Understanding Nutrient Density
Key Definitions
Nutrient Density – The ratio of the amount of a nutrient in foods to the energy provided by these same foods.
Nutrient-Dense Foods – Foods that provide substantial amounts of vitamins, minerals and other nutrients with relatively few calories.
Low Nutrient-Dense Foods – Foods that supply calories but relatively small amounts of micronutrients (sometimes none at all).
Nutrient-Rich – A term developed through consumer research to describe the concept of nutrient density. Research shows that consumers respond well to this term and to the positive approach to food choices it represents.1,2
Nutrient-Rich Foods – A consumer-friendly way to describe nutrient-dense foods including those from the five basic food groups, such as:
- Whole, fortified and fiber-rich grain foods
- Vibrantly colored vegetables and potatoes
- Brightly colored fruits and 100% fruit juices
- Low-fat and fat-free milk, cheese and yogurt
- Lean meats, skinless poultry, fish, eggs, beans and nuts
Nutrition Profiling – The science of ranking or classifying foods based on their nutrient composition.
Nutrient Rich Foods Index – A scientifically valid system for ranking foods and beverages based on their contents of nine nutrients to encourage (protein, fiber, vitamins A, C and E, calcium, magnesium, iron, potassium) and three nutrients to limit (saturated fat, added sugars, sodium) per 100 calories.
Nutrient Rich Foods Approach – The NRF approach is a positive, total diet approach that considers the complete nutrient package of foods and beverages as a way to help people build healthier diets, and encourages the selection of nutrient-rich foods first from the five basic food groups.
