An altered immunological reaction to a food substance to which people typically do not react. A food allergy is a hypersensitivity to a certain food or foods. Allergy to food is similar to that to other environmental allergens [substances (antigens) foreign to the body that cause an allergic response], such as pollens, but there are additional specific risks, symptoms, and immunological mechanisms. As many as 8% of children and 4% of adults experience food allergy symptoms (Fig. 1). Annually, in the United States, about 200,000 people require emergency medical treatment, and an estimated 150–200 people die from allergic reactions each year.
