Before we get to the best food sources of fiber, let’s understand one simple thing…

What Is Fiber? Why Do You Need It?

Fiber is a class of non-digestible, complex carbohydrates. It can be found in plants or is added to foods. The primary role of different classes of fiber is to act as prebiotics (1).

As prebiotics, they promote the activity of the good bacteria in the gut (gut microbiota). Another crucial role of fiber is to maintain blood cholesterol levels. This activity is particularly attributed to soluble fiber. Soluble fiber is commonly found in fruits, legumes, and oats (1).

The other class of fiber, insoluble fiber, is associated with the prevention of constipation and appetite control. Insoluble fiber is found in wheat, bran, and vegetables (1).

In this article, we have presented a list of high-fiber foods. We have categorized them into five major groups. You must have eaten a few or maybe all of them without knowing the amount of fiber they contain.
