NOTE: This table (taken from the DRI reports, see www.nap.edu) presents Recommended Dietary Allowances (RDAs) in bold type and Adequate Intakes (AIs) in ordinary type followed by an
asterisk (*). RDAs and AIs may both be used as goals forindividual intake. RDAs are set to meet the needs of almost all (97 to 98 percent) individuals in a group. For healthy breastfed infants,
the AI is the mean intake. The AI for other life stage and gender groups is believed to cover needs of all individuals in the group, but lack of data or uncertainty in the data prevent being able to
specify with confidence the percentage of individuals covered by thisintake.
a
As retinol activity equivalents (RAEs). 1 RAE = 1 µg retinol, 12 µg β -carotene, 24 µg α-carotene, or 24 µg β -cryptoxanthin. The RAE for dietary provitamin A carotenoids is twofold greater
than retinol equivalents (RE), whereas the RAE for preformed vitamin A is the same as RE.
b
As cholecalciferol. 1 µg cholecalciferol = 40 IU vitamin D.
c
In the absence of adequate exposure tosunlight.
d
As α-tocopherol. α-Tocopherol includes RRR-α-tocopherol, the only form of α-tocopherol that occurs naturally in foods, and the 2R-stereoisomeric forms of α-tocopherol (RRR-, RSR-, RRS-,
and RSS-α-tocopherol) that occur in fortified foods and supplements. It does not include the 2S-stereoisomeric forms of α-tocopherol (SRR-, SSR-, SRS-, and SSS-α-tocopherol), also found in
fortifiedfoods and supplements.
e
As niacin equivalents (NE). 1 mg of niacin = 60 mg of tryptophan; 0–6 months = preformed niacin (not NE).
f
As dietary folate equivalents (DFE). 1 DFE = 1 µg food folate = 0.6 µg of folic acid from fortified food or as a supplement consumed with food = 0.5 µg of a supplement taken on an empty
stomach.
g
Although AIs have been set for choline, there are few data...
