Deep Colors Of The Food Rainbow: Anthocyanin Flavonoids

Taste the rainbow! Ever wonder where fruit and vegetables get their rich hues of purple, blue, and red? These pigments come from the flavonoids of anthocyanins.

The powerful flavonoids are found in blueberries, bilberries, purple cabbage, eggplant, cherries, blackberries, and black currants. The bright reds of strawberries, pomegranates, raspberries, cranberries, concord grapes and even red wine have significant amounts of these beneficial flavonoids.
