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
Rye a serious medical condition known as ergotism. Ergotism can cause both physical and mental harm, including convulsions, miscarriage, necrosis of digits, hallucinations and death. Historically, damp northern countries that have depended on rye as a staple crop were subject to periodic epidemics of this condition. Such epidemics have been found to correlate with periods of frequent witch trials, such as the Salem witch trials in Massachusetts in 1692. Rye grain is refined into a flour. Rye flour is high in gliadin but low in glutenin. It therefore has a lower gluten content than wheat flour. It also contains a higher
