Beth MansfieldDr. Elizabeth (Beth) Mansfield, PhD, MSc, RD, is a Sport Nutrition Specialist, Registered Dietitian and Certified Exercise Physiologist with Peak Performance based in Ottawa. Beth works with Canada's national teams and athletes at the international, national, provincial, regional and professional levels to ensure that they are eating for peak health and performance. She also specializes in applying training principles developed for sport performance to business executives and workplace wellness programs in both governmental and NGO sectors.

Dr. Mansfield also works in the Bureau of Nutritional Sciences at Health Canada. Her social science research uses evidence based analysis in a systematic way to answer practical nutrition related concerns/questions such as, does vigorous exercise counteract less than optimal eating habits for weight control? Her current research, done in partnership with McGill University's School of Dietetics and Human Nutrition, investigates individual, social and environmental correlates of weight control in recreational women runners and is the first body of research to look at the eating habits of a representative sample of Canadian women involved in training and competing in road running races throughout Canada. Other research interests include the integration of a health literate approach to the labelling of foods with interpretive nutrition symbols to improve consumers' understanding and use of nutrition information to make their food choices when eating out in restaurants and other food services.
