Prune is the dried fruit of certain European plum varieties. Its concentrated fiber and sorbitol content sets it apart from fresh plums and makes it a go to choice for encouraging regular bowel movements. A few prunes or a glass of prune juice offers a mild, food-based way to relieve occasional constipation.
The fruit also supplies vitamin K and boron, nutrients that help maintain bone density. Watch the serving size because prunes pack a lot of natural sugar and can bring on bloating or loose stools when overdone.
