Dietary fats and oils: Technologies for improving cardiovascular health

Abstract

The role of dietary lipids in the etiology of coronary heart disease (CHD) continues to evolve as we gain a better understanding of the metabolic effects of individual fatty acids and their impact on surrogate markers of risk. A recent meta-analysis of 60 human studies suggests that for each 1% energy replacement of carbohydrates in the diet with saturated fat or trans fat, serum low-density lipoprotein cholesterol concentrations increase by 0.032 (1.23 mg/dL) and 0.04 mmol/L (1.54 mg/dL), respectively. Current dietary recommendations to keep saturated fat and trans fat intake as low as possible, and to increase the intake of cis mono-unsaturated and polyunsaturated fatty acids, as well as growing recognition of these recommendations by consumers and food regulatory agencies in the United States, have been major driving forces for the edible oil industry and food manufacturers to develop alternative fats and oils with nutritionally improved fatty acid compositions. As solutions for use of trans fatty acids are being sought, oilseeds with modified fatty acid compositions are being viewed as a means to provide such solutions. Additionally, oilseeds with modified fatty acid composition, such as enhanced content of long-chain omega-3 fatty acids or conjugated linoleic acid, have been developed as a way to increase delivery of these fatty acids directly into the food supply or indirectly as use for feed ingredients for livestock. New processing technologies are being utilized around the world to create dietary fats and oils with specific physiologic functions relevant to risk factors for cardiovascular disease.
