Why am I allergic to fruit all of a sudden?
Allergic reactions to fruit are commonly associated with oral allergy syndrome (OAS). It’s also known as pollen-food allergy. OAS occurs from cross-reactivity. The immune system recognizes the similarity between pollen (a common allergen) and the proteins in raw fruits, vegetables, and tree nuts.
How do you test for oral allergy syndrome?
A diagnosis of oral allergy syndrome is based primarily on clinical history, but it should be confirmed by skin prick testing. In patients with allergies to airborne particles, itching or tingling in the mouth after eating fresh fruit or vegetables is enough to suspect oral allergy syndrome.

Are severe allergies and autoimmune disease?
“In autoimmunity, there is a different type of T-cell involved than in allergies. In an autoimmune response, tissue destruction occurs. With allergies, the immune system overreacts to harmless allergens. Interestingly, this is the same type of response that expels viruses, parasites, and bacteria from the body.”
