Whether you juice or make smoothies, you will still get some fiber. There are the two kinds of fiber—here’s how they work in your body:
Soluble fiber remains in your juice even when you take out the pulp. Soluble fiber absorbs water in the intestines, forming a gel that helps slow the transit of food through your digestive tract. It also acts as a pre-biotic to support healthy bacteria in the gut.
Insoluble fiber remains in your smoothie as the pulp. Insoluble fiber makes you feel full because it literally takes up more room in your stomach. This fiber helps keep you regular. Since your body doesn’t absorb much of it, it also adds bulk to your stool.
