Overview Farzan explains that a food allergy is an immune-mediated reaction to the food. The most common is an Immunoglobulin E (IgE)-mediated reaction. IgEs are allergic antibodies. They cause an immediate reaction when chemicals, like histamine from mast cells, are released. Food allergies can be fatal, unlike a food intolerance or sensitivity. In extreme cases, ingesting or even touching a small amount of the allergen can cause a severe reaction. Symptoms of food allergy include: skin reactions, like hives, swelling, and itching; anaphylaxis, including difficulty breathing, wheezing, dizziness, and death; digestive symptoms

Food Allergies vs. Food Intolerance Food allergies and food intolerance are sometimes confused with each other, but they are quite different in terms of their origin, symptoms and treatment. True allergic reactions to food involve the body's immune system. When the body identifies a food as harmful, it produces antibodies directed against that food. The next time the food is consumed, the body mounts an immune response with the release of histamine and other chemicals that trigger allergic symptoms. A common example of a food allergy is to peanuts. With a food allergy, symptoms may occur almost immediately or up to hours after consuming the particular food. These symptoms may affect the respiratory system, gastrointestinal tract, cardiovascular system, or the skin.
