Does your mouth ever get after eating fruits or some vegetables? For me, if I eat strawberries or even walnuts my tongue feels cut up and then I notice my lips feel stingy. Turns out there's a thing called oral allergy syndrome and it happens when you are allergic to some kind of pollen. There are fruit and vegetables that have proteins that make your body think it's "that" kind of pollen that you are allergic too.
Most of the allergy-causing protein is found in the peel or skin so you can peel the fruit or you can microwave the fruit and vegetable for 30 seconds which is enough time for the heat to break down the protein. You can cut the fruit and let it sit for a bit.
