Since 2005, NCC has maintained the NCC Flavonoid and Proanthocyanidin Provisional table. In the 2023 version of this table, values for one or more of 26 flavonoids* are provided for 1010 foods in the NCC Food and Nutrient Database. Additionally, values are provided for one or more of five classes of proanthocyanidins* for 1180 foods. Nutrient values in the provisional table are reported as mg/100g edible portion of food.
 
Nutrient values for the table have been compiled from the USDA Database for the Flavonoid Content of Selected Foods, Release 3.3 (Mar. 2018), the USDA Database for the Proanthocyanidin Content of Selected Foods, Release 2.1 (Mar. 2018), as well as from scientific literature.

The NCC Flavonoid and Proanthocyanidin Provision Table may be linked to foods in the NDSR component/ingredient output file. By carrying out this linkage, one may estimate intake of the flavonoids and proanthocyanidins in the Table, recognizing that composition data is missing for many foods, and therefore intake may be underestimated to some extent.
 
The current price for the 2023 Flavonoid and Proanthocyanadin Provisional table is $1,100. Please contact NCC for more information or if you are interested in licensing the table.
 
*Values are missing for some of the flavonoids/proanthocyanidins in the provisional table. Many of these values are based on analytical data and NCC imputed values for only some categories of food, for example cooked and corresponding canned vegetables were assigned similar values.
