USDA Develops a Database for Flavonoids to Assess Dietary Intakes

Seema Bhagwat, David B. Haytowitz, S. Wasswa-Kintu, Joanne M. Holden

Abstract

The Nutrient Data Laboratory (NDL) of ARS/USDA issued “USDA Database for the Flavonoid Content of Selected Foods, Release 3.1” in 2012. A complementary database for the “USDA Database for the Isoflavone Content of Selected Foods, Release 2” was issued in 2008. To support the assessment of the flavonoids intake these two databases were expanded to comprise approximately 2900 foods from USDA's National Nutrient Database for Standard Reference (SR). Various estimation techniques, long established for calculating unavailable values in SR, were used to complete this expanded flavonoids database for a total of 30 compounds for each of 2900 foods.
