headline bar

USDA has published several Special Interest Databases (SID) on flavonoids, which are presented below.  These databases were released separately as data became available.  It is anticipated that they will be combined into one database in the future.  You will need the Adobe Acrobat viewer to view the reports accompanying each SID. The databases are:


 

USDA Database for the Flavonoid Content of Selected Foods, Release 3.2 (November 2015)

The database contains values for 506 food items for five subclasses of flavonoids:


 

USDA Database for the Isoflavone Content of Selected Foods, Release 2.1 (November 2015)

This database contains data on the isoflavone content of 560 food items.  Isoflavones included in the database are daidzein, genistein, glycitein and total isoflavones.  Other phytoestrogens (coumestrol, biochanin A, and formononetin) are included as a separate table in the PDF report and in the database.   


 

USDA Database for the Proanthocyanidin Content of Selected Foods, Release 2 (2015)

The database contains values for 284 food items for the following proanthocyanidins groups:


 

USDA's Expanded Flavonoid Database for the Assessment of Dietary Intakes, Release 1.1 - December 2015

The database was developed with support from the Office of Dietary Supplements, National Institutes of Health for flavonoid intake studies.  The database is a useful tool  for flavonoid intake and health outcome studies for any population globally.  It contains data for 29 individual flavonoid compounds in six subclasses of flavonoids for every food in a subset of 2926 food items which provide the basis for the Food and Nutrient Database for Dietary Studies (FNDDS 4.1).  Proanthocyanidins data are not included at the present time.  For flavonoid intake data for the U.S. population based on NHANES 2007-08, please refer to the Food Surveys Research Group web site.
