Definition of wheat allergy

  1. Definition of wheat allergy
Weizenfrei, Weizenallergie

Food Hypersensitivity is an umbrella term used to describe adverse reactions to foods, including wheat.

Food hypersensitivity includes Food Allergy (IgE and non-IgE mediated) and food intolerance. Wheat allergy refers to an adverse immune system response involving immunoglobulin E (IgE) antibodies. A wheat intolerance is an adverse reaction that is not immune mediated. The mechanisms of wheat allergy can be divided into IgE antibody mediated wheat allergy (characterized by reactions occurring within minutes to 2 hours of eating or inhaling the allergen) and non-IgE antibody mediated wheat allergy (characterized by reactions occurring between 2-48 hours of longer) [1].
