Rich in fiber, red plums are a curious blend of sweet, sour and juicy.

While red plums only contain small amounts of vitamins and minerals -- less than 10 percent per serving of single plum -- they are still rich in a range of nutrients. With more than 100 milligrams of potassium per plum and trace amounts of zinc, red plums provide you with two essential minerals. Potassium helps regulate your heart’s electrical activity and maintain the acid-base balance. Zinc helps your body’s immune system, and you need it to be able to smell and taste. Red plums are also rich in vitamin A and members of the B-vitamin complex. Vitamin A keeps your eyes healthy, while the B vitamins help your body break down carbohydrates into usable energy. B vitamins also aid in the formation of red blood cells.
