Study summary

We hypothesize that in children with autism dietary antigens can change the intestine, making it "leaky" and then affecting the brain changing their behavior.

Read the detailed description

Subjects in 2 different diets (gluten/dairy and placebo) will be monitored for changes in intestinal permeability (urine lactulose mannitol ratio) and behavior (psychometric testing).
