Health food bars are meant to supplement an otherwise healthy diet, whether it's as a snack, a meal replacement or to help you power through your workouts. Breakfast bars and cereal bars are commonly marketed as a fiber-rich snack. The problem is, not all fiber bars are created equal.

Fiber Benefits and What to Look For

Dietary fiber is found in foods like whole grains, beans, fruits and vegetables. It's beneficial for digestive health, and a high-fiber diet is linked to a lower risk of heart disease, according to the Harvard School of Public Health. Look for a balanced bar that's low in sugar and sodium. Some fiber bars contain supplemental forms of fiber such as psyllium. Choose a bar that contains a food source of fiber, recommends Consumer Reports. For example, bran is fiber-rich, and many high-fiber bars contain bran, according to an article in the July 2008 issue of Today's Dietitian.
