Gluten-free diet can also experience adverse effects of wheat as result of a wheat allergy. Gastrointestinal symptoms of wheat allergy are similar to those of coeliac disease and non-coeliac gluten sensitivity, but there is a different interval between exposure to wheat and onset of symptoms. Wheat allergy has a fast onset (from minutes to hours) after the consumption of food containing wheat and could be anaphylaxis. The management of wheat allergy consists of complete withdrawal of any food containing wheat and other gluten-containing cereals. Nevertheless, some people with wheat allergy can tolerate barley, rye or oats. Gluten ataxia is an autoimmune disease
Wheat allergy comes from the progenitor species "Aegilops speltoides". This indicates that nascent mutations on the B genome of wheat are from a small number of cultivated Triticeae species. Recent study of WDEIA shows that both aspirin and exercise increase the presence of gliadin in the blood stream and the chronic induced response may extend to NSAIDs, MSG, Benzoate and other synthetic chemical food additives. Baker's allergy has a ω-gliadin component and thioredoxin hB component. In addition, a gluten-extrinsic allergen has been identified as aspergillus amylase, added to flour to increase its baking properties. Contact sensitivity, atopic dermatitis, eczema, and urticaria appear
