Whole grain consumption of whole grain and the claimed effects considered in this opinion." In genetically susceptible people, gluten (proteins found in wheat, barley, rye, oat, and related species and hybrids) can trigger coeliac disease. Coeliac disease affects about 1% of the general population in developed countries. There is evidence that most cases remain undiagnosed and untreated. The only known effective treatment is a strict lifelong gluten-free diet. While coeliac disease is caused by a reaction to wheat proteins, it is not the same as a wheat allergy. Other diseases triggered by eating gluten are non-coeliac gluten sensitivity, (estimated to affect 0.5%
Gluten conditions often practice gluten-free diets. The occurrence of oat avenin toxicity depends on the oat cultivar consumed, because the immunoreactivities of toxic prolamins are different among oat varieties. Also, many oat products are cross-contaminated with other gluten-containing cereals. Gluten is a protein complex that accounts for 75–85% of the total protein in bread wheat. In home or restaurant cooking, gluten is prepared from flour by kneading the flour under water, agglomerating the gluten into an elastic network known as a dough, and then washing out the starch. Starch granules disperse in low-temperature water, and the dispersed starch is sedimented and
