Currently, more than 3 percent of American adults suffer from food allergies. Many of the allergens responsible for these numbers are so called pan-allergens, or allergens that are present in many foods. For example, roughly 12 million are allergic to proteins present in almost all shellfish. Another common allergy caused by a pan allergen is peanut and nut allergies. 3 million are allergic to peanuts or some other tree nut.
