Webinar description:  Diets high in dietary fibre have been shown to reduce the risk of several chronic diseases. Prebiotic dietary fibers, including resistant starch, oligo- and polysaccharides, are fermented by the intestinal microbiota generating metabolites that elicit various benefits to the host. There are many prebiotic fibres inherent in foods such as fruits, vegetables, whole grains, oats, barley, and pulses; however, they can also be isolated and produced commercially for use as functional ingredients and supplements. This webinar will provide an overview of the role of prebiotic fibres as part of a balanced diet, and to explore its effects on digestive, metabolic, and mental health.

Learning Objectives:

  1. To understand the potential role prebiotic fibres on overall digestive, metabolic, and mental health.
  2. To understand the mechanisms for the physiological effects of prebiotic fibres
  3. To learn how to incorporate prebiotic fibres into a healthy, balanced diet

Speaker:  Krista A. Power, PhD (University of Ottawa)

Moderator: Laura Chiavaroli MSc, PhD (University of Toronto)

About the Speaker:   

Krista Power is an Associate Professor at the School of Nutrition Sciences, Faculty of Health Sciences and cross-appointed with Biochemistry, Microbiology, and Immunology, Faculty of Medicine, at uOttawa. Her main research focus is to investigate the role of the intestinal microbiome in mediating the effects of diet on chronic disease. In animal models, her team evaluates the impact of foods enriched in intestinal health-promoting bioactives (e.g., fermentable fibers and polyphenols), on the composition and function of the colonic microbiota and its role in modulating intestinal diseases (i.e., inflammatory bowel disease), metabolic diseases (i.e., obesity), and mental health disorders (i.e., anxiety, depression). In collaboration with clinicians at the Children’s Hospital of Eastern Ontario (CHEO), Dr. Power’s team is also exploring aspects of the microbiota-gut-brain axis in adolescents with eating disorders to identify potential diagnostic and prognostic biomarkers, as well as therapeutic targets.
