a Because there is less information on which to base allowances, these figures are not given in the main table of RDA and are provided here in the form of ranges of recommended intakes.

b Since the toxic levels for many trace elements may be only several times usual intakes, the upper levels for the trace elements given in this table should not be habitually exceeded.

Diets should be 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. b Weights and heights of Reference Adults are actual medians for the U.S. population of the designated age, as reported by NHANES II. The median weights and heights of those under 19 years of age were taken from Hamill et al. (1979) (see pages 16-17). The use of these figures does not imply that the height-to-weight ratios are ideal. c Retinol equivalents. 1 retinol equivalent = 1 mg retinol or 6 mg b-carotene. See text for calculation of vitamin A activity of diets as retinol equivalents. d As cholecalciferol. 10 mg cholecalciferol -- 400 IU of vitamin D. e a-Tocopherol equivalents. 1 mg d-a tocopherol = 1 a-TE. See text for variation in allowances and calculation of vitamin E activity of the diet as a-tocopherol equivalents. f 1 NE (niacin equivalent) is equal to I mg of niacin or 60 mg of dietary tryptophan.
