Why does brown rice have more fiber then white rice?

Brown rice is an example of a whole grain - it is less processed, or milled, than white rice.

In the process of milling, white rice's husk, bran, and germ are removed. On the other hand, brown rice retains its bran and germ, which gives it the somewhat darker color.

Bran is the part of rice that provides significant quantities of dietary fiber, while germ is high in vitamins and minerals. White rice becomes artificially stripped of its fiber and many nutrients, while brown rice retains them. Consequently, brown rice offers more dietary fiber and other nutritional value to its consumers than white rice does.
