Fiber is also known as roughage. It is the indigestible part of plant foods that pushes through our digestive system, absorbing water along the way and easing bowel movements.
- The word fiber (North American) can also be spelled fibre (British). It comes from the Latin word fibra, meaning fiber, thread, string, filament, entrails. Dietary fiber refers to nutrients in the diet that are not digested by gastrointestinal enzymes.http://www.fiberguardian.com/how-much-fiber-per-day/
