I have anaphylaxis and severe asthma, and I have several known anaphylactic triggers, (such as all treenuts, certain types of pollen, and raw
fruit - especially apples) - but my new allergist I recently met with explained to me the reason I am allergic to raw fruit such as apples, peaches, pairs plumbs is because of a condition called "Oral Allergy Syndrome" where my tongue recognizes the fruit as pollen in its raw state.
