Eat Your Fiber
A human study of dietary fiber was completed in December 2007 for an Iowa company. Over three 14 day periods, subjects in random order ate a high fiber breakfast bar containing wheat bran or the test fiber, or a control low fiber bar. Dr. Suzanne Hendrich and researchers found the fecal weight change per gram of dietary fiber added was similar between the test fiber and wheat bran.
Dietary fiber intakes were significantly increased by the addition of high fiber breakfast bars to daily diets, with no adverse effects on gastrointestinal function. There was little effect of the fiber source on blood glucose, but they may exert other diabetes preventive effects. The new dietary fiber, functioning similar to wheat bran, may open new product markets given the increasing public awareness of the need to eat more dietary fiber, and the need to make new, tasty food products containing more fiber.
