Natural stool softener

Insoluble fiber is the most beneficial for softening stools.

 It does not dissolve in water and helps food pass more quickly from the stomach to the intestines.

 Wholewheat flour, nuts, beans, and vegetables, such as cauliflower, green beans, and potatoes all contain insoluble fiber.
