NOTE: This table does not include nutrients for which Dietary Reference Intakes have recently been established (see Dietary Reference Intakes for Calcium, Phosphorus, Magnesium, Vitamin D, and Fluoride [1997] and Dietary Reference Intakes for Thiamin, Riboflavin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid, Biotin, and Choline [1998]).

a The 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 be based on a variety of common foods in order to provide other nutrients for which human requirements have been less well defined.

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). The use of these figures does not imply that the height-to-weight ratios are ideal.

c Retinol equivalents. 1 retinol equivalent = 1 µg retinol or 6 µg b-carotene.

d a-Tocopherol equivalents. 1 mg d-a tocopherol = 1 a-TE.
