One simple sweet potato could help support the protective barrier lining your intestines. Eating one sweet potato with its skin about three times a week provides fiber, beta-carotene, antioxidants, and other plant compounds that can nourish the gut environment and support the intestinal lining. These nutrients may help maintain the mucus and cellular barrier that protects the digestive tract, especially when chronic stress places extra strain on the gut. A humble sweet potato may be doing more for your gut barrier than most people realize.
