Effect of a Dietary Intervention on Autistic Behavior

Abstract

Autistic syndromes are characterized by impaired social, communicative, and imaginative skills. Urinary peptide abnormalities, in part due to gluten and casein, have been detected in some individuals With autism. These abnormalities reflect processes With opioid effect, Which may explain the behavioral abnormalities seen in autism. The aim of this single-blind, controlled study Was to evaluate the effect of a gluten-free and casein-free diet for children With autism and urinary peptide abnormalities. Observations and tests Were carried out With the 20 participanting children before they Were randomly assigned to either the diet or the control group. The experimental period Was 1 year, after Which observations and tests Were repeated. Significant reduction of autistic behavior Was registered for participants in the diet group, but not for those in the control group.
