Dietary guidelines are designed to suggest foods and food patterns that provide all the nutrients and bioactive compounds our bodies need, while avoiding those we don’t need (like too much sodium, starch, added sugars, and unwanted additives).

MyPlate, based on the Dietary Guidelines for Americans, recommends filling half our plates with fruits and vegetables, about a quarter with grains, and about a quarter with lean protein. “When following MyPlate, the Tufts Health & Nutrition Letter recommends meeting the grain component with minimally processed whole grains, and eating plenty of nuts, seeds, fish, and poultry to maximize healthy fats, proteins, and other nutrients,” says Dariush Mozaffarian, MD, DrPH, dean of the Friedman School and editor-in-chief of Tufts Health & Nutrition Letter.
