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 gluten (food) imported to the West in 1969 by the American company Erewhon. Wheat gluten is also called seitan (, ; Japanese: セイタン), mianjin (Chinese: 麵筋), milgogi(Korean: 밀고기), wheat meat, gluten meat, or simply gluten.
