Usual daily phosphorus intake data from What We Eat in America, NHANES 2005–2006 (unpublished data from Alanna Moshfegh, U.S. Department of Agriculture) are expressed as means ± SEs. The dietary recommended intake levels for phosphorus were established by the Institute of Medicine, Food, and Nutrition Board in1997 (23). EAR, estimated average requirements; UL, tolerable upper intake levels.
