade. I’m optimistic it will be gone soon. Also, my sister ate the same pine nuts with me and never developed the bitter taste. I will never eat pine nuts from China again. In fact, before this happened I had no clue that we were importing pine nuts from China.

    It’s now day 6 since I ate three handfuls of pine nuts. Most of the bitterness is gone now. I still get a little twang of bitterness every now and then but I’m glad it’s this good! I’ll be very careful from now on to check on the country of origin from now on. Glad I found this information!!

    Ah… now that makes sense with Pesto season in full swing. I remember that when I snacked on pine nuts, I thought that they tasted the most bitter/horrible of all that I have been eating lately. And it explains why my family and some friends have been experiencing it as well. Makes better sense than the explanation I found online of head or neck cancer.

    this has never happened to me before, but i am noticing it too after eating some in a salad this weekend (which i brought as a dish at a potluck!) the most frustrating part is i went out of my way to purchase them from the natural foods section…. which means “minimally processed, free of sulphites, articial preservatives, colours, flavours.” 🙁

    and anyone else who has been pine nut poisoned in a group setting–Make sure you get the word out to others who ate of the poisoned fruit (okay nut!). Save them a trip to the Doctor’s office and let your host know so someone can send an email out to them with a link to this site. I sent an email to Trade Joe’s corporate office recently. I only think it is fair that they know that people are talking about them here. Grocery stores that have been told have not stopped selling the tainted imported brands from China and the Far East. I am waiting to hear back from Trader Joe’s. I am hoping they are more proactive after seeing this blog. I wrote to the news depts of the networks and the Oprah Show-poison control center and the FDA…no response.

    American pine nuts, DO NOT have this problem.
    See A person has to peel the pine nut, but its is not much of an issue. The nuts are also called Pinyon Nuts but it is a pine nut, nonetheless. The site offers them straight from the forest.

    I found this blog after googling my taste disturbance, and now I’m relieved to find that it might have been caused by pine nuts. Two nights ago, I made a broccoli dish that contained a fair amount of pine nuts, and then last night my favorite wine tasted bitter, and then everything else tasted equally bitter. This morning my eggs and fresh figs tasted bitter, and just now my lunch tasted bitter. I don’t eat pine nuts much at all, and the one time I did was 2 nights ago…

    Thanks for sharing.

    I have been following everyone’s emails regarding the pine nuts. I too ate pine nuts and experienced the bitter taste about 24 hrs later. I am curious though how many of us had been recently to the dentist, via a filling or root canal…or, were on an antibiotic recently – it might also produce the bitter taste. Just a thought, as I was at the dentist and both the antibiotic and the “shot” for putting the tooth to sleep were new products to me, and, both were also very bitter. It might be a side-effect, or, totally unrelated…as I did eat pine nuts, but, I have eaten this brand before with no bitter taste.

    Thank goodness for finding this blog when I googled “bitter taste in my mouth.” !!! I have been snacking on pine nuts, almonds and dark chocolate at work all week. They too are the infamous pine nuts from Trader Joes and they have been stored poorly in the cabinet, and in a baggie at work. I was relieved to find this as being the cause of this awful bitterness to everything I eat and drink because being the hypochondriac that I am I thought something was seriously wrong with me…but this explanation really makes sense….now I just hope mine doesn’t last for weeks…

    I too am having the symptoms. Pine nuts from China bought at BJ’s. I decided to tell the FDA. I went to their website and found the phone number for my area and reported it. They have data collection ongoing on the subject and were happy to add me to it. May I suggest you all report your incidences and symptoms. I’m taking my nuts back to BJ’s and asking for my money back and request they remove the product from their shelves. I was that close to going to a Doctor and what a waste of time and money that would have been. Thank goodness for the web and you all but lets get this contaminated food out of the marketplace.

    You solved the mystery!! My husband just bought pine nuts from Trader’s Joe’s last week and I put them in my salads all week. starting last Thursday I had this bitter taste in my mouth accompanied by a headache(I never get headaches). I have had a problem crown/root canal and was sure it was the cause or had a more serious problem-you have put my mind at ease. The bitter taste is starting to resolve as well as the headache and I am ditching the Trader Joe’s pine nuts-I will only eat Italian ones if any. Thank god for Google!

    Thank you for solving my mystery! I’ve eaten pine nuts before but purchased them in the cooking nuts aisle. These I purchased at a natural food store. Last Wednesday, my friend Marcy and I ate quite a few of them during a web conference.
    She and I just saw each other tpday and we realized that we had the same symtoms for having a terrible bitter taste every time we ate anything. We both started with the symtoms on Friday. We went through a list of what we ate that day and zeroed in on the pine nuts and found this web site. That explains it!

    I was thinking I was going crazy with this bitter taste in my mouth everytime I ate or drank something and no-one else in my family was. I even went to the dentist today and he suggested I may have a gum infection. Anyway, after searching the internet when I got home and finding this stie, I remembered I ate some pine nuts a couple of days ago. I must admit they have been in the cupboard for a few months now, but still ate a small handful.
    I am glad to see that I will survive this, hopefully sooner rather than later. Although the headache is driving me crazy.
    The dentist did advise though to rinse my mouth out regularly with wam salty water and after trying this I can certainly get rid of the taste for quite a while afterwards. So at least I will not starve until it wears off.
    I live in Australia, so I think it is probably old, badly stored pine nuts that affects some people and not necessarily where they are from.

    I did some more research on pine nuts and because they are a fatty nut, they oxidize shortly after you open the bag and they don’t keep. Guess I should throw out the pesto I made as well.

    Yesterday, the bitter taste finally got to me and I had bad stomach cramps and a sour stomach as well along with the headache. I did sleep it off and today the taste is starting to fade.

    same here….similar stories to everyone else…and I bought my nuts at Trader Joe’s as well. Usually I buy their toasted ones and have never had an issue, this time it was a new batch of untoasted ones, I dumped a large handful into my orchiette with broccoli last week, and for the last two days have had that horrible bitter taste in the back of my throat whenever I eat. Of course, I watch way too much “House” and was fearing the worst, fortunately I found this blog and others reporting the same thing. These nuts really should be recalled.

I thgought I had something serious condition going on. Over the weekend my wife and I made pest as we do every year and obviously pine nuts is one of the ingredients we use for the pest. I ate a good hand full over the period of 2 hours or so and it wasnt till the next day that I developed this terrible bitter vtaste in my mouth. Obviously I would have never connect the pine nuts to this…..I’m so glad that I read all these blogs. The million dollar question is, What is the remedy to this?

    YEP! I’ve had the bitter taste syndrome, too. A very bizarre thing–comes flooding in after everything I eat or drink. I found your article by googling “bitterness” and “back of mouth.” Lo and behold, I had eaten pine nuts two days ago. We bought ours at Sams, they were from China, and we happened to have stored them in the back of our Jeep for a few days. Hmmmm… Thanks for the article.

    I am relieved to learn that the bitter, metallic taste in my mouth is not related to a serious illness but instead to the pine nut. I was frantic over the weekend because of the unusual taste in my mouth which is heightened when I eat or drink anything. Not knowing what was causing this strange sensation, I went to Google and almost immediately found my answer. I immediately recalled the handful of pine nuts I consumed as a snack a few nights ago (normally I just sprinkle a few toasted pine nuts on a salad and call it good) & realized that I, too, had been a victim of rancid Chinese pignolias. Although the symptoms are mild, I also have some stomach cramping and a nauseous feeling. The only food I’ve been able to stomach is plain white rice (not without a bitter taste sensation but not as dramatic as other foods) and plain water! This experience has been so unpleasant and scarey that I will NEVER touch another pine nut. In my book, they’re really not that good anyway– just fashionable– and I don’t have time for the pain!

    7:46 am  Oct 5th, 2009
  209. Claudette


    Two of us ate them at work. I got really bad cramping that accompanied the bitter taste. A co-worked got headaches and bitter taste. It took over a week to get rid of the bitter taste.

    They are not worth it!

    I told the store manager at Shaws in Maine and he said he could not do anything unless I had the batch number, etc. (I threw the rest away) He told me that next time I purchase some and I get this reaction that I should keep the packaging. Oh duh! Why would I purchase some more?

    I made a recipe on Friday night that contained pine nuts my wife bought at Trader Joe’s in Fairfax, VA. We ate a couple of them raw and used about half a cup of toasted pine nuts in our recipe. On Sunday I began to notice a horribly bitter aftertaste in my mouth after eating or drinking anything. Since I have never experienced this symptom before I thought something was really wrong with me and resolved to schedule a dr. appt. if the problem persisted for a few days. Thank God I found your posting. I was really starting to freak out. My wife is not experiencing this problem even though she ate the same pine nuts, so it could be a body chemistry thing. Anyway, it’s Monday now (my 2nd day of bad tastes) so hopefully it’ll clear up on its own soon. I still have the packaging and will be returning them to Trader Joe’s and possibly alerting the FDA.

I finally managed to google and found this – what a relief, unfortunately I am not in the States or indeed anywhere near and there would be absolutely no point in me taking the packet back to the ‘Produkti’ that I bought them from.

    This post about pine nuts was just what I was looking for! I was eating an apple at school today and it was weird how there was a bitter taste at the back of my throat after each bite… but I teach six year-olds so I thought it might be possible that they’d gotten their jam hands all over it and that was what was causing the bitterness. Same thing happened at dinner, though. I had some friends over and I’d cooked lamb which tasted pretty good on first bite, but a couple of minutes later the bitterness would hit again. I asked my friends if the lamb tasted funny but they said no! So I did what many others before me have done and consulted the almighty internet (googled “bitter taste in mouth”, to be precise!!!).
    I bought a bag of pine nuts a few days ago, meaning to make pesto. Never got around to it though – have just been eating two to three handfuls a day for the past three days instead. No noticeable bitterness, until today. It’s not completely unbearable though. Just tastes like chemical… like someone else mentioned, it’s a little bit like tasting perfume that you’ve accidentally sprayed into your face?!
    I’m in Australia, bought my pine nuts from Colonial Fresh Markets (imported from China). Am hoping the bitterness will go away soon… this is only the first day!

    For years I’ve made pesto with pine nuts and eaten spinach salads with toasted pine nuts. I was buying the expensive Italian (at least that’s what the jar said) ones from my local grocery store here in San Jose, and I never had a problem. I’ve also used the Mexican ones with no bad effects, but they’re smaller, and I prefer the larger nuts. Then, when I was in Trader Joe’s last week, I saw they had them in large bags much cheaper, so I bought those and put them, toasted, in a salad. I also snacked on some raw while making dinner. Two days later I had this horrible bitter taste in my mouth. I ate a zucchini omlette and it tasted awful. So did my green tea, and the shrimp salad I had for lunch. I thought it might have been the zucchini or the celery in the salad – celery sometimes has a bitter after-taste like that. But the same thing happened when I ate a hard-boiled egg. Everything I’ve eaten since the first bad experience tastes awful! This is the fourth day after eating pine nuts, and it hasn’t gone away yet.

    When I got home from shopping, I took the nuts out of the bag and put them in a plastic container to store in the freezer, as I always do. They didn’t get rancid in my home, and they didn’t taste rancid when I ate them. I’m suspicious that it’s not rancidity but rather some kind of chemical treatment that’s causing this.

    The bitter taste is extremely unpleasant, but it’s good to know it’s not a symptom of some terrible disease, and that it will pass.

    I’m contacting Trader Joe’s even though I no longer have the package or my receipt.
    I think they need to know every time this happens. I won’t buy them there again, but I might try the ones I was using before. I really do like them in a salad.

    I think you’re right, Suzanne. I can’t believe that so many of us have rancid pine nuts. They do go bad quickly, but you can usually tell from the taste and smell.

    Phew, it’s not liver disease!! I’ve eaten pine nuts previously but have never experienced this bitter aftertaste until now. I bought the culprits from Trader Joe’s(it is such a great store though) after months of them being out of stock – must have been the source investigation etc mentioned somewhere in this thread, motivated by concerned pine nut lovers suffering from bitter aftertastes. I checked before consuming them and I didn’t think they were rancid at all. I tried roasting them and have to admit that I may have burnt quite a handful. Perhaps the chemistry of burnt pine nuts could have added to this bitterness mystery…?

    My husband and I received a big bag of pine nuts from our father in law a few days ago. We felt spoiled. They were from Costco in Washington. We indulged, probably had 3 large handfuls each along with adding them to our salad. Both my husband and I woke up yesterday with this nasty, bitter, back of the mouth, yucky taste. I can describe it as bitter and like a chemical. My husband says metallic. Definitely we notice it while we eat or drink. I just tried to eat a squash and it was disgusting, and I love squash. Coffee is nasty and I love coffee. How weird.

    Greetings from the mid-atlantic east coast, where a recent pesto experiment turned into a mysterious bitterness in my mouth (but no one else’s). I finally “googled” the problem and found this — ran over to my bag of pine nuts from Sam’s Club — sure enough, product of China! The brand is “Amport Foods” from Minneapolis, MN.
    I’m glad to hear I’m not alone with this strange sensation…
    I wonder if I should throw out the pesto I made, or give it out with a warning label!
    The squirrels will get the rest of the nuts — I wonder if they will have any trouble — I might have to check the squirrel blogs.

    Oh my gosh. Thank you SO much!! I wonder if you ever in a million years thought you’d get so many responses to this posting, but it appears that the pine nut affliction is pretty common. I’ve been suffering with the bitter/annoying taste symptoms for at least a couple days now, and I’m so glad I found your site from my Google search of “symptoms bitter taste”. I recently made a wonderful pasta dish, which included pine nuts (bought from a bin at Whole Foods in Raleigh, NC), and enjoyed the leftovers as much as the original meal. However, I had the bitter taste almost immediately, and it will not go away, despite the peanuts, baked Lays sour cream and onion chips, chicken vindaloo, wine, dark chocolate, and every other thing I can think to put in my mouth to get rid of the awful taste. Oh well. At least I now know the culprit! I’m not sure of the source of the pine nuts I purchased, but I’ll make sure I do know next time! Thanks again!!

    I treated myself to roasted “pinon” (pine nuts) being sold by a little old woman on the Santa Fe Plaza near the artists at the Governor’s Palace. Ate a few on my train trip back to the midwest. Have had the bitter taste for the 2 days since then. I love pine nuts, have purchased and eaten them for years, and have never had this problem before. I am guessing the pine nuts she was selling were old. Probably doesn’t matter where they have been purchased. After reading many of these comments, I am hoping the bad taste will go away soon……and I am throwing away the rest of that tiny packet of roasted “pinon”.

    OMG! Thank you for posting this – now I know the little culprit in my refrigerator are those damned TRADER JOE’S PINE NUTS! I had never experienced this before with pine nuts, but now I will always look for the country of origin before purchasing a bag.

    I was worried – I’m not ready to be bitter… I’m not even 30 yet!

    I purchased a large bag of pine nuts from Costco – bag says made in China. A day after eating a huge portion of them, EVERYTHING taste bitter, including candy corn lol! Please tell me this will go away! But then again, it would be nice to loose a little weight, as I don’t feel like eating anything right now!

    We too are enduring this bitterness, but only 5 of the 7 of us that ate them were affected. And lucky me has had the aftertaste the longest ( day 6 and counting). So I guess it affects everyone differently. My sister purchased them from Wal-mart, They are HOMA brand….. product of China.

    After reading everyone’s comments I am a little bit angry! I bought my pine nuts from Trader Joes’s in Nevada the weekend of Oct 4th. By reading everyone’s comments this has happened with pine nuts bought from there for months! Why are we not warned about this? I will never eat a pine nut again and I am only on day 3 of the gross taste in my mouth. I was relieved that this was the problem. It seems that no one has come up with anything that helps though. I have been chewing the mint flavor “5” gum and it does relieve the taste until I eat or drink again!

    Monday–ate a lebanese pizza LOADED with pine nuts
    Tuesday–horrible bitter taste, back of mouth
    Wednesday at 2:30–bitterness is still there.
    So just saying all the same things–Thank goodness it’s not a brain tumor–or pregnancy (which I read that people have bitterness, too, but I’d be too early)

    I am glad that I found this website, it helps alleviate some of my concerns about my tastes buds. Same thing as stated above, I made a huge batch of pesto the other night, everything taste great at the time. However, my next few days (still counting) nothing tasted correct. It made me think of what a horrible experience it would be for a foodie like myself to loose my taste buds for some reason. I hope it passes soon. Thanks for the info!

    Thank you!! I thought I maybe had a brain tumor or something. I ate a pre-made pesto pasta salad from Sumo Salad in Australia for lunch on Wednesday so not sure where the nuts are from or how fresh but the salad tasted great. By Saturday morning everything tasted awful – even my butter chicken leftovers, which the night before had been fantastic! I threw it out thinking it was that. That evening I had a glass of champagne and it was bitter so I thought it had gone off and threw the bottle too. Wasnt until Sunday that I realised it was not the food but me… I’m on day 4 now and its as bad as ever but thanks to this site I know whats going on. I have tried the V8 tomato juice but it tastes weird and hasnt helped. Might try the remedy of drinking ginger in water every 15 minutes, for 3 times (yuk) and see if that helps. I’ll try anything at this stage 🙁

    Well Nicole, thanks for solving the mystery!!!
    We live in Israel and I noticed the pine nuts my hubby bought last week at the open air market were smaller and differently shaped than the packaged ones I usually buy in the supermarket. I only ate a few…. (they didn’t taste as yummy either)
    A couple days later I noticed that my soup was bitter (the celery?), chocolate chip cookies were bitter (burnt?) etc… the next morning I finally figured out it was ME!
    OK– my question is, is something going on in the liver of pine mouth victims? I wonder if bilirubin is elevated? has anyone done a blood test? Would a “liver flush” help the situation? Perhaps colonhydrotherapy would help….. I’ll wait and see if it goes away soon before I get too radical! Hang in there and beware of Chinese Pine nuts!

    Michelle, as you can read in all the blogs above we’re all victims of the PINE NUTS syndrome therefore the only thing you can do is not to buy Chinese nuts and be patient for the next 5-6 days and the bitter taste will go away.

    Woohoo! I’m not insane. Everything I eat or drink tastes bitter, metallic, burnt, ashy, etc. ever since eating out with my family at Bootleggers, the other night. Thought it was bad yeast from their bread. Tried gargling for hours with salt water — as salt kills yeast. No change. Problem 3 days later is even getting worse. Can’t stomach ANYTHING, except some very sweet Mango frozen yoghurt (only thing I’ve enjoyed in the last 4 days — and I’m typically not a frozen yoghurt fan; never liked mangos, either; so, yes — sweet stuff does neutralize the taste temporarily. The culprit??? after reading your threads, it must be the handfuls of pine nuts I ate the day before going to out to eat (Bootleggers, you’re off the hook!). I’m not a big pine nut fan, but my wife bought a packet from Trader Joe’s in Las Vegas, NV — Melissa’s Pine Nuts and yes, PRODUCT OF CHINA! My father is visiting from Indiana — he ate the pine nuts, too, and is experiencing the same awful sensation, but was too afraid to ask me about it, until I finally asked him. Haven’t heard any remedies except time and sweets. Is that it? Personally, I think the Chinese are using us as test cases to validate a new weight-loss chemical that works by making everything taste bad. Anyone notified Dept of Agriculture? Concerned there should be a nation-wide recall of Chinese Pine Nuts.

    WOW! I don’t have as severe metallic/bitter taste as others, but it’s definitely there. It took 2 days to show up—not pleasant at all! I can’t wait for it to be gone! My husband only had a couple of the pine nuts (not a fan of the couscous I made) and he doesn’t have a problem. I ate what I cooked and bleck!! No more pine nuts for me–I like to taste what I eat.

    correction to my previous post — Pine Nuts I ate (Melissa’s Pine Nuts) — product of China but not purchased at Trader Joes. They were purchased at Albertson’s in Las Vegas, NV. And by the way, the Trader Joes rep said they no longer carry ANY products produced in China. But to add to the confusion — my sister recently had Pine Nuts produced “in Russia or Korea” and got the same horrific taste condition. As for me, the recommendation to eat very hot & spicey foods really helped. Condition has improved. Believe I’m on Day 6 and the bad taste has noticeably dissipated.

    I have been eating excessive amounts of pine nuts for days. And have been experiencing the metallic taste sensation. That, however, is nothing compaired to the discomfort in my neck. I have had severe neck ache/stiffness. Has any one else experienced this syptom after eating pine nuts? I am just concerned that it is not related to the pine nuts, in which case I should have it checked out. I haven’t done any unusual exercise or strenuous activity that could have caused the neck problem. It seemed to come out of nowhere at about the same time as the metallic taste problem. I will miss you beloved pine nuts!!

    Thank you a bunch. I bought a big bag of pine nuts to make pesto for the holidays. Stored in my freezer I have taken the bag out a few times for a little protein snack. For about 2days now it seemed like the nasty allergy drain was in the back of my throat, however mouthwash made it worse and all food irritated it. Not normal! With swine flu etc I have been freaking out. I’m a new mom….a bit neurotic! I have also had a bit of a headache that has been lingering with it as well. Instantly, after googling bitter taste in my throat, it said Pine nuts…i don’t eat these often at all so it makes total sense…

    Thank you!!

    I am on the 4th day of this reaction to pine nuts from China bought at Costco.
    I did have a neck pain for first 3 days. Now from the bitterness in my mouth, the reaction moved in to having sensation that inside of my mouth is burned, dry, very sensitive to hot foods, still, any food taste is revolting.
    I emailed a report to FDA , and emailed Costco. I found information that Costco is aware of the problem, I wonder why pine nuts are still on their shelves.
    btw, I always keep nuts cold or in a freezer.

    I recently ate a bag of pine nuts from Trader Joes and I am feeling the exact same thing. It is annoying but after reading this, I am positive it is what I have sa well. No I will not stop eating the little suckers, I love them too. But I will no longer purchase them on sale from Trader Joe’s, I will only get them from nicer stores and follow the recommendation to only purchase the Italian variety. Thanks for the information and have a good one.

    Hi to all the unfortunate.

    I also have this rank taste in the back of my mouth every time I eat. I had a few handfulls of Morrisons own brand pine nuts, although it says these are packaged in the UK the after ringing thier customer services they won’t disclose where it get’s the pine nuts from.
    I think it would be an for us all to put down what stores we bought our pine nuts from so that less and less of us have to go through this again.

    Crazy, how many people replied to this blog post with the same experience. Add me as another. I just had pine nuts at a friend’s dinner party and have had this bitter metallic taste in my mouth since.

    Wednesday I opened a refrigerated sealed bag of Costco Kirkland Brand Chinese Pine nuts to make Caesar salad. Thursday, I missed lunch and took an apple and small cup of pine nuts to eat in the car. Friday woke up to food tasting bitter. I threw out a loaf of Zucchini bread I had thawed thinking that was the culprit. Everything I ate all weekend did the same thing. Sunday night I found this helpful blog. Today, I am taking the package back to Costco.

    Had a few handfuls of Pine nuts from Trader Joe’s a few days ago and now everything has a bitter after taste. This sucks!
    The wierd thing is that I have been eating pine nuts my whole life and never had this problem before.
    I think Trader Joe’s needs to find a new supplier or at least put a warning up by the little culprit nuts.
    Now my main concern is are they treating these nuts with some pesticide or chemical that has this effect?

  251. Donna in Oregon

    Do not through the pine nuts in the garbage. Take them back to the store, even if you do not have a receipt or get your money back. They need to know. I called Costco headquarters and the helpful man said had not heard of this, but that if a lot of people returned the product, it would be noticed. If you no longer have the product, call the store manager and/or the company headquarters. This is a large and widespread problem. Call anything goes talk shows, Public Citizen; be creative.

    Thankyou thankyou thankyou !!!! …. like many others who have replied, I found this website while nervously googling my symptoms. I was about to go see the doctor about this later today. But now I know exactly what it is… I recently ‘pigged out’ on pine nuts in a delicious new pasta recipe I discovered … last week we ate it 3 times , plus I would munch a few while roasting them in the pan prior to mixing into the pasta – Its been a week now and that bitter taste is STILL there all the time after anything I eat or drink! … UGH!! – I thought I was going nuts (ha ha) …. by the way I am in New Zealand, got mine from a supermarket somewhere – so its a worldwide thing.

    Just read my last post and am embarrassed by misspelling throw.
    To the point; for curious, afflicted people: On day four of the bitter taste, I drank a large glass of strong ginger tea, made from fresh ginger root with some honey and lemon. After I drank it, my symptoms were nearly gone and have remained so. Today would have been a week and my taste seems to be close to normal. It could have just been a coincidence, but 10 minutes earlier, I had tried to eat a couple of different foods and it was bad. Ginger is known for having a lot of healing properties. I am drinking some now. Hot or chilled tea works for me. Tastes good too!

    I bought pine nuts made in China from Von’s a few days before Thanksgiving. I wanted to use them in a salad. While I was toasting them the day before Thanksgiving (Wednesday), I snacked on a handful. Friday, the day after Thanksgiving, I a headache all day ( I didn’t consume any alcohol) and noticed a bitter taste in my mouth every time I ate something. Nobody else has complained of any symptoms after eating the salad. I consumed more pine nuts than anyone else, so I am sure my symptoms are due to the pine nuts. Thank you for all the posts and information. At least I know I do not have a serious illness.

    I woke up this morning and went down to the kitchen for breakfast. My daughter had taken the leftover mashed potatoes from Thanksgiving for a perogie recipe she made the night before. I complained that she drastically over-salted them since it left a horrible taste in my mouth. Then I ate something else and experienced the same disturbing taste which has lasted the whole day. I just jumped on the computer and found this website and low and behold I put pine nuts in the broccoli dish I also made for Thanksgiving. I use pine nuts all the time and have never had any problems like this before. My pine nuts came from Trader Joe’s. I so relieved to find it’s nothing serious however, I hope this doesn’t last very long. It’s an awful thing. By the way, I always keep my pine nuts in the refrigerator.

  263. Loathing Pine Nuts

    Ahhhh! The gnarly bitter taste in my mouth has been driving me nuts. I plugged my sypmtom into WebMD, which indicated I may have epilepsy, but I know I don’t. I ate pine nuts two nights ago, and now everytime I eat something, it tastes like I’m chewing on aspirin. At first, I thought it was my face cream or hand lotion so I showered and did not put on any creams, but the nastiness persisted. Hoping it goes away soon, and I will NOT be consuming pine nuts anytime in the future.

    I am usually pretty good at figuring this stuff out but I was so glad to find this information. It sounds like the exact diagnosis 🙂 especially for us “internet-obsessed” researchers … I always sprinkle nuts in my salads and try to use just a minimal amount – great healthy reasons – but high in fats, especially the pine nuts! But the other night I just couldn’t resist adding much more than I usually do AND tossed a few back in some small handfuls of nuts while preparing the salad. That was just a few nights ago, and I don’t usually eat nearly that amount of pine nuts (since they are a staple in my house – and I will start putting them in the freezer too as another reader commented) … but I can’t wait for this taste to dissipate 🙂 Thanks to this website and its readers/commentaries!

    I strongly suggest trying tea made from fresh ginger root as an antidote. It worked for me, but it may have just been the timing on day 4. Slice a big piece of ginger root as thin as you can. Bring to low boil in a quart or two of water. Immediately turn down to simmer for about 20 minutes. This will be a concentrate. Add honey and lemon to taste and dilute with water to taste. Drink hot or cold. Very tasty and good for colds and flu as well as the pine nut menace. I would like to know if this works for others. I am not going to experiment on myself by eating pine-nuts again.

    Also, please tell your pine nut retailer about this problem. They won’t believe it unless they hear from a lot of people.

    10:27 am  Dec 6th, 2009
  266. Karen

    Donna — The ginger-cure worked for me as well. We often make a big jar of ginger syrup from fresh ginger root and keep it in the fridge. We mix it with seltzer or various fruit juices. Drinking this greatly diminished the pine-mouth for me.

    Instead of swearing off pine nuts althogether, avoid Asian (or Korean) pine nuts. Look for European pine nuts from the stone pine. More expensive, and harder to find, but much tastier and does not have this nasty effect!

    I am sprinkling some ground ginger in my green tea to see if that works… I am on day 4-5 and it is making me nuts (no pun intended) … I had some tomato sauce last night but a very small amount, I will see if more of that helps too… thx for all the advice out there.

    I ran into the same bitter taste issue two days ago. Same symptoms as other posters mentioned, and it was driving me nuts, too…so to speak. 😉 Just had an “ah-ha” moment as read this article. A few nights ago I made a homemade pizza with Hannaford store-brand pesto sauce (essentially pine nuts mashed with basil). So my best guess is that besides eating them plain, these ‘bad nuts’ have also found their way into other pine nut based products.

    I am in russia and yesterday afternoon things started tasting a little off. This morning it was terrable and now at lunch it is horrable. Started getting worried and did a search. I thought it was almonds, but i also ate some russian pine nuts. I hope this goes away soon. But then again i dont want to eat. So maybe i can use this to help cut down on eating;-) thanks for posting this, it saved me a lot of worry.

    So happy I found your experience on line…I like you, thought something was horribly wrong with me until my husband said that he was experiencing the same disgusting taste in his mouth especially after eating. We thought it was the new coffee we were drinking so we went back to our old brand. I had my daughter google our symptoms and she found your article. Low and behold a few days ago we had eaten a pasta dish I had prepared and added pine nuts as a garnish. I have no idea where they came from as I threw the package away but I intend to go back to the market that I purchased them from to find out. Wow… this is really inconvenient since it’s very close to Christmas and all the wonderful food and treats taste like yuck…anyone know a way to get rid of this taste other than time? Thanks

    12:09 am  Dec 10th, 2009

    Hi Carrie, there are 2 different remedies which people seem to have had success with. First is to drink tomato juice, like V8 juice or similar. The tomatoes seem to neutralise the taste buds. I tried this and it didnt seem to work straight away but the following day the taste was about 70-80% less and the following day it was almost gone altogether.
    Other remedy which seems to work particularly well with many people is to get fresh ginger and grate into water. Not so great tasting apparently but you could add sugar or honey to it to sweeten. This is supposed to work great, plus its really healthy for you too. If nothing works the taste seems to go away between 8-12 days so you should be ok for xmas day feasting!! Good luck 🙂

  273. Diane in NJ

    I am still amazed at this revelation, let alone the cause…. I would have never guessed had I not done the research. As I was approaching the full week point, I was getting concerned that it wouldn’t go away, but then read other accounts of almost two weeks. I also decided to eat a lot of tomatos, tomato sauce, and the ginger in my tea and can finally say at the 7th day I believe it is fully gone. Today is the 7th day and I haven’t eaten yet this morning, but I am enjoying my morning coffee 🙂 Yes, Carrie, you should be fine by xmas but I think the tomato sauce is a strong cure. Good luck! 🙂

    Wow, this is so relieving. After more than a week I started worrying that this was not going to go away – 10 days after eating (organic) pine nuts, food still tastes terrible. The hilarious part is that I also noticed it when I opened a new package of ritz crackers and I also shrugged it off because they had been in the cupboard for months. Anyway, I hope this goes away soon!

    I will keep commenting because I am still so amazed at this phenomenon – I really thought it wouldn’t go away but finally at the week mark it was gone, but I also up’d my tomato intake 🙂 Wow, we live and learn … Happy Holidays!

    It’s reassuring to know that this will eventually go away. My batch was from Food Emporium in New York CIty, sold by a distributor in NJ. I thought I remembered vaguely that they were from China, but threw away the container before I could check. Interestingly, the ones I usually purchase from Whole Foods never caused this, but perhaps that’s because I always took them home and put them directly in the freezer and only took the bag out for a minute when I needed some for a recipe.

    One experiment that helped me this morning, but didn’t make it go away completely, was brushing my tongue vigorously with an electric toothbrush for about a minute, just on my tongue alone. After I brushed and rinsed completely, I did a test and ate a handful unsalted pretzels right after, and they tasted much better than they did before, with bitterness only on the back of my tongue (where I couldn’t reach with the toothbrush without gagging). Not sure if this will help anyone else, but it helped me, or at least lessened the bitterness.

