This is something I have dealt with most my life. And I'm not talking like an annoying ache. I mean full on, screaming, ripping-your-guts kind of pain.

I don't eat them so no need to tell me that part, heheh.

But I've always wondered why these particular foods cause such distress? Is it a particular protein that connects them all? Most health professionals I have asked in the past have given me the "I-dunno" shrug time and time again. One doctor did suggest some issue in relation to latex, but I'm not allergic to latex.

Anyway, I trust the knowledge and scientific fervor of this community, so I figured why not ask here? Does anyone else have this problem?

Banana is usually fine, don't know about Kiwis, but whole avocado is giving me serious stomach grief. I'm going to try just eating a half and seeing how I feel. – thisiswilson Jan 29 at 20:09

I also found myself getting very ill from Avocados and I know that you can be allergic to them. I did a little research and found a perfect answer for you!

http://foodallergens.ifr.ac.uk/food.lasso?selected_food=4

Avocado allergy can take two different forms: one associated with allergy to tree pollen, such as birch, and another type associated with latex allergy. People with birch-pollen allergy can develop symptoms either immediately or up to 1 hour after eating fresh avocado or an avocado-containing food. Symptoms comprise local reactions in the mouth and throat with itching and inflammation (called oral allergy syndrome, OAS).

Others develop an avocado allergy because of the similarity between the allergens in avocado and natural rubber latex (e.g. gloves, condoms, balloons) a condition known as the latex-fruit syndrome. Symptoms developed by these individuals comprise generalised urticaria, abdominal pain, vomiting and sometimes life-threatening symptoms. These individuals may also develop adverse reactions to chestnut, banana, mango and kiwi.

I can eat mangos, kiwi, and banana just fine, though I have never eaten a ton of those fruits. If I have guac on my chipotle I feel like I'm going to implode.

Jake, you are a rock star! Thank you for finding that link. Makes a ton of sense, particularly with the symptoms. I can eat mangos, but have never really eaten a lot, so I could possibly be susceptible to them as well. – LastingOne Jul 14 2011 at 19:16
Nice answer +1! FTW – Todd Jul 14 2011 at 21:40
Thanks LastingOne. I'm glad to help out! It's too bad that neither of us can really enjoy a good guac – JakeA Jul 18 2011 at 11:52
Omg, I know this is old but this explains so much. Thank you!! – Aughra Sep 20 2011 at 22:17

About 3 or 4 years ago I found myself getting severe abdominal pains on a daily basis. It got so bad one day that I actually found myself passing out and my right arm and hand had unbelievable pins and needles. I thought I was having a stroke. I went to my doctor and she ran all kinds of tests, including an abdominal ultrasound, but couldn't find anything wrong. At the time, although I didn't put it together, I was eating avocado every day. After much internet research I found several people who seemed to have the same symptoms I was getting, and the common denominator was avocado. I stopped eating it immediately and within a few days the pains went away.

Fast forward to this year, I had decided I was going to have a cobb salad, which includes avocado, at a restaurant. There were no adverse affects so I thought the problem was solved. Unfortunately a couple of weeks later, I had another dish which had avocado, and within an hour or so those same pains were back again. They weren't as bad as before, but enough for me to realize that I had to stay away from avocado altogether.

Dawn, I'm having the same reaction from a single bite of broccoli at lunch – after not having it for YEARS, because I know it does this to me! But it smelled so good, I thought I'd try again. Argh.

Try some very strong mint herbal tea, or a few drops of bitters, if you have them. Sip it, don't chug it. It's not an instant fix but it usually helps me!

Good luck & feel better!

I'm online seeking information because the last 3 times I've eaten avacado I suffered tremendously from stomach pain. The first time there was some avacado in sushi, the second time I ate 3/4 of an avacado (something I'd done a few times before without problems) and just the other night I ate about 1/4 cup of a spread that included cubed avacado. Each time my stomach pain has been worse with this week's being almost unbearable for 4 to 5 hours. In reflecting I also think that the last time I had a migraine (2 years ago) was probably the last time i ate avacado before the three times I' ve mentioned here. i also struggle with bananas and almonds. Sometimes I can eat these without a problem but usually I get pain somewhere in the range of terrible gassy-bloating to outright having to cancel plans because it hurts so much ( that day I had eaten a banana and almonds as a snack when I was super duper hungry.) after the reading I've done here I'm onvinced that my recent problems were caused by the avacado and I will no longer eat it. Thanks to others for doing the painful experimenting because that's what I was going to do but your posts have convinced me I don't have to I'll just avoid avacado.

I too experience horrible gut pains shortly after eating avocados. As a kid I had no problem but now as an adult I have to be really careful I personally believe this to be a genetic predisposition because both my mom and brother have the same avocado allergy.

Several years ago I started having severe stomach pains and vomiting whenever I ate bananas. Recently I started having the same pains every time I ate an avocado. This really sucks because I love them both. I know they are in the same family as latex and as I am a nurse I am really hoping I don't develop an allergy to it as well.

Thanks for that link! I get the same reaction from both bananas and avocado. It took some experimenting to figure it out...painful experimenting...but at least now I know to avoid them both. I'm glad to hear it's not just me. People look at me funny when I say that I'm allergic to them. :S It's strange though, as a kid, I ate bananas very frequently and never had any reaction. It's only since I was about 25 that I noticed the symptoms. Avocados however, I never tried until around the same time. I'm still experimenting with garlic too. It might have given me the same reaction, but I wasn't keeping track carefully enough. Typically I just try to avoid large amounts of it to be on the safe side.

Might be FODMAPS or Fructose malabsorption.

