Reducing intakes of saturated fats in the diet and consuming polyunsaturated fats instead may reduce the risk of coronary heart disease up to 19 percent, according to a new study.
The study analyzed eight trials, which provided data on 13,614 participants and 1,042 coronary heart disease events (1). For every 5 percent increase in polyunsaturated fat consumption, the researchers reported a 10 percent reduction in the risk of coronary heart disease (CHD).
The study supports the widely supported theory that saturated fats are detrimental to heart health. The findings suggest that polyunsaturated fats would be a preferred replacement for saturated fats for better heart health, the researchers commented.
The study may have implications for recommended daily intakes of omega-3 fatty acids with current guidelines from the U.S. Institute of Medicine (IoM) stating a range between 5 and 10 percent from polyunsaturated fats. The findings also suggest that an upper limit of 10 percent energy consumption from polyunsaturated fats may be too low, as the participants in these trials who reduced their risk were consuming about 15 percent energy from polyunsaturated fats.
However, few weeks ago, a meta-analysis reported contradictory evidence (2): data from almost 350,000 subjects obtained from 21 studies indicated that dietary intakes of saturated fat are not associated with increases in the risk of either coronary heart disease (CHD) or cardiovascular disease (CVD).

A new study has shown that people with metabolic syndrome are less able to process vitamin E than the normal population. As this population suffers from a high visceral lipid burden, any reduction in the levels of this potent fat-soluble antioxidant is of concern and suggests that dietary recommendations of vitamin E intake for this group should be revised upward. Metabolic syndrome is extremely common in the Western world and is closely associated with the development of atherosclerosis and type 2 diabetes.
