Fiber Up

Proteins, fats, carbohydrates, vitamins, and minerals are all basic materials from which our bodies build muscle, repair tissue, and draw energy. But fiber, that mysterious substance we hear about periodically, plays a vital role as well.

Not only does fiber bind fats in the intestine and help lower cholesterol levels; it takes direct aim at preventing cancer. The body’s inability to entirely digest fiber accounts for its role as a source of bulk, which helps the intestines move waste along, a weapon in the war against cancer-causing bacteria in the digestive tract.

Fiber also helps produce and repair colon cells.
