Interpretive Summary: Using the newly released Flavonoid Intake Data Files for What We Eat in America (WWEIA), NHANES 2007-2010, the USDA Food Surveys Research Group (FSRG) has developed 4 tables presenting nationally representative estimates of flavonoid intakes for the U.S. population age 2 years and over. The tables provide estimates of daily mean intakes per individual for 29 individual flavonoids in 6 flavonoid classes (as well as the sum of those flavonoids) grouped by gender and age, race/ethnicity, and annual household income expressed both in dollars and as a percentage of poverty. These tables, available for download on the Food Surveys Research Group Web site, provide users immediate access to comprehensive estimates of U.S. flavonoid intakes. The flavonoid intake tables may be used by policymakers interested in setting national dietary guidance regarding flavonoids, as well as nutrition professionals, and others in need of current population-level information on flavonoid intakes by Americans overall and by specific sociodemographic groups.
Technical Abstract: Flavonoids are naturally-occurring, bioactive phytochemicals which may play important roles in promoting health and preventing disease. Consequently, there is much interest in quantifying dietary intake of these compounds. Until recently, population-based estimates have not been readily available. The Food Surveys Research Group of the Beltsville Human Nutrition Research Center has released flavonoid intake data tables that provide nationally representative estimates of the intake of 29 individual flavonoids in six classes (as well as the sum of those flavonoids) for individuals in the United States grouped by sociodemographic characteristics. Estimates of flavonoid intake are based on all foods and beverages reported in What We Eat in America (WWEIA), the dietary intake interview component of the National Health and Nutrition Examination Survey (NHANES), during the 2007-2008 and 2009-2010 survey cycles. Day 1 data from individuals age 2 years and over (excluding breastfed children) were used, and sample weights were applied to calculate estimates representative of the U.S. population. Estimated means and standard errors are provided by gender and age, race/ethnicity, and annual household income expressed both in dollars and as a percentage of poverty. Among all individuals age 2 years and over, mean daily intake of total flavonoids was 209.12 mg; anthocyanidins, 11.42 mg; flavan-3-ols, 164.91 mg (catechins only, 71.08 mg); flavanones, 13.25 mg; flavones, 0.81 mg; flavonols, 17.25 mg; and isoflavones, 1.48 mg.
