Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.

I have just started to explore this avenue myself. Our 3 yr old grandson who we are raising has been diagnosed with PDD/NOS and ADHD. I have found that the website www.glutenfreeinfo.com has been the easiest to follow so far. Just click on food lists and it gives you tons of choices without having to buy prepackaged foods from gluten free food suppliers. Our grandson is an extemely picky eater but from what I have read, once the kids adjust to this diet they actually begin to be less picky.
