Nutrition Chapter 2

Daily Value (DV)

Generic nutrient standard used on Nutrition Facts label; it comprises both Reference Daily Intakes (RDIs) and Daily Reference Values (DRVs)

Tolerable Upper Intake Level (UL)

Maximum chronic daily intake level of a nutrient that is unlikely to cause adverse health effects in almost all people in a specific life stage

Adequate Intake (AI)

Nutrient intake amount set for any nutrient for which insufficient research is available to establish an RDA. AIs are based on estimates of intakes that appear to maintain a defined nutritional state in a specific life stage

Recommended Dietary Allowance (RDA)

Nutrient intake amount sufficient to meet the needs of 97-98% of the individuals in a specific life stage

Estimated Average Requirements (EARs)

Nutrient intake amounts estimated to meet the needs of 50% of the individuals in a specific life stage

Acceptable Macronutrient Distribution Range (AMDR)

Range of macronutrient intake, as percent of energy, associated with reduced risk for chronic diseases while providing for recommended intake of essential nutrients

Estimated Energy Requirement (EER)

estimate of the energy (kcal) intake needed to match the energy use of an average person in a specific life stage

Daily Reference Values (DRVs)

part of the DV; generic nutrient standard set for energy-producing nutrients (fat, carbohydrate, protein, fiber), cholesterol, sodium, and potassium.

Reference Daily Intakes (RDIs)

part of the DV; generic nutrient standard set for vitamins minerals (except sodium and potassium)

Dietary Reference Intakes (DRIs)

term used to encompass nutrient recommendations made by the Food and Nutrition Board of the National Academy of Sciences. These include RDAs, EARs, Als, EERs, and ULs.
