Dietary Reference Intakes (DRI)
a set of four lists of values for measuring the nutrient intakes of healthy people in the United States and Canada. The four lists are Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), and Tolerable Upper Levels (UL)
Daily Values
nutrient standards that are printed on food labels. Based on nutrient and energy recommendations for a general 2,000 calorie diet, they allow consumers to compare the nutrient and energy contents of packaged foods
Balance study
laboratory study in which a person is fed a controlled diet and the intake and excretion of a nutrient are measured. Balance studies are valid only for nutrients like calcium (chemical elements) that do not change while they are in the body
the amount of a nutrient that will just prevent the development of specific deficiency signs; distinguished from the DRI recommended intake value, which is a generous allowance with a margin of safety
Estimated Energy Requirement (EER)
the average dietary energy intake predicted to maintain energy balance in a healthy adult of a certain age, gender, weight, height, and level of physical activity consistent with good health
Food group plan
a diet-planning tool that sorts foods into groups based on their nutrient content and then specifies that people should eat certain minimum numbers of servings of foods from each group
Exchage System
a diet-planning tool that organizes foods with respect to their nutrient contents and calorie amounts. Foods on any single exchange list can be used interchageably
Discretionary Calorie allowance
the balance of calories remaining in a person's energy allowance after accounting for the number of calories needed to meet recommended nutrient intakes through consumption of nutrientdense foods
Healthy Eating Index (HEI)
a dietary assessment tool that evaluates a diet's adherence to the principles of the USDA Food Guide and the Dietary Guidelines for Americans, as well as the variety of foods that diet contains.
