Oral Allergy Syndrome

My allergist said that all of the allergy medicine out there doesn't really help with OAS. You can take benadryl, but then you're trading the sleepiness for the fruit/veggies! She said the best thing you can do is just avoid the triggers.

Also, did you know that cooking breaks down the protein that causes the reaction? So canned and dried fruit/veggies work (freeze dried does not, trust me), you can blanch or nuke fruit and veggies for a little bit too. It's just finding the right amount of cooking that works.

I feel your pain. All I want to do in the summer is bite in to a nice, soft, juicy peach, but the hives and asthma attack are not worth it. Every now and then I think "This is ridiculous. It's all in my head. Whoever heard of a fresh-fruit only allergy? Suck it up and eat one." Uh yeah, no, that approach isn't so successful.

It's worth asking. However, my sister, who also has it, has gotten shots and they didn't really help her. You should definitely go through the allergy testing. It's good to at least know what you need to watch out for. I've had the scratch test, but it was negative for actual food allergies, thank goodness!

that sucks - I have this too, but it seems not as bad as you Mine is worst with cherries (throat itches!), peaches and apples. I just eat them anyway and then drink a lot of water and maybe "chase it" with something else that doesn't cause symptoms. It seems to help a little if I quickly wash out my mouth w/ the water or other food. Maybe that could help you? Otherwise I just deal with it and make sure to wash my hands too (once after eating a peach I rubbed my eye and it got all swollen, red and itchy for a few hours - oops).
I did read somewhere that peeling the fruit can help too - for example before you eat an apple peel the skin as that is where most of the protein you're reacting to is (though that wouldn't explain your reaction to kiwi, so maybe this isn't true...)

Good luck!

I have it horrbily. My lips swell up and my throat starts scrathing and itching. Its crazy!

I just avoid those foods, and most of the time I am good with it. I have it bad with bananas though and I will still eat a banana from time to time. I had a mild reaction to the almond milk, but I kept drinking it and it has gotten better, I have no reaction to it now. My list of foods I cant eat are:
raw carrots
watermelon
bananas
kiwis
avacados
cucumbers
raw tomatos
theres probably more too. Sometimes when I cut up lettuce my hands get all blotchy and stuff, allergies just suck.

I was put on an allergy medicine that blocks all histamine production, but I had to take it religiously for months before it would work. I was actually able to get rid of my OAS when I started eating Paleo/primal, but it took 2 to 3 months before I could. I had gone 15 years without eating a banana and I can still remember how excited I was the day I was able to eat one and not have to spend the rest of the day in bed, sleeping off a huge dose of benadryl. Mine was to the point where if it was raw and a fruit or veggie I couldn't eat it. If I eat any wheat, corn, or anything containing gluten my OAS will act up again, but I'm able to eat so many healthy things that I wasn't able to before. I still have a hard time with melons, but I'll take that over not being able to eat ANYTHING.

I just wanted to check in and say hi- since I have very few fruits and veggies I can eat raw and not getting enough of them in (I mean, how many apples and strawberries can one person eat, because thats it and I worry apples of certain varieties are the causes of some recent reactions)! I should say I CAN eat blueberries, raspberries and blackberries but they aren't always in season or looking edible when they are ha! So we got a ninja master prep today and I'm gonna blend those with some trop50 and frozen yogurt to get my fruits in more.... I did allergy testing then shots and they said they couldn't guarantee the OAS would get better...and it didn't and they said histamine blockers still aren't truly safe- especially in those with asthma- even if you take the meds regularly and eat the foods you could still suffer anaphylaxis if you're at the stage where you have OAS year round and not just during high pollen seasons...so make sure you follow closely with your doctor!

Current OAS enemies: RAW- Bananas, Tomatoes, Pineapple, Watermelon, Canteloupe,Cucumber, Avocado, Kiwi, Red/Yellow/Orange and especially green peppers (thought that one was gonna send mme to the hospital even after being cooked into a pasta sauce)!

I think sometimes I miss bananas the most- why do so many smoothies call for them? LOL Hope everyone is doing well!

ETA: Washing raw potatoes gives me itchy hands and spots and has for years and never realized it was a link to this along with having the problem with bananas causing instant "heartburn" and the edges of my mouth to burn for 10 years before I had issues with other fruits and veggies!

I've had OAS for years and unfortunately nothing works for me. I've been wondering how to keep myself healthy with so many food limitations. If it is raw it is pretty much right out for me, including lettuce, spinach, most fruit... Mine has gotten so bad that if something is even closely related, I have a reaction. For example, unprocessed soy, cumin, and any gum (Xanthan, guar, etc). I guess XG can be grown on soy agar, and the others are vaguely related to some legume I react to. Anyway, peeling worked for me for a while, because there is more protein in the peel, but that doesn't do it for me anymore. Cooking the food denatures the protein, so I just have to make sure I cook everything well. It's a drag. I hope yours stays relatively mild!! Be aware that IBS symptoms can also be a manifestation of OAS apparently.

My sister had severe OAS for many years and avoided all uncooked fruits and vegetables due to a severe anaphylactic reaction. She tried various allergy specialists, naturopaths etc with no improvement

A family friend recommended a traditional chinese medicine doctor, who prescribed herbal medicine and acupuncture. Despite her skepticism, it actually worked within a couple of months and she is still able to eat normally now, more than 10 years later (she still avoids watermelon though!). It was truly amazing - I wouldn't believe it if I hadn't seen it.

Hopefully this info can help someone out there

Slow reintroducing worked wonders for me and so glad I tried it otherwise I'd have missed out on many lovely foods... nuts, strawbs, apples etc.

I'm surprised so many people have this. Most people look at me like I'm crazy when I tell them my daughter and I are allergic to apples (and peaches, and pears, and apricots). I've never heard of OAS being life-threatening - just varying degrees of uncomfortable, so I'm surprised to hear people mention EPI pens, etc. I think that may be a different kind of food allergy, but I'm not an expert so I can't say for sure.
Anyway, if I'm really dying for some of the fruits that trigger my allergies, the following helps a lot:
1 - Wash the fruit well.
2 - CUT IT UP before eating and place small pieces in your mouth. If something gets on my lips (for instance if I bite into a whole apple) it's game over.
3 - Regular, seasonal allergy medication eases symptoms. I take Allegra since it is the only thing that works for my seasonal allergies.
4 - Drink lots of fluids inbetween bites.

Also, I had read that when women are pregnant their allergies can go away. This happened with my first child. When I was pregnant, and for about 3 years after, my allergies magically cleared up. But then they came back with a vengeance and didn't ease up with the birth of my second child. Just a thought in case you had recently had a kid - you may not be as allergic as you used to be.
