Oat cereals. Celiac disease (coeliac disease) is a permanent intolerance to certain gluten proteins in genetically predisposed people, having a prevalence of about 1% in the developed world. Gluten is present in wheat, barley, rye, oat, and all their species and hybrids and contains hundreds of proteins, with high contents of prolamins. Oat prolamins, named avenins, are similar to gliadins found in wheat, hordeins in barley, and secalins in rye, which are collectively named gluten. Avenins toxicity in celiac people depends on the oat cultivar consumed because of prolamin genes, protein amino acid sequences, and the immunoreactivities of toxic prolamins which
Wheat allergy cause. If symptoms are alleviated by immunosuppressant drugs, such as Prednisone, an allergy-related cause is likely. If multiple symptoms associated with wheat allergies are present in the absence of immunosuppressants then a wheat allergy is probable. Management of wheat allergy consists of complete withdrawal of any food containing wheat and other gluten-containing cereals (gluten-free diet). Nevertheless, some patients can tolerate barley, rye or oats. In people suffering less severe forms of wheat-dependent exercise induced anaphylaxis (WDEIA), may be enough completely avoiding wheat consumption before exercise and other cofactors that trigger disease symptoms, such as nonsteroidal anti-inflammatory drugs and alcohol.
