What is exercise-induced food allergy?

Exercise can induce an allergic reaction to food. The usual scenario is that of a person eating a specific food and then exercising. As he exercises and his body temperature increases, he begins to itch, gets lightheaded, and soon develops the characteristic allergic reactions of hives, asthma, abdominal symptoms, and even anaphylaxis. This condition has been referred to as food-dependent exercise-induced anaphylaxis (FDEIA) and is most common in teens and young adults. The cure, actually a preventive measure, for exercise-induced food allergy is simple -- not eating for at least two hours before exercising.

What conditions have mistakenly been attributed to food allergy?

Studies have shown that individuals who are prone to migraines can have their headaches brought on by histamine, which is one of the compounds that mast cells produce in an allergic reaction. The theory that food allergies can cause migraine headaches, however, is unproven. There is also inadequate scientific evidence to support the claims that food allergies can cause or aggravate rheumatoid arthritis, osteoarthritis, tension-fatigue syndrome, cerebral allergy (headaches and difficulty concentrating), environmental-toxic reactions, or hyperactivity in children.
