This lecture explores the role of dietary interventions in the recovery and management of autism spectrum disorder (ASD), focusing on four prominent healing diets: the Specific Carbohydrate Diet (SCD), Paleo Diet, GAPS, and the Autoimmune Protocol Diet (AID). Each diet is grounded in unique principles that aim to improve gut health, reduce inflammation, and support neurological function—key areas of concern in ASD. The SCD eliminates complex carbohydrates to promote healthy gut flora, while the Paleo Diet emphasizes whole, unprocessed foods to reduce inflammation. The GAPS Diet focuses on gut and brain healing, and the AID is a more restrictive regimen designed to calm autoimmune responses and heal the gut. By examining the science behind these diets and their potential benefits, this lecture provides insights into how diet is the primary step in healing and how to get started with tips and inexpensive hacks to accelerate healing.
