Although an individual could be allergic to any food, such as fruits, vegetables, and meats, they are not as common as the following eight foods, which account for 90 percent of all food-allergic reactions:

- Milk

- Egg

- Peanut

- Tree nut (walnut, cashew, etc.)

- Fish

- Shellfish

- Soy

- Wheat

Contrary to common belief, food additives (E-numbers) are only rarely involved in food allergies.
