Food allergy is an immune system overreaction or repetitive eating of a trigger food. Even tiny amounts of the allergy-causing food can trigger reactions like digestive problems, skin itching, and/or hives and breathing difficulties. In some, it can cause severe symptoms or even a life-threatening reaction is known as anaphylaxis. 

Food allergy is more common in infants and children. While there's no cure, some children outgrow their food allergy. It's easy to confuse a food allergy with a much more common reaction known as food intolerance. While bothersome, food intolerance is a less serious condition that does not involve the immune system.
