Are you aware of any research being done on diet and its affect on children w/ autism? If so, what has been learned?

“Got Questions?” is a new weekly feature on our blog to address the desire for scientific understanding in our community.  We received over 3000 responses when we asked what science questions were on your mind. We answered a few here and the Autism Speaks Science staff will address the other themes we received in this weekly post.

To date, there have only been a few published rigorous clinical trials examining the efficacy of dietary treatment (specifically, the gluten-free, casein-free diet) for improving symptoms of ASD. These have been negative or inconclusive, but were based on very small samples. More recently, Dr. Susan Hyman at the University of Rochester reported the results of a double-blind, randomized trial in which children who were on the diet were challenged with foods containing casein and gluten. Dr. Hyman examined factors such as attention, sleep and the stool of 22 children with ASD both challenged and unchallenged and found no benefit from the diet. Dr. Hyman stressed that her findings don’t rule out the possibility that there may be subgroups of children who benefit. Autism is a very heterogeneous condition. More research is needed.
