Nutrition density refers to the amount of essential nutrients—such as vitamins, minerals, and other beneficial compounds—present in a food in relation to its calorie content. Foods that are considered nutrient-dense offer a high level of nutrients for relatively low calories, which is beneficial for maintaining a healthy diet. For example, spinach and broccoli are nutrient-dense because they provide a wealth of vitamins and minerals without being high in calories.

This concept emphasizes the quality of food choices rather than just the quantity of calories consumed. When aiming to improve dietary habits, focusing on nutrient-dense foods can support overall health, weight management, and nutrient adequacy. Foods low in nutrient density, on the other hand, may be high in calories but offer little nutritional benefit, often referred to as "empty calories," such as sugary snacks and processed foods. This distinction is crucial for individuals looking to make healthier dietary choices, ensuring their diet is rich in essential nutrients while being mindful of caloric intake.