    I sure hope some scientists out there figure out a remedy for this. I can’t imagine that would be too difficult…

    I have been over the pine nuts thing for months now, but it continues to amaze me how many people post on this site! Obviously this isn’t an “unusual” phenomenon!

    Robert P.: salt neutralizes bitterness, so the pretzels may have helped with your taste sensation. I know I tried that when I was at my worst, but it always wore off.

    It seems many people report either tomato products (juice or raw) and ginger, besides salt as helping get the awful taste out.

    I have been having this problem for a few days now. Everything I eat tastes bitter…bananas, orange juice, tea, even sugar. I can’t enjoy my food because everything tastes so bad. So I googled it and first read about a lot of medical conditions that have a bitter mouth symptom, which started to worry me for a second, but since I didn’t have any of the other symptoms, I looked at another site which mentioned pinenuts. Well I made a batch of pesto a few nights ago, with lots of pinenuts in it, so that must be the cause. It has happened to me once before, but I’m glad I know the reason now. I bought my pinenuts at Trader Joes also.

    Thanks for the help in figuring this out! I’ve had a bitter taste in my mouth after every meal for the last few days, but it wasn’t until I found your blog that I made a connection to the pesto I made with pine nuts I bought from Trader Joe’s in Santa Monica, CA.

    Thanks for relieving all my worries, exact same thing happened to me after eating pine nuts from Trader Joe’s. It took me 2 seconds to google and find this story and laugh hysterically from relieve. I still love Trader Joe’s, and will continue shopping there, but probably no more pine nuts from there.

    I am very glad I found this info. about pine nuts on the website. Thank you all for writing in about this. I got a bad bitter taste in the back of my mouth starting last night and really am experiencing it today. And what do you know? I had pine nuts from Trader Joe’s a few days ago…the first time in a long time. I think this is the cause as well. Won’t be eating those again. Thanks.

    I’ve had a weird, bitter taste in my mouth for about 3 days. I bought some pine nuts (from China) at the store the other day and have been snacking on them. The bitter taste is on the roof of the back of my throat/mouth. Very strange. The nuts are gone, I hope the symptoms go away soon so I can enjoy the Christmas sweets.
    My son also ate some, but I haven’t had a chance to ask him if he has the same symptoms.

    After having the same experience and doing some research, I tried Ginger! And so far it’s working! After two days of bitter tastes and not being able to eat anything sweet or starchy, I tried concentrated crystallized ginger! It appears to zing your tastebuds back into action and I can eat normal food again without the bad taste. Will have to see how long it lasts.

    Amazing. My son who is an amazing cook whipped up cornish hen with pine nut/brussle sprout stuffing for dinner a few days ago. He was munching on the pine nuts as he cooked. The next day, he complained about everything tasting bitter. Mostly when he eats meat or anything that’s been baked or grilled. Fruit is okay. It’s been 3 days and he decided to go to the doctor, as it was worrying him, and also torturing him! I decided to do a quick Google and found this pine nut thread. We’ll try the ginger and see what happens. Thanks for getting this started.

    Thanks for sharing, everyone. My daughter and I are having the same problem. I got my pine nuts at Traders Joe’s around December 23rd or 24th. I made cookies on that day, and had several. The bitter taste started December 26th and still hasn’t gone away. It’s really starting to wear me down!

    Since last week, everything I eat has a bitter taste. Especially sweet things like cookies. My husband Googled “bitter taste in mouth, ” because we were concerned something was seriously wrong with me. This site came up, among others, about the pine nut issue. I, too, took a package of Trader Joe’s pine nuts out of the freezer and used them in salad last week and for Christmas dinner. I ate a few hands full as they are so good, but then I started noticing this horrible taste in everything I ate. The package says they are from Korea, Russia or Vietnam. I’m very unconfortable with this issue, as it cannot be good to digest something that can change your taste buds for radically. Think I will send them off to the FDA for testing. Also, will try some of the remedies. Thanks for posting all this info everyone.

    Here’s an update: I called the FDA, and spoke with someone this morning. I gave her all the information about when and where I purchased the pine nuts, but didn’t have the packaging any longer. She said they can’t do much without the specific lot information on the nuts. I asked if they had any other complaints (in Northern CA) and she said no. This is just fyi.

    I am so happy I found this website because I was wondering what was wrong with me. I had pine nuts at Christmas and I never eat them. I started having a weird taste and I was thinking the water must be contaminated or something. So I started to google my issue and found this website.Oh and Yes my pine nuts are from China so they are now in the garbage can.!!!It has been day 4 and it is still bothering me. It is so weird how everything I eat has a weird taste! I hope it get better soon.

    PLEASE DO NOT THROW THE PINE NUTS AWAY. TAKE THEM BACK TO PLACE OF PURCHASE EVEN IF YOU DO NOT HAVE A RECEIPT. THE MORE NUTS ARE RETURNED; THE GREATER OUR CHANCES OF BEING BELIEVED. Another website indicates that the Chinese pine nuts are from a different variety of pine tree than the non toxic expensive nut.

    Thank you for posting this! I had the exact same thing happen to me and worried the past two days that I might’ve had a brain tumor! I bought mine from Costco and had them in the fridge since October, it is now january and I was just starting to munch on them (South beach diet and new year’s resolutions and all) – I had no idea of the connection, what a thing!

    Wow! I’m so glad I immediately happened upon your information. As I type, I am eating my lunch and it tastes as terrible as my breakfast did! I rarely eat pine nuts, but included them in a salad two days ago. I would never have suspected those as the problem, and am glad to know I just need to wait it out!

    This is too weird…we bought a small plastic tub of Pine Nuts at Trader Joe’s to use a few for a Thanksgiving dish and have been snacking on the remainder of the package for the last month or so. I never tied the off and on bitterness to this ( I thought it was my cold having the affect) until I decided to Google it today. Funny, I happened to look at the pack just before I tossed it last week….they were from China. Maybe i’ll dig it out and send it to the FDA.
    Does anyone have any clue, biologically, why this bitter taste occurs and why it persists, and whether it happens to everyone or just some people?

  297. Nancy in So Calif

    To the question asked about if this affects everyone who eats them, it seems not. Several posts said that olther members of a family had eaten the same dish and only some of them had this problem. FDA is not really sounding interested when you call them. The Poison Center never called or emailed me back. News outlets are not responding. Most people are not sick with this but I had diarhea the night I ingested them and body aches and malaise for several days. My friend called to say she had the bitterness I was experiencing (seems to happen 2-3 days after injestion)although none of the other symptoms. I wrote Trader Joes and they responded but are not removing them from their shelves…shame on them. We are being poisoned by these and no one seems to be doing anything.

    We have been buying pine nuts from Costco for several years and never had a problem. But last weekend we had pine nuts on pasta, and then I snacked on a bowl of pine nuts that had not been used in the pasta (the rest of the bag had been put back in the freezer). Two days later I ate some left over lamb chops that tasted terrible. Tonight we had lamb again, and it tasted terrible to me. My wife thought it was delicious. I also ate hamburgers from McDonald’s today that tasted metallic, just like the lamb. Meat (beef and lamb) seems to be the only thing affected. We had pork the other day, and I noticed no problem, but perhaps the flavor was masked by the other ingredients in the stir-fry.

    My husband and I ate the same pine nuts (from China) in a salad. Only I experienced the bad taste, he did not. Perhaps you can equate it to smelly urine when certain people eat asparagus (unfortunately, I’m one of them too). I think it may be an one of those occurrence that poses no health risks.

    My daughter joined us and another friend for lunch last Sunday. She lives 2.5 hrs away. My husband began complaining about the awful bitter taste the following Wednesday. When I talked to my daughter she was having the same problem. I nor the other guest had the taste. The search for an answer was on, and led me to this page tonight. I called my daughter to see if she had eaten any pine nuts. She said yes the ones in my fridge last Sunday my husband did too. I nor the guest ate them. They are from China! This has got to be the answer. I was trying to blame it on post nasal drip ha ha.

    Yup, my daughter and me are experiencing the same thing. Amazing! We had the pine nuts 8 days ago and are still having the bitter taste. They also were from China. Stater Bros. store brand. I will try the ginger. It is a relief to see other people with the same symptoms! Hope it goes away soon.

    Update: We were seven days into this when we tried the ginger. In my opinion it helped my husband and daughter. However my husband wasn’t sure i the pine nuts were the problem. So last night he ate a few more from a different source. This morning the bitter taste was back. Apparently the more you eat the worse the effect.

    The best way to solve the bitterness and bitter taste of pinenuts in your mouth is not to buy them or eat them. The best alternative is to buy All American from Nevada Pine Nuts at The Pine Nuts offered there are Organic Grown ALL Natural, Non-Processed and Fresh tasting with No Preservatives or additives that give the bitterness taste. Taste the difference for your shelf. We offer free shipping on most packages with the best price on the market.

    Keep buying ours and you will be happy! 😀 We do not get involved with chinese pinenuts much. We have not done test on chinese pinenuts. We do however know that in order for pinenuts to be Shelled and placed in bags for long periods of time many manufactures or providers/producers will add preservatives to the pinenuts which is one cause for there unfavored taste.

    Also understand that something can be certified Organic, but that doesn’t mean that the pinenuts are FRESH or better said, that you are buying fresh pinenuts. Some companies that import (or that don’t harvest their own pinenuts) sell old or out of season pinenuts whether they know it or not.

    Thanks for your comments Veronica!

    Ever since I was “smitten”, I’ve looked for a country of origin on the packaging. I’ve found mostly Chinese pine nuts. I did notice that at my local Fred Meyer, the bulk pine nuts now have a label with the country of origin on the bin. That’s never been there before. (that’s not where I bought my bad pine nuts) Nice to see the labeling coming to stores in the area.

    I have had a bitter metallic taste in my mouth for several days when I eat or drink, and I decided to google my symptoms. I am so glad this website exists as it has put my mind at rest. I too had pine nuts from Sainsbury’s in the North East of England. These were in a mixed bag of berries and nuts and they are from various countries. I will drink some tomato juice as that seems to be the only remedy I can find, otherwise I will just have to ride the storm til my taste buds are back to normal. Thanks for all these postings, I feel better now!!

    I experienced pine mouth after eating a handful of “Melissa’s” pine nuts purchased on the Boston Ma area. After three or four days, I’m feeling some relief since this morning. I’m still afraid that eating might trigger the bad taste. If I’m actually getting over the symptoms this quickly, I feel lucky in comparison to others who suffered for much longer.

    Just two days ago, I had pine nuts from a newly opened bag gotten from Trader Joes and I am suffering the same symptoms of bitter taste in my mouth. Per the packaging, it is a “Product of Korea, Russia, or Vietnam”.

    Now, one of the other reasons that I wanted to write is the author’s mention of headache. I am also a migraine sufferer and I typically get visual auras of light sensitivity or vertigo and high olfactory sensitivity — I can’t go near candle shops, walk by open Bed, Bath, Beyond stores without holding by breath, etc. Interestingly, as the bitter taste became prevalent, so too did a migraine. Even more so, the typical remedies to reduce it if I catch it early enough didn’t help and it has persisted with the bitter taste.

    Given the hypersensitivity of input that migraine sufferers face and the similar hypersensitivity to bitterness from these pine nuts, I’m wondering if anyone else has had exepriences that might indicate a connection. I should mention that I’ve inhaled handfuls of pine nuts from other sources (like Costco) and this is the first time I’ve had a reaction.

    ok. i am sooo frustrated! i ate pine nuts (only a small handfull) 3 days ago and this bitter tatse is almost unbearable. eating anything is horrible! i found your post after googling bitter taste in mouth. thank you GOD for google. i have 2 questions… why are these even on the market if there is even the potential of this happening and has anyone come up with a cure? please someone tell me there’s a cure. it’s been 3 days and i can’t stand this anymore.

    Jim D, there are 2 different remedies which people seem to have had success with. First is to drink tomato juice, like V8 juice or similar. The tomatoes seem to neutralise the taste buds. I tried this and it didnt seem to work straight away but the following day the taste was about 70-80% less and the following day it was almost gone altogether.
    Other remedy which seems to work particularly well with many people is to get fresh ginger and grate into water. Not so great tasting apparently but you could add sugar or honey to it to sweeten. This is supposed to work great, plus its really healthy for you too. If nothing works the taste seems to go away between 8-12 days so you should be ok eventually. Good luck 🙂

    I tried the tomato juice at the end of day 3. It helped a little, but not much.
    the ginger tea was almost 2 days further in the process, but it took the taste away almost immediately and it stayed away. I am pasting the ginger tea recipe I published here a few weeks ago. I and most of my friends think ginger tea tastes great.

    Slice a big piece of ginger root as thin as you can. Bring to low boil in a quart or two of water. Immediately turn down to simmer for about 20 minutes. This will be a concentrate. Add honey and lemon to taste and dilute with water to taste. It is great hot or chilled.

    @Donna in Oregon
    Thanks for posting the tea recipe. What do you consider a big slice of ginger root? I’m guessing about 4″x2″ thin sliced. Can you give me a visual?

    5:06 pm  Jan 19th, 2010
  315. Donna in Oregon

    The tea recipe is flexible and forgiving. With a 4 inch piece, slice it as thinly as possible (quarter size). A food processor works great. Then, put it in about 6 cups of water. Bring to a slow boil and immediately turn it down to simmer. 20 or 30 minutes is good. If the ginger boils, it will not taste as good.Then you can strain the solids out. I add honey when tea is warm, but not hot. I use about 1/3 cup for this amount. It will be concentrated, so add some water and honey before drinking the tea.Get well soon.

    I have had a bitter taste in my mouth for the past couple of days and you guessed it I made some pesto with pine nuts. The brand of pine nuts is Ducks and the label says it is an imported product I’m guessing they are from China. I had no idea they could be such a problem! I can’t enjoy any food, it all tastes terrible. Hopefully it will go soon.

    As for cures, I just ate a handful of fresh Rosemary. It wasn’t pleasant, but the hideous ‘pinemouth’ tang has curtailed somewhat.
    I shall venture to invest in some ginger on the morrow.

    This is outrageous and so bizarre! Like everyone else I thought I had some other serious problem or another sinus infection except the taste in my mouth was different in that it had a metallic element. Yesterday as I sat down to have a veggie wrap with homemade pesto and it (like everything else I had eaten the last few days) tasted like crap, I had had it! I went straight to my computer and googled my symptoms. Low and behold, turns out, this is a mini epidemic! From Pine nuts! From Trader Joe’s! I love pesto and decided to make some with pine nuts I purchased from TJ’s, I found this site and many like it just as I was finishing my pesto filled wrap! UUuuugh. I guess I have to suffer for a few more days. Hope it ends soon. Im hungary!!!
    Also, as I finished the wrap I instantly got a stomach and headache for about an hour. HAdn’t happened before but, I had been re-exposing myself to the pine nuts everyday for the last three days…..

    I have worked with American Pine nuts for 14 years and this issue of Country of Origin and “pine nut mouth” made prompted me to look at US Trade data for pine nut imports. This is from our blog post today:
    2009 January – October (Top 10 countries – – 2009 October)
    Wholesale Value in USD 1/09 to 10/09):

    China $52,208,000.00

    Turkey $8,765,000.00

    Spain $700,000.00
    Pakistan $43,000.00
    Hong Kong 0
    Italy 0
    Brazil 0
    Canada 0
    Lebanon 0
    Portugal 0
    Switzerland(*) 0
    Some of these countries may seem odd, but they are on this list because it is based on historical export to the United States and those countries have historically been exporters. Russia, Korea, Viet Nam are not in the historical trade data, neither is Mexico

    i thought there was something wrong with me! and i just had dental work done last week and thought that could’ve been the reason. but after reading this article, i think it was either the pesto sauce my mom used for spaghetti or from a creole restaurant I ate at this week. i’m happy to know that it will eventually go away, but i’m sad to know that it could take a couple of weeks 🙁

    I wish I had time to take on this issue. Instead we are never going to eat pine nuts again. As I mentioned before my husband the skeptic tried pine nuts again after approx. ten days of PNM (pine nut mouth). He has had PNM for another ten days and nothing helps.

    Same EXACT thing happened to me. Mine were from Trader Joe’s, also. And the package says that they’re from Korea or Russia. I found another article online that describes the different types of pine nuts. Guess what kind are grown in Korea and Russia?!? That’s right, Chinese. Pisses me off – even at Trader Joe’s prices, it was $8 for an 8 oz bag!

    Just left my last post before reading through all of the others listed. Yes, the answer is GINGER!!! I don’t think you need fresh, though.

    It is amazing to read this blog. I ate a whole packet of pine nuts last week then blamed the bitter taste on my dentistry. This is a little quote on how to tell the difference between the pine nuts

    “There are distinguishing characteristics between the nuts, with the Italian stone pine variety being short and stubby while the Chinese white pine tends to be longer and thinner”

    ditto, ditto, ditto.
    Bizzarro bitter metallic taste in mouth.
    Ate Trader Joe’s pine nuts 2 days prior to symptoms.
    Thought it was something serious (Diabetes.. et al).
    Totally disruptive to appetite.
    Currently on day 4 (approx)
    From this site, I can’t help but think there is something new going on. All these people with all these similar symptoms in such a short amount of time. Were people complaining about this for the past 20 years or more, or is this really a recent phenom?
    Also, if this is a recent phenom, you better believe that this has a potential for another news worthy Chinese export problem like lead paint on baby toys.

    Ginger tea and candy helped for a few hours at a time. Over the week that I’ve had this (now very diminished) problem, I found that chocolate and peanut butter were pretty much OK. Can you say Reese’s diet? 🙂

    Seriously, I returned my opened bag of pine nuts to Trader Joe’s and they happily refunded my money. When I mentioned why I was returning them to the manager, he stated that he hadn’t heard anything like this before and would mention it to upper management. Since so many people have sited TJs as a source, if you haven’t returned the nuts just for your $8 back, it might be worthwhile to do it just to request that word be sent “up the chain” to regional management and attract some attention.

    When I previously called regional to discuss MSG — a topic many manufacturers will try and state is a problem only in so many people’s heads — TJs told me they try to avoid any product with added MSG. My point being that if enough awareness is raised and it is shown to be widely distributed amongst their customer base, they may be more cautious about the source in the future.

    Wow, thank you so much for this info. My bitter mouth started yesterday morning and has been terrible. I googled about the bitter bile taste at the back of my mouth after everything I eat and drink and it came up with a variety of things including liver problems which scared the hell out of me as I’m on Olistat. I was about to call the doctor in the morning to check sinises etc, until I stumbled on this site. I have some pine nuts that I bought from Sainsburys and I’ve had them for a couple of weeks. Sure enough I munched on half a dozen or so on Weds or Thurs so it took 2 or 3 days to start. I’m on day 2 of pine nut mouth at the moment

    Same experience with Trader Joe’s Korean pine nuts from a dinner two nights ago. Bleh! I brushed my tongue last night vigorously with an electric toothbrush, as far to the back as I could without gagging. Today the bitter taste is much reduced. Maybe the taste would have gotten better on its own, but brushing the tongue is probably a good idea, anyway. Those of you who get pine mouth might give this a try. Also, I complained to TJ via their web site. FDA, too. No response yet from either.

As someone posted earlier we have been eating pine nuts for years and never experienced this before. I am going to give my congressman a link to this thread. Also consider the folks who have not accessed this info. and have no clue.

    Had pine nuts in my pasta on Friday and again in leftovers Sunday. Bitter taste started Monday. So glad to find this chain. I’m off to try out the ginger tea recipe!

    So strange! I had hummus with pine nuts on Saturday night and the bitterness started on Monday I believe. I had very few pinenuts in the hummus and I have bought this brand before and didn’t have problems. How annoying. I am, however, excited to know that there is nothing wrong with me and it will go away. Now I don’t want to eat the hummus anymore! argghhhh and I love it!

    For the last four days, my husband and I have had a horrible taste in the back of our mouths. EVERYTHING that I’ve had to drink or to eat has been followed by a bizarre combination of bitterness, poison, and/or a chemical aftertaste. My tongue even feels “burned”.

    I googled the symptoms the other day and scared myself half to death. I began to suspect everything from the homemade cookies that I’d made that night to our cleaning products, to our coffee and our toothpaste. In a panic, I googled the symptoms again this morning and found your post. Two feelings; one, I’m so grateful to realize this sensation will be gone in the next week and two, I’m SHOCKED that I am leaving the 338th comment. This has affected so many people!

    Because of your blog I now know that the pine nuts that went into our pasta four nights ago are the culprit. I’m thankful that my two young sons weren’t that hungry that evening. My husband and I are still paying the price!

    PINE NUTS!! I searched and searched the web trying to figure out what was going on with me…PINE NUTS!…I just had them 2 days ago! I’m just glad I’m not dying. 😀

    I had bought some mixed nuts from Waitrose and ate a small handful after dinner for a couple of weeks. I had a terrible metallic taste in my mouth and googled it to find it was pine nuts. I stopped eating them 29th Dec 2009 and one month later it is just as bad! How long will this go on? My daughters partner also had this and stopped eating them and within 2 days the taste had disappeared.

    Thank you! I ate a whole bunch of pine nuts earlier this week. Two days ago (and about 2-3 days after the pine nuts), the same thing happened to me! I thought I was doomed for a throat cancer diagnosis or something, but then I googled metalic taste when eating and I found this page.
    So far the taste has persisted for 3 days, though this is day 4 and it is a bit better. How weird! No more pine nuts for me!

    I wish I had found this information before I ate a half bag of pine nuts! I actually came across this info when looking for nutritional information on pine nuts a while ago. I had cooked with pine nuts a week ago and was complaining to my boyfriend for several days about this metallic taste in the back of my mouth. I thought he had gotten me sick, but the only symptom was the chemical metallic taste I had for several days.

    Of course I just learned this today AFTER I ate several handfuls of pine nuts! I just checked my bag (purchased the other day from Walmart in Anch. Alaska) and it says that it was packaged in USA and contains pine nuts from China. At least now I will not be surprised when I get the nasty taste again. Oh yay for me. Grrrrrr.

    I have pine mouth now! My son and I were in the kitchen eating toasted pine nuts for at least 20 minutes. I toasted them for a recipe and we ate all of the left over pine nuts. He told me a couple days later that he had a bad taste in his mouth, however, I thought that maybe he was getting sick and made him take Airbourn. The next day a I made eggs for everyone in the family and when I took a bite I started telling everyone not to eat the eggs because they were bad. I tried to drink coffee to wash down the bad taste then noticed how bitter the coffee tasted. I has been a week now and we’re both still tasting a bitter nasty after taste. My 11 year old son came up with the great idea if you eat very fast then it is not so bad until you’re finished eating. It works for him and I have to say that I did try it but eating fast is not my thing. By the way, the spicier the food the worst for us. Thia curry is a not on out list for dinner this week. I need to lose 10lbs anyway and I guess this is a good time to work on my diet.

    Another victim. Pine nuts 4 days ago, bitter taste for the last 3. I am in New Zealand, and god only knows where the nuts came from, but it has been extremely hot and humid for the last week. There still doesnt appear to be any remedies (from what i’ve googled but there is a lot to read) but i have found the following from my own experience
    Really really really bad=
    processed cheese

    Not so bad=
    plain rice
    hot tea

    everything else somewhere in between. If anyone else has any suggestions please let me know. Heres hoping that it goes away soon

    I am now on day two of “pine nut mouth”, The nuts were purchased at Trader Joes, Scottsdale, AZ. I have had the syndrome before. This has not occured with store bought pesto, for some reason. Maybe it just depends on the quantity injested, for I did eat alot of them. I defintly will not be making home-made pesto with these, I will try it made with walnuts. I am determined to find a remedy. I would like to know exactly why this occurs? is it the pine oil which lingers in the bloodstream or is it that our tastebuds are temporarily altered by the pine oil in some way. Anyone know.
    I will let you all know about my remedy testing.

    PEOPLE: Keep complaining, and warning your friends. I told my neurologist about this in case someone brings the symptoms to her.

    I just found the article below on another website.
    “So perturbed by his symptoms was Roger Hyam, a botanist from Edinburgh, he thought he had jaundice or diabetes.
    He has since started a pine mouth website in the hope fellow botanists might be able to offer help or an explanation.
    Those who found out about pine mouth via the internet were the lucky ones.
    Others sought medical help and were sent for blood tests or liver scans, while some approached their dentist to see if mercury was leaking from their fillings.
    Home remedies recommended by sufferers include drinking liquid aloe vera and taking activated charcoal tablets (charcoal is often used as a detox in cases of drug overdose).
    So what’s actually happening here? And should we be worried?
    In reply to a group of pine mouth sufferers in Wales, the Food Standards Agency contacted doctors at the Brussels Poisons Centre, who have carried out tests on the pine nuts, but have been unable to identify any chemical differences between those that cause pine mouth and those that don’t.
    The good news is that no pesticide or heavy metal contamination has been found in the pine nuts. The puzzling news is that while some people get pine mouth, others don’t, even though they’ve eaten the same batch of nuts.
    ‘It doesn’t seem to be an allergic reaction, either,’ says John Collard, clinical director of charity Allergy UK.
    ‘It may be there is a chemical constituent in the nuts that causes the taste; possibly the oils in the nuts have gone rancid because of poor storage.
    ‘Just as caffeine increases some people’s heart rate more than others, some people may be susceptible to these oils, and some not.’
    But in the meantime, food retailers are not rushing to warn the public, despite shoppers at most of the major supermarkets claiming to have experienced the problem.

    Ok I think this is my 5th or 6th post so you can look back and read about our experience. I contacted the F.D.A and filed a complaint 1-29-2010 I called Penny Harris in the complaint department 404-253-1256 she was aware there is a problem and says there is an ongoing investigation. She asked me a list of questions of which one was did I have any of the product left for a sample. I did not. Then I contacted my local TV News WTOC Channel 11 Savannah GA. They did a story on it and interviewed a Dr. who said we have “Pine Nut Syndrome.” You can go to WTOC website and look at the video on the news page. My point is There needs to be more follow up by the FDA. I bet there are thousands of unnecessary tests done monthly because of this and who can afford that? In my opinion before social networking the magnitude of this reaction wasn’t taken seriously. I suggest everybody contact the FDA this is just plain wrong.

    I fell victim to pine mouth over the weekend. Thought it would be nice to put on salads. I thought I was going crazy. The first thing I ate was an apple. I kept swearing it was tampered with. My hubsand tasted it and said I was crazy and paranoid the apple tasted ok. We ended up having a big fight. I hate it when men dismiss you and say it was just all in your head. Thank godness for this website. I notice my husband ate some just yesterday. Mine did not kick in until 2 days later. Who is gonna be the crazy one now.

    I have laugh cried reading these posts for 2 reasons! 1. My bitter taste is not a symptom of some fatal illness and 2. I am not crazy. I made a batch of pesto on Saturday and shortly thereafter, I started having this really bitter taste in my mouth that was made worse with EVERYTHING I ate. I mean everything. I am still having this bitter taste but at least now I know why. I am so thankful for this post because it definitely is an eye opener and I am amazed at how many people have been through this experience. So much so that I feel it probably should be added to the label of pine nuts that it “may cause bitter after taste”. Indeed the FDA looking into this will be worth the hassle.

    I am so glad I found this post, I was beginning to think there was something seriously wrong with me. I love pine nuts and ate a bunch of them several days ago – they were from China. I normally get them at Costco and have never had a problem but my husband picked them up from Sam’s Club last week. They are going back. I hope this horrible taste goes away soon. It doesn’t bother me as long as I don’t eat!

    Thank you all for the post. I got up two days ago with the bitter taste at the back of the throat and wondered how this could have happened. After reading this post, I can defintely confirm: for the first time in many moons, I had a craving for “something different” and tatsted some pine nuts kept in the freezer. Funny thing is that it is not the regular brand we buy!
    I guess that it is a matter of time, is it not?
    Thanks again.

    Another victim of Pine Mouth. Got ours from Costco. Had some on a pasta meal. Hubby wasn’t effected. But, I toasted some the next day to store in the freezer and nibbled on them while they cooled. Sure enough, 2 days later the taste started. I now eat my meals quickly so the bitter taste only sets in once when I’m done. It wasn’t too bad after eating a salad with a dressing I made of apple cidar vinegar, evoo and mustand. I guess the sharp taste of the dressing tamed the after taste somewhat. I’m on day 3 and it makes me crazy to think I still have days to go before this goes away.
    Question though… does this mean we can never eat pine nuts again? Or just make sure they don’t come from China?
    Even as I type, they are adding pine nuts to a receipe on the food network. Eeks!!

    I stopped eating pine nuts on 29th December after googling metallic taste in mouth and 6 weeks later it is just as bad. Is there anything else it could be? In particular, bananas, porridge and tea taste bad. My husband says my breath smells garlic/oniony! I’m getting paranoid!

    10:13 am  Feb 14th, 2010
  361. Barb

    Chris, 6 weeks is a long time. Perhaps you should check with your doctor since everyone reports that it is usually gone after a week or 2. Tea brings it on for me as well and I cannot face the day without my cup of tea. Ugh!

    Another “wow” here. It seems like this problem has been like clockwork. Happens about every 6 weeks, and I’ve been trying like crazy to figure out what I’m doing or eating differently. For me, I woke up one morning with everything tasting bad – this started last fall, and I’ve been eating pine nuts for many years. The bad taste lasts for a week every time, goes away for 4-5 weeks and is back again. At one time I thought it was a pesticide issue because I eat a lot of veggies and nuts. This last time around, I didn’t have any pine nuts, but remembered I had a jar of pesto in the frig that I used. The bad taste is back again, and hopefully in a few more days will be gone. I’m a junky when it comes to eating nuts – pine, walnuts, pecans, almonds, etc. I think I’ll have to stop just to see if it’s really the problem.

    I’m very bothered by the fact that so many people have this issue, and that it takes sooooo long to get rid of – a whole week every time I get that bitter taste, but encouraging to know I’m not alone.

    Well – what can I say?! I went out for breakfast this morning and experienced the most disgusting taste in my mouth! I somehow knew it wasnt the food I was eating, as I could taste that too – but this taste, literally on the back of my tongue, was taking over the taste of the food. IIt was horrible! Later, eating again – this taste took over again. I was really worried that it was my palette or, that I’d inherited a loss of taste from my Dad and Grandmother! I decided to google it. And Here you all are – amazingly suffering the same symptoms. I do not have a headache, I do not have any other symptoms bu tthis taste – as well as being very bitter and metallic – is almost undescribable! It’s like someting you might clean the drains with! As soon as I saw Pine Nuts – I knew! I had bought some as a snack from Asda Walmart in Derby UK, and knew it must be that. Weird how sweet things do not taste so bad – but savoury is horrific. Thank you all so much for this reassurance – and I hope you’re all well now!

    OMG! This is the worst!!! I also purchased pine nuts at Whole Foods, put some in the salad I bought from there and once I ate it my toungue felt kinda strange, almost like it was numb. Well didn’t think anything of it. Sunday morning I woke up and I had the “Bitter taste on my tongue”. Glad to know it goes away but DANG!!!
    Oh also, I found that gargling with salt water helps a lot!!!

    This is my 2nd post. I was sick during the night. I contacted Trading Standards today re this whole situation. They advised me to take go back to Asda, which I did. Both are investigating and I have been advised to keep a few in case anyone contacts me and Asda have taken the pot back and will send off for checking. Will update with any news.
    Although I do get a bit of taste throughout the day – it’s only when I eat that it comes on really bad – and everything is rancid! Therefore, I feel it is to do with the saliva which is created to chew and break down food. Beyond that – it’s a TOTAL mystery!

    I ate pinenuts from Trader Joe”s two days ago. This morning I had a similar experience as others: I woke up and found that my morning coffee tasked bitter. After eating dinner, I started to think I was having a health problem and googled “bitter taste in mouth”. This is definitely concerning. From now on I’m only buying pinenuts from the US and Italy too- though they’re getting hard to find around Boston.

