Recommended Dietary Allowances (RDA),
Adequate Intakes (AI), and Tolerable
Upper Intake Levels (UL).
EAR Estimated Average Requirements- Average
amount sufficient for half of population
RDA Recommended dietary allowance- the
amount of nutrients that will prevent
deficiencies
Adequate Intakes the average daily
AI amount of a nutrient that appears
sufficient to maintain a specified
criterion, a value used as a guide for
nutrient intake when RDA cannot be
determined.
Tolerable upper intake level. The maximum daily
UL amount of a nutrient that appears
safe for most healthy people and beyond

health effects.
Estimated Energy the average dietary energy intake that
