Questions and Answers
What can be inferred about an individual's nutrient intake if it consistently exceeds the RDA?
The intake is likely adequate, as the RDA meets the needs of almost all people.
How should an intake that falls between the RDA and the EAR be viewed in terms of adequacy?
It may be adequate, but there is a significant possibility that it is inadequate.
What does an intake below the EAR typically indicate about a person's nutrient consumption?
It is probably inadequate.
What are Tolerable Upper Intake Levels (UL) and why are they important?

Study Notes
Recommended Dietary Allowance (RDA)
- The RDA meets the needs of almost all people.
- If a person’s usual intake is above the RDA, then the intake is likely adequate.
Estimated Average Requirement (EAR)
- The EAR meets the needs of 50% of the population.
- If a person’s usual intake falls between the RDA and the EAR, it may be adequate, but it’s more likely to be inadequate.
- If the usual intake falls below the EAR, then the intake is likely inadequate.
Tolerable Upper Intake Level (UL)
- UL is the highest average daily nutrient intake that is unlikely to pose a toxicity risk to individuals.
- ULs are established for nutrients that can be hazardous when consumed in excessive amounts.
