My daughter has her twins on a gluten free diet. I think that it internet fiction in most cases unless the children have been tested by an allergist and identified as being allergic to gluten. I do not think that it is a fix for autism, but many parents feel that it helps, including my daughter. The idea is based on the fact that many autistic children have digestive problems. Many parents feel that they have to try it because they want to try to take some action.

Certainly if a person is allergic to gluten (caelliac disease), they MUST not eat it, but that is not the only problem gluten can cause. If your body lacks the enzymes necessary to break it down, it builds up. I had my urine tested, it appears that I lack these enzymes. It appears that this is part of what is called autism. The problem with using a gluten free diet to fix such a problem (assuming that you varified that it exists) is that gluten in a lot of different foods, and it is stored in the fat. You have to exclude it consistently over a long period of time to get it out of your body. One of my relatives was tested and found to have VERY high levels of glutimorphine (from gluten) and caseimorphine (from dairy). He did improve when these were removed. With Casein, the result is very fast, drinking milk INSTANTLY causes him to flip out. Like I said, gluten is slower, but more persistent. Yes, we do have many digestive problems. Almost all of us suffer from yeast infections, for example. There are probably many things wrong with our metabolism, and the problems are different with each different person with autism. It is a "spectrum", different levels of autism, and probably different causes.
