Values are means ± SEs (n) unless otherwise indicated. Values for phosphorus intake are estimated directly from day 1 dietary intake data and do not reflect the usual mean intake estimates approach used to estimate the distribution statistics. Data are from What We Eat in America, NHANES 2011–2012, nutrient intakes from food (data available from www.ars.usda.gov/nea/bhnrc/fsrg). EAR, Estimated Average Requirement; UL, Tolerable Upper Intake Level.
