Wheat allergy is an allergy to wheat that typically presents as a food allergy, but can also be a contact allergy resulting from occupational exposure. The exact mechanism of this allergy is not yet clear. Wheat allergy may be immunoglobulin E-mediated or not, [1] and may involve a mast cell response. [2]
True wheat allergies are very rare; it is estimated to effect 0.1%-2.2% of individuals depending on region. [60] The allergy does not commonly persist into adolescence. Gluten-free foods are safer for wheat allergic patients but they still may theoretically contain wheat's other allergenic proteins. [61]
The IgE antibodies are more typically found in allergy-related conditions such as urticaria, asthma, and wheat-dependent exercise-induced anaphylaxis. The target of the most allergenic antibodies is ω-5 gliadin, [8] which is encoded by the Gli-1B gene found on the B haplome (Aegilops speltoides derived) of wheat. [9]
Gastrointestinal symptoms of wheat allergy are similar to those of coeliac disease and non-celiac 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. [15] [45] The ...
About 75% of children who have allergies to milk protein are able to tolerate baked-in milk products, i.e., muffins, cookies, cake, and hydrolyzed formulas. [99] About 50% of children with allergies to milk, egg, soy, peanuts, tree nuts, and wheat will outgrow their allergy by the age of 6.
For those who must carefully dodge products because of wheat, egg, gluten or milk allergies or sensitivities -- including those with Celiac's Disease -- check your freezer for Van's Wheat Free ...

[32] As with most allergies, a wheat allergy causes the immune system to respond abnormally to a component of wheat that it treats as a threatening foreign body. This immune response is often time-limited and does not cause lasting harm to body tissues. [77] Wheat allergy and celiac disease are different disorders.
