Pitted Prunes

Prunes are high in dietary fiber, with just one prune providing 3 percent of the recommended daily intake of fiber. Prunes are a good source of both insoluble and soluble fiber.

Insoluble fiber helps keep your bowel movements regular, while soluble fiber helps to moderate digestion and absorb nutrients from your food. Dried plums also contain sorbitol and chlorogenic acid, which can increase stool frequency.
