Exercise-Induced Food Allergy

At least one situation may require more than simply eating food with allergens to start a reaction: exercise-induced food allergy. People who have this reaction only experience it after eating a specific food before exercising. Some people get this reaction from many foods, and others get it only after eating a specific food. As exercise increases and body temperature rises, itching and light-headedness start and allergic reactions such as hives may appear and even anaphylaxis may develop.
The management of exercised-induced food allergy is simple — avoid eating for a couple of hours before exercising.
