Opinions? Casien-Free, Gluten-Free

Aidan's speech pathologist, Debbie, lent me a book called "Eating for Autism". The book is a 10-step program to getting your autistic child on a healthier eating regimen including the Casien-Free Gluten-Free diet. So far our family is on the first step which is slowly replacing certain foods in our kitchen with healthier alternatives. The items we have to get rid of are anything containing artificial flavors, artificial sweeteners, artificial colors, and preservatives. The next time you look in your pantry, take a look at just how many of your food items contains one or more of these things! We decided to try this diet after the psychiatrist made a comment about putting Aidan on medicine. My husband and I are NOT big medication people and we want to exhaust any other options, within reason, before deciding on medication. We've heard both negative and positive opinions on the Casien-Free Gluten Free diet and the cost of the special foods are already weighing heavy in our pockets. We would like feedback on the diet and whether or not you think it would be worth pursuing further.
