Exploring the Nutritional Value of Dietary Fiber
Sunday, July 12; 1:30–3 p.m.
Those who attend session 40 can expect to come away from the symposium with a renewed appreciation for the role that dietary fiber plays in human health and deeper insights into the way it affects body fat, satiety, and glycemic control. Symposium presenters point out that dietary fiber is a complex mixture of components that—unlike other nutrients—derives its nutritional value not from being digested and absorbed but by remaining undigested after passing through the stomach and small intestine. This session will provide an update on some of the latest research on the physiology of dietary fiber.
Julie Miller Jones will kick off the symposium with a presentation that will explore the importance of getting enough fiber and the correct balance of fiber types without consuming excess calories. Her presentation is highly relevant considering that only 4% of the U.S. population achieves adequate intake of fiber. Jones, a distinguished scholar and professor emerita of the College of St. Catherine in St. Paul, Minn., is a widely recognized authority on whole grains and dietary fiber.
The symposium’s next presenter, Jonathan DeVries, recently retired from General Mills, where he served as senior technical manager for the Medallion Laboratories division. His presentation will focus on current knowledge about the physiological effects of dietary fiber—an important topic given the complexity of establishing adequate dietary intakes of fiber in total and for particular components. DeVries will also serve as the session moderator.
Presenter Daniel Gallaher, a professor in the Dept. of Food Science and Nutrition at the University of Minnesota, will delve deeply into the subject matter, discussing the ways that the dietary fiber characteristics of viscosity and fermentability affect body fat and satiety-related hormones. The symposium’s final presenter is Cyril Kendall, a research associate in the Dept. of Nutritional Sciences, Faculty of Medicine, University of Toronto. He will consider the relevance of glycemic control to health and explore the dynamics of dietary fiber digestion.
