Raspberries contain high levels of ellagic acid, a polyphenol and antioxidant being studied as a food in the fight against cancer. Raspberries are also rich in anthocyanins, a flavonoid compound that gives them their red color. Anthocyanins may help protect the circulatory, cardiovascular and neurological systems. Raspberries are a rich source of vitamin C, manganese, and dietary fiber; and are a low-glycemic index food.
