WHO Collaborating Centre for Nutrition Policy for Chronic Disease Prevention

At a Glance

  • Dr. L'Abbé's work aims to provide an evidence base to support sound public health nutrition policy.
  • Research areas currently of interest include health claims on foods, front-of-pack labelling, children’s marketing on foods, nutritional quality of packaged and restaurant foods, menu labelling, dietary intakes and patterns of the Canadian population using national nutrition surveys, food fortification, food-like natural health products, trans fat, sodium, and sugar.
  • The L’Abbé Lab’s research and food supply data have been used by Health Canada, the Ontario government, Toronto Public Health, Heart and Stroke Foundation, food industry, WHO/FAO and others to support monitoring, policy development and consumer programs.

McHenry Professor and Chair) in the Department of Nutritional Sciences, Temerty Faculty of Medicine at the University of Toronto, where she leads a research group on Food and Nutrition Policy for Population Health. She is also Director of the WHO Collaborating Centre on Nutrition Policy for Noncommunicable Disease Prevention. Dr. L’Abbé is an expert in public health nutrition, nutrition policy, and food and nutrition regulations, with a long career in in mineral nutrition research. Her research examines the nutritional quality, marketing and labelling products in the Canadian food supply, dietary intake patterns, and consumer research on food choices related to obesity and chronic disease. In 2018, Dr. L’Abbé was named a Member of the Order of Canada for her contributions to the health of Canadians as a champion of nutrition. She is an advisor to national health groups, Chairs the Pan American Health Organization (PAHO) Technical Advisory Group on Cardiovascular Disease Prevention through Dietary Salt Reduction, and a member of the World Health Organization (WHO) Nutrition Guidance Expert Advisory Group on Diet and Health. Additionally, Dr. L’Abbé was co-chair of the Canadian Trans Fat Task Force, led the Trans Fat Monitoring Program and served as Chair and vice-Chair of the Canadian Sodium Working Group.

Dr. L’Abbé holds a PhD in nutrition from McGill University and has authored over 300 peer-reviewed scientific publications, book chapters and government reports.

Research Synopsis 

Dr. L’Abbé’s research group aims to provide an evidence base to support strong public- and private-sector public health nutrition policies concerning food labelling (e.g., nutrient content and health claims, front-of-package and menu labelling), marketing of foods to children, the nutritional quality of Canada’s packaged food supply (e.g., nutrient profiling, food fortification), and the dietary intakes and patterns of the Canadian population. Research approaches include: (i) consumer surveys on knowledge, attitudes and behaviours related to foods and nutrition; (ii) assessments of the nutritional quality, labelling and marketing of Canadian foods; (iii) the development and evaluation of mobile apps to motivate and enable consumers to improve their dietary intakes; and, (iv) the development of methods for assessing and modelling population intakes, using national food consumption surveys. Notably, Dr. L’Abbé’s team has developed and maintains 2 large databases containing nutrition and other label information for ~100,000 packaged foods collected in-store between 2010-2017 and via web in 2020 (Food Label Information Program, FLIP) and ~50,000 restaurant foods from the leading retailers and chain restaurants in Canada (Menu-FLIP). These databases are used in much of the research conducted by Dr. L’Abbé’s group. Other research interests include developing and testing consumer tools and apps to facilitate healthier food choices (e.g., FoodFLIP, One Sweet App, Big Life Salt Calculator), and exploring consumer nutrition knowledge, attitudes, behaviours and dietary intakes through online surveys administered to nationally representative samples of Canadian consumers. Research from Dr. L’Abbé’s lab and the FLIP food supply data have been used to support the monitoring, policy development and consumer programs of Health Canada, the Government of Ontario, Toronto Public Health, Heart and Stroke Foundation, the WHO/FAO, and the food industry, among others.
