¹With the exception of calcium and vitamin D, values are as reported by the FDA (2); the FDA’s reported population-weighted data are based on 2005 U.S. population projections (10). Values for calcium and vitamin D are based on current DRIs (5); population-weighted calcium and vitamin D values were derived by using 2005 population projection data to be consistent with FDA reported values for other nutrients (10). AT, α-tocopherol; DV, Daily Value; EAR, Estimated Average Requirement; RAE, retinol activity equivalent; RE, retinol equivalent.
