  • FOOD ALLERGY (FA) is an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a given food.
  • The symptoms of this disease can range from mild to severe and, in rare cases, can lead to anaphylaxis.
  • The most common food allergens are eggs, milk, peanuts, tree nuts, soy, wheat, crustacean shellfish, and fish.
  • Nonallergic food reactions, such as food intolerance, are frequently confused with FAs.
  • Food allergy is managed by allergen avoidance or treatment of symptoms.
