dietary reference intake (DRI)
set of values reflecting the average daily amounts of nutrients considered adequate to meet the known nutrient needs of practically all healthy people in a particular life stage
RECOMMENDED DIETARY ALLOWANCES (RDA)
set of values that are used as guides for nutrient intakes when scientific evidence is inufficient to determine an RDA
ADEQUATE INTAKES (AI)
the average daily nutnent intake levels (estimated to meet the requirements of half of the healthy individuals in a given age and gender group used in nutrition research
EAR (ESTIMATED AVERAGE REQUIREMENT)
set of values reflecting the highest average daily nutrient intake levels that are likely to pose no risk of toxicity to almost all healthy individuals in a particular life stage and gender group.
TOLERABLE UPPER INTAKE LEVELS (UL)
