Grain Brain: The Surprising Truth About Wheat, Carbs, and Sugar–Your Brain’s Silent Killers —written by neurologist David Perlmutter, MD.
An interesting point the author makes is…we all know diet can affect various aspects of our body, but we rarely think about how diet affects our brain. The author makes a compelling case for eliminating wheat from your diet (so much so, I have given it up!).
If you are interested in reading about a gluten free diet, or are curious just to know how diet can affect your brain, I highly recommend this book.
As to students, many children (though not all) on the autism spectrum have responded well and have shown improvement after being on a gluten free diet.
