Roughage
Roughage
Roughage (/ˈrʌfɪdʒ/), also known as dietary fiber or bulk, is a type of carbohydrate that the body cannot digest. It is found in the plants we eat — fruits, vegetables, grains, and legumes.
Etymology
The term "roughage" comes from the Old English "rūh" meaning "rough" and the suffix "-age" which denotes action or a resulting state. It was first used in the late 19th century to describe food components that provide bulk but are not easily digested.
Definition
Roughage is the indigestible part of plant foods that pushes through our digestive system, absorbing water along the way and easing bowel movements. It is divided into two categories: soluble and insoluble fiber. Soluble fiber dissolves in water, forming a gel-like substance that can lower blood cholesterol and glucose levels. Insoluble fiber, on the other hand, promotes the movement of material through the digestive system and increases stool bulk.