    This is my 2nd note on this horrible experience. I thought it would never go away but here I am on my 6th day and finally it is gone!!! Just thought i would note a list of things that helped me deal with the disgusting rubberband taste in my mouth..
    Lots of Lemon Water
    Rain #5 spearmint gum
    Leroux (peppermint schnaps)
    Hot Red and/or Green Chilli.
    Gargle with salt water helps also
    I tried the tomatoe Juice YUCK the rubberband taste got worse! The Ginger tea didn’t work for me either. Well good luck to you all who are still dealing with this just know it will go away……No more pine nuts for me that’s for sure I dont care where there from I’m done!!!

    This is sooo strange because my friend only introduced me to pine nuts recently and I loved them. In fact i sat and ate half a bag at my computer 2 days ago and today have had this vile taste in my mouth which is worse when i eat. In fact, it has even put me off my beloved red wine! So hope it goes away soon but glad to know it’s something temporary! The odd thing is that I described the taste originally as that of a bad walnut that you take a bite of by mistake. I absolutely convinced it was the pine nuts! Thank heaven for Google!

    I started with this ‘Pine Mouth’ on Tues and it has improved by today (Sat) but not gone completely. I barely ate for 2 1/2 days, but have now got an appetite back after being scared to eat because of disgusting taste! I did try eating raw ginger, (as I didnt have any of the candied) – Im not sure if it helped but certainly things are better than they have been. I have no news yet, re the source and Trading Standards who are apparently investigating.

    Hi Elaine from Derby! Seems I have a few more days to go then so bang goes the sunday roast which I will have to prepare for everyone else and then just look at! Maybe we should market pine nuts as the new wonder slimming pill! All I can actually eat that tastes relatively normal are clementines! But I have to say I would be interested to hear what the Food Standards Agency make of all this and will get in touch with them tomorrow. My pine nuts were produced in China and sold by Tesco Express and were certainly not out of date.

    For lunch, I sprinkled some (what I believe were raw) pine nuts into my salad that I prepared at Whole Foods Market in San Francisco (Fourth Street) on Thursday, February 18. Things started to taste bitter late afternoon the next day but it worsened the following morning. Whatever I ate was bitter tasting; I felt like I had swallowed medicine/aspirin in my mouth and the taste lingered. I feel a little nauseous after eating because the food tastes so bad to me. I sent an e-mail to Whole Foods about my suspicions.

    Well I am in day 4 now and the symptoms are starting to fade. Managed to eat and drink reasonably normally but the taste is still slightly there in the background. Yesterday I ate some ginger in preserve – sickly sweet but it seemed to help. I have been so irritated by this condition that I reported it to the FSA and Tesco today. Will report back on my findings. Will try and contact you too via Facebook Elaine – thanks.

    Ate some on Wednesday afternoon and by Thursday morning everything tasted bitter and poisonous, kind of like cough medicine. Bought mine at Whole Foods on Fairfax in L.A. Today is day six. Things seem to be improving. I say with fingers crossed. While trying to figure out what was going on in my mouth and with my tastebuds, I also found that Crest Pro-Health toothpaste has a lot of complaints relating to tastebud and mouth damage as well. Lucky me, I was used Crest Pro-Health toothpaste and ate pine nuts at the same time. I think both should be off the market.

    The best way to solve the bitterness and bitter taste of pinenuts in your mouth is not to buy them or eat them. The best alternative is to buy All American from Nevada Pine Nuts at The Pine Nuts offered there are Organic Grown ALL Natural, Non-Processed and Fresh tasting with No Preservatives or additives that give the bitterness taste. Taste the difference for your shelf. We offer free shipping on most packages with the best price on the market.

    I can’t thank you enough for solving my mystery. Like other people who have posted comments, I, too, thought it was a sign of some other more serious medical problem. I tried a new recipe a few days ago that called for pine nuts. I almost never eat pine nuts. I even toasted them myself with garlic salt. Although it was delicious going down, the soapy-bitter aftertaste started to plague me two days later. This is the third consecutive day with the bitter aftertaste. Nothing tastes good to me. Needless to say, all the left overs and the unused pine nuts have been thrown out. I’m happy to know this condition is temporary, and I can look forward to good-tasting food again one day. Pine nuts??? I can definitely live the rest of my life without them!

    I am currently having the same bitter-taste problem. I too have had pine nuts. I ate a bunch with dinner the other night. There was no bitter taste while I ate them, but about a day later I started getting the bitter taste. It has been three days and it seems to be getting a bit worse. I will be glad when this is over. The pine nuts are from China. My husband didn’t get the bitter taste. I wonder if there is some type of chemical being used somewhere in the process that certain people have more of a reaction to. If you look at the complaints, it seems to be more of a recent problem. This makes me think it has more to do with a chemical or enviromental issue than just outdated nuts. It really bothers me. Perhaps an email to the USDA? If the nuts have been contaminated, what other problems are they causing besides the bitter taste?

    Hello Cathy and others.

    I read on a different website that the chinese pine-nuts are from a completely different variety of pine tree and that people in China do not eat them the ways we do. I am sorry I did not note the URL. Also, a few years ago after reports from people like us, these nuts were tested by scientists in the west and no contamination was found.

    Wow and so bummed. I only a few nuts (5 – 10 which looked roasted in oil) at a Brazilian Steakhouse and I can’t shake this taste. I am so not eating them again. Not worth it. Bummed that I got to deal with this for weeks. yuk!

    Hello back and glad to say it is all over. I just wanted to note that after the bitter taste went away (6 days) I felt sick to my stomach the 7th day, not sure if it was the after effects of the Pine nut Poisioning but it was for like 2 days of stomach cramping. I didn’t see on any of the other blogs of any kind of stomach thing happening with anyone else but just FYI!!!! That’s what happended to me.It was strange because I couldn’t eat for days because of the bitter taste so I really didn’t have much in my stomach but fluids and when I could eat I was very cautious so who knows……..I hope you ALL get better soon I feel for you all this has never happened to me and I live in New Mexico where we pick our own pine nut which we call Pinon and never has this happened to me. I will never buy Pine nuts from Whole Foods or Trader Joes or any where they sell nuts made in China…..YUK!!!!!

    I do not think I will ever eat pine nuts again. I don’t know if mine were from China, but I don’t think I am brave enough to take the risk again. I am on day 7 and feel there is NO end in sight. I loved pine nuts and have eaten them often and never had a reaction. BUT, this is sever enough to make me swear off of them for good. I am so glad I found this blog, my husband and I were getting really worried.

    The consumers deserve to be warned about this horrible reaction. I have filed a case withe the FDA a month ago. They are well aware of the problem and assured me an investigation was in place. I was told they would not call me back but that I should call them back. I did today and was told they would return my call after they looked up the case. I did not receive a call. What good is the FDA if they don’t serve the people. Your tax dollars at work. Please call and report your concern.

    Happened to me, and I almost positive pine nuts are the cause for me, AND mine were also from Trader Joe’s. I normally am very happy shopping there, but no more TJ’s pine nuts for me…. my bitter taste is still going, I’m about 1 week into it 🙁

    I am currently experiencing this does any one know if there is a way to stop it. I read the post from a while back regarding tomato juice but that didn’t work any other suggestions???

  387. Elaine (Derby UK)

    I’m pretty sure that nothing has been able to stop it – but I followed someone’s suggestion of trying ginger (I didnt have the sweet stem ginger only a slither of fresh). I don’t know if this helped the recovery, but I was eating food again after 5 daysish. went completely after 6.

    The same thing has been going on with me for 4 days now and, wouldn’t you know it, the pine nuts are from Trader Joe’s. The weird thing is that other people who had then are not having the same reaction. But thanks to your post, at least I know I don’t have some weird disease!

    FINALLY! I have had the bitter taste for the last four days and could not figure it out!! I tracked it back and it all started the next day after grilled shrimp and pesto pasta…FILLED with pine nuts! Very odd sensation… but nice to know I do not have an incurable discease.

    Report it to the FDA !
    That’s what I did. It is horrible taste. Luckily I found this website.
    I never eat pine nuts. I did for two days, imported from China.
    Please report it to FDA !

    This happened to me right now! I eat a lot of nuts, including pine nuts. I store all my nuts in the refrigerator. I used some as a garnish in soup 2 days ago and the bitter taste started the next day. I thought it was the crackers I was eating, but the next day, everything I ate or drank had this taste. I thought something was wrong with me so I googled “bitter taste” and the very first article was about pine nuts. Bingo! I know I just had them! My husband had them, too, the same day and he had no reaction, which leads me to believe that it is a personal reaction and not something wrong with the nuts.
    Now I just wonder how long until this wears off…

    An update on the symptoms:things get worse the first 72 hours.
    Both me and my wife had nausea, vomiting, diarrhea after eating pine nuts,
    in addition to the horrible bitter taste unchanged.
    I was wondering if the toxin is getting worse in these pine nuts?
    Same brand as with others: 365 brand at organic section at Whole Foods,
    imported from China. Please insist at FDA. They eventually called back
    three times for more detalis, they seemed very interested.
    Please call FDA!

    When I took my “nuts” back to Costco, I included a letter and some comments from this page with the URL for it and another one I found.

    To Steven (above): How many pine nuts did you and your wife eat? I had about one cup over two days. There were none of the bonus symptoms you suffered. Some of us are more sensitive to whatever it is.

  395. Veronica

    One of the first things the FDA asked me was if I had some of the product. I did not have any. I filed a complaint with the Georgia Branch of FDA Penny Harris she gave me an address to write for results. We need to stay on top of this. Every case I’ve seen is from CHINA I filed back in January.

    last Sunday now (almost a week from today)! my dad and i sat down to a meal of creamy pesto over ravioli’s with of coarse ‘pine nuts’ our problem! we ate our meal and it was delicious! 🙂 but the next day i had breakfast and when i got finished i had the worst most bitter taste in the back of my mouth (like most) and it happened at lunch and dinner and it to this day is horrible it makes me wonder why I’m still eating food! and then my dad called me and said he did some research about the bitter taste (that he had too) and he read all the comments about those dumb pine nuts that i guess you could say poisoned our taste buds for the longest time therefore we FINALLY had an answer to that retched taste that is still bugging us and sticking in our mouths for as long as it has! 😀 the worst thing of all is that they were $39 a pound witch is highly over prised for nuts no matter where you get them from >:( one of the worst experiences I’ve had with food personally.

    Thank you! I developed an ‘aspiriny’ taste in my mouth yesterday and I’ve bee panicking a bit. I found your little blurb and remembered that I ate a tone of Korean pine nuts a few days ago. I never eat pine nuts, and I’ll think twice before I do so again. (I just finished some delicious aspirin yoghurt, which I imagine will be followed by an aspirin sandwich for lunch 🙁

    Thanks again.

    this is strange , same thing happened to me
    i’ ve had the bitter taste in my mouth for 3 days since i have been eating
    the pine nuts from trader’s joe(russian)
    so it might be important to have them checked
    who could do that?

    well, it’s reached New Zealand!
    I had pine nuts 2 days ago and now have the same old bitter horrible taste in my mouth after eating or drinking.
    Worse after sweet things.
    Water seems ok.
    It is so horrible I won’t eat pine nuts again. I love food. This is sheer hell 🙂
    Anyway, 2 days down….don’t know how many to go.
    I’ll check back to let you know

    I`m so glad I found this article…I thought I was going crazy. I had a salad with pine nuts 2 days ago and some pine nuts at lunch today and ever since, i`ve had a bitter/chemicalish taste in my mouth and throath. From my coffee to a glass of water, and the bloody mary i`ve just had. I just hope it will not take weeks before it disapear…It`s quite a gross taste.
    Thank you for the information,

    ok into day three now ans it seems, ever so slightly, to be getting better.
    I’m doing nothing special, just eating and drinking as normal.
    Still pretty yuggy though.

    Thank you all for this! My husband and I have been suffering from a bitter taste in our mouth for the past 3 days and we have started adding pine nuts to our salad last week. As doctor advised my husband to eat more nuts for health reasons. I bought the pine nuts from Cosco and will return it right away! Thanks again.

    CRAZY. I just made pesto with pine nuts( frozen by me..and TOASTED) from Trader Joe’s. I coulldn’t figure it out ! Thanks for posting this !. I’ll be glad when it passes – puts a damper on EVERYTHING I eat!

    Day 6, still there a tiny bit, seems especially first thing in the morning. It is definitely getting better though.

    OMG, I thought I was going crazy….thought maybe my medicine was fighting each other in the belly, but sure shooting I ate Pine Nuts two days ago. This started yesterday morning with my coffee and cracker. Today is day 2 and it is still bad. I will NEVER eat pine nuts again. Never had such a bad taste and I don’t want it ever again.

    10:12 am  Mar 18th, 2010
  407. Viki

    wait – can we never eat pine nuts again??? that bitterness thing subsided after a couple of days and so I’m wondering if people who experienced this had pine nuts from Italy and all went ok. ALSO the pesto I made I ate again the other night before I figured this out and it did not re-start the bitterness – so It was either the straight up eating of toasted ones or a lone bad one. I reported it to the FDA and they are definitely trying to figure it out.

    10:38 am  Mar 18th, 2010
  408. Denise

    I have had this bitter taste almost a week since eating pine nuts….

    PLease someone let me know what you can eat that will taste normal until this subsides…

  409. Kimmie

    I have now also experienced this weird pine nut induced horror ! I would never have guessed it to be this food to be the culprit , but after reading that it is Chinese version (small/fat nuts) and I usually ate thin italian style pine nuts – YES curse them chinese nuts. The horrible part is that this food was even labelled organic and I payed OVERPRIZE for it. Never again will I buy a product in closed container where I can’t see the nuts. I have now written the producer of the item to make them realise they have a problematic food source. This needs to be avoided – imagine if someone will suffer the rest of their lives with this. It is soon a week and I hope it to go away slowly but for good !

    omg so funny i just started googling my bitter taste simptoms and i found this and omg just what was going through my mind lol! i never ever eat pine nut except for 2 days ago, and what do u know, everything tastes horrible! i got mine in bulk at winco, never again! thanks for the info =)

    Thank goodness for the web and info like this. Add another one to the list of utterly confounded victims of this bizarre syndrome. The nuts in question came from Safeway. Like many reporting here, I have enjoyed pine nuts (probably the ‘original’ Italian ones) without any such symptoms for decades, so the current supply isn’t what it used to be, to say the least. Even if a pine nut showed me an Italian birth certificate, it will be hard to look one in the face again.

    A note on potential remedies. I tried a few things yesterday and today (3rd day) have almost all my normal taste back. First, I chewed a teaspoon of pure dry cornstarch until it became a paste, and brushed my mouth and tongue with a toothbrush thoroughly, then swished and spat. Then I did the same with a teaspoon of dry baking soda. These seemed to have a soothing allopathic effect. Then, since people had reported help from crystallized ginger, I improvised and micro-grated a couple of teaspoons of fresh raw ginger into some honey and gave that a good swish around and swallowing. That had a sort of nuclear homeopathic effect — all the taste buds erupted with full alkaloid alarm bells going, but after that settled down, I had about 50% of normal taste back at dinner, and this morning have nearly all. P.S. for pesto lovers asking about substitutes for pine nuts, I’d suggest using barely toasted cashews and a dash of a decent Retsina.

  414. Nancy

    All right!! Message number 2…. It took me a good 8 days before I could enjoy drinking or eating and not have a bad after taste. Good luck to anyone experiencing this right now. Lesson learned!! Never eating these nuts again!!!

    Thank god for the Internet, victim of Trader Joe’s pine nuts consumed a day ago, in a second day of taste implosion. Can’t wait for normal taste to return. Great article and helpful comments.

    I should have known better. Was visiting relatives over the weekend and saw some fresh home made baklava and a bag of left-over pine nuts they had used to make it sitting on the counter. When I saw them sitting there I thought of an article I had seen about pine-nut mouth but laughed it off and ate about a tablespoons worth anyways, as well as a couple pieces of the baklava.

    Everything tasted fine while I ate it but now 3 days later the overwhelming after taste of metal is driving me nuts! I can only pray this doesn’t last for much longer.

  418. Diane R

    I am so thankful for!!! I also thought I had some dreadful disease. I added pine nuts, which I bought at Trader Joe’s, to meatballs that I made on Sunday. I was out to lunch on Tuesday and thought I ate some bad avocados. After that, everything I ate tasted bad. I told my husband that it was a “metallic” or “medicine” taste that I just couldn’t get rid of. I even tried Salt & Vinegar potato chips which would normally kill anything!! Still that horrible taste. This morning I woke up with a terrible migraine, which caused me to check the internet. I thought for sure there was something wrong. How weird that the first thing that came up was “Pine nuts”. I ate these by the jarful when I was a kid. Who knew?

    3:53 pm  Mar 24th, 2010
  419. John

    Well, add me to the list. Don’t remember where I bought them, or when (awhile ago). Made some pesto in my new blender last night. Bye the way it’s one of those ultra high-powered things. Was wondering if “over-processing” could have exacerbated it. Hearing of the possible two-week-or-longer duration is a bummer. ANYBODY heard of a cure? Oh, well, it’s lent and I might as offer it up.

    4:57 pm  Mar 24th, 2010

    Speaking strictly for me, I’m going with pecans next time. BTW/ vodka martini’s with anchovy olives are not a cure.

    Thank goodness for blogs! So comforting to know that others are going through the ‘bitter’ situation that I am. Yes, I too am a victim of those pine nuts! Am on day 4 of the bitter taste and can’t wait for it to go away. I have been eating oranges and they seem to be the only thing that doesn’t taste bitter to me.The only upside to all of this is that I’m not eating as much as I used to.

    I can’t stand it, every time I eat something, I get a bitter taste in the back of my throat. I did a google search as well, I have been eating pine nuts this week, from Trader Joes…I’ve bought them there before, and never had a problem. Don’t think I will buy them there again. I hope the bitter taste goes away soon. I didn’t even eat that much! Thanks for posting this, it’s nice to know I’m not alone, and to have an answer to this mystery!

  425. Viki

    got this back from Trader Joes…
    Hi Viki,

    We apologize for the experience you recently had with the Trader Joe’s
    Pignolias/Pine nuts purchased in our store. We appreciate you bringing
    your concerns to our attention, and for allowing us the opportunity to
    address them. What many of our customers have recently reported has been
    a naturally occuring situation with the pine nuts, and we assure you
    that it has nothing to do with where they are sourced from. However, our
    pine nuts do not come from China.

    The issue of the taste disturbance experienced after eating the pine
    nuts has been reported from several of our customers recently, as well
    as numerous other cases discussed with other retailer product. Generally
    what occurs (again, this is a naturally occurring phenomenon) after
    eating the pine nuts is that a bitter, metallic taste can develop 1-3
    days after consumption, and can last for days or weeks. However, while
    very unpleasant, it does not represent any health concern. It is also
    not linked to any sort of contamination, pesticides or heavy metals.
    Some of the pine nuts involved in some of the cases reported were from
    China, but this is not the case with all, and there is no conclusive
    link to any particular species or source country.

    Of course, we are offering our customers the option to return the item
    for exchange or refund, and our most sincere apologies (eventhough it is
    not as a result of any fault of ours–it’s nature!).

    Thank you,

    Nicki K.

    If it’s nature – why has this only happened more recently – I think the earliest posting was 2002 wasn’t it? But more so NOW – ie since last summer. It’s easy to say
    ‘However, while very unpleasant, it does not represent any health concern.’
    This is only because someone hasn’t been hospitalised as a result – they need to experience to understand what it’s like! People are feeling very ill due to this – sickness, nausea, headaches, lack of appetite – the responses are too flippent in my mind – it’s easy to dismiss it when you have no experience of it and they know from the complaints that they do get over it. Interesting that the lady at Asda Walmart – where I took mine back to wasn’t willing to try eating any……………

    12:47 pm  Mar 27th, 2010
  427. Nancy G/Olympia

    Very true, Elaine. Since my own episode several months ago, I’ve been looking at the pine nuts offered in the stores in my area. (many come from China)

    I have to wonder though at the possible cause(s) of this strange symptom. Even though it seems there are increasing numbers of afflicted people, I’m surprised each time I read of groups of people eating pine nuts but only one or two actually experiencing any side effects. Clearly some of us are more susceptible than others. Why? Toothpaste? Other foods or chemical reactions? Besides the explanation given by some that it’s the Chinese nuts or the (improper) storage of our nuts I haven’t read anything here on these postings that we all have in common aside from the horrible taste.

    Just an observation….

    1:00 pm  Mar 27th, 2010
  428. anne

    Could this be an interaction with certain medications some of us take?
    Wierd how it affects some and not others who shared the same nuts!
    I guess I won’t be having my favorite appetizer at BJ’s anymore. Avocado
    eggrolls with pine nuts in them. Not worth the risk..

    1:59 pm  Mar 27th, 2010
  429. Elaine (Derby UK)

    Maybe we should make our own investigations…………….are we all on meds? I take meds for rheumatoid arthritis…….What else do we have in common – maybe a new forum is needed?

    4:06 pm  Mar 27th, 2010
  430. Dena Smith

    I am not on any medications at all. Trader Joes pinenuts say that they are from Russia or Korea, when I checked this out…they are actually from China and packaged in Russia.

  431. Susan

    I’m wondering if we’re having an allergic reaction. I made pesto and served it to two other people. They were fine, but I got the bitter taste problem. I’m allergic to mold, dust, cats and some types of pollen.
    The strange thing is that I’ve been eatting pinenuts for years and never had a problem before.

    6:52 pm  Mar 27th, 2010
  432. Donna in Oregon

    I am not on any medications and have no allergies, although wheat can be an irritant to me. (I co experience insomnia frequently.) I had purchased Chinese pine nuts from Costco on 2 previous occasions without problems. I always refrigerate all nuts. Last fall’s experience, combined with this blog and so many others, has convinced me to never try them again. Early on, I found a website that said Chinese people do not eat their variety in the ways we do. I was unable to find it yesterday.

    9:17 am  Mar 28th, 2010
  433. Diane in NJ

    I am not on any medication, and I believe my pine nuts were from our local grocer, Shoprite, and I never had a problem before using them very sparingly – about a tablespoon at a time – but when I ate them in a large quantity is when I had this experience. I have been following these blogs for a while since my incident was many many months ago. I have begun to keep all my nuts refrigerated since the oils spoil quickly, but I am tending to believe my incident was based on quantity. Anyway, my experience was drastic enough to make me give them up forever, no matter what the quantity!

    9:51 am  Mar 28th, 2010
  434. sandy

    i cant belive this..i just googled my symptoms too and realised that i had pine nuts for the first time ever two days ago…never again will i take the chance in eating them cause really! everything ive been eating tastes so so so bad!

    10:42 am  Mar 28th, 2010
  435. Nancy G/Olympia

    I’m not on any medications either. No allergies that I know of. I agree with Diane in NJ in that I wonder if this is a quantity issue. I have never had problems before my episode but when I did have my problems I was eating handfuls over a period of two or three days. I haven’t dared to eat from the same bag or any other since that episode. Maybe it’s time to test….

    1:04 pm  Mar 28th, 2010
  436. Elaine (Derby UK)

    Quantity was not my experience – I bought a tub of ‘snack’ nuts and seeds. So at most there was no more than a dessertspoonful. The taste came 2 days after and lasted about 6 days in total. (4 really bad) I just ate a few, barely a 1/5 of the pot in total.

    1:35 pm  Mar 28th, 2010
  437. DrEeveal

    My wife and I have the same thing. I made some creamed spinach with pinenuts last week, symptoms didn’t arrive for a day or two later – it’s been driving us crazy. Good to know others haven’t been dropping dead from it. Yet. Our pinenuts were from Oregon btw, not China…

    1:28 pm  Mar 29th, 2010
  438. Cheryl Meril

    This is really amazing. I had pine nuts a few days ago that were very bitter. Extremely bitter in fact. I thought it was bad soup I put them in. The next day everything tasted bitter. I typed in “food tastes bitter symptom” and lo and behold confirmed its the pine nuts. Mine are not from Trader Joes however though I’ve bought them there before.

    I guess I”ll be phasing them out because it’s not worth the trouble. Besides, they’re expensive!

    Correction: My pinenuts were in fact a product from China, just distributed by Western Family out of Oregon.

    I love Google. Mystery solved. It started with some homemade bean soup I made in the crock pot during the night. I tried it this morning early and thought I somehow messed it up. I then had to go out of town. While on the road, I had a noodle bowl for lunch and then had a weird bitter taste in my mouth after. Later, I had a coke and the same thing happened. I was really starting to worry. Before I headed back home I got a cup of coffee and a cookie and the same thing. I called my sister and asked her to google it. The first thing she asked was if I had eaten pine nuts. Sure enough, I had them (Trader Joe’s version not stored in the fridge) two nights ago in pasta sauce. I’m not allergic to anything and take no meds. I hope it goes away soon, but at least my soup could still be good. Thanks, everyone, for sharing.

    Oh thank goodness, I was really wondering what was the matter with me, when everthing started tasting so bad after eating. I am an Aussie who eats pine nuts all the time, I have just returned from vaction to Hawaii where on my last meal there were a whole lot of those little suckers! Day 4 now and things are improving, lets hope those dodgy pine nuts don’t make their way down under!
    Thanks eveyone for sharing your thoughts now I know I’m not going made.

    I thought this problem was from the new toothpaste I bought. Go figure huh? I bought my pine nuts at Trader Joes and will be returning them ASAP! My mouth feels like I have been sipping on syrup of ipecac all day. Yuck!! Good way to diet I guess…

    My husband and I went RAW and we have had this horrible bitter taste in our mouths for over a week. I thought I did not rinse the soap off the dishes good enough or that the beet greens alkaloids were bitter and staying in us for a long time. I thought, “Gee, organic just doesn’t taste as good as it used to.” Then I thought, “Nope, it’s this olive oil.” So, I got rid of that. Then I decided to google, “I have gone RAW and my mouth is always bitter” and got this site. Bingo. Trader Joe Pine Nuts. One and a half bags in a week and a half. I don’t think it is just Trader Joe’s but any pine nut as I remember they kind of did that too me too when I was little. We would sometimes gather them off of the ground in New Mexico. I love Trader Joes BTW.

    Thank you for posting….. I just made a recipe with Spinich/Mushrooms/Pine Nuts and the after taste is HORRIBLE. I am throwing my nuts away. Don’t eat them enough to miss them but probably won’t be eating them in the future.

    Just read a bunch of other comments. My allergies are dust/mold/dogs/cats (still keep them around though cause I love em!) and have been taking xanax lately for stress. Maybe that’s it cause I don’t remember pine nuts causing me issues before. Anyone else?

    I was doing some thinking and this bitter taste is similar to the taste of the supplement MSM which has a form of sulphur in it. Being a classical homeopath (homeopathy works on the basis of similarities) I decided I would suck on one pellet of homeopathic Sulphur 6c. It has helped. The bitterness is down by about 80%. I’ll try another one to see if I can get this to go completely away. That’s probably all I will need to take. Could be also that this just went away on it’s own….but, I don’t think so.

    On Saturday I ate a small handfull of pinenuts (from China). On Monday i noticed the bitter after taste of everything except water and green tea. I have never heard of this happening before but i am now relieved to find im not alone. I just hope it does not last too long. Today is day 2 and i have a mild headache but its probably not related.

    Onna: Please don’t through the pine-nuts away. Take them back to the store, even if the package is gone. They have to have lots of returns before they are convinced.

    Anna: Thanks for the Homeopathic tip. How long had your symptoms been occurring?

    (Strong Ginger Tea worked for me.)

    I had the taste in my mouth for over a week. I ended up not repeating the Sulphur 6c and I would say the bitter taste is about at 1%. I just let that initial dose keep working. My husband flew to London and SMSd me and said he still has the horrible taste at 100%. I didn’t think about the homeopathic sulphur when he was here. Dang!

    Steve- I just moved from Australia and I ate a bag of pine nuts there a couple of months ago from the IGA and did not have this happen. That’s why I didn’t think anything of making the pesto out of a cup and a half of pine nuts.

    I should have taken the nuts back to Trader Joes but I threw out the package and after this episode I threw out the nuts.

    This is amazing! I’m so happy to know what it is!!! Just the other day I noticed a bitter taste in my mouth. I was about to throw several things in my refrigerator out, thinking something was wrong with the food…until I realized that EVERYTHING, even just swallowing the spit in my mouth tasted bitter. Now I know! For the first time in years, I started this week eating Pine Nuts. I mixed them up with some other nuts and made little snack bags for myself – but they are not refrigerated. Maybe they went bad. Whatever. All I know is I’m through with them! This bitter taste is horrible and I hope it wears off soon. I’m glad I decided to do a Google Search — Thank goodness for the internet!

    April 8, while out at a very good restaurant, to celebrate my birthday with friends, I had an arugala salad that had pine nuts in it. I haven’t eaten any pine nuts for years. About 24 hours later everything tasted bitter. I was scared and googled and got scareder! Then I found this site and put it together. Ahhh! I don’t have cancer.
    Thanks for all the info.

    I ate pine nuts on Friday (don’t think I’d ever eaten them before) at someone’s house. I think they’d been around a while. Since Sunday morning I have a bitter taste in my mouth. I was about to head off to the doctor, but after seeing this I’ll wait and see.

    What would we do without the internet…?!

    Thanks guys.

    I was eyeing the offending bag of pine nuts that I’ve saved for several weeks now in case the FDA wanted to test them (they have not responded to my e-mail inquiry), and wondered how many new reports there were here. My gosh, they keep pouring in! I have had no food allergies, take no meds, and before the awful recent experience had eaten pine nuts for 30 years with no reactions. Notwithstanding that people do not go into shock and eventually recover, the severity and duration of the symptoms suggest some sort of toxicity that even symptomless persons might do well to avoid. From all these reports, it sounds like some previously unharvested variety of pine nut, or contamination, and I hope the authorities get on it.

    OH MY GOD!

    I’ve had this bad taste in my mouth ALL day long… I googled to find out what is wrong with me and this site came up at the top. And guess what I ate yesterday? A heaping plate of pesto lasagna (filled with Trader Joes dry roasted pine nuts!).

    After reading your post and many of the other comments, it seems that there have been many cases of this bad taste phenomena after eating our trusted Trader JoJo’s nuts.

    I’m still reading through comments (I just felt the extreme need to comment after my sudden TraderJoes-pine-nut-epiphany) but I wonder what causes this? I don’t know, but I do know I will keep my distance with pine nuts for a while.

    Some good news people….. it doesnt seem to happen every time. Its been a few months since I ate pine nuts as I wanted to avoid the unpleasant situation happening again, but at a friends place 2 weeks ago she made some fresh pine nut pesto to eat with crackers.
    I ate quite a lot as it was very tasty – best news though is that I didnt get “pine mouth” afterwards!!!!! So pine nuts lovers out there, dont give up on them forever, it might not happen again 🙂

    was going crazy with my breath feeling rancid and pukey with a stuffed nose on top of it and sinus headache. But each night this week I’d been eating a salad with pine nuts I’d found in the back of the fridge– haha, lucky me! -.-

    My god I hope it finishes soon. I had the nuts on Monday, symptoms showed on Wednesday and now its Friday afternoon. My metalic fruit salad & honey was awful for lunch. I wonder if there has been anyone who has done the scientific research into this? I don’t really want to eat pine nuts again. If I hadn’t of found this blog, i would have been really worried.

    Add me to the list. Yesterday, everything I ate tasted horrible. I made tacos for dinner and I could not figure out what tasted so horrible in it. Everyone else thought they tasted great. I was blaming the taco sauce, cheese, meat, my freshly gound cumin. I could not figure it out.

    Then today, I get the same taste in my mouth. HMMMMM. Google to the resuce. I threw some pine nuts(toasted) on top of a tuna salad 3 days prior. They were Melissa’s brand pine nuts (from China, go figure). Brand new, just opened, stored in the refrigerator.

    I have been eating pine nuts my enitre life with no problems ever. In fact a week ago I used a bag of toasted pine nuts for pesto and had no problem (I wish I still had the package). I will be calling Mellisa’s as soon as I step away from the computer. And refraining from eating for a few days I’m afraid. This is just GROSS.

