The Dietary Guidelines for Americans provides science-based advice to promote health and to reduce risk for major chronic diseases through diet and physical activity. Major causes of morbidity and mortality in the United States are related to poor diet and a sedentary lifestyle. Some specific diseases linked to poor diet and physical inactivity include cardiovascular disease, type 2 diabetes, hypertension, osteoporosis, and certain cancers. Furthermore, poor diet and physical inactivity, resulting in an energy imbalance (more calories consumed than expended), are the most important factors contributing to the increase in overweight and obesity in this country. Combined with physical activity, following a diet that does not provide excess calories according to the recommendations in this document should enhance the health of most individuals.
An important component of each 5-year revision of the Dietary Guidelinesis the analysis of new scientific information by the Dietary Guidelines Advisory Committee (DGAC)
appointed by the Secretaries of the U.S. Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA). This analysis is the primary resource for development of the report on the Guidelines by the Departments. The Dietary
Guidelinesand the report of the DGAC differ in scope and purpose compared to reports for previous versions of the Guidelines.The 2005 DGAC report is a detailed scientific analysis. The scientific report was used to develop the Dietary Guidelinesjointly between the two Departments and forms the basis of recommendations that will be used by USDA and HHS for program and policy development.
Thus it is a publication oriented toward policymakers, nutrition educators, nutritionists, and healthcare providers rather than to the general public, as with previous versions of the Dietary Guidelines, and contains more technical information.
The intent of the Dietary Guidelinesis to summarize and synthesize knowledge regarding individual nutrients and food components into recommendations for a pattern of eating that can be adopted by the public. In this publication, Key Recommendations are grouped under nine inter-related focus areas. The recommendations are based on the preponderance of scientific evidence for lowering risk of chronic disease and promoting health. It is important to remember that these are integrated messages that should be implemented as a whole. Taken together, they encourage most Americans to eat fewer calories, be more active, and make wiser food choices.
A basic premise of the Dietary Guidelinesis that nutrient needs should be met primarily through consuming foods. Foods provide an array of nutrients and other compounds that may have beneficial effects on health. In certain cases, fortified foods and dietary supplements may be useful sources of one or more nutrients that otherwise might be consumed in less than recommended amounts. However, dietary supplements, while recommended in some cases, cannot replace a healthful diet.
