Abstract: Cardiovascular diseases (CVD) are one of the most important causes of death in Canada. They are characterized by various conditions affecting the heart and/or the blood vessels, of which a set of risk factors are involved. Many risk factors such as blood lipids levels and hypertension could be modulated, notably by diet and healthy lifestyles. However, the impact of certain nutrients such as dietary lipids and their implications in CVD remains controversial in the scientific community. Precisely, cohort studies have shown that the incidence of CVD can be increased by the consumption of saturated fatty acids (SFA), while other studies have found that the impact of dietary SFA on cardiovascular health could potentially depend on the source of SFA consumed. This thesis presents the results of a multicenter clinical study which had as a main objective to investigate the impact of SFA from different dairy products, namely cheese and butter on various cardiometabolic risk factors. Results of this study suggest that consumption of SFA from cheese does not have the same impact on low-density cholesterol (LDL-C) levels that consumption of SFA from butter. The effect of SFA consumption from cheese on LDL-C is also modulated according to baseline LDL-C levels of the men and women who participated in the study. This high-quality scientific study provides new insights into the effect of SFA on cardiometabolic risk. However, more studies are needed to better understand the effect of the food matrix on other cardiovascular risk markers.
