Food Intolerance - Follow Up

After my recent painful encounter with bananas, I did some research, to see how common the condition was, and maybe learn a little about it. I googled and came across a forum discussing the same topic.

I was surprised how widespread the condition is and how many people seem to suffer with it. I reproduced excerpts of peoples experiences, below.

Has Anyone Experienced Sudden Banana Intolerance?

by MF (1204)
Is there such a thing as developing sudden intolerance to bananas? My wife loves bananas, but has been unable to eat them for a few months without severe gut cramping. The other latex fruits like kiwis and avocados don't have any negative effects. Also the symptoms of fructose malabsorption don't fit either. Is this some kind of intolerance that can build up over time after cutting out major problems like gluten?

I've had banana intolerance for a while. I ate a banana that wasn't fully ripe. Then I got some nasty stomach cramps and felt unwell to the point I thought I was gonna faint. It was the under ripe banana. A couple days later I had a piece of ripe banana and the cramping started again. I didn't eat bananas for the next 6 months or so (did some gut healing in between) and I was able to reintroduce bananas again in my diet.

Is she by chance allergic to latex? There are a group of foods related to latex and you can have an allergy across the board or just a few. I can't tolerate bananas, cooked tomatoes, wheat, potatoes, tropical fruits, and for a time avocados. I've also had issues with foods I've eaten a lot of over time. A lack of cycling can bring on intolerance. That's how I was able to go back to having avocados. None for 6+ months.

I have an intolerance to bananas, grapes/raisins, kiwi, pineapple, raw spinach... those are the ones i know of... i did the research and its an amine intolerance... ur body lacks the ability to break down the proteins in that particular food.

Almost 31 years ago when I was pregnant I developed an intolerance to eggs, bananas and avocados. Thinking I would be fine after delivery with hormone shifts or whatever, but no. To this day I can't eat bananas, although I tolerate them in baked goods. I'm now vegan so eggs aren't a problem. Avocados, small amounts smashed are kinda okay but cubed aren't. I am guessing something with the process of digesting is to taxing on the system. Seems everyone has some food issues, hubby can't do tomatoes or onions.

Every day I would walk to work and eat a banana. After an hour of arriving, I would get severe stomach pains that grew worse and worse each day. I finally figured out it was raw bananas that were causing these pains. When I ate "Fried Bananas" (which are actually plantains) and cooked bananas, I wouldn't get the same reaction. I also have to order smoothies without bananas (which is a real hassle). Every six months or so I can get away with half of a banana, but I don't try and push it. I have no other Latex related allergies. Though I do not enjoy avocados, I love kiwis and consume them regularly.

I am very latex sensitive and recently found out that due to my sensitivity is the reason that I cannot eat broccoli, bananas or avocados. I never would have imagined that eggs would also be on this list but I am currently experiencing the same symptoms that I have when eating the other wrongs. Guess I will now add eggs to my cannot eat list :(

I've eaten bananas most of my life and loved them. 10 years ago at age 58 while vacationing in Puerto Rico I found myself getting very nauseous every morning shortly after eating a banana. I quit eating them in Puerto Rico and felt fine after that. When we got back home to Minnesota I started eating bananas again, but still got quite sick. I cannot eat bananas at all now. About once a year I would try just a bite of a banana and the result was the same. I can eat banana bread with no ill effects. Must be the heat in the baking that kills off whatever makes me sick. We were in a Starbucks where my wife and I ordered a banana/chocolate smoothie. I took a few sips. 20 minutes later I was violently ill. I’m not sure how this all started after 58 years, but it seems to be here to stay. No more bananas for me in this lifetime.

I too developed gut pain from bananas as a teenager I'm now 33. Around 21 could no longer eat eggs and developed an allergy to latex. About a year later I could no longer eat avacados. I still cannot eat any of these foods. I tried a banana when I was pregnant 3 years ago did ok but tried another a week later and got the gut pain. I ordered some tacos for dinner this evening and they had guacamole on them so I am now in horrible pain writing this trying to figure out what I can do to relieve the pain.

