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
Gluten-free, casein-free diet cream topping, which use casein to provide texture. Although advocates of the GFCF diet often recommend total elimination of dairy from the diet, whey protein is a different milk protein from casein. Gluten-free, casein-free diet Gluten-free casein-free diet (GFCF diet), also known as gluten-free dairy-free diet (GFDF diet), is a diet that does not include the proteins gluten (found most often in wheat, barley, and rye), and casein (found most often in milk and dairy products). Despite an absence of scientific evidence, there have been advocates for the use of this diet as a treatment for autism and related conditions.
