The team -- which included Laura Cousino Klein, associate professor of biobehavioral health and human development and family studies -- asked 387 parents or primary caregivers of children with ASD to complete a 90-item online survey about their children's GI symptoms, food allergy diagnoses, and suspected food sensitivities, as well as their children's degree of adherence to a gluten-free, casein-free diet. The team's results appeared online this month in the journal Nutritional Neuroscience.
