Plums originated in China. Their season is early spring until autumn with the peak harvest late in summer. One cup of fresh plums contains 76 calories, 1.2 grams of protein, 18.8 grams of carbohydrates and 2.3 grams of fiber. In 1/4 cup of prunes there are 104 calories, 1 gram of protein, 27.8 grams of carbohydrates and 3.1 grams of fiber. Plums are also popular in their dried form, known as a prune.
Plums are excellent sources of vitamins A, C, and K and fiber. They are also a good source of potassium and copper. They contain anthocyanins and the antioxidant carotenoids beta-carotene, lutein and zeaxanthin. Plums are best used fresh to retain vitamin C and they make a nutritious addition to salads. Prunes can be chopped and added to a variety of baked goods to boost nutrition value as well as rice dishes to add antioxidants and minerals.
