Interpretive Summary: In the field of nutrition, there is much interest in studying relationships between health and dietary intake of flavonoids, a large class of naturally-occurring, plant-based, bioactive compounds. Until recently, U.S. databases of flavonoid content had not covered all foods and beverages, which limited the ability to examine relationships between flavonoid intake and health. That lack was alleviated by our 2014 release of the Provisional Flavonoid Addendum to the USDA Food and Nutrient Database for Dietary Studies, 4.1 – a comprehensive database of flavonoid values for 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 survey cycle. In 2014, we also released the Flavonoid Intake Data Files for WWEIA, NHANES 2007-2008. Now, using those flavonoid intake data files, we have developed 4 tables presenting, for the first time, 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 may be downloaded from the Web site of the USDA Food Surveys Research Group at www.ars.usda.gov/nea/bhnrc/fsrg, thus giving users immediate access to estimates of U.S. flavonoid intakes that are more comprehensive than any previously available. The flavonoid intake tables will be used by policymakers interested in setting national dietary guidance regarding flavonoids, as well as by nutritionists and others in need of current population-level information on flavonoid intakes by Americans overall and by specific sociodemographic groups.

Technical Abstract: The Food Surveys Research Group of the Beltsville Human Nutrition Research Center has released 4 flavonoid intake data tables that make available, for the first time, 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 survey cycle. Day 1 data from 8,529 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 214.45 mg; anthocyanidins, 9.36 mg; flavan-3-ols, 172.95 mg; flavanones, 12.97 mg; flavones, 0.76 mg; flavonols, 16.92 mg; and isoflavones, 1.50 mg. The tables may be downloaded from the Web site of the USDA Food Surveys Research Group at www.ars.usda.gov/nea/bhnrc/fsrg.
