Essentially none.: All foods are capable of becoming an allergen. However, the most common foods to cause allergy are peanut, tree nuts, shellfish, wheat, egg, milk, and soy.

Common groups include gluten, dairy products, and night-shade foods. Search the internet for specific foods to avoid in each of these groups, then try removing them from your diet for one week at a time.
