Gluten exorphins are a group of opioid peptides which are formed during digestion of the gluten protein. It has been hypothesized that people with autism and schizophrenia have abnormal leakage from the gut of these compounds, which then pass into the brain and disrupt brain function.[1] This is partly the basis for the gluten-free, casein-free diet. Two clinical studies of autism patients who followed this diet have found no evidence of benefit.[2][3] Another found evidence of benefit.[4] Another study suggested the diet may present a greater risk to brain development.[5]