    As a follow up, I am not on any medication and I was the only one in the house to eat this particular batch of pine nuts. Part of me wants to get my jerk boybriend to eat some, but even I am not that cruel. LOL

    I have been suffering from the same problem. I was going crazy trying to figure out what was wrong with me. Finally found on Google that the horrible taste I have been experiencing could be pine mouth. Now I had to figure out where I had eaten them since I couldn’t recall eating whole pine nuts. Finally solved the mystery. I had purchased a bag of Mrs. Mays natural sesame snacks (manufactured in China) and the second ingredient is PINE NUTS! I have thrown the bag out and cannot wait for my taste to return to normal. I miss tasting my coffee and wine and will never eat pine nuts again.

    I am very grateful for this forum. I bought some Pine Nuts last weekend (exactly a week ago) from Kroger, Product of China. I have been tossing them on my salad all week and got the onset of bitterness on Wed night. It got very strong today (Saturday) and I am HOPING this will go away soon. I have eaten Pine Nuts for years on occasion and have NEVER experienced this. China is so incredibly polluted, I can’t help but imagine it is a level of poisoning. . . I just wish I knew what poisoning it is and is this neurotoxic (?). . . It will be a long time before I have Pine Nuts again, and I will never buy them from China again. Even though this has not been pleasant, I have LMAO at many of the comments here! “metal ass mouth” and the guy who said he’d love to get stoned but even his dope tasted bad. OMG. And the person who decided to use Tomato Juice because it works to get skunk off dogs!! too funny . . . . cheers, peace out.

    omg thank u for this posting! i got a bitter taste in my mouth when i was pregnant with my first child and i just gave birth to another little girl 3 months ago so when this bitter taste started 3 days ago i’ve been in a panic ever since!! i go in to get my tubes tied next week so i guess this will be my husband and i’s last scare! lol we ate pine nuts on our salad a couple nights ago and it was the first time in years ive had them. so i’m pretty sure seeing how thats my only symptom i ate bad pine nuts and not pregnant again! but i’ll laugh about this after my tubes are tied! 🙂

    Returning to let everyone know something that works to alleviate the bitterness (but won’t make it go away). . . chewing gum. I’m sure many types will work, but I bought Cinnamon Altoids gum and it was a pleasant diversion from the rotten metal taste. I’m on day 7 and my taste is about 90% back to normal. Best of luck to everyone. Why doesn’t the news report this so we are not finding out after the fact. . . ?

  472. thatgirl858

    gum worked for me as well. another thing that seemed to help when I went out to dinner (reluctantly) the other night was vodka! I had a dirty martini and it seemed to help a lot. I know vodka is known to help open the taste buds and it worked for me. not that i would drink vodka everyday to get through this horrible experience, even though it would make it more enjoyable 😉 my taste is pretty close to returning to normal as well, this whole nightmare started a week ago today.

    I too am having the joys of pine nut mouth – I was excited that I finally had enough basil in my garden to make pesto whipped up a batch and generously put it through my freshly made pasta that night I have terrible cramps and the following day everything tasted metalic I am on my 4 day getting fed up now as I would actually like to eat something with out the taste being destroyed how can this be acceptable for so long you started this blog last year and still it continues?? I thought I had something terrible glad I googled it before going to the doctors – bless google 🙂 and you!

    I am experiencing the exact same problem. It hit me last night slightly and is absolutely horrible today. I had pine nuts (from Trader Joe’s) on Sunday night and in leftovers on Monday… won’t be buying those again. I have been boycotting food all day… but since everybody is saying it takes about a week to get over I guess I am just going to have to suck it up. 🙁 Mint gum tastes terrible… but cinnamon works. I will try the vodka next!

    Hi All, I’m convinced that there’s something going on with the pinenuts from China. I had pine mouth a couple months ago and I finally got up the courage to try what I think were Italian pinenuts. I went to a bakery this past Saturday, and everyone at my table was munching on macaroons toped with large elongated pinenuts. I had a hard time resisting, and ate one of the cookies. That was five days ago and I haven’t gotten pine mouth. I’m going to hunt down some Italian pinenuts and try them again.

    Happy it came up in google after I typed in “bitter taste”. This was driving me crazy. I suspected the pine nuts but thought it sounded odd. Happened twice with Kirkland brand from Costco.

    I see Trader Joe’s listed on here by a lot of posters but I got a bag from Sam’s Club:

    Amport Foods brand, “Product of China” booo China!

    I ate 2 handfuls worth on salads a few days ago now everything food or drink-wise that goes in my mouth tastes like a burning tire.

    It’s probably a subversive plot to take out the healthiest Americans… I’ll bet they’re marinated in mustard gas! o.O

    Wow. I’m not dying! I have been suffering for 4 days (6 days after consumption). Thought for sure it was my new low carb high protein diet. This makes more sense. Thanks to all who posted! I purchased mine from Asda in Aberdeen, Scotland In January and have been kept in a cool place since then. I had no idea that they shoudl be kept refridgerated. (Dumb, but I really didn’t know). I’ll never eat them again. This is horrible! It’s like mercury at the back of my throat and the top of the back of the mouth. Nothing makes it better, except a cheeseburger. Go figure!

    Wow, well someone took this seriously. (from New Mexico, so probably eats pine nuts more often than some of us further north). I’m still interested in figuring out why this happened and what can be done to prevent it happening again. I’m not brave enough to try two-three handfuls again soon, though (as someone a few weeks back reported doing).

    I ate pine nuts on a salad in a restaurant last Saturday evening and developed metallic taste (and tingling in mouth and lips) on Monday. Was at it’s worst on Tuesday and most of Wednesday. It’s now Thursday and I am really pleased to say it’s getting better (sometimes bitter taste but generally bearable). Horrible experience. I am never eating pine nuts again.

    Well, I’ll be damned… Wife and I have bad colds/bronchitis and have been popping guaifenisin pills like candy. Got the bitter taste for the last few days, and theorized it was the guai. since it’s an expectorant and presumably gets secreted along with the stuff it’s helping you get rid of. But I couldn’t find it listed as a side-effect–not even a rare one.

    Then I stumbled upon this, and… hello! What have I been munching at my desk, after weeks of illness and with practically nothing else left in the kitchen? A big, honkin’ bag of Trader Joe’s pine nuts. I’d never have guessed there could be a connection.

    They were lousy pine-nuts anyway, but now I have another great reason to avoid them.

  490. Heather H.

    I developed the same problem exactly a week ago. I bought the 4 oz bag of “Toasted Pine Nuts” from Trader Joe’s to sprinkle in my pasta w/ garlic, olive oil & fresh basil. Sure enough, the next day I noticed the funky taste in my mouth. It’s horrible! It’s really bad after consuming dairy products. I will *never buy pine nuts from Trader Joe’s again, that’s for sure!

    I’m a little reluctant to say this in case its not true but….I think its gone!! 7 days. Fingers crossed. Every morning its been like groundhog day, wake up have sip of coffee, think it’s going to be ok and then after swallowing–AAARGHHH. Now tonight (I’m in UK) it feels different, I can’t remember it after dinner… pleeeaase let it be gone…..
    Speedy recovery to all of you. I won’t be having pine nuts again.

    …sure glad I found this site…whew…going to wait and see if my taste buds get back to normal…before I meet the Grim Reaper…
    …reminded me of a time when I was a teen…watching movies in a dark room…stuffing my face with cheese-its…turned on the lights…the box was full of black ants…they tasted like little pieces of pepper…ugh…so I went thru all my boxes of food…nope…those darn pine nuts..have to be the culprit…think my friend got them at a Safeway in Santa Cruz area…

    It is quite remarkable to see how common this has been. I also consumed pine nuts from Trader Joes in Portland, OR (a few handfuls on a salad) and 2 days later developed the bitter taste sensation. I am at day 3 post-consumption and am still experiencing the same symptoms. I usually buy large quantities of pine nuts from Costco to make pesto but have never had any problems with these. I have noticed the bitterness is particularly noticeable following consumption of the following food items: granola, sweet chai tea, chocolate biscuits, breadsticks, broccoli, strawberries, red wine. Savory or salty foods do not seem to cause the symptoms to the same degree. Hoping it goes away soon!

    OMG! I just ate a salad with a bunch of pine nuts on Wednesday. Yesterday I couldn’t get this horrible bitter almost metalic taste out of my mouth. Everything I ate, I started throwing my food away thinking the food in the frig went bad. But yes everything I eat tastes bitter!! Two days now and I’m still can’t eat or drink anything. I even drank sprite and it had no taste. It’s like it’s blocking the other taste buds. The pine nuts came from a publix brand jar, although I added an opened package of pine nuts that were about three weeks old to it. So I don’t know which pine nuts might have been rancid. All I know is that I’m not crazy thinking that I’m dying of cancer or that someone’s trying to poison me. I can’t wait for this horrible taste to go away. Even toothpaste tastes bad! Well good luck to all of you, but I think I will stay away from Pine nuts for a while.

    I googled “bitter taste in mouth” because I have been suffering from it for 3 days now. I came across your article and realized the pine nuts I have been eating were most likely the culprit. I bought “Melissa’s Pine Nuts” (Product of China) from Super Target last weekend. I’ve learned my lesson. Yuck!!!

    I must say I’m amazed once more–this time at the steady stream of replies to this year-old blog post (guess I was signed up for email notifications by default). There really ought to be a PSA about something this wide-spread (“This is your tongue…This is your tongue on PINE NUTS! Any questions?”), or maybe even an FDA action.

    I know the pine-nut vendors say that it’s all “natural” and not a health threat, etc–but having your sense of taste corrupted for up to 2 weeks is not a minor thing, and it isn’t what consumers are expecting…and there’s certainly no warning about it on the packet!

    I had pine nuts from Trader Joe’s on Friday and the bitter taste started on Sunday everytime I ate. Today is Monday, I’m having lunch at my desk and decided to google it, since my sandwich is tasting very bitter. Bingo! It was the pine nuts from Trader Joe’s. Thanks for this article!

    I purchased the same Trader Joes pine nuts and am having the same problem. How weird! Hope it isn’t serious like everyone seems to think, and will also go away sooner than later.

    I never eat pine-nuts and was at a relatives house Saturday and ate 2 pine-nuts that tasted bitter so I figured they were rancid-since then I’ve had this bitter taste in the back of my mouth that will not go away-everything tastes bad-thank goodness I Googled it and found this because I suspected the the pine-nuts but doubted that the bitter taste would last this long after eating just two!
    I will never eat them again that’s for sure!
    This site really helped me feel like I’m not… hmm… ”nuts”!

    Please, all you new victims; Take the nuts back to place of purchase, It is not just Trader Joe’s. It was Costco for me.

    Even if you no longer have the receipt or the package, take them back. We still have to keep letting them know. Make sure other customers are around when you politely explain what is happening to thousands of people all over the world.

    I live in UK. 10 days ago I ate a bag of Chinese pine nuts with my 28 month old son. 24 hours later and suddenly he just started screaming and saying his tummy hurt. He is hardly ever sick and has only vomited once before (healthy breastfed toddler!). Within an hour, he had a fever of 40 and was violently sick. The cramps continued for the next 12 hrs followed by his reactive refusal of all foods and liquids. I also developed stomach cramps, and then the foul bitter taste. I’ve still got it though toddler has just resumed normal eating. No other causes found.

    What is going on? Given track record of poisons in Chinese goods, why is there not more happening?

    I am so relieved to find an answer to the mysterious bitter taste in my mouth. Last week I bought dry-roasted pine nuts from TJs and made pesto. I’ve cooked with pine nuts for years but this is the first time I’ve had the bitter taste.

    Thank you for this information!

    I learned from a nut and dried fruit distributor that the reaction to pine nuts is not because of the quality, but an allergic reaction that many people have to tree nuts. He receives an e mail about once a month asking the same question about pine nuts. His response is don’t eat them if it happens to you. PS …. I love Trader Joes

    I don’t agree. I have eaten pine nuts for years – often by the handful. Many people who have posted say the same – this has never hapened before.
    It may be as Roger Hyam ( says in his report that it is a different breed of the nut – a smaller version, but this many people in the world cannot be allergic – when they’ve not been before – and we’re the lucky ones! We know what’s happening by sharing this info – and thanks to everyone who has posted – but what about all the others – who havent yet discovered this site or what the cause of their quite scary symptoms are, and are seeking medical advice? Some serious investigations should be done – no-one ‘who matters’ seems to be taking it seriously. Because no-one has died and symptoms seem to go after about a week – they are saying ‘There is no health risk’………but do we REALLY know this?

    To Jodi especially: I believe your fruit and nut distributor is incorrect. I have no allergies of any kind and this happened to me. Elaine in UK referred to an important article about this being a different variety of pinenut. I lost the link, but read somewhere that Chinese people do not normally eat these things.

    Yep, trader Joe’s for me also. I got the nuts last week to make pesto this week. I love pine nuts and make pesto a few times a year..The nuts did not stay unopened. I bought them Friday and had a palm full of them. Sunday and Monday had the metallic taste. Had a spicy lunch on Tues and didn’t notice much of a bitter taste, just slightly,BUT silly me goes and eats another palm full of of nuts Tuesday and lucky me I have had the absolute worst metallic bitter taste in my mouth today. Much worse than Mon and Tues. I have no idea how long this will last. I will try the ginger. I did find on Mon I ate the mandarin oranges canned and they were the only thing that did not leave a bitter taste. Gonna eat them again tonight..I tried a lunch and it almost made me vomit the bitterness.
    I will contact the FDA at the number I saw previously listed..404-253-1256 and give them my info. I am also going to contact Trader Joe’s and tell them whats up. Everyone needs to contact them as it seems they are the largest culprit here. I read earlier one person said they were told by Trader Joes that they no longer carried the nuts from China. Several have researched the Vietnam, Korea or Russia source and have found that the actual nut does indeed come from China. Well Trader Joes my bag says Vietnam, Korea or Russia, so I was assume you are wrong!
    Other symptoms for me is I have been exceptionally nautious this week and have had stomach cramps. Maybe due to other things, but as I know myself, the timing is a bit odd! I love Trader Joes but they need to stop carrying these nuts from this source until its figured out by the FDA…Sucks, I love pine nuts, but I will not buy them any longer unless they are from a well known source that is not affiliated with Asia.

    Curtis, I have to agree with Donna in Oregon that what you were told sounds like a cop-out. I have no known allergies. I’ve definitely never had an allergic reaction to pine nuts in any form before my episode last summer. (and I’ve been eating pine nuts and pesto since the ’80’s!) Something is up!

    10:18 pm  May 13th, 2010
  512. Lei

    …Hi Curtis…got to agree with the gang…I have no allergies to any nuts….well maybe a few walkin’ around…but gotta say..I eat pesto pizza…and pesto in any way I can get it…and for 40+ yrs….so guess your distributor is covering his butt…my pesto in my fridge never did this…so definitely a bad batch out there…by the way…our pine nuts came from a Safeway in Santa Cruz…not TJ’s…

    10:19 am  May 14th, 2010
  513. Michael

    Hi all, I reported my encounter with this nasty syndrome in March, having eaten pine nuts for years, and with no history of any food allergies. The source was a Safeway in Northern California. I e-mailed the FDA through their website and just heard back today, directing me to these numbers, which victims in California may wish to call:

    “You can file a complaint with the FDA complaint coordinator that handles CA by contacting California (Northern)–(510) 337-6741 or California (Southern)–(949) 608-3530.”

    I don’t think the symptoms are trivial, and are certainly not an allergy. I’m not a doctor, but the experiences reported here more likely suggest to me a neurotoxin, possibly from fungus, mold or insect contamination. I don’t think testing for heavy-metals or pesticides alone is enough to dismiss the phenomenon as “harmless.”

    I hope someone who still has some of these rancid pinenuts will contact their local news station, that has an Help/Action reporting segment. It would be interesting to have a News Station have an independent laboratory do an analysis and subsequent report on these nuts, to see if any [bad?] chemicals were added to them (by who knows who?) and what if any side effects (immediate and future) could be expected as a result of eating them.

    9:26 pm  May 14th, 2010
  516. Cy

    Or better yet send them to Dr. Oz’s show for them to do lab analysis and a segment of the show about Purveyors of Putrid Pinenuts!
    What do you think Dr. Oz?

    Thanks guys,
    I’m on my second week of bitter mouth taste and was getting ready to setup an appointment with my doctor. I had never eaten pine nuts until a recipe called for it and then I purchased it from….Trader Joe’s!!! Well thanks to you I now know the cause. I still have half of the bag but will not be having any more.

    I too am suffering with pine mouth. In doing some research I found a comment suggesting the bitter aftertaste was a result of combining pine nuts with citrus–apparently triggering some sort of liver cleansing action and the taste is related to that. I have no medical background and can’t confirm any of this, however, I did drink two orange and lemon drinks mixed with mineral water at the same meal I consumed the pine nuts. Did anyone else combine citrus with the pine nuts?

    11:23 am  May 18th, 2010
  520. Brian

    OMG, I can’t believe I found this posting, and more amazingly that there are soooo many people who have had the same experience. I hardly ever eat pine nuts, but sure enough a couple of days ago I had a bunch. Did not combine with citrus, though. My GF ate the same exact meal, and she has no such symptoms. I’m thinking that there’s a genetic component.

    3:52 pm  May 18th, 2010
  521. Lei

    Hi Brian…you know…it is kind of weird…I asked my friend if she still had the pine nuts that gave me the problem…she says…Nope ! …I ate the rest of them…so what’s up with that…how come some of us are affected…and other’s skate by with no symptoms?

    I had pesto from Costco (their Kirkland brand) on Sunday night. Monday evening, I poured a glass of red wine and almost spit it out. It tasted horrible, bitter. Thought it was a bad bottle. We went to dinner at a pizza place and I noticed then that the same bad taste was in my mouth while eating pizza and drinking another glad of chianti that I knew was good. So I’m very relieved to know the cause. Don’t know if the pine nuts in the costco pesto comes from any particular place, but it sounds like their pine nuts come from China so maybe their pesto does too. Anyway, I hope this goes away soon. The bummer is we’re headed to a five star restaurant tonight.

    I’ve eaten pine nuts for years, make pesto every week in the summer — keep them in the fridge and generally buy them in bulk from Whole Foods and never had a problem.

    Will try the ginger with hopes I can enjoy food this week — my niece get’s married on Friday, so bummed nothing is tasting good

    Lei and Brian, I think it is a matter of susceptibility kind of like what we see with some people who eat asparagus and have smelly urine while others aren’t affected.

    “Asparagus, a green vegetable belonging to the lily family, has one notorious side effect for some diners who eat enough of it. Within a half-hour of asparagus consumption, some people notice their urine has acquired a very pungent odor, often compared to rotting cabbage, ammonia or rotten eggs. The effects of asparagus on urine are generally fleeting and harmless, but it’s not necessarily the consumer’s finest hour, bodily excretion-wise.
    The good news is that asparagus does not affect everyone. Studies conducted on the “asparagus urine” phenomenon (aren’t you glad you didn’t volunteer!) indicate that roughly 40 to 50 percent of those tested developed the distinctive odor. Surprisingly enough, there is also a segment of the population who cannot smell the sulphurous fumes of asparagus-laced urine. It is believed that both the generation of the odoriferous urine and the ability to smell it are based on genetics. Only those with a certain gene can break down the chemicals inside the asparagus into their smelly components, and only those with the proper gene can smell the results of that chemical breakdown.

    Scientists are still not entirely sure which set of chemical compounds contained in asparagus actually cause the smelly pee. The stalks themselves do not acquire a similar odor as they are prepared, so whatever happens most likely happens after ingestion. Experts believe that those with a certain gene produce a digestive enzyme which breaks down the asparagus into various chemical compounds. One of those compounds is called methyl mercaptan, which is the same chemical which gives a skunk its defensive smell. One theory suggests that asparagus breaks down quickly in the body and an enzyme releases methyl mercaptan, which eventually goes through the kidneys and is excreted as a waste product in the urine.

    Others suggest that the asparagus smell is created by other chemical compounds called thioesters. There is also a compound called asparagusic acid, which is not surprisingly found primarily in asparagus. If these compounds are broken down and mixed with the genetically-created enzyme, the results could be a strong smelling urine. This smell is actually considered to be good news, since it proves that the asparagus eater’s kidneys are functioning as they should.”

    I am so grateful for these posts because my bitter taste/pine nut story is like so many I just read. I made pesto this weekend (with pine nuts from Trader Joes Bakersfield, Ca) and of course ate some of the left over roasted nuts by themselves. A few days later food started tasting bitter and then a lingering bitter taste. As it persisted I started researching causes–I would have never associated the two things without this site. I’m so relieved to have an explanation and not worry about possibly having had a strange chemical exposure or something.

    Trader Joe’s should be ashamed! Ate pine nuts from that store at my friend’s house, and got this terrible flavor. Prior to this, ate pine nuts from a co-op all the time, and never had a problem like this. Trader Joe’s is selling Rancid cheap food to maximize profits. Everyone should prioritize their health and well-being and abandon this ugly corporation! Find or start a co-op in your neighborhood! As for Trader Joe’s, They are asking for a class action law suit. It has been over a year since this article came out, and they continue to poison us with their rancid products!

    I hope Lulu signed up to this blog. It is not just Trader Joe’s. It is Chinese pine nuts.
    Mine were from Costco. They were sold at many retail outlets. Joe’s and Costco just happen to be huge. They should all be ashamed for continuing to sell these things, but it is our duty to let them know with calls and letters and returned products how widespread this problem is.

    I had a few pine nuts on a homemade pizza Sunday and Tuesday started experiencing the nasty bitter taste after eating.

    Our pine nuts were labeled “David Lewis Orchards” but on the back say “COD China – mfg. in a plant that may use sulphur dioxide, peanuts, other nuts, dairy, soy & wheat.”

    I am allergic to sulfa drugs (e.g., the antibiotic bactrim makes me break out in hives) and given the label warning wonder if there is a connection. Is there some sulpha product being used in the Chinese processing of pine nuts that triggers a reaction in people sensitive to sulpha? Apparently about 3% of people are allergic to sulfa:

    Wow, so relieved to figure out why I’ve been having this bitter/metallic taste at the back of my throat every time I eat or drink something for the past few days. Last weekend I made a pasta salad with lots of pine nuts and I enjoyed the leftovers for the next couple of days, then started getting the symptoms. Oddly, I also woke up with an occular migrane this morning and was astounded that you said you got a headache as well. I was really getting worried that something more serious was going on, but thanks to unearthing this information I now feel comfortable waiting it out a few more days. Thank you!

    Thank god for this blog! I recently bought a small bag of bulk pine nuts for a “make your own pizza night” with the kids on a Friday. My individual pizza was loaded with them, and I had been popping a small had full as a snack all weekend thinking at $23.00 a pound I was indulging in a super cool treat just for me. Well by noon on Sunday I suddenly had this horrible taste in my mouth that I could not get rid of. I’m horrified that I’ve got dragon breath to go with it so I’m on the gum and mint kick, but even super minty gum taste bad. I hope it resolves it self quickly. For now it’s working pretty well as a wait loss program because even snack foods taste like crud and it seems to be “enhanced” by eating or drinking anything. I’ll be pounding water all day in hopes to flush it out of my system and tossing my left over pine nuts tonight.

    I had ‘pine nut mouth’ about 8 mos. ago and found this site.
    It lasted about a week and was from a salad at a restaurant.
    I sent an e-mail to let them know ,but I’m sure restaurants overlook
    this kind of situation due to buying in bulk or they thought I was nuts.
    Anyway just last week I had a very mild type of pine mouth but had not eaten
    pine nut foods of any kind, Won’t do that again! I racked my brain to figure
    out what it was and all I could come up with was the Crest white strips
    I had been using the last 4 days could be expired. The box was gone and I
    had no date. Well I know they had been around awhile. It’s was mild but all the same symptoms. Old peroxide perhaps? strange….. A.

    Another victim (I think, since I just started looking into this). My wife made a strawberry crumble for dessert Saturday night with pine nuts from Union Market in Park Slope. Sunday I was fine, but yesterday and today I’ve had the persistent metallic, sour, medicinal taste in the back of my mouth. Like when you dry swallow a pill. Only occurs when I eat or drink ANYTHING. Trying to see if anyone else who had the dessert has similar symptoms.

    7:40 am  Jun 8th, 2010
  541. Tracyjean

    Clarence, my Pine Mouth issue is exactly the same as yours. My first serving of pine nuts was on a Friday night, a few hand fulls followed on Saturday, and on Sunday while shopping at Sam’s Club around lunch time, I ate a sample of a cheese ravioli and instantly got this horrible medicine/disinfectant/bitter/yuck mouth taste in my mouth. At first I thought it was from the sample food, but the taste would not leave my mouth all day and every time I ate or drank something it seemed to be “reactivated”. It’s getting better but is still a problem on Tuesday. My close friends insure me that my breath doesn’t stink so I guess I’ll just press on and pound fluids and hope to wash it away.

    I m having a bad taste at the rear of my mouth everytime i eat or drink anything even water or coffee its drivingt me crazy have had it for about 2 days now . I ate pine nuts 4 days ago but only a hand full not even that much. thank you all for your stories.

    A way to stop the taste as much but not completely is to brush the back of your tongue , cleaning it as good as possible has given me a bit of relief. Please anyone try it I would like to hear your feed back cheers

    Me too! Pine nuts from Trader Joe’s just like a few other posts. My husband and daughter ate the same dish but didn’t have any taste disturbance, but I munched them from the bag while I was cooking.

    thank you blogger and thank you the universe for google! i have been experiencing the bitter taste in the back of my mouth for several days-and not feeling so great either. ( wondering if there is a connection) sure enough, I made a big batch of pesto with my TRADER JOE”S pine nuts. It’s curious, because I noticed this particular bag the nuts were much smaller and when I opened the bag I could smell the scent of pine. I had never smelled that before and I use a lot of pine nuts.
    My lymph nodes are very swollen and I did have a headache but, like I said, this could be a coincidence.
    I will definitely bring back my bag to Trader Joes and give them this URL. They need to pull these off the racks. My daughter works there and I’ll make sure they hear about it. I know they had changed who they were buying pine nuts from because they were responding to concerns about Chinese pine nuts. The bag I bought said they were a product of Korea. I live in Arizona.

    What a deterrent to eating! My pine nuts were also Trader Joe’s from Korea,Russia or Vietnam. They were just purchased at the TJ’s near LAX and brought to me here in Florida the next day. I used all the basil out of my garden to make pesto and now this! yuck. My husband and I both are suffering from pine nut tongue. The pine nuts I have been using from my local market are from China and they didn’t have this affect on either of us. Twice the price of Trader Joes’ , but who cares?
    Pesto is great made with toasted pecans and much cheaper – so guess who is giving up pine nuts? You got it! I have tried a lot of others spices to try to offset this and nothing has worked – tried chili oil, avocado, tumeric, garlic, parsley, arugala (yIkes, that one was bad) and chocolate mint from my garden which was pleasant – am eating it now but the bitter is slightly coming through.

    I did talk with the manager at my Trader Joes and he mentioned that the FDA is looking at a recall of some pine nuts-not because they are toxic but for taste reasons. I bet this is the reason. I urge all of you to make it a point to discuss this with the store you bought them in-if enough of them are returned they will do something about it.
    I gave them a note with this URL on it so they could see for themselves.
    Today I still have the taste but it is getting better.
    Did anyone have any other symptoms-headach, swollen lymph glands or general muscle ache or fatigue?

    It’s basil season again here in the Pacific Northwest. I have just harvested some basil and started thinking of making pesto. I decided to buy a few pine nuts from my local store to test them out before making pesto with “tainted” nuts. I’m happy to report that these nuts are labeled to have come from the US and that I had no metalic taste after eating a handful!!! I’m so happy!!!

    All of this makes me wonder (yet again) what it is that sets off this phenomenon. I’m buying from the same store, I swear the sign said US nuts last year….
    Are there more of us brave souls who have tried pine nuts again now that summer (and pesto season) are here again??

    Hi again,

    I returned both packages I had in the freezer that I had eaten from to Trader Joe’s. They are taking this very seriously. They refunded my money and sent me a small gift card. They took notes about the complaint and said they would keep me posted on the investigation. I didn’t realize how expensive pine nuts are! More than $7 a package! The Barefoot Contessa has a fabulous recipe for pesto with walnuts and pine nuts. I wonder if you could make it with only walnuts.

    I would be interested to know where/what the USA source for pine nuts is.
    I never had the bitter taste problem with pine nuts from China but apparently others have.
    I’m switching to other nuts for my pesto…actually I tried salted roasted cashews once when I was totally desperate-wow! talk about good.

    4:34 pm  Jun 17th, 2010
  552. carol

    I find that walnuts only are okay but the flavor isn’t as complex. The roasted quality of the pine nuts is what gives it such a nice flavor and it is the kind of nut that they use in Italy.

    4:37 pm  Jun 17th, 2010
  553. Laura

    We’ve been making pesto with cashew nuts instead of pine nuts. Since my experience not a single pine nut has passed my lips – I’ve picked them out of a couple of salads I ordered that didn’t mention they had pine nuts in them. I NEVER want to go through that again!

    5:01 pm  Jun 17th, 2010
  554. Samara

    Try making pesto with toasted pecans. Slightly toasting them brings out the flavor. I have also used walnuts but agree with Carol about the fullness of flavor. Both good, but I prefer the pecans. Will take her suggestion and try cashews next time. It’s been a week and the bitterness is leaving my tongue, but it is still sore and raw. Ouch.

  555. Nancy G/Olympia

    Now four days since I had the first handful of pine nuts. Had a second handful two days ago. No bad taste. Either the pine nuts are different this year or I’m different this year…. (bought them at the same store). Something’s different!!

    10:44 pm  Jun 20th, 2010

    Trader Joe’s near LAX has pulled the pine nuts off the shelves. Maybe all TJ’s have? Anyway we got our money back with lots of apologies. It has been 2 weeks and my mouth is still dry and somewhat metallic. My tongue soreness is finally going away so hopefully my tastebuds will be back to normal soon.

    I live in NJ, and purchased store brand pine nuts from my local Shop Rite for a recipe I made that night (Thursday). Symptoms appeared the next evening – the cherries I had been enjoying for several days tasted terrible. I chucked them out. Bitter and metallic taste continued all weekend, pizza tasted awful, white wine was like lighter fluid, and I was convinced I had some scary disease. Luckily I discovered what it was yesterday, I checked my packaging, it says MADE IN USA. I called my store and this morning the manufacturer returned my call, and he says the nuts came from China and I am the third person to complain about this and he wants a picture of the packaging b/c it’s incorrect.

    I called the FDA, they seem unconcerned, they say it’s allergies. B-S! I’ve been enoying pine nuts for years (usually in restaurants, I rarely buy them) and I’ve never had this problem.

    Gargling salt water before I eat seems to abate the bitter taste, but it comes back 10-15 minutes after I finish eating.

    Two times I have had the bad taste in my mouth. I didn’t realize unti the 2nd time that it was the damn PINE Nuts fromTraders. Beware Pine Nuts from Traders will do this. I went today and they are nut on the shelf anymore..

    I had never heard of this before until yesterday. Everything I ate was bitter, at first I thought it may have been a change in the oil used by the restaurant; but then EVERYTHING was bitter. I asked my sister-in-law if the food was bitter and she was experiencing the same thing, but not just about the restaurant’s food, but also everything. I ran some searches online and found some articles are pine nuts…bingo! We both had pine nuts one day prior. I buy pine nuts all the time and never had any problems until the last batch that I bought at Trader Joe’s. 🙁

    “pine nuts turn rancid quite quickly”. i guess i should have read this instead of eating a singe trader joe’s pine nut (probably 8 months old) two days ago, which has ruined all my food experiences today! thanks for solving my mystery though, i never would have guessed.

    Mystery solved! Thank you for posting this. Like many others here, I thought there was something wrong with me. I made pesto w/ pine nuts from Trader Joes, which I had stored in the freezer for several months. They tasted fine and I toasted them before putting them in the pesto. It took 3 days for the “Pine Mouth” symptoms to begin after eating the pesto. It’s now been 1-1/2 days that I’ve had this acrid taste on the back of my tongue. I will contact Trader Joes about this.

