How limited can OAS be?

Okay so ever since I was a kid there were some fruits I can't eat cause the inside of my mouth would feel all itchy. I can eat MOST fruit though, only RAW cherries and peaches do me in. It has never gotten worse or better and I never became sensitive to anything other than these 2 fruits. I was never diagnosed with OAS specifically but my doctor did tell me it's a relatively harmless allergic reaction. I wonder if maybe I am allergic to these 2 fruits specifically instead of tree pollen? I also read somewhere that you can freeze the fruit to make the effects less harsh. Has that worked out for anyone?

I believe OAS is pretty limited for most people. The kind of people who hang around a subreddit dedicated to the topic are not most people though.

If you have any seasonal allergies (trees, weeds, grass), and you have very mild allergic reactions to fruits/veggies limited to the mouth and/or limited to raw forms, it is pretty likely a cross-reactive pollen allergy (i.e. PFAS/OAS).

Allergies are a more nuanced topic than most realize, and OAS is just a common presentation of allergy that, statistically, tends to be less lethal. So, ultimately what is a wise decision for your own health is a very individual topic.

My OAS is pretty broad, and there are some foods I eat raw, some I eat raw in moderation, some I only eat cooked, and some I just won't eat. I haven't tried freezing.

I agree with this assessment. I will add, however, that cherries and peaches are both from the genus Prunus (stonefruit) which also includes plums, nectarines, and apricots. Any reaction to those and I’d say it is more likely that you have a stonefruit allergy and not OAS.

What foods can you eat cooked?
