Answer to Question 1
Nutrient density is determined by the amount of nutrients relative to the energy content of a food.A nutrient-dense food provides vitamins, minerals, and other beneficial substances with relatively few calories. Consider calcium sources, for example. Ice cream and fat-free milk both supply calcium, but a cup of rich ice cream contributes more than 350 calories, whereas a cup of fat-free milk has only 85and almost double the calcium. Fat-free milk has a high nutrient density, whereas ice cream is low in nutrient density.Among foods that often rank highin nutrient density are the vegetables, particularly the nonstarchy vegetables such as dark leafy greens (cooked andraw), red bell peppers, broccoli, carrots, mushrooms, and tomatoes.
