Introduction

Because issues related to diet and physical activity are so important for disease risk, it is certainly possible that developing preventive methods that focus solely on these parameters also could have a huge impact on morbidity and mortality from disease and, of course, on the economic issues as well. This is not to say that pharmacological-and nutraceutical-based management of disease risks has no place in prevention. They can be very important in reducing genetic-or environmentalbased risks as well as in correcting serious dietary deficiencies, regardless of the cause. They are, however, outside the scope of this chapter.
