Deskripsi

In the United States (U.S.), food fortification and/or enrichment and dietary supplement (DS) use impacts nutrient intakes. Our aim was to examine race/ethnicity and income (Poverty Income Ratio, PIR) differences in meeting the Dietary Reference Intakes based on estimated dietary intakes among the U.S. population age &#8805;2 years (<i>n</i> = 16,975). Two 24-hour recalls from the National Health and Nutrition Examination Survey (NHANES) cycles 2009&#8722;2012 were used to estimate the intake of 15 nutrients as naturally occurring, enriched/fortified, and plus DSs. Across racial/ethnic groups and within PIR categories, significant differences were observed in the %&lt; Estimated Average Requirement (EAR) for vitamin A following enrichment/fortification (E/F) and for vitamin B<sub>12</sub> and riboflavin following both E/F and DS use when comparing non-Hispanic blacks, Hispanics, and the other race/ethnicity group to non-Hispanic whites. The %&lt;EAR for iron and calcium also differed depending on race/ethnicity within PIR category (<i>p</i> &lt; 0.05). The %&lt;EAR was significantly lower for vitamin D after E/F for Hispanics, and after E/F combined with DS use for vitamins C and B<sub>6</sub> for Hispanics and the other race/ethnicity group than non-Hispanic whites. Non-Hispanic blacks were inadequate in all nutrients examined except vitamin C based on the %&lt;EAR than individuals of other races/ethnicities. Differences in the tolerable upper intake level (UL) of nutrients, especially folate and zinc, also varied by race/ethnicity and PIR category.
