BENEFITS OF DIETARY FIBER - MYTH OR MEDICINE

In recent years, many health claims have been made about dietary and s upplemental fiber. However, some reports (eg, those regarding oat bran ) have been controversial. A review of scientifically rigorous studies shows that fiber has some preventive or therapeutic benefits in irrit able bowel syndrome, diverticulosis, colorectal cancer. diabetes, and hypercholesterolemia. However, it appears to have no direct benefit in patients with inflammatory bowel disease, gallstones, or obesity. The United States has one of the lowest per capita intakes of fiber in th e world, Therefore, increasing daily fiber intake either through diet or with supplements is recommended for most Americans, Consumer intere st groups should lobby for more fiber-enriched foods. The challenge fo r education and healthcare professionals alike is to remold the nation 's interest in and understanding of dietary fiber.
