Bananas are rich in vitamin B6, which is necessary for the production of new cells and hence prevents aging. They are also a great source of Vitamin C, Potassium, Fiber,and Manganese. These are just some of the nutrients that bananas provide. Bananas also have plenty of stomach-soothing fiber to keep your intestines healthy. The material that lines the inside surface of the large intestine may gradually become inflamed when you have too much sugar or fat intake in your diet. That inflammation may begin to cause symptoms such as abdominal cramping and diarrhea or constipation by interfering with bowel movements or channeling too much water into parts of the colon where it’s not needed.
