Good ol’ Oral Allergy Syndrome (OAS). Discovered it with bananas as a child, apple as a teen, and the following as a young adult: peaches, pears, apricots, kiwifruit, cherries, cantaloupe, honeydew melon, to name a few. It was weird how each fruit would effectively just flip a switch randomly during my development.

That said, cooking the fruit denatures the proteins, so eg. apple pie is great!
