aThe allowances, expressed as average daily intakes over time, are intended to provide for individual variations among most normal persons as they live in the United States under usual environmental stresses. Diets should he based on a variety of common foods in order to provide other nutrients for which human requirements have been less well defined. See text for detailed discussion of allowances and of nutrients not tabulated.

bWeights and heights of Reference Adults are actual medians for the US population of the designated age, as reported by NHANES II. The use of these figures does not imply that the height-to-weight ratios are ideal.

cRetinol equivalents. 1 retinal equivalent = 1 mg retinol or 6 mg b-carotene.

dAs chalecalciferol. 10 mg cholecalciferol = 400 IU of vitamin D.

ea-Tocopherol equivalents. 1 mg d-a tocopheral = 1 a-TE.
f1 NE (niacin equivalent) is equal to 1 mg of niacin or 60 mg of dietary tryptophan.
