Oil cooking or butter - the secret to heart health

The idea that butter is a harmful food for the heart may prove wrong if the data from a survey of some 50 years ago, analysed now, is correct.

Researchers from the University of North Carolina Medical School have recently published an article in the British Medical Journal, which says that cooking with corn oil can be more harmful to the heart than cooking butter. The findings came from a careful regime and a documented diet of some, even against their will.

The team of researchers, reports Qwartz Media, analyzed the unpublished data collected between 1968 and 1973 in a controlled study of more than 9,400 men and women at a hospital centre and six psychiatric hospitals in Minnesota.

A group of patients were given butter - cooked food and other hydrogen oils, and others prepared with common margarine.

Researchers found that the risk for life was 22 percent higher for those with a vegetable diet, but considering that the results of the old study were never published, suggest that food experts overestimated the value of vegetable oils at the expense of butter.
