nutrient density
A way of expressing the nutrient content of a food or diet relative to the energy yield (i.e. /1000 kcal or /MJ) rather than per unit weight.

nutrient density
The measurement of the amount of carbohydrates, fats, proteins, minerals, and vitamins per 100 kilocalories of a food. A distinction is usually made between energy nutrients (carbohydrates and fats) and the other essential nutrients. Therefore, nutrient density is sometimes expressed as amount of vitamins and minerals (and sometimes proteins) per unit of energy. Foods high in energy often contain a low density of most of the other essential nutrients (see junk food). Those who follow a low calorie diet should try to consume foods with a high nutrient density.

nutrient density
A measure of the amount of nutrients per unit energy of food. Nutrient density usually relates to the amount of vitamins and minerals (and sometimes proteins) per 100 g of the food or per 1000 kcal of that food.

Nutrient Density
Nutrient density is a measure of the nutrients a food provides compared to the calories it provides. Foods low in calories and high in nutrients are nutrient dense, while foods high in calories and low in nutrients are nutrient poor. Nutrient-dense foods should be eaten often, whereas nutrient-poor foods should only be eaten occasionally. A healthful diet includes mostly nutrient-dense foods. People who restrict their calories should obtain as much nutrition as they can from the calories they consume by choosing nutrient-dense foods. Those who consistently choose nutrient-poor foods will not get the nutrients they need.

Nutrient density
The term nutrient density has several meanings.
Most commonly, nutrient density is defined as a ratio of nutrient content (in grams) to the total energy content (in kilocalories or joules). Nutrient-dense food is opposite to energy-dense food (also called "empty calorie" food). According to the Dietary Guidelines for Americans 2005, nutrient-dense foods are those foods that provide substantial amounts of vitamins and minerals and relatively few calories. Fruits and vegetables are the nutrient-dense foods, while products containing added sugars, processed cereals, and alcohol are not.[1][2][3]
Second, nutrient density is defined as a ratio of food energy from carbohydrate, protein or fat to the total food energy. To calculate nutrient density (in percent), divide the food energy (in calories or joules) from one particular nutrient by the total food energy in the given food.
Third, nutrient density is understood as the ratio of the nutrient composition of a given food to the nutrient requirements of the human body. Therefore, a nutrient-dense food is the food that delivers a complete nutritional package.
