Yes. Black plum skins contain anthocyanins, an essential antioxidant, anti-inflammatory agent linked to the prevention of diabetes and other diseases.”
Unlike most fruits with edible flesh, black plums are rich in fiber and low in calories which makes them perfect for people who are on restrictive diets or want to lose weight. They can even be used as part of a diabetic diet without effecting blood sugar levels (unlike eating sweets) since they do not raise insulin levels like high glycemic foods do. The natural fibers found in black plums along with their low sugar content promote healthy digestive functions by promoting heartburn relief.
