Gluten immunochemistry in foods that have added gluten, such as wheat bread, food pastes. The major gluten proteins that are involved in coeliac disease are the α-gliadin isoforms. Alpha gliadin is composed of repeated motifs that, when digested, can be presented by HLA-DQ molecules. DQ2.5 recognizes several motifs in gluten proteins, and therefore HLA-DQ can recognize many motifs on each gliadin (see Understanding DQ haplotypes and DQ isoforms on the right) However, numbers of different proteins from the grass tribe Triticeae have been found to carry motifs presented by HLA DQ2.5 and DQ8. Wheat has a large number of these proteins because
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.
