Fiber#2
 

Most people who are living in economically rich countries, and even many bodybuilders, don’t get enough fiber as well as water, which cleanses the kidneys and the urinary track, fiber cleanses the digestive system, keeps things moving smoothly, and eliminates excess fluids.

The richest sources of fiber are fruits, vegetables, nuts, seeds, buckwheat, and oats. Alas, animal-based products provide too little fiber to stay healthy.
