I eat gluten free and Whole Foods is amazing! They have an enormous selection. Central Markets does too but they are only in certain areas. Trader Joes is another. Just google supermarkets in your area and read about them. If they call themselves "health food" stores or "organic" then you have a winner. Good luck on going gluten free! Whole foods also supplies a gluten free list of their products at the customer service desk and provides someone to show you around and help you out.
