a EAR = Estimated Average Requirement; RDA = Recommended Dietary Allowance; AI = Adequate Intake.

b NA = not applicable.

c The EAR and RDA for folate are expressed as μg dietary folate equivalents (DFE). However, insufficient information was available to convert intake data from the Continuing Survey of Food Intakes by Individuals to DFEs, thus for this example, folate intake is expressed in micrograms.

d Mean and median intake expressed as mg of α-tocopherol.

e Dietary intake data for selenium and vitamin E are from the Third National Health and Nutrition Examination Survey, 1988–1994.

SOURCE: 1994-1996 Continuing Survey of Food Intakes by Individuals.

* NOTE: Does not include intake from supplements.

APPLICATION 2: ASSESSING THE PREVALENCE OF INADEQUATE OR EXCESSIVE INTAKE

What proportion of the population has inadequate nutrient intake? What proportion of the population is at risk of excessive nutrient intake?

Data available: 24-hour dietary recall data on a nationally representative sample of individuals, with two or more nonconsecutive days of data collected for at least a subsample of individuals.
