Preventing fragility fractures is an important goal for healthy, active aging among Canadians. While a healthful diet is one aspect that supports a strong skeleton during aging, individuals with metabolic syndrome may face specific challenges to bone health that may not always be readily recognized. For example, while bone mineral density may actually be higher and suggest better bone health, less commonly measured outcomes such as bone structure and strength can show the opposite relationship. Current data identify multiple modulators of bone health: heavier body weight, altered body composition, greater risk of falls and/or glucose intolerance. Each of these aspects may have a distinct effect on risk of fragility fracture. Collectively, these studies identify a complex relationship between metabolic syndrome and bone health. This talk will discuss how aspects of metabolic syndrome alter bone status, as well as the impact of lifestyle approaches, including dietary restriction and supplement use that may be combined with physical activity to support bone health.

Speaker:
Dr. Wendy Ward, PhD
Brock University

Dr. Ward obtained her Ph.D. in Medical Science from McMaster University, Canada, held a National Institute of Nutrition Postdoctoral Fellowship at the University of Toronto and was later an Assistant and Associate Professor in the Department of Nutritional Sciences, Faculty of Medicine, University of Toronto. During this time Wendy was an awardee of a Future Leader Award from the International Life Sciences Institute for her research on programming of bone metabolism by early diet. Wendy is currently a Professor and Canada Research Chair in Bone and Muscle Development in the Faculty of Applied Health Sciences at Brock University. Her research program, funded by CIHR, NSERC and CFI is focused on studying the mechanisms by which foods and food components regulate bone metabolism throughout the life cycle, with the long-term goal of developing dietary strategies that protect against fragility fracture and osteoporosis. Specific foods and food components of interest include vitamin D, tea and its flavonoids, soy and its isoflavones, flaxseed and its lignans, and omega-3 fatty acids. She has published many peer-reviewed articles and invited reviews in the area of nutrition and bone health, and book chapters on nutrition and womens health issues, particularly osteoporosis. She has co-edited two books: Optimizing Womens Health Through Nutrition and Food Drug Synergy and Safety, and has authored textbook chapters on the topics of micronutrients, herbal preparations and nutritional supplements. Wendy serves as an Associate Editor for the journal Applied Physiology, Nutrition and Metabolism and as a member of the editorial board for the Journal of Nutrition. She also serves as Chair, Research Committee of the Scientific Advisory Committee of Osteoporosis Canada. Wendy is actively involved in continuing education for health professionals on a variety of topics relating to nutrition and health-related topics.
