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. The databases are:
USDA Database for the Flavonoid Content of Selected Foods, Release 3.3 (March 2018)
The database contains values for 506 food items for five subclasses of flavonoids:
Flavonoid Content of Selected Foods Access Database_R 3.3 - This file contains the Flavonoid Database imported into a MS Access database. In addition to the summary values in the above table, a separate file containing the individual values used to calculate the summary values is included, along with all information on conversion factors used to calculate the individual aglycone values, analytical method, country of origin, etc. It also includes relationships between files. You need MS Access 2007 or later to use this file. The file structure is the same as that of the USDA National Nutrient Database for Standard Reference.
USDA Database for the Flavonoid Content of Selected Foods, Release 3.1 (December 2013)
The database contains values for 506 food items for five subclasses of flavonoids:
Flavonoid Content of Selected Foods Access Database R 3.1 - This file contains the Flavonoid Database imported into a MS Access database. It includes relationships between files. You need MS Access 2003 or later to use this file. The file structure is the same as that of the USDA National Nutrient Database for Standard Reference.
Note: The May 2014 update restored data for "Tea, green, brewed", (NDB No. 14653)
USDA's Expanded Flavonoid Database for the Assessment of Dietary Intakes, Release 1.1
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.
FDB-EXP_R01-1.accdb - This file contains USDA's Expanded Flavonoid Database for the Assessment of Dietary Intakesimported into a MS Access database. It includes relationships between files. You need MS Access 2007 or later to use this file. The file structure is the same as that of the USDA National Nutrient Database for Standard Reference. Release 1 of the database and documentation is available for users who need it for historical purposes.
