Document Summary
The basics of a healthful diet: variety, moderation, and proportionality. Variety in your diet means choosing foods from all the food groups and subgroups, rather than eating the same old thing day after day. Variety makes meals more interesting and helps ensure that a diet contains suf cient nutrients. A variety of foods is best because no one food meets all your nutrient needs. The ve major food groups: grains, vegetables, fruits, dairy, and protein. Balance also refers to matching your energy intake with energy expenditure (calories burned by metabolism and physical activity) over time. The nutrient density of a food is a characteristic used to determine its nutritional quality. Nutrient density of a food is determined by comparing its protein, vitamin, or mineral content with the amount of calories it provides. Food is deemed nutrient dense if it provides a large amount of a nutrient for a relatively small amount of calories when compared with other food sources.
