I have the book Brain Allergies, too, and would recommend it to anyone who has neurologic/behavioural symptoms that might be related to food, environment, or chemical allergies. He does talk about gluten as being a top food offender.

Chapter two of the book also contains one of my favorite quotes:
"One must be taught to suspect, for if one does not suspect, he does not test, and if he does not test, he does not know" H.J. Rinkel

This seemed especially pertinent to me when my daughter presented with seizures, and I suspected autoimmune disease, allergy, and nutritional deficiency (because she had dental enamel defect, and dented finger nails and I had just been dx'd B12 deficient), but the doctor only wanted to treat with AED's and not worry about the "why's" or do any testing for possible autoimmunity, food sensitivity, or nutritional deficiency!
