Within the Nutrition, Bone and Oral Health Research Group, her team’s overall research goal is to develop dietary strategies that help protect against osteoporosis, and to also understand how diet can be used to promote periodontal health. Using advanced imaging, biomechanical strength testing and biochemical analyses the team investigates how calcium and vitamin D, as well as novel foods and food components including flaxseed and its omega-3 fatty acid, fish oil, flavonoids in tea and citrus, and soy and its isoflavones impact bone health using preclinical models. Sex-specific responses are studied within these studies. These projects are funded by major government granting agencies (NSERC, CIHR, CFI). Clinical studies investigate how diet is associated with better periodontal health and healing outcomes after periodontal procedures.
Current research interests involve humans or experimental models to investigate the following areas:
- The mechanisms by which foods or bioactives – including flavonoids present in tea or dietary estrogens such as flaxseed lignans or soy isoflavones, or specific fatty acids – modulate bone metabolism during aging
- How foods or food components promote oral health and healing after periodontal procedures
- Nutritional Programming: Understanding how early diet – including soy isoflavones, folic acid, vitamin D and protein – favourably programs bone and muscle metabolism
- Gut-Bone Axis: How the gut associated microbial community or the molecules they synthesize modulate bone health (in collaboration with E. Comelli, University of Toronto)
- I am actively involved in knowledge translation activities for health professionals and lay audiences on topics related to nutrition and issues relating to oral health and/or women’s health
- Editor in Chief, Applied Physiology, Nutrition and Metabolism (journal of the Canadian Nutrition Society and Canadian Society for Exercise Physiology)
- Chair, Diet Working Group, for the Clinical Practice Guidelines for the Diagnosis and Management of Osteoporosis in Canada
- Chair, Research Committee and Member, Scientific Advisory Council, Osteoporosis Canada
- Member, Education Committee, Canadian Nutrition Society
Dr. Ward’s team has published many peer-reviewed articles, invited reviews and book chapters on the topic of nutrition and health, with particular emphasis on the use of nutritional interventions to support both bone and periodontal health.
Trainees at all levels are actively involved in the research program and are integral to its success (denoted by *).
