The ultimate goal of our research team is to elucidate the potential of diet to prevent and treat chronic diseases, primarily heart disease, cancer, and diabetes. Our research is clinically based. Dietary trials allow us to also assess mechanisms in vivo by which diet and/or its components alter risk for disease. We have spent considerable time assessing the glycemic index of foods, and have identified legumes and traditional methods of processing as producing a low-glycemic index (e.g., white pasta - low vs. white bread - high). We have and continue to carry out research on vegetable proteins and their potential health benefits (e.g., soy, gluten, and other cereal and vegan proteins). Most recently we have started to combine foods with cholesterol lowering actions (soy, viscous fibers, oats, barley, plant sterols and nuts - almonds) in a single diet to lower serum cholesterol, what we have termed as “dietary portfolio.”
We have demonstrated that early statin-like effects can be achieved under highly controlled conditions. In the real world this dietary approach has a somewhat dampened level of efficacy, but remains a highly effective dietary approach to cholesterol reduction. We continue to carry out studies on low-glycemic index diets, and the quest to find new low-glycemic index foods continues. We also work in collaboration with the food industry on a diverse spectrum of food products and food components ranging from macronutrients to phytochemicals.
With the support of the Institute of Nutrition, Metabolism and Diabetes (INMD) of Canadian Institute of Health Research (CIHR) we are establishing a Nutrition Trialists Network (NTN) to carry out major diet trials nationally and internationally and to link with exercise experts and trialists to form a comprehensive lifestyle program for the prevention and treatment of CVD, Diabetes and other chronic disease.
We are also putting together a Chronic Disease and Clinical Trail Centre at the UofT to link with the Centre for Child Nutrition and Health (CCNH) in the Nutritional Sciences department.
