Document Summary
It is easier to build an adequate and healthy diet around nutrient-dense foods than around empty calorie foods: eating a low energy-dense diet allows you to eat a larger volume of food, all while maintaining energy balance. Fat, sugar, and alcohol tend to increase energy density. Fluid (water) and fiber tend to decrease energy density. For an equal number of calories, portion size decreases as energy-density increases: high energy-dense foods are foods with a high number of calories for their weight. Nutrient density: nutrient density is the nutrient contribution per kcal in a food. The typical american diet does not align with recommended limits or goals: excessive amount of energy-dense foods. Dietary guidelines for americans: updated every five years, evidence-based guidelines to promote health and reduce risk for major chronic disease.
