Researchers at the University of Texas Houston are embarking on a study to test the theories surrounding gluten free, cassein free, and dairy free diets and their effect on the autistic mind and body. "There's a lot of misinformation, so that's why this study is so important," said Fernando Navarro, M.D., assistant professor of pediatrics at the medical school and lead investigator of the study. "Hundreds and hundreds of parents think this works but we need serious evidence."