I always ate bananas. always. with no trouble. ever. i ate them raw. in protein shakes, on cereal. etc. Then, all of a sudden, last week, I ate one before bed. I woke up in the morning with the most intense stomach ache, cramps, pain, whatever you want to call it. every 10 minutes for two hours, i would run to the toilet with the most intense pain, and i would sweat, get pale, feel nauseous and then I would think I was about to make an explosion...and only a little would come out. next day, had a banana again in the morning and same thing happened for an hour. but i still thought it was something else. i was fine over the weekend. and then boom, it happened this morning. I will never have a banana again. sorry for the TMI but this is so weird. I guess I should do see my dr. btw. for three days before i ate that banana at night.. i was on a very strict diet, had only a protein bar, a salad and a piece of chicken for dinner. maybe it had something to do with my 3 day crash diet. who knows.

I am NOT allergic to any other fruit that I know of. Sometimes pineapples make my mouth a little raw but I eat them with no problem. I don't hardly eat mango. I do not have a problem with Kiwi. I have anaphalytic shock with brazil nuts but with bananas, there is NO ITCHING, SWELLING OR SKIN REACTIONS. Just DIgestive. My Brother says that when you get older your body cannot digest things sometimes and you develop a reaction that only gets worse. My sister cannot tolerate tomatoes, coffee, or Dairy once she turned 40. My mother has a new allergy to Soy yet Soy products in everything. Her blood test came back positive for Soy though.

I am 29 and in the last couple years I developed an allergy to bananas, avocado, and eggs just like another commenter mentioned. It really sucks because all three were a major part of my diet. I wish someone knew what caused this. Is there any sort of explanation?

Jessica_35 0 · February 26, 2013 at 12:53 AM
I have a latex/banana allergy and it started out like that. For the longest time I would have gut reactions when I ate bananas and no other reactions, then I developed a stronger latex allergy (can not touch latex without getting hives), now I cannot eat bananas at all without my throat getting scratchy and closing up. I can also not eat honeydew melon or cantaloupe anymore without a reaction. So in my experience, food intolerance can get worse the more you aggravate them. to date, no reaction to avocado, kiwi or nuts but I can not eat most foods that grow in South America for some reason.

I suddenly developed intolerance to eggs and advocadoes after my pregnancy, I did try the organic thinking it may be something chickens were fed or pesticides, and that did not make a difference. Then usually about 3 days of very easily digestable bland diet, as I found out that if I try to eat a normal diet right after an attack, any food (not bland or very easily digestable) can set it off again.

Never thought so many people with the same problem. I had sweats, paleness, extreme cramping, gas, bloat, vomiting, chills. finally discovered it was bananas... only raw ones. dried, cooked etc, NO PROBLEM. This is definitely an intolerance and not an allergy (no breathing/ itching issues) but I wondered what gets lost when a banana is dried or cooked that I'm intolerant to, I would love to know to avoid other foods that might have them as well, although, so far, only bananas are problematic.

After eating bananas, occasionally, for the first 50 years of my life, I suddenly developed a severe intolerance- in about 1/2 an hour, it started with numbness in my extremities, advancing to my core, I became extremely weak and dizzy and could barely crawl to bed; 12 hours later, I was "fine"! My doctor blamed it on a flu-bug. About two weeks later, I just happened to eat another banana, without even thinking about it. The same reaction, only faster - about 20 minutes and it was 24 hours before I even began to "feel normal"- -doc had no explanation except "possible allergic reaction"!! To this day, I do not eat raw bananas; I can eat them in "cooked form" like banana bread, or muffins, fried banana with something else - -no reaction! So, all you banana lovers, just eat them "cooked", in or with something else.

I have been doubled over in pain for the past 24 hours since i had eaten ONE Banana yesterday at lunch. Stomach feels like it is being cut open from the inside and the pain comes and goes. i will not be eating Bananas again. . . :-( Any other remedies anyone can think of?

Gary_B 0 · July 11, 2012 at 5:48 PM
I've had the same problem. I have no allergies (I've been tested) but found after eating one to two bananas daily for a period of time, I started cramping/feeling nauseous to the point where I stopped eating bananas. I read if you consume too many bananas, its possible for your body to react to something in bananas, your immune system begins to recognize it as a foreign invader.

About a year ago I become very ill after eating bananas. I suffered severe chest pains that radiated up into my face and had trouble breathing. I thought I might be having a heart attack but quickly took an antacid and drank some milk which calmed my symptoms. For dinner tonight I had a veggie wrap that contained avocado and I experienced the exact same symptoms. I had bananas since I figured out it was causing these symptoms and no more avocado!

For me, not with bananas, but I did notice that I was "fine" on dairy until going Paleo for a few months. Added dairy back in and watch out below! I think that sometimes we believe we are fine with something until our gut heals. Then the truth comes out.
