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.
