Toxins tend to accumulate in the digestive tract. It can be from the food preservatives you consume or the body waste yet to be disposed. If these are not released properly, you can suffer from bloating, tiredness, and other illnesses.
Introducing fiber to your diet will help your digestive tract work properly and flush the toxins and excessive wastes out of your body.
Instead of taking fiber supplements, make sure that you take fiber as naturally as possible. Fresh vegetables and fruits, whole grains, legumes, and beans are great sources of fiber.
