In this book, author Joe Schwarcz addresses foods such as tomatoes, acai berries, curry and soy; additives like nitrites, artificial sweeteners, vitamins and fluoride; contaminants including pesticides, hormones, trans fats and dioxins; and what he suspects to be food or diet fads. Schwarcz contends there are no magical foods, but that a diet of mostly vegetables, fruits, whole grains and low-fat dairy products and moderation are key to good health.
