Patrick Couture received his medical degree from Laval University in Quebec City. He completed his residency in Internal Medicine and a PhD in physiology at Laval University and the University of Montreal before heading to Tufts University in Boston, MA, for a research fellowship at the Jean-Mayer USDA Human Nutrition Research Center on Aging. Upon returning to Quebec City, he joined the CHU Research Center and the Institute of Nutrition and Functional Foods, where he contributed to the establishment of a clinical research center focused on nutrition and lipoprotein metabolism. Dr. Couture is currently a professor in Laval University’s School of Medicine, and he was the director of the university’s residency training program in internal medicine from 2007 to 2012. Dr. Couture is currently the director of the Lipid Apheresis Program at the Laval University Medical Center, and he is also involved in the clinical care of patients with various lipoprotein disorders.

Investigate the impact of dietary fatty acids on lipoprotein metabolism in patients with diabetes

Diabetes and pre-diabetes are metabolic disorders affecting more than 15% of the world’s population. The prevalence of these disorders is currently on the rise, mainly due to the increasingly sedentary lifestyles associated with rising obesity rates and aging of the population. Because diabetes and pre-diabetes are so closely associated with major health problems such as high blood pressure, high blood cholesterol and cardiovascular disease, they have a tremendous impact on society’s healthcare costs. Significant efforts should therefore be dedicated to tackling this problem from a societal perspective. Dr. Couture’s interests in nutrition led him to uncover the effects of various dietary fatty acids on lipoprotein kinetics and on the expression of key genes involved in intestinal lipid metabolism in patients with diabetes and pre-diabetes. His work is funded by grants from the Canadian Institutes of Health Research, Fonds de recherche du Québec (Santé) and industry.
