What does nutrient density refer to?

Nutrient density refers to the ratio of the amount of macro- and micronutrients in a food item relative to its weight or calorie content. Foods that are nutrient-dense provide a high level of nutrients—such as vitamins, minerals, proteins, and healthy fats—while being relatively low in calories. This concept is important in nutrition because it helps individuals identify foods that contribute to their overall health and well-being without excessive caloric intake.

For example, vegetables and fruits typically have a high nutrient density because they are rich in essential nutrients but contain fewer calories. Conversely, foods that are high in calories but low in nutrients, like many processed snacks, would be considered low nutrient density. Understanding nutrient density is vital for making healthier food choices and ensuring that one’s diet is balanced and nutritious.
