Interpretive Summary: The USDA Food Surveys Research Group of the Beltsville Human Nutrition Research Center has developed tables summarizing flavonoid intakes for the U.S. population age 2 years and over. Estimates presented are based on all foods and beverages reported in the What We Eat In America (WWEIA), National Health and Nutrition Examination Survey (NHANES) 2017-2018. The tables provide daily mean intakes per individual for 29 individual flavonoids in 6 flavonoid classes grouped by gender and age, race/ethnicity, and annual household income expressed both in dollars and as a percentage of the poverty threshold. Available for download on the Food Surveys Research Group website, these tables provide users immediate access to comprehensive information concerning U.S. flavonoid intakes. They 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 phytochemicals with documented biological activities that have the potential to promote health and prevent disease. Accordingly, there is much interest in quantifying intake of these compounds. Though population-based estimates reflecting dietary intake in 2007-2010 have been previously released, information about more current intakes is needed. By analyzing 1 day of 24-hour recall data from the What We Eat In America (WWEIA), National Health and Nutrition Examination (NHANES) 2017-2018, the Food Surveys Research Group of the Beltsville Human Nutrition Research Center has produced summary tables describing the flavonoid intake of the U.S. population during that survey cycle’s timeframe. These tables provide nationally representative estimates of the dietary intake of 29 individual flavonoids in six classes by individuals in the United States grouped by sociodemographic characteristics. 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 the poverty threshold. Among all individuals aged 2 years and over, mean estimated daily intake of total flavonoids was 184.77 mg; anthocyanidins, 14.06 mg; flavan-3-ols, 140.57 mg (catechins only, 65.90 mg); flavanones, 10.55 mg; flavones, 0.83 mg; flavonols, 16.32 mg; and isoflavones, 2.44 mg.
