Wheat allergy is an allergic reaction to foods containing wheat, one of the top eight food allergens in the United States. Allergic reactions can result from eating wheat, but also, in some cases, by inhaling wheat flour. Wheat can be found in many foods, including some you might not suspect, such as beer, soy sauce and ketchup.
Avoiding wheat is the primary treatment for wheat allergy. Medications may be necessary to manage allergic reactions if you accidentally eat wheat.
Wheat allergy sometimes is confused with celiac disease, but these conditions differ. A wheat allergy generates an allergy-causing antibody to proteins found in wheat. In people with celiac disease, a particular protein in wheat — gluten — causes an abnormal immune system reaction.
