Fiber is an important food group that is responsible for assisting in digestion.

It may also -arguably - be one of the most forgotten food types.

When you think of losing weight, you would think of cutting down on carbohydrates and when you want to build muscle, you would immediately go for protein foods - rarely fiber.

No worries though, if you aren't aware of which types of foods to get fiber from you can start with the five listed below.

1. Avocado

Avocado is a source of healthy fats and fiber.

2.Sweet potatoes

Sweet potatoes contain vitamin A, vitamin C and potassium which are great for the body's muscles and nerves.

They are also rich in fiber.

3. Lentils

They are rich in fiber and protein. The best part about them is that they are easy to prepare.

4.Oatmeal

Oatmeal is a muscle building food but it also contains a super fiber known as beta-glucan which gives it its cholesterol lowering effect.

Beta-glucan also helps to slow down digestion of your food thus making you feel full for longer.

5.Chia seeds

Add chia seeds in a smoothie, oatmeal or even yoghurt to help give you the necessary fiber you need.
