• Vieillir en force: nutrition et santé musculaire avec Dre Stéphanie Chevalier / Aging Strong: Nutrition and Muscle Health with Dr. Stéphanie Chevalier

  Les personnes âgées représentent le groupe démographique qui croît le plus rapidement au Canada, avec 19 ? la population âgée de 65 ans et plus, soit environ 7 millions de personnes. L’exercice, l’activité physique et la nutrition sont des éléments essentiels d’un vieillissement en santé, contribuant au maintien de la santé musculosquelettique et à la réduction du risque de sarcopénie. Dre Stéphanie Chevalier est diététiste, professeure agrégée à l'École de nutrition humaine de l’Université McGill et chercheuse à l’Institut de recherche du CUSM. Spécialiste du métabolisme des protéines, elle étudie le rôle des nutriments dans la perte musculaire liée au vieillissement et à certaines maladies comme le cancer et le diabète. Ses recherches récentes portent sur les liens entre nutrition, santé musculaire et cognition chez les aînés. Son programme est financé par les IRSC, le FRQS, la Société canadienne du cancer et la FCI. Elle est présidente de la Société canadienne de nutrition et membre du comité directeur de l’étude NuAge. Dans cet épisode, Dre Chevalier abordera le rôle de la nutrition dans le vieillissement, un sujet au cœur des préoccupations liées au vieillissement en santé. Please note that this podcast has been recorded in French; however, you may view the script in English hereOlder adults represent the fastest-growing demographic group in Canada, with 19% of the population aged 65 and over—approximately 7 million people. Exercise, physical activity, and nutrition are essential components of healthy aging, helping to maintain musculoskeletal health and reduce the risk of sarcopenia. Dr. Stéphanie Chevalier is a registered dietitian, Associate Professor at the School of Human Nutrition at McGill University, and a researcher at the Research Institute of the McGill University Health Centre. A specialist in protein metabolism, she studies the role of nutrients in muscle loss associated with aging and certain diseases such as cancer and diabetes. Her recent research focuses on the links between nutrition, muscle health, and cognition in older adults. Her research program is funded by CIHR, FRQS, the Canadian Cancer Society, and the Canada Foundation for Innovation. She is President of the Canadian Nutrition Society and a member of the steering comity of the NuAge longitudinal study on nutrition and aging. In this episode, Dr. Chevalier will discuss the role of nutrition in aging—an issue at the heart of healthy aging concerns.

• Digest This: The Truth About Your Gut with Kelsey Moore

  Digestive health plays a crucial role in overall well-being, impacting everything from nutrient absorption and immune function to mental health. At the heart of this system is the gut microbiome—a complex network of microorganisms that helps regulate inflammation, metabolism, and even the risk of chronic diseases. Despite its importance, digestive health is often misunderstood, with myths about probiotics, fibre, gluten, and conditions like irritable bowel syndrome (IBS) and celiac disease continuing to circulate widely. Kelsey Moore is a Registered Dietitian with a retail nutrition background and experience in the digestive health space. Kelsey graduated from The University of British Columbia in 2019. She started her career as a sports dietitian and then moved into the retail space where she worked as a Nutrition Operations manager for a local BC food retailer. She is currently working as the Senior Account Manager of Nutrition for the Canadian Digestive Health Foundation where she works with food and supplement brands to help deliver digestive health resources to Canadians. Kelsey is passionate about providing evidence-based information on digestive health and is currently on track to becoming a Monash FODMAP-trained dietitian. In this episode, Kelsey discusses common myths and misconceptions around digestive health. This podcast is in collaboration with the Canadian Digestive Health Foundation (https://cdhf.ca/en/).

• Canadian Food Regulations: Are they barriers or facilitators to food innovations in Canada? with Dr. William Yan, Dr. Samuel Godefroy and guest host, Teresa Mastrodicasa

  Over the past decade, food and food systems have emerged as key to tackling non-communicable diseases, sustainability, and food security. This has spurred major investments in technologies that transform how we produce and consume food. Yet, regulation and policy remain major barriers to innovation, access, and identifying foods that support healthy diets. Dr. William Yan earned his Ph.D. in Medical Microbiology and Infectious Diseases from the University of Alberta and joined Health Canada in 1995. As Director of the Bureau of Nutritional Sciences (2010–2022), he led key Healthy Eating Strategy initiatives, including sodium reduction, trans fat elimination, and front-of-package labelling. Now retired, he is a CNS-SCN Fellow, and teaches at the University of Ottawa. Dr. Samuel Godefroy, former Director General of Health Canada’s Food Directorate and Vice Chair of the Codex Alimentarius Commission, has over 25 years of experience in food regulatory science and policy. He is President of both the International Union of Food Science and Technology and the Global Food Regulatory Science Society. Currently, he is a Full Professor at Laval University, where he leads the Food Risk Analysis and Regulatory Excellence Platform. In this episode, Dr. Yan and Dr. Godefroy discuss regulation and policy as a barrier and facilitator to addressing food system challenges, with a primary focus on food manufacturing and consumers as targets for food system modernization. This podcast is sponsored by Protein Industries Canada.

• Why We Store Fat Differently: The Science Behind Metabolism and Obesity with Dr. Kafi Ealey

  Research shows that adipose (fat) tissue isn’t just stored energy—it plays a critical role in metabolism, inflammation, and disease risk. Biological, environmental and nutritional factors contribute to differences in how people store fat and develop conditions such as obesity and type 2 diabetes. Dr. Kafi Ealey is an assistant professor in the School of Nutrition at Toronto Metropolitan University. Dr. Ealey obtained her MSc and PhD from the Department of Nutritional Sciences at the University of Toronto and completed postdoctoral training at the RIKEN Center for Integrative Medical Sciences in Yokohama, Japan, as well as in the Department of Translational Medicine at the Toronto Hospital for Sick Children Research Centre. Dr. Ealey’s research is focused on understanding the biological and cellular processes that govern the diverse functions of metabolic tissues to promote overall health. Her work employs a range of experimental models to determine how nutrition can affect fat storage, the immune system, and how the body uses energy, and helps us better understand how to prevent or manage chronic metabolic diseases. Dr. Ealey is particularly passionate about examining the biological variations in metabolic systems that contribute to racial and ethnic disparities in the prevalence of obesity-related conditions, including type 2 diabetes. In this episode, Dr. Ealey discusses how fat storage and metabolism vary across individuals and populations, and why these differences matter for health.

• Stronger for Longer: The Power of Exercise in Healthy Aging with Dr. Lora Giangregorio

  Older adults are the fastest-growing demographic in Canada, yet gaps in care persist, including limited healthcare access, social isolation, and rising cognitive decline. Addressing these challenges through diet and physical activity is key to promoting healthy aging and quality of life. Dr. Lora Giangregorio is a Professor in the Department of Kinesiology and Health Sciences at the University of Waterloo and Tier 1 Canada Research Chair in Bone Health and Exercise Science. She leads the Bone Health and Exercise Science Lab, also known as the BonES lab. The BonES lab team leads research on physical activity for older adults and people with osteoporosis. Dr. Giangregorio is a member of the Scientific Advisory Council for Osteoporosis Canada and was on the leadership team that developed the 2020 Canadian 24-hour Movement Guidelines. She also led the Exercise Working Group for the 2023 Clinical Practice Guidelines for Management of Osteoporosis and Fracture Prevention in Canada. In this episode, Dr. Giangregorio discusses the vital role of exercise in supporting mobility, bone health, and muscle strength in older adults.