    So I just got a bag of mixed nuts, and decided to treat myself and got some Pine Nuts to add to the mix. I often bought Pine Nuts from Save-on-Foods with no problems, however this time I was shopping at The Great Canadian Superstore. Unfortunately they are known for poor quality goods, but I thought hey, they’re just nuts right? I have had this completely awful taste in my mouth for several days and will now be rinsing my mouth with vinegar, if not I’m going to go buy a Ginger root tomorrow!!!

    Thank goodness I found this, because i was starting to wonder what the heck was wrong with me. Everything tastes bitter and I’ve been sucking on Tic Tacs like crazy to try and combat it. I made pesto with Trader Joe’s pine nuts this past week, so I’m guessing that is the cause. I cannot wait for this horrid taste to go away.

    I’m in the UK and noticed the taste in my mouth right after a meal I made with pine nuts on Friday night. My friend who i also cooked for is fine though. I had also forgotten i had pine nuts in a restaurant salad Friday lunch, and in a Pret salad on Thursday, as well as Weds night having pesto and pine nuts in a meal… I don’t normally eat so many, although I’ve eaten them for years, but i hadn’t noticed I had been having them most of the week as it was in small doses here and there! By Saturday the aftertaste after eating was quite pronounced. It’s Day 3 (now Monday) and I think it’s diminishing slightly but it pretty foul. I got worried so Googled Bitter taste in mouth after eating and found this blog yesterday! I’m in Bristol in the UK and having called in on a couple of health food stores today to find a remedy, I found one of their staff had Pine Mouth a couple of weeks ago – but hers lasted 3 weeks! I hope it goes faster than that! Another shop served a lady recently too who tried Zinc for the Pine mouth taste disturbance as it’s supposed to balance out the taste buds or something.Not sure about that. I’m trying the Ginger remedy that Donna in Oregon above mentions – with root ginger, and also chewing on Crystallised Stem Ginger. Hope it works! Anyone with any other UK related incidents be interested to hear!

    Wow! I am SO happy to have found this site- I thought there was something wrong with me. I have been making pesto the past several days and using pine nuts- from China. I love pesto so much I can eat it with a spoon. I just called our co-op and they are going to look into this. I have never had this happen before- I am thankful for everyone’s comments!!

    Thank you so much ~ I started freaking out this afternoon after a few days of everything tasting so bitter and awful, and yes, I started eating Kirkland pinenuts purchased from Costco (produced in China) late last week. That must be it. You know, I never purchase any food items made in China anymore, but noticed the “product of China” label on the bag after eating some and thought “Oh, come on… a few pinenuts from China aren’t going to kill you.” Well, that’s it… NO more food purchases from China, period.

    Kristen, it’s not just the China pine nuts as you can see by all the posts. My China pine nuts were fine – it was the multi country Trader Joe;s nuts that got to a lot of us.

    I too am in the UK and relieved if not somewhat dismayed to find pine nuts being the culprit. I bought mine from Morrisons and they don’t specify a country of origin but I have never had a oine nut reaction until now. It was two days later when I had a sandwich from M&S which i thought was off, then a cup of tea which tasted bitter. Another cup of tea later led me to the assumption it was my brand of tea but then we went to dinner at a friend’s last night and her tea tasted bitter also. I was offered a glass of red wine which just compounded the problem and i concluded it must be tannin related. When i got home I googled my symptoms and discovered the pine nut problem. I am relieved in particular because I had cancer last year and during the chemotherapy was warned that a vile taste in the mouth could be a side effect. I was going to contact my oncologist until i came upon this blog and realised that those innocent looking nuts were the culprit. I haven’t found anything to relieve the symptoms but drinking water between mouthfulls of food seems to neutralise it temporarily. I am trying salted rice cakes which don’t seem too bad but have yet to find anything which doesn’t tast like it’d been doused in hairspray! I will try some extra strong chewing gum and post again if it turns out to have any benefits. Not sure if there is any point taking my pine nuts back to Morrisons but I will keep checking back on this site to see if anyone comes up with anything that might help

    To Sarah in UK, It is very important to take the pine nuts back to the store, even if you have no receipt. If everyone who had this problem made the connection, and returned the culprits to the store, there would be the beginning of awareness into how widespread this problem is. Also, I suggest reading through this blog’s archive. A few people had remedies. Ginger Tea worked for me. Recently someone was very positive about vinegar. If I ever find myself with pine nut disorder again, I will try the vinegar.
    (Wine and sugary foods tasted worst to me last November.)

    Adding Cosentino’s in San Jose to the list of grocery stores selling this “bitter” brand of pine nuts. I thought at $40/lb they could do better job in sorting them out.
    Bitter taste is really annoying, but… hey, on the bright side, already lost couple inches from my waist.
    Regarding antidote for biterness: Looks like the cream of asparagus soup relived symptoms for couple hours.

    Me too! Trader Joe’s purchased, freezer stored, but alas, the bitter mouth. I’m a dental hygienist and had an armory of horrible medical conditions dancing thru my head and began to worry about all the salmon i eat (mercury?) Boy, this site turned the light on! Thanks so much, i’ll try the vinegar, ginger, asparagus soup etc., and return the pine nuts.

    I just took a bag of pine nuts back to TJ’s, along with a printed article about “pine mouth”. The manager accepted the return, but said that the problem was only with nuts from China, and that is why that had not been available in the store for such a long time. My package listed the origin as Korea, Russia or Vietnam & I told the manager that they are definitely in the BAD category too. Now I have just read posts from A YEAR AGO from people who got pine mouth from TJ’s nuts from these exact same countries – NOT CHINA. How is this possible? I would be SO disappointed to have to QUIT SHOPPING AT TRADER JOE’S!!
    Are there any theories about why only certain people are affected? Could it be a blood-type thing? I’m O positive, for whatever it’s worth.
    I’m on day 3 of this nonsense, but I’m going to ignore the bitter taste of a cocktail now anyway…

    I had the EXACT same pine nuts as you from Trader Joes. “product of korea, russia or vietnam”
    The only thing that tastes vaguely normal is green tea. Sadly I can’t live off of it.
    Thanks for reporting this!

    Six months ago, I had “pine mouth” from pine nuts I purchased from Trader Joes. The package listed the origin as Korea, Russia or Vietnam. I had stored the nuts in my cupboard and they were open for about 4 months over the winter. Last week I found some pine nuts from Turkey at my super market. I took them home and ate two. The next day I was fine. I got up the courage to make some pesto. I had a large portion of pesto pasta with fresh basil from my garden, and guess what? NO “pine mouth”!!! From now on, I’m only going to eat pine nuts from Turkey and possibly Italy. I’m curious if others have had the same experience. I purchased the Turkish pine nuts from Market Basket in Westford, MA. They are made by Great Lakes International Trading Company and are called Mediterranean Pine nuts- $5.99 for 4 ounces.

    A while back I read that the nuts from Korea, Russia or Vietnam are really the Chinese variety of Pine Nut, but they are just packed in those other places.

    I have not eaten any pine nuts at all since last November.

    Man, I thought I was going crazy! I Googled “bitter taste in mouth” today, after almost two days of a bitter taste taste that gets worse when I eat or drink. This was one of the first things that came up, and I was astounded–we just had pine nuts on a home-made pizza the night before I noticed the taste. First time I’ve had pine nuts in months, maybe years, and this happens. They weren’t from Trader Joe’s, but they were from a similar style of market–I wonder what’s going on.

    Well, I’m super-relieved it’s not a tumor. I hope it goes away–my special weekend project was going to be making amaretto truffles, but I’ve been putting it off, because there’s not much point in making sweets if they’re going to taste like soap!

    OMG !!! I have had this terrible bitter taste in my mouth suddenly and would never have connected it to the pine nuts I had a few days ago. I never eat them so don’t have a history with them but thank you all !!

    pine nuts from the bulk bins at whole foods which I believe to be the culprit of bitter mouth for me. organic, but its hard telling where they r from. Im going to try the tomatoe juice as mentioned above, and see if its helpful.

    Wholefoods Dallas bulk bins here too. Made pesto and had a few handfuls and still have the taste 5 days later. So bizarre, I thought it was related to recently purchased vitamin D!

    I don’t think the issue here is rancidity. Usually you can tell when a nut is “off”. Does anyone know? From what I have heard it is just a different kind of pine nut.

  584. Nancy G/Olympia

    I agree with you Carol, I don’t think the issue is rancid nuts, but I don’t know what it is! Quantity consumed?? Other foods in combination with pine nuts??

    So I ate some pine nuts yesterday. At first I was like, “hey these pine nuts taste funny.” After looking at the packaged date, I realized it was because they were way too old to be eating. So I threw them away and thought nothing more of it. This morning I woke up with to this bitter taste in my mouth that wouldn’t go away. I’ve brushed my teeth like half a dozen times and rinsed my mouth out with mouth wash a few times. So obvisously I googled it and here I am. The issue definitely was that the nuts were rancid. Does anyone know how to get this taste out of my mouth??

    I posted earlier but I know it is difficult to filter through all the comments. However, this happened to a friend of mine and she got rid of the taste with vinegar. She rinsed her mouth several times using vinegar. Try it to see if it helps…..

    I have had this problem for three days and it was getting to the point this morning where I literally couldnt eat anything because of the bitterness afterwards. However, I think I might have finally beaten my tastebuds into submission with some seriously strong mouthwash, about ten of the sourest sweets I could find and not eating anything other than spicy food all day. It now seems almost back to normal already! Good luck to anyone else with this ailment, its truly horrible!!

    Today is the third date after eating pinenuts from Trader Joes. On Saturday, I made a nice roasted vegetable orzo salad with pinenuts as a topper. I noticed the bitter, sour taste in my mouth yesterday, and today it seems worse. Truly a bizarre experience, especially since I’ve been eating pinenuts for years. I’m bringing them back to TJs.

    I am so happy I found your blog as well! Couldn’t believe I wasn’t being a hypochondriac! I’ve never had a problem eating these nuts before- used to work in an Italian bakery and ate yummy pignoli cookies all the time and love them in salad.Guess there’s a first time for everything… Ate pine nuts in my salad on a Saturday and Sunday morning everything tasted horrible! Thought it was the cinnamon stick in my tea, but all day the taste was in the back of my throat. It’s been four days now and the bitterness is still there. Hope it’s gone soon!

    Thank god for the internet. I have, quite literally, been tearing my hair out. I had pine nuts following a health kick for the first time about four days ago. I made my husband try them – and he only had a few – and my 12 year old probably had 1 or 2. Admittedly, I substituted a meal for a bag of these nuts, but they have ruined my last week. Everything tastes bad, particularly after I eat anything, although it’s a bit better if I eat satsumas. Coffee tastes rancid, and dairy products; good god, vomit time. But, at least I know that my husband’s attempts at diagnosis were incorrect; we had cancer, pregnancy ( all of us, including him – and my 12 year old!) and various other things he’d never heard of. Thankfully, I’m on the satsumas and off the pinenuts …. forever. Cheers for the help.

    Thanks so much, this is my 4th bitter mouth day and I was starting to freak out. I did have pine nuts in a batch of pesto I made and the nuts were from Trader Joe’s. First time this has ever happened. I wish there was a way to neutralize the bitter taste but I’m glad it’s not something that will last forever.

    Curtis, regarding a previous post…The pine nuts from Trader Joe’s do come from China. I still have my bag and they did indeed come from China..They are just packaged in other countries. I submitted a detailed complaint to Trader Joes in June about this issue and why on earth they still carry the nuts. (they have rec’d numerous complaints ) Well no comment. I will no longer shop there as I must simply question their practice of quality control. Esp since most of the products they obtain come from other countries…and yes, CHINA! I am consciously trying not to purchase anything any further that says China on it as I question just how safe their products are..edible or not. And my pine nuts will soon be evaluated by the FDA. Ought to be interesting!

    5:56 pm  Jul 27th, 2010
  593. Pam in Sacramento

    Response to Cindy….The pine nuts Trader Joes say Russia, Korea and Vietnam are the countries they are packaged in, but I was told the actual nuts were obtained from China. And Sofia, if you still have your bag, please contact the FDA and send them the nuts. Companies will not stop importing these nuts until the FDA gets involved to find out exactly what is going on here. There are too many of us who have eaten pine nuts for 20-30 years and now suddenly are afflicted by these symptoms. Something is wrong!

    6:03 pm  Jul 27th, 2010
  594. carol

    When I took my bag back to TJ, the manager told me that the nuts were being evaluated by the FDA-but not because they were harmful to your health but because of “taste issues”. If you look at other posts when you Google: bitter taste pine nuts, there’s an interesting post about pine nut oil being used to curb the appetite.
    Sure, no one wants to eat when everything tastes bitter.

    You are doing God’s work here pilgrim. Thanks so much. It is pesto time here and basil grows like trees here in Tn. I usually buy from Whole Foods but was desperate the other day and bought from the local Megamart.

    The one concern I have, apart from the days of culinary wasteland, is that there are nasty molds associated with poor storeage of some such products. The mold that produces aflatoxin, nanogram for nanogram amongst the most potent toxins on Earth, were first associated with poor storage of peanuts.

    Anyway thanks, I thought I was going to need to cut back on alcohol.

    I had homemade pesto the other night and stored the leftovers in the fridge. I used some to spread on a sandwich, and while I was eating it, I was experiencing this “pine mouth.” I thought it was a bitter green pepper I was also eating, but it wasn’t. I thought eating something sweet would alleviate it, but no. Brushed teeth, gargled, and nothing helped. So, after reading all the entries on this site, I can also say my pine mouth came from Trader Joe’s pine nuts. Freshly purchased too, by the way. I will be reading the label to see where they came from before they are returned to the store.
    Italian pine nuts for me, or walnuts in the pesto next time!

    I’ve been eating pine nuts for days in various recipes as I use up the veggies and herbs in my garden and got gobsmacked with this yesterday. And just like everyone else I thought “brain tumor.” I’m not happy at the the thought of this lasting for days or weeks but on the bright side it’ll do wonders for my diet because nothing is appetizing right now. As for pesto, walnuts work very well for that. As someone says above, you’re doing God’s work here.

    I made pesto sauce with very expensive baby pine nuts from the local grocery store ($8.99 for a small plastic container). A day and a half later, my boyfriend and I both had metallic tastes in our mouths. After a google search, I learned it was the pine nuts. I notified the FDA and the grocery store. Everyone should notify the FDA so they can help regulate bad pine nuts.

    Thanks sooooo much for posting this. Last night I went out to a local bar with my boyfriend. I usually have the same drink, Bacardi O and Redbull. I took a sip of my drink and suddenly was shocked by a nasty after taste. I figured the owner cheaped out and got a less expensive energy drink so I didn’t complain and kept drinking the same drink. Fast forward to today, EVERYTHING tastes like I just walked into a cloud of hairspray with my mouth open. My stomach is a little upset, but that could be from the Bacardi. I googled “bad taste in back of mouth” and the first link my eyeballs flew to in horror was “pregnancy symptoms”. Now after reading this I feel a little silly for jumping the gun as I use pine nuts every time I make an Italian dish and I made one Wed. and was munching on a handful as I was cooking. I find it odd that my boyfriend ate them and had no reaction. Lucky me I guess! lol Good to know this isn’t some freak disorder though! Thanks!

    Thank you to everyone who is posting here! And thank you to the ones reporting pine nut issues to the FDA! More education will result in less unnecessary medical expenses and will hopefully put a kabosh on importing pine nuts from China unless there are much stricter guidelines. I am livid with Trader Joes not responding to complaints and still carrying these nuts on their shelves. Please, please keep reporting them if you have these symptoms. I as well as the rest of you never wish to experience this ordeal again! (unless you want to lose weight, hah!)

    I first experienced this with bulk pine nuts and from research on the web determined they were probably from China and processed in a way that was poisonous, as research pointed to this bitter taste reaction as a sign of being poisoned. May not be true, but I found that somewhere. So I did email the grocery store and let them know what happened as just an FYI, and I never heard from them. I too determined that I would only buy the more expensive ones in the jar, that I had previously purchased and not had any trouble with. Well, I recently had trouble with those too. It is day 3 of bitter taste for me. The first time my spouse experienced it too, but this time he did not, and I find that strange. Almost everything I eat now, tastes bitter. Also, the first time it lasted almost 2 weeks, so we will see how long it lasts this time. So if it is just bad pine nuts, or the way they are processed, I will be very cautious about using pine nuts anymore. I think it is time for me to substitute something else when pine nuts are called for. I hate that the bitter taste in my mouth spoils my morning coffee 🙁

    I am also a victim of the pine nuts syndrom. I ate a some pine nuts from Trader Joe. At 4 AM, I felt sick , and vomited what was left in my stomach. Apparently, I had not digested them well. I have had that bitter taste in my mouth for 3 days now, and I thought there was something really wrong with me.
    Thank you to all who posted. I am relieved this will eventually go away.
    I won’t eat another pine nut for the rest of my life.

    My “pine mouth” finally went away.. it lasted about a week. YAY! I did email Trader
    Joe’s about my episode, and even gave them this website. Here’s their response:

    “Hi Paula,

    We apologize for the experience you recently had with the Trader Joe’s
    Pignolias/Pine nuts purchased in our store. We appreciate you bringing
    your concerns to our attention, and for allowing us the opportunity to
    address them. What many of our customers have recently reported has been
    a naturally occuring situation with the pine nuts, and we assure you
    that it has nothing to do with where they are sourced from. However, our
    pine nuts do not come from China.

    The issue of the taste disturbance experienced after eating the pine
    nuts has been reported from several of our customers recently, as well
    as numerous other cases discussed with other retailer product. Generally
    what occurs (again, this is a naturally occurring phenomenon) after
    eating the pine nuts is that a bitter, metallic taste can develop 1-3
    days after consumption, and can last for days or weeks. However, while
    very unpleasant, it does not represent any health concern. It is also
    not linked to any sort of contamination, pesticides or heavy metals.
    Some of the pine nuts involved in some of the cases reported were from
    China, but this is not the case with all, and there is no conclusive
    link to any particular species or source country.

    Of course, we are offering our customers the option to return the item
    for exchange or refund, and our most sincere apologies (eventhough it is
    not as a result of any fault of ours–it’s nature!). Please know that we
    are currently selling through our remaining stock of this product and
    will not be reordering until the matter is resolved.

    Thank you,

    Nicki K.
    Trader Joe’s
    Customer Relations”

    So YAY Trader Joe’s for recognizing this problem and depleting their stock. But, they should also post a disclaimer above the product on the shelf stating the possibility of developing this bitter taste. But, I’ve eaten pine nuts for years, and this is the first problem I’ve ever had.

    Reply to Paula..
    Paula this is a canned repsonse from Trader Joes. I have read the exact same email from others. I have contacted them and asked them to give me the specifics on where the nuts came from. I also questioned them on a previous persons comment from them that they test their nuts. Um really? Where’s the report? And why no contact if they are so confident on the quality of the product? As for a natural occurence, don’t buy into that! I strongly believe there is a contamination on the
    pine nuts from China and with a lack of quality control, we really don’t know what we are consuming.
    I have been eating pine nuts for over 30 years now, since my teens and I have never experienced issues with Pine nuts until recently. Another person had researched the pine nuts packaged in the other countries incl Russia and Vietnam, and no surprise found they were still sourced from China.
    Trader Joes will not answer my specific questions I have addressed to them, because frankly they are not being honest with the consumer here.
    Until consumer affairs gets involved more seriously investigating this issue, I suggest no one eats pine nuts from Trader Joes. As for other institutions, I can not say as I have not been involved in any purchases from them.

    Just an fyi for you 🙂

    This is also the response that I received from England. Because no-one has been hospitalised or worse (!) they are saying there are no health risks. This has not been investigated, tested and therefore not proven.
    Interesting that Trader Joes say,
    ‘Please know that we are currently selling through our remaining stock of this product’. That’s good of them! At least they will get their money back – and no thoughts for the people who have yet to suffer this horrific experience. Many of whom will go through it, first thinking there is something seriously wrong with them and only relieved IF they happen to come to this site.
    As you say Pam, ‘I suggest no one eats pine nuts from Trader Joes’ – there needs to be some sort of warning given to people and if the traders don’t do it – maybe we should be contacting local newspapers or radio?!

    Oh, curse the Pine Nuts! Who would have guessed that a little crunch on my healthy salad was going to make me curse the darn things! I always keep my tree nuts in the freezer, so when I started having the bitter/metallic/sour taste a few days ago, I discounted the nuts and thought it might have been a rancid baking product. The power of Uncle Google, saved the day again.

    The response from Trader Joes is ridiculous. ” Although very unpleasant, it does not cause a health concern: what about a person’s well being, not being able to eat and losing weight. Those aren’t health concerns?

  609. Elaine (Derby UK)

    Exactly……………not being able to eat is the point – it’s not about being off your food or having no appetite! For me – I was scared to eat cos I knew what was going to happen. Being physically sick has also been mentioned by many including myself. That can’t be normal can it?!

    Reply to Elaine:
    Wow, your response from them really takes the cake! Until they can prove to the consumer, (which they can’t at this time), they are blowing smoke! Nausea, vomitting, bitter taste, weight loss, and worst of all medical expenses for people in a panic is completely unacceptable. They continually say its a natural occurence because they simply have no answers. And I told them I want the reports, the specifics, provide that to me. NO RESPONSE!! To me that says it all.

    I just feel for the people who wasted their monies making Dr and dental appts thinking they had a medical or dental issue. Should Trader Joe’s pay for those expenses? I dont consider visiting a medical professional a natural occurence related to the side effects of consuming TJ’s pine nuts.

    Once again, Please, please report them if you have had an issue and contact the Food and Drug administration. Continual complaints might finally wake someone up and start seriously investigating food consumption issues on products imported from China. Its been in toys, materials, electronicsl, etc. Why on earth wouldn’t food be a concern also? I’m just saying!

    And yes, local television will be the next step!

    This is a follow up for all of you poor people suffering right now. I am finally recovering from that awful bitter taste. It has taken 6 days. The 3rd day was the worst. I also suffered from nausea for 3 days.
    Ginger tea with honey helped the nausea. Peppermint tea with honey was the only thing still tasting good, so I drank a lot of it to flush out the poison. I do think we had symptoms of food poisoning. Those pine nuts are not fit for human consumption.
    Unfortunately, the FDA is not doing its job. They can’t even keep deadly supplements and drugs off the market or inspect fish and most imported foods. Check the cover story from Consumer Reports about that problem.

    Great relief to read the posts and will definitely try the ginger tea remedy tomorrow! Day three since eating some homemade basil and pine nut pesto. Fortunately my daughter is fine. Very interested to read future posts or info on more specific cause as not everyone consuming the offending nuts is affected so difficult to declare the batches faulty. Though no need to see GP now will mention it next visit to see how widespread info about the condition is amongst the medical profession.

    From wikipedia:

    Risks of eating pine nuts

    A small minority of pine nuts can cause taste disturbances, developing 1–3 days after consumption and lasting for days or weeks. A bitter, metallic taste is described. Though very unpleasant, there are no lasting effects. This phenomenon was first described in a scientific paper in 2001.[12] Some publications have made reference to this phenomenon as “pine mouth”.[13] This is a relatively new phenomenon which might be caused by the nuts spoiling and having gone rancid. It has been also hypothesized that this bitter side effect is caused by an allergy that some people may have to pine nuts, but this does not explain the recent appearance of this syndrome. Another theory attributes the phenomenon to nuts imported from China[14]. It has been hypothesized that the nut trees are absorbing something and passing it on to the nuts, or the nuts themselves are being treated with something before packaging. Metallic taste disturbance, known as metallogeusia, is reported 1–3 days after ingestion, being worse on day 2 and lasting for up to 2 weeks. Cases were self-limited and resolve without treatment.[15]

    My goodness! I am relieved to find a reason for this horrid taste in my mouth that has persisted now for 3 days. I ate about three tablespoons of pine nuts (purchased at TJs); they had come straight from my freezer. I’ve had this problem before, possibly coincidental with pine nut consumption in pesto. This time there was a clearer cause-effect because I ate alot of pine nuts. Hah! I thought it was my GERD acting up, so I took a Pepcid (even though I have no other symptoms).

    Same story, lasting 3-4 days for 3 of us who ate pine nuts from Trader Joe’s. It did seem that the price was suddenly much lower than in the past.
    Their explanation is rather feeble. Birth, death, and most illnesses are natural phenomenon but that doesn’t make illness and death any more acceptable for most people.
    The natural phenomenon seems likely that they are selling pine nuts that are not safe for consumption. The species of pine nut is likely inedible and not identified by picker, wholesaler, or Trader Joe’s. Since they look similar, the only way to know what you’re getting is to eat them and wait. Hopefully they will identify the edible strains and have an easy way to confirm the source by testing the nut batches. Until then “eater beware”.

    As I mentioned earlier, when I opened my bag of pine nuts I noticed a distinct piney smell that I had never smelled before. I also noticed the size and shape was different.

    Also, I didn’t feel good ( headache, a bit achy, tired) for a few days but it could have been coincidental. I do have a sensitivity to toxins that can brig about symptoms like this even if I am exposed to strong cleaners, perfumes, etc. The bitterness only lasted 3-4 days for me.

    I love you! I thought I was having a stroke (one that has lasted for two and a half days). Everything has an aftertaste, I decided was that of eating an orange rind. Turns out, I had a good part of a 1/2 cup of pine nuts I bought from my local co-op five days ago and have been eating in salads and two loaves of bread that I made with them.

    I have been feeling fine, otherwise. Now, it will go away, right? It is a total bummer to eat a fresh raspberry only to have it taste like orange rind!

    Strong ginger tea made with fresh sliced ginger pieces and ginger tea bags with some honey really helped. Symptoms greatly reduced next day which was day four. Back to normal taste buds day five! so hang in there future sufferers ..there is an end to this distasteful state of affairs!

    I am so relieved. I was just about to throw ot 4 litres of lamb/bean caserole because I had thought I’d overdone the Rosemary in it – making it bitter!!!!!

    For 3 days I attributed the vile bitter aftertaste and the bitter taste of everything I have been having to my head cold/sinuses …..but I have been eating and eating everything under the sun and the taste in my mouth wasnt improoving. It never occurred tha the vile taste of food and the bitter after-taste of everything I have been having may be due to the little pine-nuts….from our local Haris Farm Markets that I used for my homemade pesto

    From now on I will stick to the smaller stores which would be quickly made to change suppliers… if people worked it out that is…….

    It seems to me that there are enough people here that we could do a sort-of scientific analysis to determine what exactly causes this problem. We figured this out because everyone who suffered from it ate pine nuts. Maybe if we spell out the particulars, we can figure out other common denominators.

    I was the only one to experience this, even though there were about 8 people that ate with us. I did eat the most because I was the cook. I went back to the Co-op in St. Paul that I purchased the nuts from, and it says they came from Tierra Farm in New York ( There is no indication on the website where the nuts come from, but they claim to handle and sell only certified organic products. I get the feeling that the farm imports or buys them from somewhere else. I am in no way disparaging Tierra Farm. Really, I have no way of knowing for sure that the nuts really came from them – that is just what the sign said. We also don’t know whether they were old or what. They were refrigerated when I bought them and I used them the same day. Half were toasted and went in a salad. Half were toasted the next day and used in bread. I am on day 5 and the symptoms are fading.

    Thank goodness for GOOGLE! I googled “bitter taste in mouth” and this was the first link I clicked on and thank god I did, it just answered all my questions about what’s going on!!! I bought pine nuts from Whole Foods a few days ago (the kind that you can scoop out yourself). I started getting the bitter taste in my mouth the day after…but because I didn’t realize the culprit was pine nuts, I continued to eat them (little bit at a time). Since yesterday, I’ve stopped eating them and I feel that the bitterness is getting worse (I’m guessing it just get worse before it gets better)!!! I know there is light at the end of the tunnel at least! I called my local Whole Foods about this. The guy said I was the first one to report this but he was very apologetic and told me to return them for a refund. The pine nuts did come from China. He said he will report this to the buyers.
    I tried the ginger tea with honey and lemon as a previous poster mentioned…but it didn’t work for me!

    It has been a few weeks and the taste has gotten much better, it took about a week. I still get occasional bad taste in my mouth when I eat certain foods and when I brush my teeth. Found out the pine nuts came from China.

    Day 4…5 days after eating pine nuts on a salad at one of my favorite pizza places in St. Louis. I have talked to a few doctor friends and no one has ever heard of this before. I have eaten pine nuts before with no effect. This sucks. I will post back to detail duration.

    I am a recovered victim of pine nuts “pine mouth.” I am AMAZED at how many people have been afflicted with this, as I was. It took me about a week to ten days to feel free from that bitter taste. But, the other night, I had bruschetta, homemade, with homegrown tomatoes, basil (purchased from Trader Joe’s), garlic, balsamic vinegar & olive oil, and I nearly detected that same bitter taste. OH NO!! … Almost like the basil triggered it.
    Luckily, it was just that isolated incident, because it didn’t happen since (YAY!)
    I sent this website/blog address to Trader Joe’s with my original complaint. I wonder if their customer service is observing this site at all, or maintaining obliviousness (is that a word?)…
    I still shop at TJ’s though…. they are pretty much unsurpassed in many ways.

    Since last night I have had this awful bitter metallic taste in the back of my tongue/throat after I eat anything. I just discovered this site..I too ate pine nuts (from Whole Foods bin) with pesto, like two nights ago, then I had a few pine nuts yesterday. I was really worried something was wrong with me, so I called my dr. before seeing this site. I called Whole Foods..they said they hadn’t heard of any complaints, and that nuts get rancid. But the pine nuts tasted okay. I didn’t ask where their pine nuts came from. What is it in the nuts that is causing this? I have had plenty of pine nuts from Italy before, and I never experienced this symptom.

    I have this and I am miserable. Scheduled a doctors appt. unti I googlegled and found out it was the pine nuts from China that I ate in my pesto the other night, and scooped a couple of raw ones in my mouth. I can’t wait till the taste goes away… it is only day 1!

    Thank goodness for this website. This bitter taste occurred last month and lasted for a couple of days. Then yesterday it came back. Both times occurred around my “time of the month” so I thought maybe it was hormonal. Then I googled and I kept reading brain tumor, and since my grandfather died of brain cancer in his 30’s (and I don’t have health insurance), I was freaking out.

    Then I read about the pine nuts and bingo. I had them, from Trader Joe’s, a couple of days ago (and while we were cooking, I also ate a handful). Then I retraced, and yes, bingo, I had them last month, right before this taste first occurred.

    Whew, such a relief.

    I had this last month, starting 2 or 3 days after snacking on a couple handfuls of organic pine nuts I had just purchased from the Santa Monica Co-op. (So much for buying safe pine nuts at your local Co-op instead of large chains like TJ’s or Whole Foods or Costco!) The Co-op bulk guy put me in touch with the distributer, who said they were processed in China, but could have been grown in S. Korea, Mongolia, or China. I contacted the Co-op 10 days later to see if anyone else had reported a problem with this batch of pine nuts (newly in the bin just before I bought some) and they said I was the only one. I thought for sure there would be others. Mine lasted a week with slight bitter taste a few more days after that. Also had headache, nausea, and indigestion the first few days. I love pine nuts, so will take a chance on Italian or American if I can find some.

    Hello, I’m posting this from the UK. I’ve currently got ‘pine-mouth’ from eating pine nuts as part of a nut & seed pack from a well known large supermarket chain. I’m really glad I found these comments and worked this out as I thought I had something wrong with my digestion! In my case, I think the problem has been caused by the pine nuts going slightly rancid as the pack was right upto to it’s ‘use by’ date and I took a few days to eat them. Pine nut eaters beware – make sure they are fresh as the bitter taste will ruin your food for days! :o(

    Wow, I see I’m in good company. Bitter taste has haunted my every meal this Labor Day weekend. I was beginning to suspect some obscure allergy, when I googled and turned up your blog. Second time this summer it has happened–and yes, I snacked on a hefty serving of pine nuts while making pesto a couple nights ago. Organic, expensive, purchased at local Nat. Food store. No label of origin (I’ll blame China). Thanks for putting my mind at ease but putting me off pine nuts for a while.

