list of polyphenol foods
Choose richly hued fruits, vegetables, and whole grains. Rich colors such as reds and purples or black indicate that plant foods are excellent sources of polyphenols. Choose foods such as blueberries, pomegranates, red grapes, cranberries, and red or purple sweet potatoes. Blueberries as well as foods such as black rice, purple barley, black sorghum, and purple potatoes are sources of anthocyanins, as well as other polyphenols.
