What does the term 'nutrient density' refer to?

Nutrient density refers to the amount of nutrients a food provides relative to its calorie content. Foods that are considered nutrient-dense supply a high level of vitamins, minerals, and other beneficial compounds while being lower in calories. This concept is essential in making healthy food choices, as nutrient-dense foods can help meet nutritional needs without excessive calorie intake, which is particularly important for maintaining a healthy weight and preventing chronic diseases. For example, fruits, vegetables, whole grains, and lean proteins are typically nutrient-dense options, providing essential nutrients without adding too many calories to the diet. Understanding nutrient density aids in evaluating food choices beyond just calorie count, focusing on the overall health benefits that come from those choices.