    I was so happy to find this blog. I have been having the bitterness in my mouth for several days. And, yes, I have been eating pine nuts! I have a lot of basil growing in my garden, so I have been making pesto. And eating them raw, too. I will stop for awhile. This taste in my mouth is bugging me! Thank you again for the info!

    I googled “bitter taste in my mouth” and this blog came up. I’ve been suffering from the bitter taste in my mouth for two days. It makes most things I eat taste bitter, well I’m glad its nothing serious. My cause was pine nuts from the bulk in Jimbos health food store that I made with a rice pilaf. I’ve bought Costco ones before to make my Pesto and never had a problem, I think I’ll stick with them.

    I have the same problem. I was worried until I googled it. Unfortunately I ate some in a homemade pasta dinner and then ate some more the next day as well – before knowing what caused this metallic taste in my mouth. We eat pine nuts all the time and I have never had this happen. I bought my pine nuts at costco just this summer and they were kept in the refrigerator. I already threw away the package so I am not sure where they came from. This is such a bummer … can’t wait for it to end.

    Everyone has to make an effort to return the pine nuts to your store no matter how many were used, etc. The only way the stores will do anything about this is if it hurts them financially since they have determined this is not a health risk but a taste disruption. Take back your nuts and give the store this URL.

    So glad I found this blog as well as one other. I noticed the bitter taste in my mouth earlier today. I had eaten Trader Joe’s pine nuts mixed in with my green beans! And I went to a party the other night, had some wine and ate the pine nuts. I had a terrible headache the next day and didn’t think I had enough wine to give me a headache. I’m throwing out my pine nuts and emailing Trader Joe’s! Thanks for all your comments.

    Okay – I don’t know if this is related to the pine-mouth episode I experienced at the end of August, but about one week after that started, I was diagnosed with shingles. The doctor thought it was odd because it is usually something that occurs with older people who have suppressed immunity for some reason. I am neither old or immunity suppressed. Probably coincidental, but just wondering if it happened to anyone else, ’cause if the pine nuts are directly connected to shingles, that is a whole different kettle of fish. Trust me, it hurts!

    No shingles, but I do not feel well. headache, muscle fatigue, overall lethargy. I often get these symptoms my immune system is challenged in any way since having mono when I was a child.

    I am so shocked!!!! I was thinking that it was perhaps a medication that I was taking but I’m not taking anything new. I did eat a bowl of pine nuts a couple of days ago and I bought them at Trader Joes as well. This happened to me once before but didn’t think to google it… How annoying……everything REALLY tastes terrible and even without eating anything I have such a bitter awful taste….its been 3 days so I will look forward to getting rid of it soon. (I HOPE)

    This happened to me last year. I had purchased pine nuts for the first time as they were an ingredient in some recipe I was making. They tasted so good that I started munched on little bunches of them over the next couple of days. Then a day or two later the bitter taste came, and lasted 2 weeks, I’d say 1 week at full intensity and then gradually fading over the next week. They were purchased at Safeway, product of China.

    Day 5 and it’s no better 🙁 I’m from the UK and got mine from Tesco (from the baking section as they’re cheaper). I bloody love pine nuts, but right now, I don’t think I can ever buy them again, I’m so tired of everything tasting like it’s been marinated in petrol, nail varnish remover or cordosyl.

    Chip pinenuts has a lot of resin, can’t be desolved in water.
    Only aceton or organic solvent can do it. when you eat a lot of pinenuts we have coated our throut with resin and takes days to brush it of this stuff with food we concume

    I came across this blog about pine nuts and bitter taste while I was searching online for an explanation for my sudden bitter taste. Sure enough, I have been eating a lot of pine nuts with my salads recently, and the pine nuts come from Trader Joe’s. It’s one of my favorite stores, but I’ll never buy pine nuts there again!

    Wow! I googled “bad taste in my mouth” and found your blog. I have had a bitter taste in my mouth for the past few days and it’s driving me nuts. Everything from my toothpaste to crackers tastes different.

    On Saturday (three days ago) I made a pasta salad with pinenuts (or pignolias, as they call them), from Trader Joe’s. Now, I’m wondering if that’s where the taste came from.

    I also came down with what I thought was the 24 hour flu on Saturday night. Very sick for about 6 hours, without going into too much detail. It came on very suddenly, so I thought maybe it was food poisoning. But, I couldn’t think of anything I had eaten that would have been bad. Now, I’m wondering if it was the pinenuts. I paid $7.99 for that bag of pinenuts and hate to throw the rest away, but I don’t think I’ll risk it.

    How weird. Who knew?

    3:21 pm  Sep 27th, 2010
  649. Sher

    On second thought, now that I’ve read all the blogs, I’ll be returning what’s left of my bag to TJs and asking for a refund. They need to know that the problem continues. AND, I’m convinced now that what I thought was the flu was probably from the pinenuts after all. It will be awhile before I eat any pinenuts again. From anywhere!

    Unbelievable! I harvested all my basil yesterday and made 3 big batches of pesto using a large bag of pine nuts from Trader Joe’s. All the pesto went into the freezer but of course I munched on a few pine nuts as I was making it. By lunch time today I had this horrible bitter taste when I ate or drank anything. It is awful. I am furious that the pesto is not eatable and a complete waste. So glad I did not feed it to anyone else. I will be one very dissatisfied customer paying a visit to Trader Joe’s tomorrow. Thanks for info from everyone who has experienced this. I have never had this problem with pine nuts and have been using them in pesto for over 20 years (have always used Italian ones).

    Same thing here! Trader Joe’s pine nuts gave me major mouth-funk for at least a week. I told my husband what I’d read about pine nuts and this phenomenon, but he didn’t really believe me – until it happened to him too! I haven’t been brave enough to eat another pine nut since, and have started making my pesto with walnuts. Just as good, cheaper, and much less risky!

    I noticed the bitter taste this morning when drinking orange juice, and it continued all day. A couple of days ago, I made a dish containing pine nuts, which I bought at Trader Joe’s, and I had some yesterday. I’ve eaten pine nuts for years and this is the first time I’ve had this reaction. Usually, I get them at Costco, but there seems to be a shortage right now, and even the small bag at TJ’s was rather expensive. If the rest of my family has the same story, I’ll take them back to the store. They should be aware of this.

    I am also experiencing the dreaded “pine mouth syndrome” and it is absolutely atrocious! I purchased the nuts at my local Walmart so while I was there today I decided to compare a package that was from Turkey to the package that I had eaten two days prior and voila – the packages contained two VERY different looking pine nuts indeed! The ones that I had consumed were small with brown spots at the ends, while the Turkish pine nuts were longer and without any discoloration. At this point I’m wondering whether or not the offensive culprits we’ve been ingesting are even edible at all but instead are imposters that some companies are sneaking into the food supply for whatever reason. I plan on calling the FDA tomorrow to file a complaint, although I’m certainly not expecting very much, given their track record…..

    Phew! Knowing it’s from pine nuts is a relief. Made some pesto with pine nuts that I bought in bulk (paid $6.99/100g instead of $9.99/100grams at another store so thought I was getting a deal – will now spend the extra money) on Sunday. Didn’t suspect the pine nuts because the weird bitter chemical taste didn’t occur until Tuesday morning after a cup of coffee. I thought it was the coffee but it lasted all day no matter what I ate and has continued right on through today. I hope this taste it goes away soon. I have made a lot of pesto and still have quite a lot of pine nuts left. The weird thing is my husband is not experiencing this so I guess he’ll have to eat the rest of the pesto. I think I’m going to get him to return the pine nuts back to the store and inform them of this weird pine nut phenomenon.

    OK yes, I am officially a victim of the pinenut syndrome. I’ve had the bitter taste for 3 days now. I bought them @ Safeay, but they say China, Spain or Portugal. I will throw away the remainder of the nuts!

    So glad to find this! I ate a bunch of pine nuts and today my lunch was funny/bitter tasting (everything except the salmon), then at dinner my “on the sweet side” soup was bitter, and by the time I got to something sweet I was in full bitter mode. So far I know that salmon and camomille tea are working for me. Hope I’m one of those “few days” instead of “few weeks” people on this one. I threw away the bag so I’m not sure where they were from. I purchased them from Albertsons… they were in a small clear bag.

    I am a doctor myself and was asking various colleagues at work what to do- all set up for the full neurologic workup. Nice to know I don’t have a bain tumoir but this taste is HORRIBLE! I feel like I have a mouth full of pesticide.
    Headache too.
    I bought mine at Roche Brothers and the brand said specifically that they were from Greece.
    Mints seems to help a bit but I would love to actually eat something!!!!!

    I ordered a dish on Monday, October 4 from a restaurant that had pine nuts in it. Tuedays evening at dinner is when I noticed my chicken tasted very bitter. The next day my coffee tasted very bitter. I kept brushing my teeth and chewing gum. It seemed to get worse every day. I saw this on the internet about pine nuts and I was desperate to try anything to get rid of this awful taste in my mouth. I saw someone said that ginger helps. I bought Yogi ginger tea and drank a cup of it. I noticed the taste was gone. I was praying this worked. I ate a cracker (which tasted so horrible the day before) and sure enough it was better. I really think this ginger tea helped me!!! I hope any of you that are suffering from this can try this and see if it helps you. Good Luck! Six days of this terrible bitter taste is finally GONE! I will never eat another pine nut as long as I live!

    What a relief to know I don’t have some brain tumor! I had a beautiful dinner at a friend’s house last Friday evening and ate a lot of a salad containing pine nuts. On Saturday things didn’t taste terrible but not great either-I definitely detected that something was wrong with my taster. Then by Sunday the bitterness was clearly detectable and now, three days later, it’s really strong… and annoying. I’ve eaten pine nuts for years and this is the very first time I’ve experienced this. One blogger mentioned getting pine nuts from Italy instead of China (citing that the ones from Italy don’t have the problem). I think that’s what I’ll have to do because I love them but I cannot tolerate a recurrence of this. How long before it goes away?

    It took me almost 2 weeks to get rid of the bitter taste. It appears that pine nuts that are creamy colored and larger are OK – most everyone who has had a problem noticed that the nuts were smaller and darker.

  662. Diane

    Oh dear! Two weeks. Yuck. I’m going to try ginger tea as suggested by Joni. Thanks. I’ll let you know how it goes.

    What an enormous relief to find that this is so common! I too ate pinenuts on the weekeend and a few days later I felt the same symptoms and thought the worse. I mean what a drastic diet plan! I have found however that I have been able to enjoy eating custard with this problem. But thats all so far and tea without milk. I have eaten pine nuts for many years and have never had this problem. Its pretty horrible and I hope it goes away soon.Thanks to all the posters – there is comfort in shared misery.

    Ok, so it’s been 5½ days since I consumed the pine nuts and I’m (cautiously) thinking the bitter taste has passed. Yesterday afternoon I drank some ginger tea and now that I’m thinking about it, I don’t remember much more bitterness after that. Maybe a little last evening but not nearly what I’d been experiencing earlier in the day or the day before. And today I had a piece of toast and tea this a.m. and I’m it seems better. I’ll let you know if it comes back. Good luck all.

    Add my husband to the list of pine nut mouth victims. He made a huge batch of pesto a few days ago, using pine nuts purchased at Walmart. We’ve been eating it for 3 days, and today he started complaining that everything tasted bad. Thanks to the almighty Google, we now know why! Unfortunately, the nuts and packaging are long gone, so I can’t contact the FDA or the manufacturer. But I do recall that they looked different than the pine nuts I have purchased in the past; shorter and darker, with a dark spot on one end. I will definitely be checking the source from now on. And this just makes me more sure than ever that I will not be buying anything from China!

    My daughter came home from High School a few days ago and told me she “volunteered” to make a Pine Nut Tart for Latin class. I ran over to Trader Joes and purchased 2 – 8oz. bags of pine nuts ($7.99 ea.) and we started cooking. We used an assortment of nuts but primarily the pine nuts. About a day later, everything I tasted made me gag. However if I did not eat or drink anything, there was no problem. I immediately thought I had some virus and gargled with salt water. Ugggh! and no relief. I also came down with a slight eye infection which was eliminated with drops, but I think this may be an isolated incident. I have been searching for a quick fix but have not seen anything yet. Even though I like their stuff, I Will never buy pine nuts from Trader Joes.

    As always folks,
    PLEASE notify the store and when possible take back the packaging or partially used package and get your refund and complain. The only way these places will do something is if you hit them in the pocketbook. Also, if you don’t inform them they will never know there is a problem.

    I have experienced the exact same symptoms after eating pesto sauce I made from pine nuts I had in my freezer. I got them from Costco. I am still experiencing the symptoms (bitter taste when eating followed by slight nausea). I didn’t read all the entries but was reassured after seeing how many responses there are. I thought I had some rare endocrine disease. Will return my pine nuts to costco as suggested by carol..

    I just figured it out, via the google search ‘bitter taste pine nuts’, that pine nuts are most likely the culprit responsible for inflicting this unbearable bitter aftertaste via my tongue after EVERYTHING I eat. At this point the only thing I can enjoy are really strong vodka cocktails. I initially blamed the bitter aftertaste on dirty tap lines pouring bacterial laden draft beer I’d consumed at a divy bar, but when I went back to my fridge for leftovers, from the same dish containing the pine nuts, the bitter taste came back to me with a vengeance! I’m heading to the grocer I purchased the nuts from tomorrow to inform them of the predicament. Interesting how a search on the news sites yields next to nothing on this topic when there are obviously so many of us suffering from this.

    7:30 pm  Oct 17th, 2010
  671. Diane

    Yes, it is strange that it isn’t more widely known about. I’ve mentioned it to many friends, some of whom are doctors and nurses-no one has heard of it. Oddly though, others who ate the same thing I did haven’t experienced the same problem. So I’m wondering if it could be either; 1) having consumed one rancid or otherwise bad nut or 2) the volume of pine nuts consumed. I definitely had my fair share but no more than I’ve eaten on other occasions.

    Just so you know-it really did end completely by the 7th day.

    For the last four or five days, everything I eat or drink tastes bitter. I was beginning to get worried, so I googled about it and found this site. It can’t be a coincidence that I had purchased a bag of Trader Joe’s pine nuts last week and eaten some in a salad. They tasted fine at the time, by the way.

    11:43 am  Oct 18th, 2010
  673. Barb

    I stand corrected from my post on Oct 16: the pine nuts I bought were from whole foods. We were away when I discovered this website and when I got home I looked in my freezer and found the bag of pine nuts which I scooped from their open bin. I apologize Costco. Still having symptoms (6 days)

    just googled “bad taste in the mouth” and found out about pinenuts as a cause thanks to all of you so much glad to know it’s not stomach cancer i indeed had a whole bag of pinenuts a few days ago mine were bazzini’s from a&p

    I’ve also got the symptoms which just showed up this morning. My pine nuts were from trader joes, but the funny thing is that i’ve eaten half the bag already and this is the first time i’ve had the bitter taste. This is also the first time i’ve eaten them raw… on other occasions i have toasted them. I can’t decide if it’s just a coincidence or not.

    OMG! I’m so relived that I’m not the only one. I sure did went crazy checking online and found that “pine nuts” is the only reason why I’m having this bitter taste.
    It’s wired that if I’m not eating, I’m fine, but once I eat, then I can taste.
    Anyway, I had to comment because the pine nuts I got was from trader joe.

    11:37 am  Oct 20th, 2010
  677. Susan

    When I experienced the bitter taste, I too used Trader Joes pinenuts and did not toast them. I remember a Chinese American friend once mentioned to me that Americans cook with pinenuts in a different way than Chinese folks. Maybe the raw or under cooked nuts are part of the problem.

    4:08 pm  Oct 20th, 2010
  678. Chad

    Susan- Raw pine nuts had never caused a reaction like this with me before my recent ‘pine mouth’ episode. I’ve eaten raw pine nuts in pesto my entire life as well as on hummus and salads. There is something not right with these pine nuts I ate. I’m sending what pine nuts I have left over to the FDA and informing them of this situation. Not that I have much faith in the FDA’s ability to screen commercial food products, for various reasons, but at least hopefully I can do my part in making them privy to the inedible pine nuts currently on the market.

    pine mouth friends lol
    The pine nuts I bought from trader joes are toasted one and when I had it long time ago was raw but I toasted. (it was also from trader joes) I think it could be this particular brand from trader joes? I sent e-mail concerning about this to trader joes today.
    I will let everybody know when I receive reply back.
    My bitter taste is still there but it’s getting better…it’s been 3 days now…

    This is a really long list of comments to read but I have been following it ever since my husband and I experienced problems. We have since been doing a little personal investigation and it really does appear that you can spot the bad pine nuts before you buy them. Choose the pale creamy larger ones and do not eat the smaller brownish oily looking ones. One person who commented here said it had to do with the pine oil on the nut and I believe it!
    Eat the creamy colored nuts.
    Do NOT eat the brownish smaller variety.

    Pine Nuts from China (COSTCO brand do come from CHINA). No thank you.

    Also a burning sensation can be caused by CANOLA OIL. I had this experience
    with Artichokes (Kirkland COSTCO Brand) Packed in SPAIN… using CANOLA OIL..
    The Mediterranean is where Olive Oil comes from. I’ll pay the extra buck to have
    Olive Oil instead of Industrial Canola Oil used to package ingredients.

    Read the labels… very important to stay away from certain ingredients and also
    products coming from CHINA,

    We have very few gatekeepers in our Food & Safety Inspection departments.

    Share this information…

    Received this reply from Trader Joe’s today. Sounds like the solution is to buy your pine nuts somewhere else since they can’t find anything wrong with theirs. Which is strange, since this seems to have just started happening, and definitely didn’t happen to me in the past.
    Thank you for your feedback. We would like to extend our apologies for
    this unpleasant experience. We are aware that this has been an
    occurrence with some of our customers.

    This is not just an occurrence with Trader Joe’s brand or source, and
    not everyone reacts to the natural pine oils like this. Despite
    extensive testing by the FDA, other governmental agencies and our
    supplier, no conclusion has been reached as to why “Pine Mouth” occurs.
    Unfortunately, there are no quick remedies or preventive measure we can
    take to ensure it doesn’t happen again. Fortunately, all cases of
    pine-mouth resolve without treatment.

    There is no way to determine if this may occur with future batches.
    However, we can assure you that there are no pesticides used during the
    growth of pine nuts and there are no chemicals used in any processing of
    this product. We will be labeling our product with a disclaimer
    regarding the possibility of “Pine Mouth” for some customers.

    I also wanted to make sure you are aware of our “Product Guarantee.” If
    you are dissatisfied with any product purchased in our stores, you can
    take it back for an exchange or full refund. We stand behind our motto,
    “We tried it! We liked it! If you don’t, bring it back for a full
    refund, no questions asked.”

    Well add me to the list, for the past 24 hours everything tastes like poison, so I decide to look it up and found your post. Yep I JUST got a package of pine nuts from Trader Joes and have been enjoying them the past few days. GRRRR always something wrong with what I LIKE to eat. HEY maybe we are on to something, maybe a diet pill made out ot pine nuts that make food taste TERRIBLE will make you loose weight.

    Oh year! I’m dying! I ate pine nuts from Sam’s Club yesterday and all of a sudden when I went to eat dinner tonight (fast food with the kids), I was saying to them, “Does everything taste bitter to you? Maybe the oil was rancid”. But they said…”It tastes fine…sweet, savory….all was fine with them.” So I ignored it and kept driving to a scout event at REI. I got there and they had desserts. I popped some kind of cinnamon twirl in my mouth and argh….what the heck! It tasted like I was eating a dandelion. Then I followed it up with a sip of soda… And jiminy cricket…it was as bad as Yellow Dock! And Yellow Dock is just about the nastiest thing I have EVER tasted! When I got home I poured a glass of wine to disinfect my mouth and had to shudder after the first swig. Then I thought to myself..okay…I have mouth cancer…but before I go to the doctor, I am going to google what he’s going to tell me is wrong with me. Ha…Pine Nuts… So funny!

    How bizarre…the pine nuts did it for me too! Although, I don’t really get it because I bought them refrigerated and they went STRAIGHT in to my refrigerator at home. I bought them at PCC, which is a well-respected organic grocery store in the Northwest. They are from China, however, as you mentioned. My tongue also hurt after I ate them, so I wondered if I was allergic to them? Anyway, this is really funny, thanks so much for sharing your story with us. I’m going to stay away from pine nuts for awhile, I don’t like them enough to risk this happening again!!!

    Do NOT eat the brownish smaller variety.

    one person mentioned that there are no chemicals used in the processing so it is probably a pine oil residue on the nuts – thus the darker color. Maybe the smaller ones are just not ready to be harvested.

    I am so happy I found this thread. I ate a very small handful of pine nuts at a photoshoot two days ago. At the time I thought they tasted somewhat strange. Now I have the most horrible taste in my mouth as described every time I eat or drink. I’ve eaten pine nuts my whole life, mostly from domestic sources. I have no idea where the offensive (literally) pine nuts that I ate came from, but I am going to stay way from all varieties for a long time. I just hope my taste resolves itself before I go on a cruise in a few days. Imagine vacation with a horrible taste!

    Just wanted to let you know I risked cooking with pine nuts this past week. I purchased them from a small neighborhood shop. They were imported from Spain. And yes, they were a small fortune. But I had no problems whatsoever. I did look through and pick out any that weren’t beautiful. Like Zac, I’ve eaten pine nuts my whole life so it’s unlikely that I’ll stop….unless this happens a second time.

    I posted back in August..had pine mouth, then sent the leftover pine nuts to “Grace” (food scientist who posted) who is conducting a scientific investigation on this pine nut problem..she said that it’s believed the problem has to do with the type of tree (in China) that the pine nuts are being harvested from. If you have pine nuts left, send them to her, or e-mail her (she posted back in August I think).

    Thanks Geri, I also just sent mine to Grace. I am going on 3 weeks with the taste but it is getting better. Everyone on this blog should get a response to send theirs to Grace because most won’t read her comment. I also would like to know why the stores are still carrying the pine nuts. What is the FDA doing about it. Have you Geri, had any other side effects since last Aug. I am getting a lot of indigestion and wondered if it is related. I guess we can think everything is related. Can’t wait till it is totally over.

    Sorting the edible from inedible species will be a trick for a grocery shopper. Most of us were happy to get bargain pine nuts after paying dearly for them in the past but now we know the risk is real. I haven’t seen any liver function or other studies on those of us who have suffered from eating bad pine nuts, just comments that no sign of heavy metal poisoning have been identified. Since there is no guarantee that you will get edible ones I’ll be holding off on eating pine nuts for now. I have recently left New Mexico, where I learned to eat pinion pine nuts from my Navajo friends. I found it odd that there were numerous roadside Vans and Pick-ups selling pinion nuts now and there are only so many pinion pine trees from which they can be hand picked. I suspect that lots of these road side sellers have also outsourced to Asia. I look forward to the FDA entering this issue before the Republicans take away its funding

    Hi Barbara,

    I may have experienced some stomach problems as a result of eating the pine acid reflux I think.
    I’m being more careful now about what I buy in terms of where it comes from..seems that so much of what we eat or use comes from China.
    None of the stores seems to be addressing this issue much and yet so many people obviously are pine mouth sufferers..maybe some tv reporter should be making a report..
    It will be interesting to hear what Grace and other scientists discover, but it will take a while.

    I had this bitter aftertaste for over a week and was finally fed up with it and wanted to find out what was causing it. After I Googled it, and saw so many entries related to pine nuts I was relieved. Just so happens I purchased some pine nuts from Trader Joe’s just before this started. The package says they are from “either Russia or Korea”. I have notified Trader Joe’s so they are aware of the problem. I know they have had a number of recalls in the past so perhaps this is another product they should discontinue.

    Wow! This is interesting! All day yesterday (Sunday) I had this bitter taste. First, I made a green juice drink for my husband and myself and tasted it….it was so bitter. I thought I put too much green stuff in but my husband said it tasted fine. I made a smoothie for my kids and it tasted bitter too, but not to them….same story with everything I ate. I thought maybe I was detoxing. I’ve had metallic tastes in my mouth before when I’ve done a juice fast but this wasn’t metallic it was bitter and only when I ate. So, this morning (monday) the bitter taste is even stronger so decided to try to figure it out and came across the pine nut phenomenon. And sure enough, on Friday I had made a pesto with pine nuts that I bought from Krogers.

    OMG, this is happening to me right now. Made new recipe with roasted acorn squash and pine nuts on Saturday and today (Monday) I woke up with the worst taste in my mouth. I never eat pine nuts, so I am sure this is what is going on. I just hope it does not last for three weeks, since Thanksgiving is coming up! I guess it will be good for the diet!

    Bought pine nuts from local grocery bulk bin & made an Alfredo pasta dish with them on Saturday – four days ago. Five family members ate it, but only 8 year old daughter and myself are affected by this problem. Day four and we are getting better, but everything still tastes rather nasty. Think I may never eat pine nuts again – what a shame!

    Amazing – this blog has been going for a year & a half. Why are there no news stories about this? Why are stores and restaurants not more aware – or maybe they just need to care more?
    I ate mine in a salad at a middle eastern restaurant five days ago and the bitter taste is still strong. I am so thankful for this blog as like everyone else I was worried it indicated something much worse health wise. I plan to warn everyone I know about this now – we should all send out mass emails to our friends and this information circling on the web.

    This is crazy!!! Earlier this week I made a wild rice and pine nut stuffing with pine nuts purchased from Trader Joes’s. I haven’t been able to figure out the cause of the bitter taste in my mouth and just for the record chocolate doesn’t cure the issue. Gotta love googling. I wish you could recommend a remedy. I haven’t found one yet. Thanks for this write up.

    Yup, here in Melbourne, Australia same problem – I got some pine nuts from Coles – a larger-than-usual baggie and I’ve had this same foul bitter taste at the back of my mouth.. Went for a work trip to Sydney and it disappeared after 4-5 days..but now when I came back I had some more – and it’s back again! Good I read this post..Thanks for the info!

    THANK YOU!!!!!!! From the bottom of my heart, thank you for this posting. I was beginning to have serious concerns about my health due to the bitter taste at the back of my mouth for days. Being a chef it is NOT, I repeat: NOT desirable these last days up to Thanksgiving one of the most important meals of the year. BUT if it seems to go away with time, I suppose I will just be relieved that it wasn’t something worse. THANK YOU again for putting my worries at ease. Happy Thanksgiving to all, I suppose my sous chefs (family members) will have to do the tasting, as I currently have no way of doing it 🙁

    Got pine mouth and it lasted a total of 6 days. 2 days after eating pine nuts I got symptoms, symptoms lasted 4 days. The morning 6th morning I took an allegra (Like claritin) to see if it would stop it. Later that day it seemed to get better and better. I just dont know if it had run its course or it was the allegra – worth a try for you all – any over the counter allergy med would probably do.

    Easiest thing for me to eat was spicy foods and a fruity gum.

    Don’t worry – it goes away!

I actually had pinenuts from Trader Joe’s yesterday, lots of them so everything made sense. Thanks! I feel so much better right now just by knowing that this might be the reason and not a stomach problem.

    NO-ooo! I’ve got it again. I know I said I’d never have them again but ther were only a few in the pack of mixed pumpkin seeds sunflower seeds an pine nuts. I had some one day and foolishly did not wait to see but had more the next day and scattered on my rice. My husband only had a few and is fine. It’s not as bad as last time, but on day 5 and really looking forward to it going.
    I see that th Danish reckon it’s a different breed of pine tree that the Chinese are harvesting to keep up with demand.
    Must be a susceptibility factor too tho , maybe genetic cos plenty of us have unaffected friends and family.

    Moira, thank you for posting the link to the article about the Chinese varieties of nuts. It seems the Danes are taking this seriously.

    Have any of you noticed how it seems that this primarily affects females (at least if you look back on the postings here)? Many say that they (the women) are affected but not their husbands. It might make sense since women have been the gatherers since way back when, sometimes using taste to differentiate between edible and non-edible items.

    I also wonder if there is a way to identify pine nuts with more definitely than terms like large, white, brown, round, etc. (I may have to peruse some botany sites) If we can’t trust country of origin markings on packaging I’d like to find definite, verifiable sources of identification before I make my next pine nut purchase.

    Hello, I from Russia. The present pine nuts don’t have bitter taste. The cedar is very useful. In wood, where a cedar very pure air. In nuts many useful substances. It is possible to do milk of them. Cedar pitch well heals wounds, lifts immunity. As it is possible to do cedar oil. There can be you buy not qualitative pine nuts?

    I got the expensive pine nuts from Whole Foods, and this happened to me! I haven’t yet investigated where they come from (China, Italy, etc), but I am astonished that a store that takes such pride in quality, and that charges such high premiums for it, would sell me bad pine nuts. It’s been three days now and everything still tastes disgusting!

    Ok, I don’t know what Juliya is talking about but Zbuck, I’m with you. What I find astonishing is that nobody has ever heard of this problem….. except when I went into this tiny grocer on Arthur Avenue in the Bronx! It’s just this little, very long established family owned and operated specialty shop. I asked the shopkeeper where his pine nuts came from and he said they only buy them from Spain or Italy and that you have to make sure they are the long ones, not the rounder, smaller, oval nuts. They were $21.99/lb. but well worth it not to get pine mouth. With regard to Whole Foods, I think it has been established that they do a bit of baiting and switching with their customers. For instance, they are all about organic food but my understanding is that their prepared hot foods and salad bar aren’t organic, as one would presume they would be. I think they’ve made a name for themselves, people have come to count on it and now they’re capitalizing on it.

    This is the third time I have experienced this bitter taste phenomenon. Currently my diet is simple, so I can identify the source as (small) pine nuts (from China). I bought some miracle fruit in case I was inflicted again, but I can’t remember where I put them.

    I am JUST now experiencing this problem. I am overwhelmed at the bad taste in my mouth no matter what i eat. i ate pine nuts 2 days ago (which tasted just fine at the time) and the next day I started having issue with the metallic taste. it was thankfully the pharmacist who told me that this could be my issue. water is about the only thing i can handle. they say it can last as long as 4 weeks. i cannot get this “miracle fruit” everyone is describing. really do not care what kind of pine nut causes this. i just want a cure!

    I had pine mouth in November which lasted about 1 and 1/2 weeks with the bad taste progressively lessening. The only thing I found I could eat without a foul taste were the standard canned variety of black olives. Give them a try and see if it works. I did lose a little weight!

    I’m so relieved to read your blog on pine nuts being the cause of the bitterness! I was seriously ready to call my doctor. I recently started eating lots of pine nuts in my new favorite Arugula salad. My first episode lasted about 2 weeks – I thought it was from the mouthwash I started using. I quit using the mouthwash and the bitterness went away so I thought I’d figured it out – then I had my favorite salad again 2-3 days in a row and POW! The bitterness is back and prompted me to google the bitter taste again, and Pine Nuts jumped out – AHA MOMENT! My first back of pine nuts came from costco and were pretty old. My recently purchased bag was from Trader Joes. Thank you for posting – and my tastebuds thank you too!

    Earlier this evening I poured a whole bottle of wine down the sink thinking it had gone bad, and yesterday I was all in a huff because the fancy loaf of bread I bought tasted awful. After it occurred to me that these past three days in general were characterized by really bitter unpleasantness, I thought I’d better find out if I had some dread disease…and found pine nuts, thanks to you! Yes indeed, part of a bag of Trader Joe’s pine nuts went into a big salad I made for a party a few days ago and of course I nibbled on a handful or two while preparing the salad. ICK. Now I’m wondering if all those party guests are feeling gross too. Wow. I will definitely return the nuts to Trader Joe’s. Thanks for all the info.

    Wow. Thank the good Lord for Google. Just got back from a great time in Italy (Rome) and developed the disgusting taste you are all talking about. If the pine nuts from Italy are better, I wish the restaurant that I had dinner at my last night in Rome had not ordered theirs from China! I had a salad loaded with pine nuts. The next morning I felt nauseated, but that might have been from over indulging in everything that week. However, about a day in a half later the taste came. Yuck. My advice – no chocolate chip cookies – enjoy water with lemon – chew gum. Thanks, Nicole!

