What does the term "nutrient density" refer to?

Nutrient density is defined as the amount of nutrients a food provides relative to its calorie content. Foods that are high in nutrient density offer a greater variety of essential nutrients such as vitamins, minerals, and other beneficial compounds, while being lower in calories. This concept is important in nutrition and diet therapy because it emphasizes the value of choosing foods that contribute more nutrients per calorie consumed, promoting overall health and helping to meet dietary needs without excessive caloric intake.

For example, vegetables, fruits, whole grains, and lean proteins are typically nutrient-dense because they provide vitamins, minerals, and other nutrients without adding too many calories. Conversely, foods that are high in calories but low in nutrients, such as sugary snacks or fried foods, would be considered low in nutrient density. Understanding this concept helps individuals make better dietary choices that contribute to health and wellness.
