The
word fiber (North American) can also be spelled fibre (British). Fiber is the
structural part of a plant that supports and holds it together. 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.
Fiber
is made up of non-starch polysaccharides, such as cellulose, dextrins, inulin,
lignin, chitins, pectins, beta-glucans, waxes and oligosaccharides. The word
fiber is misleading, because many types of dietary fibers are not fibers at
all.
