Background: There is strong evidence supporting theories which purport that genetic connections may increase risks for autism, but the etiopathology of autism has remained undefined. In recent years, studies have focused on a diet-autism axis in an attempt to better understand nutritional contexts of autistic behavior and learning. Studies have shown that some autistic expressions may be ameliorated with a gluten free/casein free diet. A Specific CarbohydrateDietary intervention has become increasingly popular among parents of autistic children, while medical physicians have become increasingly concerned for these children’s nutritional health. Specific Carbohydrate Dietary interventions have not been scientifically evaluated.

Objective: Based on claims that the Specific CarbohydrateDiet ameliorates autistic behaviors and heals chronic gutissues, the purpose of this project is to understand theSpecific Carbohydrate Diet’s effectiveness in ameliorating autistic expressions, i.e., both behavioral andphysiological.

Design: Physiological and behavioral signs were observed in 2 children with autism. Based on the abnormal physiological and behavioral profiles, targeted dietary intervention trials using a Gluten Free/Casein Free Diet followed with a Specific Carbohydrate Diet were initiated in both autistic children.

Results: These autistic children showed significantly less behavioral and physiological problems during the SpecificCarbohydrate Diet than during the Gluten Free/Casein Free intervention. These results are consistent with the claims related to a Specific Carbohydrate Dietary intervention.

Conclusions: Based on the results of observed behavioral and physiological changes during the adherence of a SpecificCarbohydrate Dietary intervention, we hypothesize that theSpecific Carbohydrate Diet does ameliorate autistic expressions in some autistic populations.
