Is autism curable?

This seems sort of irresponsible to me. Jenny McCarthy's son, Evan, has autism. His actress mom has been a very dedicated advocate in trying to find a cure and raising money for autism and I applaud her for that, but this newest story makes me think she may end up doing more damage than good.

McCarthy tells the newest edition of Us Magazine that she has cured her son of his autism with diet. I'm sure there's more to her miracle "cure," but diet seems to be the main thing. I guess all cures have to start somewhere, and some cures come from very strange sources, but to go on a national magazine claiming to have cured her son of autism seems maybe a bit premature.
