The Paleo Diet®

Fiber

Unlike fats, proteins, and carbohydrates—which our bodies break down and absorb—fiber is not digested by gastrointestinal enzymes. Also known as roughage, fiber is the sum of the constituents of plant foods that are not digested. It has two main components: soluble fiber, which dissolves in water, and insoluble fiber, which does not.
