Purple Produce May Help Fight Diabetes, Study Finds.
Recent research has found that anthocyanins, the red, purple, and blue pigments found in fruits, vegetables, and tubers, can lower the risk of developing type 2 diabetes. The beneficial effect of anthocyanins on diabetes is amplified when they are acylated, meaning that an acyl group is attached to the sugar moieties of the anthocyanin. Purple vegetables such as potatoes, sweet potatoes, radishes, carrots, and red cabbages contain a great amount of acylated anthocyanins. Acylated anthocyanins have probiotic properties and reduce the risk of diabetes more efficiently than nonacylated anthocyanins.
