Nutrient density identifies the amount of beneficial nutrients in a food product in proportion to e.g. energy content, weight or amount of perceived detrimental nutrients. Terms such as nutrient rich and micronutrient dense refer to similar properties.
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons.

Granulated sugar provides energy in the form of calories, but has no other nutritional value. In human nutrition, empty calories are those calories found in foods and beverages (including alcohol) [1] composed primarily or solely of calorie-rich macronutrients such as sugars and fats, but little or no micronutrients, fibre, or protein.
Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1] As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels.
Cassava root, for example, is a major food staple in the developing world, a basic food source for around 500 million people. With economic development and free trade, many countries have shifted away from low-nutrient-density staple foods to higher-nutrient-density staples, as well as towards greater meat consumption.