    I, too, amy so glad for Google. I thought I had a brain tumour, was pregnant AND had tooth decay! I eat pinenuts all the time and have never experienced this before. But sure enough, I made roasted broccoli with pine nuts the other night (a fabulous Barefoot Contessa recipe that you should check out) for Book Club and have been suffering the pine mouth since the day after. I just sent an e-mail to the girls in my Book Club to see if any of them have been affected. I will continue eating pine nuts but I think I might need a break for a little bit.Thanks for the info.

    Hey This is a good idea for dieting, consume some chinese pine nuts and your craving for food is gone since it will taste like shit. No wonder most of the chinese is skinny, they are consuming too much pine nuts over there and their love of food is gone.

    Have always enjoyed pine nuts until this happened to me this week. Mine were purchased in St. Louis @Schnuck’s. Brand new sealed 4 oz. Bag. Imported from China. Day 4 of nasty bitter mouth. Gross!

    I’m so happy to have run across this information. I, too, googled “bitter taste” and was baffled by the results. When I saw “pine nuts” out of the corner of my eye, I thought, “bingo”! Mine were from Trader Joe’s and, I must admit, they had been in my fridge for a while. I’m just relieved to hear that I may enjoy red wine again.

    GINGER PEPPERMINT TEA (HAPPY TUMMY BRAND FROM WHOLEFOODS) tastes delicious which in itself is amazing after four days of bitter taste after everything but water. Keeps bitter taste away until I eat something sweet like fruit. Also noted that spicy foods taste good compared to everything else.
    My pine nuts came from the local grocery store and were stored in the refridgerator for several months before i decided to taste a handful to see if they were still good. They tasted fine and i made a salad with some. Then developed the bitter taste the next day. i had used these same nuts several months ago the day i bought them with no bad taste. So, it may have something to do with how fresh they are as many people have suggested.

    I have had a bitter/metalic taste in my mouth and googled it. Over the past week I have been eating pine nuts from Trader Joes. I live only a few miles from pinion pines. I think I will do my own pine nut picking next season.

    I can´t hardly eat anything but I find out that I could eat my favourite chips called Cheez ringz from OLW…it´s rings done on corn…they don´t taste the same but I can´t feel the bitter taste behind it.

    I haven´t eaten pine nuts but it can be hidden somewhere in my food so I am worried that I will eat it over and over again.

    I am also this kind of person that I have hard to remember what I ate for 3 days ago….. I got pine mouth yesterday evening and go back to check the food is impossible but I never eat pine nuts in a bag.

  732. Nancy in Oly

    Eva, I don’t think you have to worry about hidden pine nuts in your food. Especially when you eat at a restaurant or at a fancy dinner. Most people don’t have pine nuts every day! Just make sure that next time you eat pine nuts they are fresh and not from China and it should be ok.

    1:20 pm  Feb 27th, 2011

    going out right now to get tomato juice. Both my husband and I have had the bitter taste for 2 days now. We both ate pine nuts from Trader Joe’s. Hope the TJ remedy works…really can’t stand much more of this.

    6:09 pm  Feb 27th, 2011
  734. Eva

    Nancy, I never eat outside my home so the pine nuts must be in some food inside my home.

    I bought home my ordinary things so I think it must come from oil that one have been cooked in at the factory.

    I don´t know if the pine mouth belong to that sign, that I started to cough and thought I had a flu so I am suspicion about the cough medicine I took before bed on Friday. It was a new cough medicine for me and it contains carob.

    Can carob cause the same reaction as pine nut ?

    6:44 pm  Feb 27th, 2011
  735. Nancy in Oly

    Eva, From what I’ve seen on this site all of us have had this horrible side effect after eating pine nuts and not from any other food. Some of us forgot or did not see the pine nuts, but in the end that is what it was.

    Pine nuts aren’t used to make oil that I know of. Neither is it an ingredient in the more common cold or cough medicines.

    I don’t know anything about carob or it’s properties other than that it is often used as a chocolate substitute.

    If you eat only at home with foods you have bought and prepared yourself you may have to start looking very closely at the ingredients in those foods for the last 2-4 days.

    There may be someone else on this web site who has more information.

    Good luck!

    Just wondering if Eva purchased a prepared pesto…
    I did a little research on pine nuts after this happened to me back in the fall. According to a local Italian grocer, the good nuts look different from the bad nuts. Look for the longer variety….they are quite long in comparison to the smaller, oval pine nuts. He also said he only buys from Spain or Italy. They are quite expensive ($21/lb) but I would pay almost anything to never experience pine mouth again. And the thing is, I really love pine nuts and use them in quite a few recipes. I have eaten the “good” pine nuts many times since and never had another episode.

    7:29 am  Feb 28th, 2011
  737. Eva

    I want to tell you that I live in Sweden so it have arrived here too.

    I love Pesto but haven´t eaten it in months.

    I wondering how strong this “poison” is ? Can it be so that a bad pine nut have been in a machine at the factory and after not clean out the machine so well have it infected the other food ?

    They don´t seem to be so much poison as it can be in a bag together with good nuts without people going sick.

    The Swedish FDA is now examining this with pine nuts and as soon I know something from here, I will tell you.

    It is all over the world now so soon do I think we will know a little more what this is and maybe the have a treatment for us.

    It´s the area close to my troat that am bitter. I can eat close to the front teeth and there is it not bitter but as soon I swallow what I eat, will it go very bitter.

    I feel like I have flu and in the morning did I had much fever. I don´t know if it´s belong to the pine mouth or if I have both a flu and pine mouth.

    Citrus like lemon and orange is impossible to eat as well sour cream and all kind that am sour.

    I ate fried fish and it tasted normal but the corn to it was awful bitter. It is interesting to see what I can eat and not….

    I know now that all sour doesn´t work. Candies taste less sugar.

    I don´t think Ice-cream works… ?

    I have had this bitter taste for 4 weeks now after having a salad with pine nuts from Turkey. I have undergone all possible tests to exclude disease, all normal. Obviously it is due to pine nuts, they are smaller and have a `dark head`.
    It persists in some individuals due to enterohepatic circulation, i.e. the liver detoxifies the toxin therein, which passes to the intestine where it may be reabsorbed and detoxified again in the liver, the latter excreting bile and giving the bitter taste.
    Will now try detoxifying the colon, one day no food together with 4 sachets of Klean Prep, used usually pre operations and pre endoscopy. The idea is to try and eliminate the toxin, and hopefully celebrating with a nice bottle of Barolo!

    Totally happened to me as well. Mine were from Trader joes. Not the worst things in the world, but definitely a left a horrible taste in my mouth for quite a while. Needless to say, I am going to be much more causious where I purchase my Pine Nuts.

    Thank you so much for this article!
    Me and my boyfriend have been going crazy trying to figure out what was causing this weird taste in the back of our mouths. We even through a box of cookies away because he thought there may have been some chemical on them. It hasn’t quite been a week since we had pine nuts that we bought from a local grocery store. Hopefully the taste goes away soon though 🙂

    Thanks A Million!!!

    Holy buckets! I was going crazy trying to figure out what has been causing this taste in my mouth since yesterday, and — of course — it’s the pine nuts I ate the other night. Mine were Trader Joe’s, too, purchased in St. Paul, MN. I made my husband pick up some peppermint gum on his way home tonight, and it’s helping a lot. I think my symptoms were already on the wane, though. Thanks for all the information. Nicole, what a great find your blog was.

    Thank you for your article. I also had a craving for pine nuts over the weekend. I bought them from Sainsburys a top UK supermarket, so I’m a bit shocked that they would be selling pine nuts that aren’t safe!! I don’t know how any supermarket or food store could do that… I just find it completely shocking. I don’t have allergies to nuts so I would have never imagined reacting in that way to them, especially as them seemed fresh etc.. I thought the bad aftertaste was related to my health and I was trying not to panic or book an expensive doctors appointment to have some mis-diagnosis etc and go round in circles etc… Phew!! … Anyway, thanks for the tip about peppermint gum!

    I ate some pine nuts from the Trader Joe’s in St. Louis 3 days ago. They were very small and looked different from any pine nuts I’d ever eaten. They tasted fine but I’ve had that bitter, metallic taste ever since (have also had GI symptoms). I’ve never had any issues with pine nuts before. Thank goodness I Googled it and found this site. I was getting ready to call my doctor! I’m returning the rest of the bag and will never get the small dark ones again. I love Trader Joe’s but i can’t believe they still sell them! Two years worth of posts and nothing has been done? Really?

    Hi Eva,
    Courage, I`m in my 6th week and still undergoing tests to make sure nothing is amiss. It came on 2 days after having pine nuts. Always hoping it will go off. I`m now submitting tests for heavy metals.I`m still waiting to have my Barolo.

    I purchased a small bag of pine nuts from Trader Joe’s a few days ago. I love them mixed with yogurt and blueberries. I had some last night and thought the berries must be bad and was not able to finish. Today my mouth tastes bad and now everything I eat is so bitter…even carrot juice and the plain yogurt I love so much. Water is the only welcome substance. Today I developed a sick headache, broke into a sweat and thought I would vomit. I did have some bowel distress. I managed to take a nap and the nausea has passed. I tried a small bowl of fresh plain yogurt, bananas, granola and pine nuts and the taste was so bad I had to throw it all out. This is the first such experience for me. I thought I must have developed some illness. All I can consume is water…my mouth tastes so foul!!! I am so glad to find the source may be pine nuts and that it may pass. Lousy way to loose weight!!! mark

    Even water brought on the bitterness for me so at least you can hydrate! It was six days for me which I think is sort of standard but I see where poor Marty is in his sixth WEEK! Ugh, poor Marty. Good luck.

    Hi Diane,
    Thanks for wishing me good luck, hope your wish comes through. My Barolo is still maturing! but I can have a sauvignon blanc, that`s not so bitter. I `m about to carry out tests for heavy metals. I`m taking 100mg of zinc daily to hopefully enhance regeneration of my taste buds??. The Chinese have issued a declaration about these pine nuts, they are inedible with unusual fatty acids.

    The bag is marked “Product of Russia or Korea”. I am amazed that so many people are experiencing the same problem. I feel so bad for those of you with long term persistent problems. I think this should be reported to the CPSC. I haven’t had pine nuts in years but I have always enjoyed them and never had any difficulties in the past. I wonder if we are all experiencing allergic reactions or are the nuts tainted? I’ll be visiting Trader Joe’s on Monday and will have some words. Has anyone made contact with any consumer agencies?

    The last time I was in Trader Joe’s, I told the manager about my experience with their pine nuts. He acted like he had never heard of the problem. He didn’t offer to research it and seemed to think I was a little crazy. He DID offer to give me another bag for free, but I said, NO WAY. My symptoms lasted about 10 days, so I feel lucky to have gotten over it. (The bag I checked also said Russia or Korea.) He said they have NOTHING from China.

    I am on my second month. 5 weeks with pine mouth so now do I think I maybe have something in my kitchen that have bad pine nuts in it ….. I maybe is hit once again with pine mouth.

    But also does it seems that my pinemouth is very strong because I have a light fever every day and sometimes am I so sleepy so I can sleep in 12 – 14 hours.

    I think my body react as it is in a allergy shock.

    It is not so very bitter anymore in my mouth or else am I use with it and ofcourse do I not eat things I know doesn´t work with pine-mouth…like sour food or drinks, oranges or ice-cream.

    Hi Eva,
    I`m a bit worried myself as it is too prolonged. I`m doing all kinds of tests, as that is part of my job. Probably some people react differently to these blessed Chinese pine nuts, no they are not blessed for sure. It`s annoying but I have to adapt. Will let you know of what happens with me, hope everything will turn out right. I`m a red wine drinker, which at present tastes awful, still waiting to tackle my Barolo.

    Today is Monday. On Saturday night I had a salad with pine nuts in it at a local restaurant. This morning the first thing I noticed was that my oatmeal tasted funny; I sort of brushed it aside. Then at lunch I had a tuna sandwich and it was awful and bitter, but I knew there was nothing wrong with it as I prepared it myself this morning. Then tonight I tried to eat chicken and broccoli and once again, all of it had a terrible aftertaste. My mind started racing, and I was actually considering whether it was possible to accidentally give onself cyanide poisoning with a bad bunch of almonds, whether I had developed a tumor or liver faiure, or what in the world was wrong with me. I googled “bitter taste in mouth” and came across this website. While I am relieved because I now believe I have determined the culprit, I cannot even begin to describe how angry this situation has made me. I have lost 45 pounds over the last year to get down to my ideal weight by eating a relatively clean and healthy diet, and I thought pine nuts were supposed to be good for you. I saw they were available and decided to try them. How can this condition be so common yet not widely discussed? This taste is truly awful and I cannot believe it may last as long as a few weeks. I am warning everyone I know to stay away from pine nuts both now and in the future. If this has been happening for 2 years why has no one done anything about it? Maybe it isn’t harmful but how do we know for certain? It certainly isn’t natural. I am going to try the V-8 / tomato juice cure and hopefully it will help.

    I developed a bitter, metallic taste that would be worse after consuming dairy products or fruit. After a couple days, I linked it to the pine nuts that I had been putting on my salads. I bought mine from Trader Joe’s in California. The same story as I’ve been reading. I ate mine as soon as I purchased them and stored them in the freezer. They were labeled, “Product of Korea or Russia.” So if they were rancid, they were that way when I bought them. They tasted fine. So I suspect that there may be chemicals on the pine nuts. I never had this problem with pine nuts from Italy.

    The only food I can eat now to avoid the awful bitter after taste is rice or bread. It has been 1 week since I last had pine nuts.

    Come on T.J.! Enough people have been complaining for several years now. Why doesn’t T.J. pull this product?

    Until somebody croaks from these nuts, none of the retailers or the FDA will take any action. Apparently it only affects a very small percentage of us and for most the effect “only” lasts for a week or two. The food business is low margin to start off with – why would they purchase higher-priced, better quality nuts when 99.9% can’t tell the difference?

    But fortunately from sites like this can we learn and figure out how to deal with it – look for “real” and fresh pine nuts, or when possible use alternatives like walnuts for pesto.

    Has anybody ever tried Miracle Fruit when affected? Miracle Fruit makes bitter food taste sweet. Sweet pesto has got to be better than bitter/metallic pesto.

    Good luck all!

    Thanks for this post… it was the first thing that came up when I searched for “bitter taste back of tongue”, and yep! I ate pine nuts from Trader Joe’s night before last. The bitter taste started yesterday afternoon, and everything tastes awful. I really hope this goes away quickly! :-/

    Add me to the list. I started getting the weird, nasty, bitter metallic taste at breakfast this morning, and couldn’t imagine what it was – thought my cottage cheese was bad. Since then, I haven’t been able to get rid of that taste. It’s worse when I’m actually eating or drinking, but never completely goes away. So I googled “bitter taste in mouth”, and immediately came across several articles about this “pine mouth” phenomenon. Sure enough, I had pine nuts on Saturday (2 days ago), for the first time in about a year. They were from Trader Joe’s.

    Hi Eva,
    Are you still having the bitter taste?. I`m still having it. I have just had a scan of my liver and gallbladder, all normal, today I have an appointment with the dentist to exclude that source, next a gastroscopy. I feel ok otherwise,but I miss my red wines.
    It is a shame on our standards boardes and our importers.

    I still have it and I have made now an appointment to my Doctor for her to really take care of it now.

    I start to be scared now because I don´t have only bitter taste but now have I also got like a creamy taste in my mouth like I eat butter.

    What I know is that I am very close to get diabetes because I have a little low of the blood salt and they have hard to stop my high bloodpressure.

    I don´t feel any special ill more than I get sometimes light fever.

    I am on my way to do some more blood test today.

    I had been to the cleaning of my teeth at my dentist when after I got this bitter in my mouth.

    Mary and Eva! Oh my gosh, I am so sorry that your pine nut mouth is not resolving. If it helps you to know, mine lasted a couple of months and some days I had a low grade fever and a little extra fatigue. I hate to hear that you are being subjected to a lot of “tests” that might be giving you radiation or in some other way have the possibility of adverse side effects. Marty, I think you are on to something about the possibility that you are allergic to the pine oil in the nuts. Wishing you both to return to full health soon.

    Hi Samara,
    Many thanks for your good wishes. Being a medical person and `pine mouth` is a recent new syndrome with very little solid proof, one starts thinking of other possible causes if it is prolonged. I even carried out tests for heavy metals, negative.
    One has to exclude other causes although my picture fitted well to what has been described here and at other sites. Physically I feel ok, I still jog etc. but once one is over sixty four , one is in a different bracket as far as health is concerned, so one comes to a conclusion of pine mouth by exclusion. Few medicals know about this syndrome. I think it is these specific inedible pine nuts[armandis] not an allergy to all pine nuts.

    I woke up this morning took my pills ate a bite of a bannana and got such a horrible bitter taste in the back of my mouth .. and i still have it.
    a day or 2 ago, I’m not positive i ate a handful of pine nuts. I love pine nuts but haven’t been eating them lately. I decided to google bitter aftertaste and found this website. I guess this Pine nut thing happened to me too. Who would have thought ! I hope it goes away soon because food does not taste good anymore.
    My pinenuts were from Shoprite. I had kept them refridgerated and the bag was still sealed but i probably should have thrown them away which sort of went thru my mind when i opened the bag.

    Joann, welcome (or not!) to the club. Mine has been quite a while ago but I remember it vividly. I totally lost my taste for food and lost almost 10 pounds! If you read some of the posts, you will find some people who tried different remedies. Hope you get over this sooner than I did – or at least hope you don’t mind losing a few pounds. Leave it up to me to look for the bright side.

    Hi Samara,
    Satisfy my curiosity, how long did your `pine mouth` persist? Mine now is over two months. If I tell you the amount of investigations and expenses I underwent, you would be surprised, I did them to exclude serious diseases. From blogs, I know of only two persons, besides myself, whose symptoms persisted for more than two months, Eva on this blog and another on Dr. Briffa`s blog.

    Marty, I literally had sores on my tongue for a couple of weeks. My “off” taste was a couple on months but it has been quite a while ago – a year and a half or so – so I can’t say exactly how long it lasted. I remember being concerned about the discolored spots on my tongue that were sore. i also had low grade fever off and on – indicative of allergic reaction I suppose. My lymph glands in my neck were somewhat enlarged. I eat very clean and am very aware of my reactions to food but am very hesitant to seek traditional medical “help” since it is rarely helpful or comes at such a high cost , no monetary so much as physical side effects etc. Above all – do no harm! I remember eating fresh chocolate mint from my garden and that gave me some temporary relief. I also made tea from it which tasted good when nothing else did. As we age we also heal slower, though my being so healthy I have always healed rather quickly – this was one exception. Sam

    Hi Samara,
    Thanks for your prompt reply. I do not have any lesions except for the bitter taste. It came on so suddenly. Being near Italy, we are fond of good food and obviously wine which I both cannot enjoy at present. On the other blog I told them I have a nice Barolo waiting for the day I can really enjoy it, hopefully it won`t be so long, although it doesn`t seem to be abating. Thanks anyway,it`s been nice blogging with you.

    Thank you! Now i know why i’ve been tasting that horrible bitter flavor at the back of my throat. I had pine nuts with my dinner two nights ago and again yesterday. Everything i put in my mouth since then has had a bitter after taste. I complained to everyone about this all day long and all i got was that it could be a sinus infection. Pine nuts were the culprit after all. Thanks for reassuring me. I was worried it may have been my liver or some other disease!

    Thank you all for your input. I just ate pine nuts two days in a row in a wonderful strawberry, red onion and spinach salad. My son, the chef, suggested adding pine nuts and goat cheese. Wonderful but now I have this nagging bitter taste in the back of my throat and when I googled it ..VOILA..Thank you all. I did get mine from Trader Joe’s, thinking I was saving money because at another store they were 14.99 for 3/4 of a pound and at Joe’s they were 7.99 for a half…what is a good price for these things? A safe price to know you are not paying too much ?

    I am going to call Trader Joe’s and tell them what happened. We will see if they listen. I love Trader JOe’s but they need to take these off the shelf if they are causing so many problems for people reporting it here..who knows how many others. This is a very informal poll.

    5:09 am  Apr 5th, 2011
  776. Diane

    We should all contact Trader Joe’s and let them know these pine nuts are a big problem. By the way, $14.99 isn’t bad for a lb. of the real pine nuts. I’ve paid over $20. But I’d pay almost anything not to have pine mouth again. Just so you know, you can tell the difference between the good and the bad nuts…small and oval are the bad ones and long and narrow are the good ones. Going forward I will only buy from small grocers who know where their pine nuts are from. I purchase mine on Arthur Ave. in the Bronx and the owner of the store told me he only buys pine nuts from Spain or Italy. He knew all about the bad nuts so if this tiny grocer knows about it, Trader Joe’s certainly must…but they choose to ignore it because they’re making a lot of money on cheap pine nuts. Plus it only affects a certain amount of the population so I’m sure they’ve done a market analysis to determine if they should continue to sell the bad nuts or take them off the market. As much as I love Trader Joe’s, let’s face it, they’ve gotten to be a big corporation, all the while looking like something very homey and humble. Sorry but my cynical side is showing. 🙂

    Has anyone filed a class-action lawsuit against the stores that carry these nasty pine-nuts? The so-called experts say there are no lasting effects, but I keep inhaling (aspirating) the bile my stomach churns up and I am fairly certain that since the nuts have been repeatedly tested and show no metals in them, that the real cause of the metallic taste is, in fact, the effect of irritating the body to the point of bleeding in minute amounts in the throat, tongue, nasal and respiratory passages. (I know I can see three irritated patches on the back of my tongue closest to the throat). This means many of us sufferers would be at higher risk for contracting airborne and other illnesses such as STDs (yes, the S is still in there even if it is “just oral”). What secondary infections and lasting residuals are we being exposed to here? It angers me to see so many others having suffered after purchasing from Trader Joe’s and Whole Foods — those are where I always shop and where I bought mine! I didn’t have to suffer! They could have prevented this!!

    Hi All,

    I decided to contact Trader Joe’s, so I thought I’d share the response I got. It’s obvious they are aware of it but unwilling to take the product off the shelf. It sounds like they’re going to sell out of it and not reorder until “the matter is resolved”. Yet they claim “it’s nature”. They say the nuts are not from China but don’t tell where they’re from. Anyway, here it is:


    We apologize for the experience you recently had with the Trader Joe’s
    Pignolias/Pine nuts purchased in our store. We appreciate you bringing
    your concerns to our attention, and for allowing us the opportunity to
    address them. What many of our customers have recently reported has been
    a naturally occurring situation with the pine nuts, and we assure you
    that it has nothing to do with where they are sourced from. However, our
    pine nuts do not come from China.

    The issue of the taste disturbance experienced after eating the pine
    nuts has been reported from several of our customers recently, as well
    as numerous other cases discussed with other retailer product. Generally
    what occurs (again, this is a naturally occurring phenomenon) after
    eating the pine nuts is that a bitter, metallic taste can develop 1-3
    days after consumption, and can last for days or weeks. However, while
    very unpleasant, it does not represent any health concern. It is also
    not linked to any sort of contamination, pesticides or heavy metals.
    Some of the pine nuts involved in some of the cases reported were from
    China, but this is not the case with all, and there is no conclusive
    link to any particular species or source country.

    Of course, we are offering our customers the option to return the item
    for exchange or refund, and our most sincere apologies (even though it
    is not as a result of any fault of ours–it’s nature!). Please know that
    we are currently selling through our remaining stock of this product and
    will not be reordering until the matter is resolved.

    Oh blimey! Go back to last year – this is a bog-standard letter that ha been sent out at least three times to my knowledge! So they obviously ARE re-ordering and continuing to sell……’s a ploy to make people think they care enough to do anything about it. Maybe every manager should be made to eat a packetfull and see what happends? This is so annoying.

    1:37 pm  Apr 6th, 2011
  780. Diane

    Great idea! We should each go to our local Trader Joe’s and force feed the manager a bag of pine nuts. Unfortunately not every manager would be affected but certainly a few would be. Actually, no, I wouldn’t wish this on my worst enemy. It’s also not their fault but the higher-ups might listen if a manager were to complain.

    Hi all,
    I just want to point out that the pine nuts i purchased were not from Trader Joe’s. I got them from a supermarket chain. I forgot the name of the brand. Maybe it was Natural Products. I will check when i go back there this week. This is the second time i got pine mouth. I did not know the cause the first time i experienced pine mouth. I though the bitter taste was due to an oncoming sinus infection in my tonsils or something. It was disgusted bitter taste in my mouth that lasted 5 days.
    I only found out about “pine mouth” when i came to this site after getting it last week. It lasted 5 days again. Seriously, i never want to eat pine nuts again for fear of getting pine mouth again. My husband was never affected both times. I come from the Middle East and my parents always buy pine nuts from a store where you can taste them for freshness first. My mother also told me to make sure the pine nuts do not have any dark specks on them and to buy in small quantities as they go rancid fast and to keep them stored in the fridge to prevent them from going bad. In the US, most stores have these pine nuts sitting on shelves for weeks on end! It increases the probability of some going rancid. Hope this helps.
    All i can say is thankfully that bitter taste has gone.

    I have started to eat Zinc and it seems it works !

    I think I had to little zinc in me. I have not checked with a Doctor but I can feel it inside me.

    This is my theory only but worth a trial.

    Before I started with zinc was I vomit because my stomach was so extream changed and was more based …… I have very acid stomach and eat medicine since the 80´s

    mouth react most on sour products so I think it have been a change in the Ph for us with long lasting pinemouth.

    We also experienced this problem after consuming pine nuts (Homa brand from China in produce section exp. date 1/12) ground up in homemade pesto. This off taste continued for a week. Then we once again had the problem with aftertaste of rotten pecans after eating Near East Couscous mix with toasted pine nuts about a week later. We’ve had the couscous many times before without any problem. I wonder if the amount digested the first time in the pesto brought on the second reaction with the couscous that had far less pine nuts in the mix? I’ve now tried drinking the V-8 to help rid the awful taste. Thank you for this post and bringing it to the average person.

    What an A-HA this post was! I purchased Pine Nuts at Target, I was eating them while doing yard work, shortly after my esophagus started to contstrict with painful contractions every minute or so, I rushed inside and popped 3 benadryl, within 1 hour I was better but that’s one heck of a way to find out you are allergic to something! I believe the physical exertion of yard work accelerated and magnified the symptoms.

    Now for 3 days everything I eat and drink gives me a bitter, chemical/metallic taste in my mouth/tongue that won’t go away, I brush my teeth and tongue to get temporary relief, but as soon as I eat or drink anything it comes right back. Dairy products like yogurt seem to taste somwhat normal…but this is terrible, I will never again eat pine nuts…especially from target!!!

    Again, i’m glad someone explained this to everyone else. I agree! Look at all those hits and posts!

    Hi Eva,
    I`m very sorry that you ended up with diabetes. Do not lose heart, with diet , exercise and medication you can easily control it, check your eyes yearly, take care of your feet and check urine for albumin regularly. I checked my sugar 2 months ago, it was ok, will do so again. I`ll be doing a gastroscopy to exclude anything serious, that would have covered almost all systems. That pine nut salad has caused me a lot of anguish and expenses, although I`m well insured. I wish you a speedy recovery.

    Hi Marty,

    I have taken my first medicine pill against diabetes and I am curious if the medicine I got today will help me with my bad mouth.

    I have got potassium too.

    I think it is a blessing to have got a light diabetes because I really understand how important it is to lower my weight and really take care of myself.

    Today did I start on a gymn and the membership is only 50% because I need exercise against my diabetes…

    Here in Sweden do we have almost free Doctor and medicine so it´s not an economic problem to have diabetes and in that way can I ask my Doctor to test things to find out what´s wrong….. I have some bloodtests going on to check out where the bitter taste are coming from.

    I will tell if my bitter taste in mouth is really gone….. I hate to pay for nice food that taste like eating aliens ….. 3 months is it now with this taste in my mouth even the salvia taste bitter many times….

    Hi Eva,
    I have undergone a gastroscopy to exclude any serious disease. Now I have practically investigated every system thoroughly except an MRI of the brain. I still have this bitter metallic taste which I can now presume it is from the pine nuts, why the symptoms persist I do not know. All I know is I cannot enjoy my food and red wine.Hope this bitterness subsides.

    Hi Marty,

    it have not left me either but I am used with it and accept that my food taste different nowdays but I should never buy expencive food or wine with this bitter and creamy taste.

    I have taken medicine for diabetes now in some days but it have not going any better.

    When it happen that the bitter taste come had I been to my dentist and they had cleaning up my teeth and I was ill for maybe 4 days like the dentist had going down too deep in her cleaning. She didn´t use the drill, she did it manual and I was sour for 4 days.

    Have you checked with the dentist ? That´s my most thinking it could be…something with the teeth

    Hi Eva,
    I have been to the ENT people, dentist, I had 4 liver function tests, tumor markers, CRP,ESR, test for heavy metals, a liver scan, a gastroscopy, diabetes tests,the only test I have not had is an MRI of the brain. I`m a doctor [ GP and for the last 20 years working in geriatric medicine], so I can investigate myself more easily.When I get fed up I will contact one of my neurology colleagues. I presume it is from the pine nuts but it is not documented that it lasts so long,3 months. At present I`m on Bragg`s activated charcoal tablets, I almost finished 100 tabs. with no positive result. I keep on hoping. I miss my fish and red wines.

    I have hope in you that you will help me to find the soloution for me too…..

    In my genes do I have cooking skills and it is a catastroph for me to could not enjoy my food anymore.

    I have not tasted wine but I drink coke with a little Rum in it and it taste ok … I think I have been used with the taste now after 3 months because I can eat food without no problems.

    I eat light food and fish is very much in my diet but it taste ok now in Easter do I eat smoked salomon and egg and it´s ok.

    I think I am used with the strange taste now and when my stomach be bad and I feel like I am poisoned do I take those expencive chew gums that I have talked about before and it calm down a little.

    Now when I have diabetes will I get more tests so maybe we find the answer from here ?

    I suppose it will be shock that day when my salivia will be sweet again and not bitter. I hope it doesn´t damage the teeth.

    I have read that they use pinenuts-oil in food too so it doesn´t need to be visible pine-nuts people eat.

    Hi Eva,
    You are lucky you can have your salmon, I cannot have fresh salmon or tuna they make my `pine mouth` worse, same with red wine it tastes metallic, I`m on to white wine, I find sauvignon blanc best as it is acidic.I may disappoint you as I haven`t found a solution myself, I`m always hoping there is nothing serious. I even tried colonic detoxification, hoping to eliminate the toxin, it`s exactly bowel preparation for operation, no food for 24 hrs+ 4 liters with that horrible Klean Prep, it`s awful. Will keep you posted if I find a solution or I find what`s causing it.

I’ve been following this blog since 2010 so I never saw the original Pine Nuts/Trader Joes article but when I was googling my crazy symptoms this post popped up.

    Hello, just for everyone in England, I bought some last week in the Sainsbury’s. I will have to write them an e-mail. The PNS really is not a nice experience. I really was worried. Before I was buying only organic once and they were fine (Not sure about the origins.). I read on some other web that avoiding milk, coffee and very fatty food should help you to get over it sooner??? I will try.

    Hi Eva,
    As promised I`ll keep you posted. I did my gastroscopy, was found to have a chronic gastritis and I took a triple therapy course + PPIs even though I was free of any H. pylori infections. Initially my bitterness was subsiding I thought, I was on a long flight on Emirates & I could not resist their fine red wines in 1st. That got me going on to red wines and gradually the bitterness started creeping in again. I`m still having activated charcoal tablets for all it`s worth. I hope the toxin in the pine nuts has not damaged my glossopharyngeal nerve. If it persists I`ll have to see a neurologist.

    Thank you Marty for the update !

    I think I have been used with the bad taste so I don´t feel like it hopeless. I have start eating zink and I will tell you and you other if zink it´s what is missing in us that am almost sure that we have not eating pine nuts.

