what foods contain the most polyphenols
A study published in the March 2008 issue of The Journal of Nutrition found that dark grapes, bilberries, cherries, apples, dark plums, blackberries and blueberries were all good sources as well. Fruit juices, such as grape juice, contain especially high levels of polyphenols.
Red wine, chocolate, black tea, white tea, green tea, olive oil, argan oil, bee pollen and many grains are sources. Ingestion of polyphenols occurs by consuming a wide array of plant foods.
