The Daily Values (DVs) on the Nutrition Facts Panel are based on 1968 RDAs. There is debate about which reference values should be used to update label DVs: population‐weighted (w) or highest (h) values of the current EARs or RDAs. Using NHANES 2007–8 data, we estimated current intake of 15 vitamins and minerals (V/M) and modeled intake in each of 4 hypothetical DV scenarios (wEAR, hEAR, wRDA, hRDA) for nutrients from fortified foods. In each scenario, levels of fortified V/M were adjusted to maintain the current % DV in fortified foods, keeping levels of other nutrients constant. Usual nutrient intakes and % with usual intakes < EAR were estimated with C‐SIDE for the population 4+ y (n= 7976) and subpopulations. Nutrient intakes and adequacy of intake changed minimally overall. The % of the population 4+ y with usual intakes < EAR in the current, wEAR and hRDA DV scenarios were 48, 49 and 46% for calcium; 96, 96 and 94% for vitamin D; and 44, 54 and 49% for vitamin A. Compared with the current scenario, potential increases in % < EAR were observed in the wEAR scenario for iron and folate among females, and for vitamin B6 and zinc among females and older adults. Declines in the % with vitamin C intakes < EAR were observed in the hRDA DV scenario. Results of this modeling exercise will help to inform decisions in revising the DVs for the Nutrition Facts Panel.
