The extent to which a high intake of saturated fat (SFA) increases the risk of cardiovascular disease (CVD) has become a controversial topic. Dietary SFA primarily raise LDL-cholesterol, while having relatively neutral impact on other key CVD risk factors. Recent epidemiological data is also challenging the concept that SFA increase the risk of CVD. Meta-analysis of data from early intervention studies has suggested that replacement of dietary SFA by PUFA (mostly linoleic acid) reduces the risk for CHD. On the other hand, meta-analyses of population studies have failed to find an association between dietary SFA intake and the risk of CHD. More recently, higher intakes of SFA from dairy have actually been associated with a lower CHD risk. This has emphasized the importance of considering the food matrix from which dietary SFA are provided when assessing cardiovascular outcomes. Focussing on SFA in dietary guidelines may not have yielded full benefits in terms of cardiovascular prevention.
Dr. Benoit Lamarche, PhD
Benoît Lamarche, PhD is Full Professor at the
School of Nutrition and Chair of Nutrition at Laval University. He has
published more than 270 peer-reviewed papers in areas related to diet and its
impact on metabolic syndrome, obesity, inflammation and dyslipidemia. His
research on the association between small dense LDL particles and the risk of
CHD, on the effect of trans fat from industrial and ruminant sources on blood
lipids and on Mediterranean diet is highly cited. He has also recently
developed a research interest in sport nutrition. He has received numerous
awards, including awards from the Société Québécoise de lipidologie, nutrition
et métabolisme (Prix des Fondateurs, 2013), the Canadian Nutrition Society
(Centrum New Investigator Award, 2011), the Utrech Group and the International
Dairy Federation (Wiebe Visser Bi-annual International Nutrition Award, 2004).
Benoît Lamarche is an Olympian (1984,1988) in long track speed skating.
