Replacing butter (cow) butter, vegetable fats rich in linoleic acid, reduces the level of cholesterol in the blood, but does not affect indicators of cardiovascular disease. A study of American nutritionists published in the British Medical Journal.
Doctors have set a goal to verify the traditional claim of advantage for health of consumption of vegetable fats (in particular, corn, soybean, Flaxseed and sunflower oils) before animals (e.g., cow). Experts have conducted precise analysis of the study MCE (Minnesota Coronary Experiment).
The experiment took place in Minnesota in the years 1968-1973, with the aim to determine the impact of replacing animal fats with vegetable on the incidence of coronary heart disease and mortality caused by the decrease in the level of cholesterol in the blood. In MCE participated 9423 people aged 20-97 years from six nursing homes and psychiatric hospitals.
Nutritionists have discovered those who were replaced in the diet animal fats vegetable compared with the control group, the level of cholesterol in serum, but did not find confirmation of the hypothesis that the linoleic acid rich vegetable oils reduce the risk of mortality from coronary heart disease or other causes.
According to scientists, the publication of incomplete data MCE contributed to the spread in society the opinions about the advantages of vegetable fats animals. Scientists in their study do not provide guidance on the replacement of one type to other oils, but I urge a cautious approach to nutritional recommendations based on incomplete reporting.
In 2009 the American heart Association reported that a diet low in saturated fats and high (5-10 percent of the daily caloric intake) linoleic and omega-6 unsaturated fatty acids useful for the cardiovascular system.
