Flavonoids, polyphenolic compounds found in plants, exhibit anti‐inflammatory, anti‐tumor, and antioxidant activity. This study’s objective was to calculate national intake estimates for 6 flavonoid classes (including only the 29 predominant dietary flavonoids). One day of dietary data from 5,420 adults age 蠅20 years in What We Eat in America (WWEIA), NHANES 2007‐2008 was analyzed. Based on a preliminary version of USDA’s Expanded Flavonoid Database for the Assessment of Dietary Intakes, flavonoid values were calculated for every food in USDA’s Food and Nutrient Database for Dietary Studies 4.1, the database used in WWEIA 2007‐2008. Mean total intake of the flavonoids studied was 253.3 mg/day, with flavan‐3‐ols accounting for 81% of the total. Though total flavonoid intake did not differ by gender, men’s intakes of flavones (0.9 mg) and flavonols (21.5 mg) were higher than women’s (0.8 mg and 17.5 mg, respectively; p<0.01). No significant differences were found by age group (20‐49 vs. 50+ years) within gender. Nearly all (99%) adults consumed some flavonoids on the intake day, but intake of the flavonoid classes was not universal: Only 38% of adults consumed isoflavones; 64%, flavanones; and 69%, anthocyanidins. New public‐use databases will enable researchers to quantify flavonoid intakes of the U.S. population and allow further investigation of associations between flavonoid intake and health.
