Why Some Summer Fruits Make Your Tongue Itch, Even If You're Not Allergic

Turns out, you might be experiencing oral allergy syndrome, also known as pollen fruit syndrome.
It’s likely happened to you: You take a bite of an apple, a kiwi or some berries and suddenly feel itchy around the mouth, even though you’re pretty sure you’re not allergic to the fruit you’ve just eaten. Why does that happen?
Experts refer to the phenomenon as oral allergy syndrome (OAS), also known as pollen fruit syndrome (PFT). The indisposition is a pretty common one and it’s the result of cross-reactivity. Simply speaking: your body recognizes the proteins in the fresh fruit you just consumed as similar to those found in pollen, which you’re actually allergic to.
