"A good source of fiber." Sound familiar? You've likely seen this sentence on everything from boxed cereals to a container of yogurt. But do fiber-fortified foods (that is, foods that have synthetic fiber specifically added to them) really improve your health? It's a little unclear.

It is generally believed that people with high-fiber diets have lower rates of heart disease. But according to John Swartzberg, a professor of public health at University of California, Berkeley, no one really knows why fiber-rich foods appear to prevent heart disease.
