During 2005−2006, only 9.6% of all participants met the applicable 2005 recommended dietary limit for sodium (5.5% among the ≤1,500 mg/day group; 18.8% among the <2,300 mg/day group). U.S. adults consumed an average of 3,466 mg/day of sodium. Most of the daily sodium consumed came from grains (1,288 mg; 36.9%) and meats, poultry, fish, and mixtures (994 mg; 27.9%), followed by vegetables (431 mg; 12.4%). Average daily sodium and calories consumed was 3,691 mg and 2,272 kcal for the <2,300 mg/day group and 3,366 mg and 2,068 kcal for the ≤1,500 mg/day group. Although the ≤1,500 mg/day group consumed statistically significantly less sodium (p<0.001) and calories (p<0.001) than the <2,300 mg/day group, no difference was observed in overall sodium density or in eight of the nine main categories. Small but statistically significant differences in density were observed for two of the grain subcategories, one of the meats subcategories, and one of the vegetables subcategories. The ≤1,500 mg/day group consumed less sodium and calories from grains (1,205 mg versus 1,474 mg of sodium and 704 kcal versus 839 kcal) and sugars, sweets, and beverages (118 mg versus 138 mg of sodium and 286 kcal versus 361 kcal). However, that group consumed more sodium and calories from certain types of vegetables (109 mg versus 74 mg of sodium and 42 kcal versus 29 kcal).
