Is there a link between gluten, casein, and autism? Several studies have been conducted on whether removing casein and gluten from a diet relieves symptoms of autism in children. The Autism Network for Dietary Intervention (ANDI) has compiled a comprehensive list of summaries of these studies. All you need to know? While on this diet, children with autism have repeatedly shown improvement in social and communicative abilities. But the results aren’t permanent: when the diet ends, autistic traits reappear. And everyone’s body reacts differently—just go to ANDI’s great list of parents’ questions and complaints about trying this diet on their children.
