insoluble fiber
Undigested plant material
Insoluble fiber is dietary fiber that doesn't dissolve in water.
It passes through the digestive system largely intact, adding bulk to stool and promoting regular bowel movements.
Found in whole grains, nuts, and vegetable skins, it's distinguished from soluble fiber, which dissolves and forms a gel.
Wheat bran is high in insoluble fiber.
