What does nutrient density measure?

Nutrient density measures the amount of nutrients found in a food relative to its calorie content. This concept is essential in evaluating the healthfulness of foods, as it helps to identify which foods provide the most vitamins, minerals, and other beneficial compounds for the least amount of calories. Foods that are high in nutrient density are typically rich in essential nutrients like vitamins and minerals while being lower in calories, making them ideal choices for a balanced diet.

For example, vegetables, fruits, whole grains, and lean proteins often have high nutrient density because they provide significant health benefits with fewer calories. Understanding nutrient density is crucial when planning a diet, especially for individuals looking to manage weight while ensuring they meet their nutrient needs.

On the other hand, the other options do not accurately reflect what nutrient density measures. The quality of protein in foods pertains specifically to the biological value of protein sources, flavor and taste refer to sensory attributes of food, and cooking methods influence food preparation but do not directly relate to the nutrient content per calorie.
