Metabolic interventions in Autism Spectrum Disorder

Metabolic interventions including special diets and supplements are commonly used in Autism Spectrum Disorder (ASD). Yet little is known about how these interventions, typically initiated by caregivers, may affect metabolic function or the core symptoms of ASD. This review examines possible direct and indirect roles for metabolism in the core symptoms of ASD as well as evidence for metabolic dysfunction and nutritional deficiencies. We also discuss some of the most popular diets and supplements used in our patient population and suggest strategies for discussing the utility of these interventions with patients, families, and caregivers.