    It is the same problem as pine nut eater so we will solve this together. I hope you don´t hide if you know how to could stop it.

    I can eat some of the ice-cream that I couldn´t eat before. I ate a mango ice-cream made by muslims so they mybe use another sort of sugar and it tasted ok and I buy sugar free ice-cream and it taste great.

    Whipped cream and normal ice-cream doesn´t work.

    Either is it the medicine for diabetes, more healthy eating that make me could eat more of the food I couldn´t eat before but I am not free yet from the bitter taste.

    Sometimes do I get more bitter taste in my salivia, it is like it is a war in my body and I believe it is like Marty saying that we have got poison in our bodies and maybe I have eating the same poison even if I didn´t ate pine nuts in February 2011.

    I also will update because I haven´t give up to solve this issue and I have free Doctors and medicine until September so I will nagging my family Doctor.

    Where I live, Sweden, do we have one of the worlds best medicine researcher and export of medicines so it can happen that they will solve it here…..

    the problem is that we are so few in our country ( only 9 million ) so it can take time before the Doctors understand that it is a huge problem with pine mouth or it can happen they get an order to solve it from other countries.

    I have heard that some people have complained about pine mouth in those health stores I have been in and we eat much pine nuts here in pesto and as snacks.

    Hi Eva,
    I have tried zinc, but it may have made it worse. You can try a zinc solution if it gives you a metallic taste it means you do not need any supplements. I still blame the pine nuts and the Chinese who exported them. I`m a crusher and have not stopped eating or drinking wine, being a Mediterranean, but the finish is bitter so I cannot enjoy the good taste [finish] and appreciate the wines. Thank God I`m not a chef as I would run a restaurant to the ground. We keep hoping to regain normality. Ciao.

    Yes! Also couldn’t figure out! Ate pine nuts (from Trader Joe’s) on a salad (yesterday a.m. – another “breakfast of champions”) and have experienced “yucky taste in mouth when eating” – the exact search parameter that came to your site FIRST. Thanks for helping this “internet-obsessed hypochondriac.”

    PS – should I just toss the bag? (they’re so stinking expensive!)

    Awesome! I thought I had internal bleeding or something weird going on with my body, but I’ve been snacking on pine nuts everyday this week…! I thought it was so strange… Thank you!

    thank you so much for posting this…
    made delicious pasta last night with pine nuts from TRADER JOE’S!!!
    woke up to eat what seemed to be delicious watermelon and then suddenly tasted the metal…hmmm bad watermelon from Mexico we decided…from then on everything we ate, same metallic taste…did some research online and learned of metal mouth from pine nuts! UNBELIEVABLE! Looked at the bag to find they are from Korea, Vietnam, or Russia…only ITALIAN from now on!!!!
    Trader Joes needs to find a different supplier!
    Thank God for the internet or I’m sure we’d think we had some bizarre disease!

    It’s crazy but your story sounds exactly the same as mine, right down to the chili for breakfast. I googled looking for an answer to my bitter mouth and found this. I also have been eating pine nuts and just looked at the bag and they are from China. Thank you for writing this, it has put me at ease.

    Hello everyone,
    I will explain what happened to me regarding pine nuts “aka horror nuts!” shortly, but I wanted to start with what HELPED with my “pine mouth” because as soon as I discovered this awful reaction, I searched desperatly for anything at all to help me.

    Okay, so these are the things that helped with the symptoms, I know these may not help everyone, but its worth a try. I found the most helpful thing to be anything lemony, mainly Lemon Sherbet sweets, which I would suck on constantly, they seemed strong enough to slightly mask the horrific taste of chemicals, as soon as I finished the sweet however, the awful taste would come back, but at least there was some relief. I found pretty much ALL drinks would still taste of chemicals, so I would try to drink a good glass of water and then have something lemony. I have had serious sugar overload the past few days, with all the lemon sweets I have been sucking, but its definatly worth it 🙂 I tried several different types of sweets, with varying flavours, I sent my fiance to the shop with the instruction to buy ANYTHING with a strong flavour, I found mint things to be the WORST, this seemed to highten the chemical taste. Lemon seems to be the way forward.

    I don’t want to bore everyone with my story really because I know it will pretty much mirror all the others, but I will give a brief outline……..I have a serious medical condition anyway and thought the awfyl chemical taste was down to that, I becamereally concerned. Not sure if anyone else felt the same way, but you start to question if you are over reacting! Because its so bad, but sounds so crazy to be moaning on about a horrific taste, but it really is HORRIFIC! Not realising that the cause was Pesto (pine nut based) I carried on eating it for a few days before discovering what was causing my problem. I can honestly say, this is an awful thing, it feels like having hairspray sprayed into your mouth constantly, I wanted to heave all the time. It kept me awake at night, because my brain was obviously telling me I was going to be sick all the time. I cant believe this isnt a well known thing?! Why dont people know about it?!

    Anyway, I am not on day 7 of “pesto gate” and I am a little better, although I am nervous to type that because as soon as I think the taste is subsiding, it seems to resurface. Its worse in the morning……but sucking on anything with a strong lemon flavour definatly helped me, I really hope this helps someone, because I was really suffering at 4am the other night and wanted to cry because I couldnt think of anything to try.

    If anyone wants to comment me back, I have activated comment back to my email so I will beable to reply.

    This is terrible. Thank god I found this site. As everyone else here, I, too, ate raw pine nuts (as per recent Dr. Oz show tip) and now have this horrendous taste in mouth. It is, as others have described, a bitter taste, cross between an asprin melting, metal and hairspray! So upset. I reported to FDA and Giant Eagle grocery store where I purchased them. AND yes, they are from China! Anyone found anything that really helps? I’m going to try lemons, and ginger chews, and maybe vinegar. It appears that this thread has been running for a couple of years. Why have these pine nuts not been pulled from stores or why do we keep importing them from bad sources??

    Just got back from Italy and now now why few suppliers are carrying Italian pine nuts which do not cause the bitter taste. They are so expensive-like 35 euro per kilo?
    So, of course places like Trader Joes tries to keep the cost down.
    I bought some precious Italian pine nuts and will savor them….. like gold.

    Thank you! Thank you! I made a salad Sunday night with pine nuts and the symptoms started the day after… Bitter everything! Sure enough, Trader Joe’s pine nuts. My entire family was concerned it was something more serious! Thanks for the relief!

    Thank you! I was beginning to worry. I made fresh pesto the other day with basil I grow on the back porch–my first time! I was so proud of myself. Two days later, I can’t eat anything without a terrible bitter taste in my mouth. I went to Trader Joes to purchase my pine nuts, thinking they would be “healthier.” I haven’t bought pine nuts in years, so when I saw the $7.99 price I was stunned. I will definitly be getting that back. I wanted to lose weight. Maybe I’ll take advantage of this situation. Thanks again for your thorough report on “potty mouth.”

    I just bought Trader Joe Pine Nuts will be bringing them back. I thought I had a health problem. I have been eating Italian pine nuts for years with no trouble. I never would have guessed this was the source of the horrible taste. Perhaps Trader Joe should stop selling the pine nuts from China and frankly too many of the products they sell have serious problems. I think we really need to insist on country of origin labeling

    Hey everyone, I tried drinking tomatoe juice this morning. I was worried at first, thinking it would taste horrible because of the bitter mouth syndrome we’ve all been talking about. I am passing this on to you…it was not bitter and did not taste bad at all. In fact, it enabled me to get through the day with little to no bitter taste in my mouth. Toward evening it came back, but I intend to continue drinking the tomatoe juice every day. I think the acid is what makes it work. I remembered the old remedy of tomatoe juice baths for dogs or cats who’ve been sprayed by a skunk. (I’m a country girl) The tomatoe juice helps to get rid of the stink so I figured it might work on this and it did. I took the pine nuts back to Trader Joes and told them why. The two people helping me had no idea what I was talking about when I told them. But, I did get my money back. Then I bought a chocolate bar…it tasted yummy, so I know the tomatoe juiced worked.

    Well, I guess I am the latest victim. I’m a culinary student about to work in a kitchen for the first time in two days. It seems cruel that this should happen now. I don’t understand why major retailer like Costco and Trader Joes are still selling these terrible chinese pine nuts, if they’ve known about the problems for years now!!!! Is there any way to get rid of the terrible taste in my mouth? Has anyone found something that helps to get rid of the taste?

    My whole family got pine nut mouth from some chinese pine nuts we ate over the weekend. Today is day three or four. I am so glad that I found this info on google, or I would have been seriously worried. This was horrible – no more pine nuts for me.

  823. Marilyn

    After posting the tomatoe juice cure, which helped but didn’t remove the bitter taste completely, I tried a salt water gargle. That did the trick…bitter taste gone. It’s a good thing too, because two days later I was drinking the solution prep for a scheduled colonoscopy. That’s bad enough I didn’t want to make it worse by the bitter taste in my mouth.

    Really, you have to try the salt water gargle…make it strong!

    This is so strange! I was researching why I had a bitter taste in my mouth and this is the first article I found.

    I recently made a large batch of pesto using pine nuts purchased from Trader Joe’s! And the taste in my mouth started shortly after eating the pesto for the first time.

    I’m thankful to have found this out, was getting worried!

    I’ve never had problems with pine nuts before but they have been getting expensive and I found some cheaper ones supplied by a snack food company in S Australia. I used them for the first time recently and then developed the bitter taste in the mouth about a day later. I had no idea what was wrong and threw out some lovely soup I had made from home grown vegetables before I realized that everything else tasted awful too. Then I tried google and found this site. What a relief!
    I rang the supplier and they had never heard of this problem but confirmed that the pine nuts came from China. They are quite easy to identify. The ‘normal’ pine nuts are about 13-14mm long and an even cream colour. These Chinese ones are shorter, about 8-9mm long, and darker in colour with an obvious marking at the end where they have been attached to the shell. They taste a little stronger than usual and the resin flavour is more obvious.
    I ate some normal pine nuts yesterday. No problems!

    Bought pine nuts from the prepackaged nut section in the A & P last week (and sure enough, upon investigation they are indeed *from China*). I have been eating pine nuts my whole life (I am from a Mediterranean background) and NEVER, EVER had such a problem as what I am experiencing…I ate two tablespoons on a Friday, and after eating dinner the next day on Saturday, I thought that the food I was eating was strangely bitter and that maybe something was wrong with one of the ingredients. However, the next day, the extremely bitter/metallic taste came back after eating breakfast, and thereafter, after eating whatever. I googled ‘bitter taste in mouth’ and everything on the page came up about pine nuts.
    One blog I read belonging to two ‘foodies’ gave a temporary remedy they discovered of lemon juice. They said to drink it in water all day long. I did something a bit different. I squeezed a tablespoon or two of fresh lemon juice and drank it straight *right before* eating anything. If you eat right after that, it makes the taste almost go away completely for a short enough period of time to finish a quick meal. It must temporarily neutralize whatever is going on with the metallic/bitter taste.

    I am on day 3 of this malady now, and I really hope it goes away. It is really horrible!

    I send an email to the FDA website about it. One blog I read said that the writer called the FDA, but they said that the FDA told them that they had not had enough complainst to justify the investigation. So PLEASE everyone, write to them, so that whatever this is can be uncovered!! It certainly does not seem to be a good or safe thing.

  829. Watch Out for Ongoing Bitter Taste from Pine Nuts

    […] But buy ‘em cheaply and it’s buyer beware. According to USA Today, Costco has had “a few complaints” about their pine nuts, but couldn’t get to the bottom of it in lab tests. (Here’s more about Costco pine nuts on Chowhound.) I bought mine toasted at Trader Joe’s, where the package said the nuts might have come from Korean, Russia or Vietnam. The pine nuts were tiny, by the way — nothing like the ones in the photo. When I took the opened bag back and complained to a store supervisor, he said the Food and Drug Administration says pine nuts are safe for consumption, while also stating that they “affect one in every 20 people.” That seems like a lot to me. (Coincidentally, guess who else was affected by Trader Joe’s pine nuts? Nicole of Pinch my Salt.) […]

    Thank you for your article. I have had a strange bitter taste in the back of my mouth for a few days. I googled ‘bitter taste in mouth’ and found out that pine nuts can cause Pine Mouth. A few days ago I just happened to eat a small handful of pine nuts. They were also from Trader Joe’s. I hope this taste goes away soon. It is really annoying!

    Oh this is the most disgusting thing ever. I love pesto and have always made it with walnuts. Never had a problem…until I decided to make it with PINE NUTS! Oh it is terrible. I bought mine in bulk from a grocery store that sells better quality stuff. Weird though that my husband is not experiencing this and he ate it too. So unfair! The only thing that helps is V8 and hot water with lemon. I am going to try hot water with ginger. And when I say “helps” I mean helps not cures! 😉

    *It took five and a half days for the taste to go away. Having a tablespoon of freshly squeezed lemon juice right before I ate neutralized the taste somewhat and I was able to eat.
    *I called my state’s FDA and reported it.
    *I called the company (local, but sourced from China) that sold it, and reported it.

    You are lucky Alice, I`m on my sixth month and it is definitely due to pine nuts, as I have undergone all tests extensively. It was subsiding after having steroids for 2 months, but 2 days ago my wife made a summer dish where she added two tablespoons of pesto, and assured me the nuts were the edible ones. The next day the severe bitterness resurfaced, so probably it is some form of allergy precipitated by the previous inedible pine nuts. Previously I never had any problems with pine nuts.

    This happened to me in November 1009 and I quickly discovered this website. Last month my grown son on the opposite coast described having symptoms like this a few months ago. He had not made the pine-nut connection, but after I mentioned this condition, he realized that this was probably what happened to him.

    I have the same problem. I eat pesto and pine nuts all the time, but a few days ago I added Trader Joe’s-purchased pine nuts to some grocery store-bought pesto (I think it was an Italian label) and voila, I have this horrible malady. I’ve been storing the pine nuts in the fridge and have never had an issue before, so it make me wonder if it’s from the pesto, which was made with pine nuts not walnuts. Ugh. Thanks for the info. At least I don’t have to worry I’m dying! 😉

    Lee, if you read these posts you will find out that Trader Joe’s brand is very common for giving people pine nut mouth. It was the culprit for me and my husband. Trader Joe’s near LAX gave us our $$ back and acknowledged that they have had many complaints. The longer lighter pine nut appears to be the one we should be eating. The smaller darker ones (TJ’s brand) are the culprits. Hope is goes away soon – mine took 3 weeks to clear up.

    Finding this was amazing because I would have called the doctor – I “splurged” and bought some pine nuts 4 days ago. Two handfuls later and I can’t eat anything without wearing a putrid face. My intent was to make pesto but instead I think I made a diet product. I hope it goes away soon!

    Although my symptoms were starting to depart (after 5 days and homemade ginger tea) I learned about Arak or Araq- – I believe that Anise is the key. Ouzo may help also. I put an ounce in my mouth and held it for as long as I could. (it was during work so I spit it out) My eyes watered and my mouth was stinging but an hour later I had a sandwich and it tasted great!!!
    (I was told to do it every six hours until it completely goes away)

    Thank goodness for this post, I went on a camping trip and had some pine nuts for the first time the pine nuts didn’t have a bad taste, but the next day every thing I ate tasted bitter I would have never guessed it was caused from the pine nuts, if I had not found this blog I would have worried and wasted money going to the Doctor, the bitterness lasted about a week regardless of mouthwash, tongue scrapping, teeth brushing, I purchased the pine nuts from a Walmart in Florida and the origin was China, I don’t think I will ever eat pine nuts again regardless of the origin.

    The exact same thing has happened to me! I ate Pine Nuts from Trader Joe’s. I think Trader Joe’s is great – so, no bad marks for them.

    Wow, thanks for the post and all the comments. I too used the Trader Joe’s pine nuts in a recipe and two days later began to have the most foul taste in my mouth when I eat. Two other people ate the same dish with the same pine nuts and they are fine. I was beginning to worry and then remembered reading quite some time ago about pine nuts causing pine mouth. Because my symptoms didn’t arise until two days after eating them I didn’t make the connection right away. I am hoping it doesn’t last much longer.

    Trader Joe’s update. I called the corporate office and spoke with someone who has been handling the “pine mouth” problem and she said they now have a warning on the label. They initially thought the problem was isolated to raw pine nuts so they limited their selection to dry toasted. However, they are still receiving complaints from customers. She said in relation to the volume they sell the number of reported problems is miniscule. However, if people don’t report they don’t know. She asked me to return the bag to my local store and let them know to send it to corporate. They log in the tracking number but she said thus far there hasn’t been any correlation between distributors or country of origin. And some people who eat from the same lot are unaffected, which was what happened to us. She also said that organic pine nuts have had the same report of “pine mouth” so it proving difficult to pin point exactly what is causing this in some people. If you experience “pine mouth” please notify the vendor and return the bag. It is day four and I still have that horrid taste after I eat. Hoping it doesn’t go on much longer. It is better than it was, but not gone yet.

    Hi all. Further to my above comments, and to those who are suffering with this for more than a few days, please try my suggestion of squeezing a tablespoon of freshly squeezed lemon juice and consuming it (especially swishing it around your mouth where you sense the bitterness coming from), and come back and let me know if it helped neutralize the bitterness as it did with me and others who gave me the suggestion. I think it also helped get rid of it more quickly (I had it for approx. four days).
    I just got back from Greece and ate some yummy hummus with pine nuts at a Lebanese restaurant and had no problem. I went to a store that was selling nuts out of barrels and I think the purveyor lied to me because his nuts were the small shape of Chinese nuts, so we didn’t eat them.
    I went to the supermarket there (in Athens) and found these little bags of pine nuts that were not only cheap but also wrote that the country of origin was TURKEY, and they were not small like the Chinese ones, so I bought a few of them and brought them back. We have had some already and sure enough, there was no problem. I only wish that I had bought more of them.
    The bottom line is that, pignoli/pine nuts were always expensive because they were from the Mediterranean area. Costco and Trader Joe’s (as well as that dishonest purveyor in Greece apparently) saw that they could get large quantities cheap from China, and assumed that it was the same thing, but it seems that they are not. So, go for small amounts from Spain, Italy, Greece and Turkey, and savour them as the delicacy they are meant to be!!

    P.S….PLEASE, call your state’s FDA.

    It doesn’t take more than five minutes to look up their number on the internet and lodge your complaint with an operator.

    If we don’t, trust me, Costco and other companies that are getting them really cheaply from China and other Far Eastern countries will NOT stop selling them!!!! I have been told that unless they get enough calls, they will not be able to do anything. Obviously, calling the companies is not enough for them to stop carrying this popular and profitable item in bulk from China.

    I got mine pine nuts from Trader Joe’s. They are expensive, nasty, and this is simply disgusting that such reputable store sells them for years. The 1st posting on this blog has been made in 2009, now it’s 2011 now. I’m going to talk to the store manager, but not sure if it will help. I ate the nuts 5 days ago and still have the bitter taste in my mouth. It made me search the net as well. Shame on Trader Joe’s!

    I contacted them several months ago and they claimed they would not buy again from China once this “batch” was used up. Interestingly, it still seems to be an issue. Must have been one heck of a big batch. Bottom line, they don’t seem to care. They sell a lot of Chinese food at Trader Joe’s but so does Whole Foods and other higher end stores. I’ve taken to really looking at the country of origin when I’m shopping. Not just at Trader Joe’s but even in my little neighborhood grocer. Just so you know, the small jars of pine nuts that are packaged in the US are generally from China too. I have only one source for pine nuts now and it’s on Arthur Avenue in the Bronx at a store called Teitel Brothers. They import them from Spain or Italy only. They are approximately a million dollars per pound but I’ll pay it just to never have pine mouth again.

    Well, I wrote to Trader Joe’s where I purchased it and also sent email to FDA. This is simply unacceptable. I FEEL ILL. It’s not a matter of inconvenience ONLY, it’s lower energy, productivity, nausea… if I wouldn’t do the research on the net first, I’d skip a few hours from work, would go see a doctor and pay my fair share for the visit. The insurance would pay the rest. This is too big price for us to pay to some nasty freak who probably reading these postings and laughing at us and getting richer and richer. I’ll wait to hear from FDA.

    I would highly recommend the readers of this blog do some more research on this subject (maybe even the news-source type!). Even the Wikipedia page that is cited in the article implies that this seems to be an allergy situation. Although this obviously isn’t a full-blown pine nut allergy, allergies of this type are quite common. It is far more likely that our bodies (yes, mine too, but I am not about to blame “bad food”) react poorly to pine nuts (certain variations more than others) and that we should just be aware of this when eating.

    4:17 pm  Oct 29th, 2011
  854. Marilyn

    Regardless that you seem to be somewhat sarcastic in your comment, I would have to agree that this problem could be related to an allergy, considering the fact that my husband eat the same pine nuts as myself and did not have the same reaction.
    I guess that would let Trader Joes, which is where I made my purchase, off the hook. However, their pine nuts did not only leave the bitter taste in my mouth, they did not taste like pine nuts, rather it was similar to eating a stale sunflower seed. I had a check in my mind about it, regardless I did not have time to return them and look for another source, I used them anyway. Lesson learned.

    6:58 am  Oct 30th, 2011
  855. Alice K.

    I absolutely *disagree* that this is an allergy because I have been eating my recently purchased Turkish pine nuts and have had absolutely NO problem…only ever had it with a certain bag of Chinese origin pine nuts, as I have documented above.
    *INTERESTINGLY*, just recently, I saw tiny, expensive bags of pine nuts prominently displayed in my local A & P, and also at a D’Agostino…with origins from Turkey and Italy. I firmly believe that this is in response to the many complaints about Chinese pine nuts. Let’s keep it up and get the word out! (by the way, it is much easier to *call* your local FDA and issue your complaint to a human being–just do a simple google search to get their number).
    I have recently been thinking that since we have pine trees in the U.S., how come there are no pine nuts from the U.S.? Perhaps because the local pine trees are a different species (inedible) than the Mediterranean ones! THAT is probably what the case is with China. There trees are probably an inedible species…and if they were edible, then why do pine nuts not a traditional part of Asian cuisine as it is in the Mediterranean countries where the truly edible ones come from?!? Think about it!

    Tim, I have no problem with organic pine nuts from Italy. I think it’s the poor quality of this smaller more bitter type rather than an allergy.

    I actually wonder if it’s a different nut altogether. It looks different than the Spanish or Italian ones.

    Thanks for the info – I was also searching google for bitter taste as I’ve had one for over a week now. When I saw pine nuts pop up I was intrigued as I had recently opened my second bag in the last month.
    They were, of course, from Trader Joes. I’m guessing they use an inferior quality which is perhaps more likely to cause this phenomenon. Two years after your original post and they now have a warning on the bag stating “some individuals may experience a reaction to eating pine nuts characterized by a lingering bitter or metallic taste”

    Guess I’ll have to spend the extra $$ and save myself from weeks of aspirin-mouth.

    EXACTLY! If these were edible pine nuts, would Thailand, Russia, China, (Trader Joe’s origins) have used them traditionally in their cuisine?

    I’ve posted before but it seems people didn’t take it seriously. Gargle (and swallow a little) Ouzo. I’m not sure if it was the anise or what but It worked for me!

    I am a retired ear,nose and throat doctor and noticed a bitter taste in my mouth for the past week. I examined my mouth and throat but found nothing. I was considering going to the doctor who replaced me for a more thorough exam but I had dinner with a friend of mine who had similar symptoms. He told me about this website. I had eaten pine nuts from Trader Joe’s before the symptoms occured. They were from Korea, Russia and Vietnam. I will take them back to TJ’s. In response to other comments, all pine nuts are edible. The pine nuts found in stores are from Italian stone pines. They will grow anywhere but harvesting from the hard shells is labor intensive so that is probably why they come from 3rd world countries

    I have this “Pine Mouth” right now and I’m so freaked out by it! Just in time to ruin my Thanksgiving dinner too. I still have my bag — they are NOT from Trader Joe’s but from a local chain called ShopRite owned by Wakefern Foods — but they are supplied by an unknown vendor. This is horrible. I still have half my bag and if I look I can see a couple little small round pine nuts mixed in with the long narrow ones.

    The Trader Joe’s letter is disgusting. This used to be a reliable retailer before they were bought by investors.

    I’m convinced these are poison — articles published in the UK mention that even the Chinese regulatory bodies admit this strain is ‘not for human consumption’. Who knows what kind of toxic inflammation I’ve picked up?

    So angry! And I threw out a wonderful pot roast I thought was spoiled due to bitterness & metallic taste. Boooo!!!

    so glad to find this. my symptoms match many others above. I all of the sudden got this awful taste like a chemical in mouth and it has lasted for several days. As soon as I read this… ah ha moment as the day before this bitter aftertaste, you guessed it , I had eaten a couple of handfuls of pine nuts. so after reading this, I looked at my package of pine nuts and you guessed it again they were from china, now they are in the trash and hopefully one of the remedies listed above will help remove this terrible bitter after taste. Who would have guessed something like that would last for several days. weird. but great to figure out the cause. thank you for posting this story and for all the comments posted also.

    well, Any guess as to why I am here and commenting! Bitter taste..small handful of pine nuts everyday..Trader Joe’s. I am taking mine back since they have a satisfaction guaranteed policy.
    For the last week I have been brushing as far back as I could on my tongue. I thought ‘man these bacterias, sure are poopin a lot farther back these days.’ I have gone through a pack of gum a day. We all bought our pine nuts at T.J.’s b/c they are $9.99 a bag. Now I really hope that Whole foods Pine nuts for $29.99/lb do not cause this effect?!

    I can’t believe this! I’ve been eatingpine nuts for years, no problem. Bought a bag from…yes…Trader Joe’s, and made delicious Italian pignoli cookies a few days ago. The weird thing is 5 or 6 other people tasted the cookies and had no problem, but I have this back-of-the-tongue bitterness described here ever since I ate the pine nuts. I wonder if this is because I ate a handful of raw pine nuts while baking, while the others ate the cookies and the nuts on the cookies were somewhat toasted from baking them? I had no idea this was a syndrome; like others, I googled “bitterness in mouth” and found all these reports! Sincerely hopes this gets better in time for the Christmas dinner I’m cooking!

    I bought a large bag from Sams club earlier this year and kept them in the freezer. I opened them a couple days ago and used some toasted in salads twice in the last 3 days. I also ate a few before they were toasted. No problems were noted when we ate them. Last night, I started having this nasty bitter taste when I’m eating and it was worse at lunch. My husband said he hasn’t noticed anything. I guess this will keep me from eating much over the balance of the holiday. Hope it doesn’t last long.

    The taste lasted about 3 to 4 days for me. Because the pignoli cookies were such a hit, I ordered Italian pine nuts from at $18 for a HALF pound. I plan on keeping them in the freezer and seeing how it goes. This must be an individual reaction, because no one else who ate the cookies had a problem, including my 83-year-old mother!

    I read an article about “Pine Mouth”, the bitter taste people can get in their mouths after eating pine nuts. This article said the problem was that some companies are selling the inedible variety of pine nuts. Pine nuts are in high demand and expensive, so some companies are passing off inedible pine nuts as edible ones since you can’t tell by looking at the pine nuts (at least consumers can’t tell the difference). It is really consumer fraud, not a case of rancid pine nuts.

    First, I LOVE Trader Joe’s. I’ve shopped there for years and continue to shop at a great grocery store! With that said, I bought pine nuts at Trader Joe’s a couple months ago.. I ate most of the bag in salads with no ill effects. However, twice I popped a handful into my mouth before bedtime. The 2nd time was lead to two WEEKS of my taste buds telling me everything was bitter and metallic. A horrible experience. the only way i figured it out was finding other people’s comments on the internet. Googled “metallic and bitter taste” and up popped a very long story about a person eating pine nuts and 2 days later the bitterness occured. Same for me. I tossed the nuts in the trash. Later I found a 2nd bag in the drawer and before tossing those it the trash I saw on the bag printed clearly, “may cause bitterness” or something like that. Here is my complaint with Trader Joe’s. If they did more research, they would probably find that pine nuts are not the problem. Most likely it is the source: that is, chemicals used (China) or substituting inedible pine nuts for edible. If i recall on the package it said the nuts come from Russia, Vietnam and someother place. Trader Joe’s should get their pine nuts from a reputable source!!!!

    By the way, it took several weeks before all the bitterness went away!!!

  878. Pinenuts did it again!

    2 days ago took frozen Trader Joes pinenuts out of freezer and enjoyed them. (When I checked the date it was 2010- probably too long to keep them even for the freezer). Today, I experienced the yucky bitter taste in back of mouth – googled it and found this site. Now I am thankful that this will pass in a few days and I can enjoy my food thoroughly again!

    I am sure glad I found this information. I have been having a horrible taste on my tongue for the last few days. It worsens when I drink or eat something. I could not figure out what was causing it. Now that I have read what you stated, I have been eating pine nuts for the last several days in a salad. They are Frieda’s Brand and state Made in China. I bought these at a Kroger store in Michigan. I feel so much better knowing what is causing this horrid taste in my mouth. I hope it goes away soon. Thank you so much.

    I thought it might be a bitter pesticide on the Medjool dates I was eating, but when I goggled the words bitter, aftertaste, and Medjool I came up with “pine mouth”…. I also thought the bitterness might be coming from bananas, juiced tangerines, etc….

    Now I realize that the level of bitterness I have tasted when eating things (that are not spicy) has been going up and down over the last week or so as I have gone through about a half a bag (8oz/bag) of Trader Joes Raw Pignolias from Korea, Russia, and Vietnam. Spicy foods offer some relief. My guess is that this batch of pine nuts are repackaged from China.

    I remember tasting one bad pine nut but not bothering to spit it out. I wonder if it was rotten with a molecule similar to aflatoxin (tasteless).

    Perhaps the “pine mouth” molecules are not bitter until they are broken down in the liver. I don’t feel inflammation, so maybe the molecules are not carcinogenic. Maybe the bitterness is suggesting that the molecule prevents the metabolism of sugar or depletes the body of a needed nutrient. I’m just guessing here. In any event, this “pine mouth” condition does not seem healthy.

    I tried eating a bunch of celery to cleanse my palate but the dates still have a bitter aftertaste. Maybe if I go to they gym and work out then whatever this condition is might go through my system faster.

    I doubt I will ever risk eating pine nuts again.

    Yes, my spouse and I had the exact same symptoms after eating Chinese pine nuts from Winco. They sure are cheaper than the ones grown in the US, but we ended up thinking we’d been poisoned. Everything tasted bitter and horrible.
    The real worry was that my spouse, who has kidney problems, noticed severe kidney pain right after eating the nuts, as well.

    Of course the contaminated nuts are from China. No surprise there.

    Trader Joe’s – reported to TJ’s & FDA. Over 5 weeks of symptoms. This is not a “easy way to diet”, it is life altering. This is not like asparagus, or any other reaction that is consistent over time. I have eaten pine/pinon nuts my entire life and never had an issue until now. I have also eaten TJ’s Mediterranean hummus many many times before (for years) and never had this issue. I have tried every remedy I have seen online in forms (listerine, gargling with peroxide, scraping & brushing my tongue, gum, oil pulls, tomato juice, lemons, charcoal, exposure to sweet and sour extremes, etc.). I have not tried anise or wonder fruit, but will today. I have done tons of online research about this and found some good resources, but no cure.

    This just happened to me and my family. We were vacationing in new Mexico and stopped at a local Pizza place that served Pine nuts (Pinon) on the pizza.. So we indulged! This was Sunday, the Tuesday we all began experiencing the same naty taste in our mouth. Each thought nothing of it and it was not discovered until I mentioned to my husband the nasty taste and to his surprise, he said “me too!’ Then we got home and asked the kids (teens) if they have experienced a bad taste in their mouth and attempted to throw them off by asking “is it on the tip of your tongue” and they said “no, its at the back of my mouth” We called our doctor, who said it could be anything from a gas leak in our home, exposure to a natural gas leak in New Mexico (which was discovered), or exposure to something at a natural hot Springs that we indulged in while vacationing. But Pine Mouth seams to be a closer fit!!!!!!
