M.F.
T.,
As luck would have it, I was just reading TONIGHT a book called "Disease Proof Your Child" by Joel Fuhrman, M.D.
He has some dietary recommendations for attention problems and allergies. One of the main things he supports is a diet rich in omega-3 fats, which are essential for brain function and development. Here's what he suggests (combined from his diets for ADHD and allergies):
A high-nutrient, vegetable, nut, and fruit-based diet (he includes recipes in the book)
One tablespoon of ground flax seeds daily (easily added to oatmeal, shakes, applesauce, etc.)
At least an ounce of raw walnuts daily (for the healthy fats)
DHA supplement (100-600mg daily)
No processed foods, dairy, or trans fat
Little or no oils (essential fats are supplied from raw nuts and DHA supplementation)
Multivitamin without Vitamin A or isolated beta-carotene (this was in his dietary guidelines for children with allergies, but not in the list for ADHD)
Some children must also avoid gluten (from wheat) and casein (from dairy). This one is just in the ADHD recommendations.
As far as finding gluten-free foods, I've seen tons of them at Whole Foods, The Cupboard (in Denton) and Sprouts Farmer's Market (in Flower Mound). There are cereals, snack bars, cake and muffin mixes, frozen waffles, etc. The foods at these places are expensive, so you might need to make room in your grocery budget.
