NOTES: Sodium intake from food is reported as a 1-day mean rather than usual intake to be consistent with reporting method for other dietary sources; d = day; mg = milligram; SE = standard error.

aIncludes salt added in cooking and food preparation.

bSalt added by the consumer at the table.

cExcludes pregnant and lactating women; data for these persons are shown in Appendix F, Table F-1.

SOURCE: NHANES 2003–2006.

medicines (Szarfman et al., 1995; Ubeda et al., 2009), on a population level, medications overall contribute small amounts of sodium.

The mean 1-day intake from all sources combined for persons 2 or more years of age during the 2003–2006 period is 3,614 mg/d, as shown in Table 5-1. The Dietary Guidelines for Americans recommends < 2,300 mg/d for this age group. Although recent data from 2009 are not available, indirect measures of estimating sodium intake (including trends in caloric intake, rates of obesity, observational studies, and the lack of consumer education) provide no indication that there is a decline in sodium intake since the 2003–2006 NHANES.

Usual mean total sodium intake from all dietary sources (foods, table salt, tap water, dietary supplements9) increases with age from 2–3 years

Information on all prescription medicines and some over-the-counter medicines was collected in NHANES 2003–2006; however, no summary data on their sodium content were readily available for the committee’s analysis.
