Parents certainly know just how much what your child eats can affect his behavior and that goes deeper than something like too much sugar before bedtime. Families with autistic children are cutting certain proteins from their children's diet to see if there is a reduction in the symptoms. Doctors using this treatment say just a small change can equal big results for children with autism.

The Esker's of Weston are trying the Bio-Medical Approach with their two year old son Troy. "Since January, no dairy no meat, no gluten," says Troy's mom Jamie. "We didn't notice a tremendous change we are going to try taking him off it for a while to see if we notice any regression, says Troy's father Cory.

Doctor Kyle Vandyke, says children with Autism often have problems digesting the Casein found in dairy products and the Gluten found in wheat. He recommends parents try the GFCF Diet. "Doing the diet is free a lot of kids are getting tremendous gains from doing the GFCF Diet and it's free and you can do it without a doctor."

Dr. Vandyke has a child with severe Autism. He's been a doctor for nearly 15 years and is a trained a DAN Practitioner. "DAN" stands for "Defeat Autism Now" - it's a specialty that views Autism as a treatable condition. "If you actually address some of these GI issues which are so prominent in these kids, when you treat the GI stuff the kids start to get better. Says Dr. Vandyke."

In addition to a change in diet Dr. Vandyke says the Bio-Medical Approach also includes Methyl B-12 shots. "It's a form of B-12 vitamin, that has Methyl added to it. We frequently see kids get steadily better on that. Others get dramatic responses where you give them the B-12 shot and they start talking in sentences the next day or have had terrible aggression problems that just go away." Says Dr. Vandyke.

Dr. Vandyke says the main stream medical community hasn't fully embraced the biomedical approach, but says that time is coming as as more parents see results. "I encourage all parents, don't believe what I'm saying look around on your own do the diet try taking milk away from your child for a week. Try taking wheat away for a couple of weeks and just see what happens. That's what convinced me and my son. Just talking away these things I saw dramatic changes."

As for the Esker family, they aren't giving up on the biomedical approach either. "There are other diets we are going to be trying. We just had some blood work done to find out food allergies, and what else he could be allergic to," says Cory Esker.
