The books of Lendon Smith have some greatadvice on food. Heis a   pediatrician and nutritionist. Two I haveread areFeed Yourself Right and The Low Stress Diet. Try a used bookstore or www.half.com. He talks about how eating habits can lead to all sorts of disease and discomfort, not just overweight-some acue symptoms, some gradual or chronic. Based on his advice I started taking calcium supplements and they eased a lot   if the sympotoms of stress I was experiencing (insomnia, tension headaches, eyelid muscles twitching, etc.)

He speaks of his own struggles with food sensitivities etc. Says when he stopped eating cookies everyday many annoying symptoms disappeared. He also says if he ate a sandwich every day he'd gain ten pounds in a week...but he does enjoy bread once in a while. He also believes every individual has to find the food that works for them. Ethnic background can be a good indicator. Eat what your ancestors are known for. In the case of Mediterranean and Asian diets, this can be very healthful and very tasty!
