Wheat allergy is an allergic reaction to foods containing wheat. It's one of the more common food allergies in children. Wheat can be found in many foods, including some you might never suspect, such as breads, cakes, breakfast cereals, pasta, crackers, beer, soy sauce and condiments, such as ketchup.
Avoiding wheat is the primary treatment for wheat allergy. Medications may be necessary to manage allergic reactions when you accidentally eat wheat.
Wheat allergy may sometimes be confused with celiac disease, but these conditions are different. A wheat allergy generates an allergy-causing antibody to proteins found in wheat. But, one particular protein in wheat — gluten — causes an abnormal immune system reaction in the small intestines of people with celiac disease.
