Food-dependent exercise-induced anaphylaxis (FDEIA) is a special form of food allergy where a food-intake alone does not induce any symptoms. Anaphylaxis occurs only when triggering factors such as exercise or aspirin-intake are added after ingestion of the causative food.The most frequent causative food in FDEIA in Japan is wheat. Both exercise and aspirin-intake facilitate allergen absorption from the gastrointestinal tract.
80% of the patients with wheat-induced FDEIA have IgE reacting to omega-5 gliadin and the remaining of the patients to high molecular weight glutenin (HMW-glutenin).
