calorie balance. The balance between calories consumed in foods and beverages and calories expended through physical activity and metabolic processes.
eating pattern. The combination of foods and beverages that constitute an individual’s complete dietary intake over time.
nutrient dense. Nutrient-dense foods and beverages provide vitamins, minerals, and other substances that may have positive health effects with relatively few calories. The term “nutrient dense” indicates that the nutrients and other beneficial substances in a food have not been “diluted” by the addition of calories from added solid fats, added sugars, or added refined starches, or by the solid fats naturally present in the food. Nutrient-dense foods and beverages are lean or low in solid fats, and minimize or exclude added solid fats, sugars, starches, and sodium. Ideally, they also are in forms that retain naturally occurring components, such as dietary fiber. All vegetables, fruits, whole grains, seafood, eggs, beans and peas, unsalted nuts and seeds, fat-free and low-fat milk and milk products, and lean meats and poultry—when prepared without adding solid fats or sugars—are nutrient-dense foods. For most Americans, meeting nutrient needs within their calorie needs is an important goal for health. Eating recommended amounts from each food group in nutrient-dense forms is the best approach to achieving this goal and building a healthy eating pattern.
