DRIs

nutrient recommendations

• addresses issues of safety, quality, and adequacy of the food supply

• establishes principles and guidelines for adequate dietary intake

• makes authoritative judgements on relationships among food intake, nutrition, and health

DRI

general term for a set of reference values used to plan and assess adequacy of nutrient intake of healthy people

Estimated Av. Requirements (EAR)

• nutrient amount that meets the requirements of 50% of the people within a group of the same life stage and sex

• midpoint in the range of different individual requirements

Recommended Dietary Allowance (RDA)

average daily dietary nutrient intake that is sufficient to meet the nutrient requirements of nearly all healthy individuals in a certain age and gender group

Adequate Intake (AI)

recommended average daily intake level based on observed or experimentally determined approximates or estimates of nutrient intake by a group of apparently healthy people that are assumed to be adequate

• used when RDA can’t be determined

Tolerable Upper Intake Level (UL)

Highest average daily nutrient intake level likely to pose no risk of adverse health effects to almost all individuals in the general population

standards for energy

Estimated Energy Requirement (EER) calculated using equations that consider age, weight, height, and physical activity level

standards for macronutrients

Acceptable Macronutrient Distribution Range (AMDR) is expressed as a percent of energy intake from 5 macronutrients

challenges

assess the intakes of a group, need to obtain the distribution of usual intakes
