What is nutrient density?

Nutrient density refers to the amount of beneficial nutrients a food contains relative to its calorie content. Foods that are nutrient-dense provide a high level of vitamins, minerals, and other beneficial compounds without a corresponding high calorie count. This is important for maintaining a healthy diet, as it encourages the consumption of foods that offer more health benefits per calorie, supporting overall wellness and preventing chronic diseases. For example, vegetables, fruits, whole grains, and lean proteins are often considered nutrient-dense because they deliver significant nutrients while being lower in calories. In contrast, foods that are high in calories but low in nutrients—like sugary snacks or processed foods—have low nutrient density and can contribute to poor health outcomes. Thus, understanding nutrient density helps individuals make better dietary choices that prioritize health and nutrition.
