Quote:

Allergic reactions to fruit and vegetables are usually mild and often just affect the mouth, causing itching, a rash, or blisters where the food touches the lips and mouth. This is called oral allergy syndrome. (A number of people who react in this way to fruit or vegetables will also react to pollen from some trees and weeds. So, for example, people who are allergic to birch pollen are also likely to be allergic to apples.[2])
[edit] Mitigation

For those allergic to fruits, cooking may help reduce or eliminate the reaction to some fruits.[2]

People with this allergy might not necessarily be allergic to citrus fruits.[citation needed]

I think it may be because of all the proteolytic enzymes it has. I know what you mean but it doesn't bother me particularly. It does bother me if pineapple is part of my meal and I eat it first. Whatever I eat next tastes like vermiculite
