Celery contains vitamin C, beta carotene, and flavonoids, but there are at least 12 additional kinds of antioxidant nutrients found in a single stalk. It’s also a wonderful source of phytonutrients, which have been shown to reduce instances of inflammation in the digestive tract, cells, blood vessels, and organs.
There’s a high water content of celery — almost 95 percent — plus generous amounts of soluble and insoluble fiber. All of those support a healthy digestive tract and keep you regular. One cup of celery sticks has 5 grams of dietary fiber.
