we have been eating a lot of blueberries and i was wondering what are the benefits... it turns out that the dye released from the blueberries' skin is its most valuable nutrient! The pigments in blueberries as well as in other red crops like as cherries, plums, and red cabbage -!!yumms!!- are powerful antioxidants. Blueberries have the highest antioxidant capacity because of their large anthocyanin concentration. Anthocyanin fights against liver injuries, it reduces blood pressure, improves eyesight and has strong anti-inflammatory and antimicrobial powers. most importantly it fights the proliferation of human cancer cells.
