If you experience an allergic reaction to certain vegetables, fruits, or nuts you just might have what’s called “Oral Allergy Syndrome.” OAS is a food or fruit-pollen syndrome that affects about 25% of people with “common” allergies. A protein in the those foods closely resemble tree and weed pollen.
Your immune system gets fooled and sees these proteins as an allergen and triggers the release of histamine — meaning itchy, scratchy, burning sensation. For most people with OAS, the effects are often felt in your mouth, but can also be felt in the back of the throat, eyes, ears, nose and skin too.
