A food allergy occurs when the body mistakes a food item for a harmful substance, and the immune system creates antibodies to protect itself. Once this mistaken identity occurs, every time a person eats that food the body will release histamine and other chemicals, triggering an allergic reaction. This response can affect the respiratory, gastrointestinal and cardiovascular systems. It can also cause a skin reaction.
