For years, parents have noticed a link between their child’s diet and his or her symptoms of autism. Scientists have identified gluten (found in wheat and grains) and casein (found in milk products) as contributors to behaviors seen in children with autism. Eliminating these substances from the diet has been shown in many children to lessen the symptoms of autism.
The chemical or physiological mechanism is not well understood although recently studies have begun to identify just how gluten and casein effect children with autism. It appears that the body converts these substances into chemicals called “opiates.” These chemicals, which include such drugs as morphine, can affect brain development. Through blood and urine tests, these chemicals have been found in the blood and urine of children with autism who consume gluten and casein. Eliminate gluten and casein and their chemical residues disappear.
Because of food allergies, such as celiac disease, many children (who do not have autism) eat a gluten and casein free diet. These diets are both safe and nutritionally complete. Many books and resources are available to guide parents in choosing a gluten and casein free diet.
