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.

When the density is defined in proportion to energy contents, nutrient-dense foods such as meats, fruits and vegetables are the opposite of energy-dense food (also called "empty calorie" food), such as alcohol and foods high in added sugar or processed cereals.
Developed by Adam Drewnowski of the University of Washington, the Naturally Nutrient Rich system is based on mean-percentage Daily Values for 14 nutrients in food with 2,000 calories. It proposes to assign nutrient-density values to foods within and across food groups. The score allows consumers to identify and select nutrient-dense foods ...
According to the NHS, the recommended daily calorie intake is 2,000 calories a day for women and 2,500 for men. However, if you are more or less active you may choose to alter this slightly.
[1] [3] The small calorie or gram calorie is defined as the amount of heat needed to cause the same increase in one milliliter of water. [ 3 ] [ 4 ] [ 5 ] [ 1 ] Thus, 1 large calorie is equal to 1,000 small calories.
