Saturated Fat: Friend or Foe?

Reducing consumption of dietary saturated fat (SFA) has been part of dietary recommendations for many years as a means to prevent cardiovascular outcomes. Yet, recent research has challenged this very basic concept in preventive nutrition. Data have suggested that LDL-C raising effect of dietary SFA may be influenced by its dietary source, cheese having less hypercholesterolemic effects than butter. Observational cohort studies have generally failed to find significant associations between intake of SFA and risk of coronary heart disease. In large intervention studies, substituting vegetable oil rich in polyunsaturated fatty acids for SFA have not yielded consistent results in terms of cardiovascular benefits. In the end, there is no absolute consensus on the importance of SFA in a heart-healthy diet. As emphasized in this chapter, more research is required to put this debate at rest. In the mean time, focusing on whole foods and dietary patterns, without overly emphasizing the importance of SFA in the diet, seems entirely reasonable and appropriate.
