Oat bran is rich in sugars and proteins.

Its main benefit is that it contains high levels of soluble fiber, which absorbs water in the intestine and expands to sizes up to 20 times its original volume without water. This results in a feeling of fullness while alleviating constipation.

Additionally, when oat bran enters the body, it attracts fat molecules, sugars, and toxins and eliminates them before they can be absorbed.
