Black Raspberries contain an extremely dark pigment which allows them to be used as a colorant and gives black raspberries one of the highest antioxidant ratings in common fruits and berries. Rich in ellagic acid, anthocyanins and antioxidants, black raspberries have been called the “king of berries” for their superior health benefits.
Studies at Ohio State University have found significant decreases in colon tumors in rats and esophageal tumors in mice fed a diet with black raspberries. In vitro studies have shown that extracts of raspberries and blackberries may slow the growth of breast cervical, colon and esophageal cancers. Human clinical trials are underway to assess the effects of black raspberries on colon and esophageal cancers in humans.
