THE FIX: Many foods are boasting higher fiber content—even yogurt, which doesn’t naturally contain fiber. The reason: Food manufacturers are isolating specific types of fiber and adding them to breads and other packaged foods. Can this added fiber take the place of whole grains and provide the same health benefits as naturally occurring fiber? The verdict is still out. Studies have found that these added fibers perform some of the same functions as dietary fiber, such as aiding in digestion and increasing satiety. They are not, however, equal to the fiber found naturally in food. It’s difficult to compare a serving of nutrient-rich green beans to a packet of artificial sweetener with added fiber. For the most part, foods with added fiber (or any other synthetically-added nutrition enhancers, for that matter) don’t provide the vitamins, minerals, and other nutrients associated with naturally high-fiber foods.
