UT Health Science Center researchers study diet and autism

Possible link between gluten, dairy products investigated

HOUSTON-(Aug. 7, 2008)—Researchers at The University of Texas Health Science Center at Houston have embarked on one of the first double-blind, clinical studies to determine whether gluten and dairy products play a role in autistic behavior as parents have anecdotally claimed.

The pilot study is one of seven current studies on autism in the Department of Pediatrics and the Department of Psychiatry and Behavioral Sciences at The University of Texas Medical School at Houston.

"There's a lot of misinformation, so that's why this study is so important," said Fernando Navarro, M.D., assistant professor of pediatrics at the medical school and lead investigator of the study. "Hundreds and hundreds of parents think this works but we need serious evidence."

Autism is a complex neurobehavioral disorder linked to early abnormalities of brain development. According to the National Institute of Neurological Disorders and Stroke, it affects up to six of every 1,000 children and is characterized by impaired social interaction, problems with verbal and nonverbal communication and unusual, repetitive or severely limited activities and interests. Researchers have discovered that there are differences in the central nervous system's anatomy and function in those diagnosed with autism, but the cause of the disorder is unknown. Experts theorize it may be a combination of genetics and environment.
