Dietary Guidelines for Americans 2010: implications for cardiovascular disease.

The 2010 Dietary Guidelines for Americans (DGA) provides science-based advice to promote health and reduce risk of major chronic diseases by diet and physical activity. The primary emphasis is on food-based recommendations that meet energy and nutrient needs. The DGA is made in the context of a total diet designed to reduce the incidence and prevalence of overweight and obesity. In addition, the DGA also targets cardiovascular disease (CVD) risk reduction. DGA recommends nutrient-dense foods including fruits and vegetables, whole grains, low-fat dairy, lean protein foods including seafood, and vegetable oils. This dietary pattern beneficially affects blood lipids and other CVD risk factors. Foods and nutrients to limit include solid fats (saturated fatty acids, trans-fatty acids), dietary cholesterol, added sugars, refined grains, and sodium. Healthy dietary patterns that emphasize nutrient-dense foods will significantly benefit public health, in part, by reducing CVD risk.