Probably coming in very late here but maybe this will help someone. I started eating avocados as a very young child-they were my moms favorite so we all grew up on them. Never had a problem. Then at age 22,when pregnant with my second child,I starte getting horrible stomach pains any time we ate at our favorite Mexican restaurant. I thought it was the salsa,the beans or something-anything but the guacamole. But I finally tried eliminating that and no problem. So I would ask for "no guacamole" but sometimes they would forget and put it on anyway. No big deal,I can just scrape it off. But I soon found that that didnt work-just the tiniest speck of it would put me in agony for 3-4 hours.Every couple of years I would try again and pay the price so I gave up. Then,after 20 years,I gave it a try and wow! No problem. I have been eating it since with never a problem. Until tonight. Hubby made guacomole,I had some with chips and BAM. I was in bed for four hours in terrible pain. This is after 20 years of eating it without a single problem. I am pretty sure I will never try it again. But how weird is it that this seems to be something that changes with me every 20 years? By the way,have never had a problem with any other foods or latex,although bananas did one time bother me just a tiny bit. I have never been big on bananas though so maybe I just never ate them enough to develop the allergy to them. I was a Phlebotomist for a time and so wore latex gloves every day but never a problem. Such a baffling allergy.

I cannot eat bananas, kiwi, avocados without horrible pain! My lips tingle if I blow up balloons as well. Never made the connection. Also have this same reaction if I eat eggs that aren't cooked in something. Scrambled eggs will put me to bed in horrible pain the same as those fruits. Funny thing is I had no adverse reaction to eggs when I was pregnant. Odd allergies!! I'm also allergic to all trees and grass pollen. No fun!!

I have experienced the same thing. I don't remember having problems with bananas as a child..but horrible stomach pains if I eat one now...same as avocado and kiwis are a crap shoot but I don't eat a lot of them anyways... I was very interested to see other people having the same problems. I always thought it was so weird because bananas are purported to be so easy on the stomach and part of the BRAT diet.

I am experiencing this right now.....it sucks!!! It happened a few weeks ago when I had a Taca salad, wasn't sure if it was the cheese, lettuce or avocado. Well, today I ate a whole avocado as a snack and 20 min later I am in the same gut-wrenching pain and feel woozy. It sucks cause I know it lasts at least 4 hours! Anyone know of anything to calm my stomach and ease the pain? I have a meeting in a couple of hours!

I haven't been able to eat banana's for years because of the horrific stomach pains I used to get. Then I started getting the same reaction from eating avocado. It wasn't as intense as eating a banana, but still pretty bad and it lasts for hours. Now I am having the same issue with almonds. Does anyone have an almond issue as well?

Almonds, bananas, mangos, kiwis, and avocados for me. It could be that they all have ridiculous levels of potassium. In my case it's that I have naturally high potassium levels and if my diet contains more potassium than I can handle my body hates me and my stomach hurts so bad.

nhpm900 -- an overdose of potassium can cause a stroke. You might want to check that out.

Ever since I got pregnant with my first child, I have been unable to eat bananas, avocado and raw mushrooms. I don't know why but they give me severe abdominal pain. I can eat cooked mushrooms but not raw. Crazy!

I have this problem with avocados and bananas, I'm comforted to know I'm not alone! I've been to the doctor and he can't find anything wrong with me physically, so I think it must be an allergy/sensitivity. Try laying on a heating pad, it's the only thing that helps me, just don't burn your skin! My heating pad is my best friend when I get a bout of this!

The only thing that helps me with this (I have banana and avocado problem...no problems, yet, with almonds, and ain't ABOUT to try a kiwi, which i've not had before) is over-the-counter Prilosec which you can get the generic, omeprazole, anywhere. I get it at walmart. It says take one tablet (20 mg) which didn't help, but my sister-in-law had 40 mg tablets that were prescribed by her doc and I was in intense pain once so I took one and it helped IMMEDIATELY (well, 20-30 minutes, anyway). So now, I just take 40 mg of the over-the-counter if I have a problem. Hope this helps someone!

It is the craziest thing! Severe abdominal pain, feel flushed, woozy, light headed about 30 min after eating banana. Started in my 20's. Now i get the same symptoms with avacado and mushrooms. Seriously some of my favorite foods. Every once in a while I will try a bite of avacado.. and once in a while I get away with it.. but when I don't, UGH so sorry I tried! I wish it had a name and a remedy!

I get severe pain eating avocado. A raw foodist made me raw soup...it was spicy. I never thought to ask until after I ate it...is there avocado in it? I called her and she said yes. it usually takes an hour or two to get the severe vomiting which goes away after about 3 hours. Waited...waited...and no reaction!!!! The raw foodist says the spices counteract it. Since then, I've thought about testing the theory again...but as above...am concerned I was not sick only cause I did not have it for while...but if I have it regularly again, I'll start to get sick again. The pain is absolutely terrible for 3 hours non-stop...but I love avocado. No reaction to bananas, kiwis....but I do not eat them much.

once again thought hmm I might try a bit of avocado on my toast tonight and see if it still gives me severe stomach cramp. its been awhile... and sure enough about an hour afterwards that familiar pain started! and its just easing now nearly 4hours later. dammit I love you and hate you avocado! ...it only started effecting me about a year ago and im 34, so i thought that seemed abit weird as I have always loved them and had no problems in the past...it started to happen with my younger brother last year also which seemed odd, but at least I wasn't the only one as i felt like abit of a freak for awhile there...now having looked on this site its seems more common than I would've thought... kind of relieved to read other similar stories and sad at the same time as no more avo's for me...... will miss those slimey little green beauties..:(
