Several years ago when our youngest son was first diagnosed with autism, we read all the ideas people had about what causes it and how to cure it. So we started going gluten free. The gluten free products available five years ago were, well just plain bad. Fast forward to today as we are working to see if our oldest son has a gluten issue we are finding many more gluten free products and have been surprised that the taste and texture have improved.
So far we really like the Betty Crocker Gluten Free Brownies and Sugar Cookies. (http://www.bettycrocker.com/products/glutenfree)
