Celery

At just 10 calories a stalk, it’s claim to fame may be that it’s long been considered a low-calorie “diet food.”But this crispy, crunchy vegetable actually has a number of health benefits that may surprise you. It is a great source of antioxidants. There’s also the high water content of celery which is almost 95 percent plus generous amounts of soluble and insoluble fiber. All of those support a healthy digestive tract and keep you regular.
