Blueberries may have competition for antioxidant power. Scientists at Louisiana State University in Baton Rouge have found that black rice is also rich in anthocyanins.

Black rice was referred to as Forbidden Rice in ancient China because its consumption was reserved for the emperor and his court. These days, black rice is not so exclusive and may be more economical than fresh blueberries.
