A new study links the consumption of oil-based products - such as soft, trans fat-free margarines to a significant reduction in heart disease risk. Researchers have found that the consumption of this type of products is more efficient in reducing the risk of cardiovascular problems than, for example, a decrease in smoking or an increased fruit consumption.
The current study, performed in Poland by Zatonski W. and Willett W. and published in the "British Medical Journal", focuses on changes in dietary fat, confirming that polyunsaturated fats are more beneficial to the heart than saturated fats and that a low intake of trans fatty acids should be maintained to reduce the risk of cardiovascular problems. An increased intake of
polyunsaturated fats was found to be responsible for a decrease in mortality due to coronary heart disease. The findings of this study are consistent with results of other studies conducted in the United States, United Kingdom and Australia within the past decade.
Fat affects the cardiovascular system by building up in the walls of the arteries and leading to arteriosclerosis; this process begins in childhood, and recent research has shown that children nowadays consume too much fat, particularly saturated fat. Approximately half of teens have more than the recommended daily dietary cholesterol level.
The researchers' results come in support of the fact that simple changes in the diet can prove life-saving in the long run. For example, replacing butter with a soft, trans fat-free margarine ca lower cholesterol levels and thus, the risk of heart disease as well.
This is a conclusion confirmed by the American Heart Association, after numerous studies in the U.S. showed that the intake ratio of dietary saturated to unsaturated fats is inversely related to the incidence of heart disease. Coronary heart disease is currently the primary cause of death among American males and females.
