1 Estimated average requirement (EAR) shown for lactating and non-lactating women 19 to 50 years, EAR for 14 to 18 years accounted for in calculations when appropriate. 2 Established by EAR cut-point method [43] with adjusted data. 3 Proportion z-score test between adjusted rates of inadequacy. 4 As retinol activity equivalents (RAEs); 1 RAE = 1 μg retinol, 12 μg β-carotene, 24 μg α-carotene, or 24 μg β-cryptoxanthin. 5 As estimated niacin equivalents (NE); 60 mg of tryptophan = 1 mg of niacin, tryptophan estimated to be 1% of protein [44]. 6 NS: non-significant. 7 As dietary folate equivalents (DFE); 1 DFE = 1 μg food folate = 0.6 μg of folic acid from fortified food. 8 Prevalence of inadequate intake determined by Institute of Medicine (IOM) probability equations assuming 18% bioavailability [29].
