Read on to find out more about the best substitutes for oat fiber.

What is Oat Fiber?

what is oat fiber

Oat fiber refers to the hull or outer shell of the oat grain and is a kind of pure insoluble fiber.

Your body cannot digest this kind of fiber and it passes through your stomach undigested.

Remember, oats are whole grain but the fiber isn’t.

This is because it is derived from the fibrous hull which makes it a byproduct of the separation of oat groats from the hull.

Whole oat groats are harvested from oats after washing and removing the hulls.

But unlike steel-cut oats, rolled oats, and other variants, oat fiber is made entirely from the husk.

Hence, it comprises purely insoluble fiber.

Coconut flour has more or less a similar composition to oat fiber. This makes the substitution a lot easier.

4 – Chia Seeds
