Coeliac disease microscopic colitis, gluten ataxia, psoriasis, vitiligo, autoimmune hepatitis, dermatitis herpetiformis, primary sclerosing cholangitis, and more. Coeliac disease is caused by a reaction to gliadins and glutenins (gluten proteins) found in wheat, and similar proteins found in the crops of the tribe Triticeae (which includes other common grains such as barley and rye) and the tribe Aveneae (oats). Wheat subspecies (such as spelt, durum and Kamut) and wheat hybrids (such as triticale) also induce symptoms of coeliac disease. A small number of people with coeliac react to oats. Oats toxicity in coeliac people depends on the oat cultivar consumed because of
Wheat gluten (food) 蛋 (tan, from 蛋白 (tanpaku, "protein")). The meaning of the word "seitan" has undergone a gradual evolution. The initial product, imported from Japan in 1969 was a very salty seasoning, the color of soy sauce, sold in a small glass jar or plastic pouch, to be used as a seasoning for brown rice. The name gradually came to refer to any wheat gluten seasoned with soy sauce. The people most responsible for this change are Nik and Joanne Amartseff, who invented Tan Pups in 1972 and John Weissman, who in 1974 invented Wheatmeat (first meatballs then cutlets made of seitan)
