I HAD BEEN TOLD THE SCIENCE WAS SETTLED: New Research Shows Vegetable Oils Are Not Good for Heart Diseases.

The belief that vegetable oils replacing saturated fats improve heart health dates back to the 1960s, when studies showed that these oils lowered blood cholesterol levels. Several studies have been conducted since then that suggests the same conclusion.

However, the conclusion that linoleic-acid dietary interventions can reduce the risk of heart attacks have never been shown in randomized controlled trials, which is considered the gold standard in medical research.

The Minnesota Coronary Experiment (MCE) has unpublished results with the conclusion that the intervention lowered cholesterol levels, but it made no difference in heart attack risks, deaths due to heart disease or overall deaths.

Chris Ramsden, a medical investigator, and colleagues came across the study and recovered the data, Medical Xpress reported. They performed analyses which confirmed the results of the experiment. The autopsy reports they also uncovered revealed that the corn oil group has nearly twice the number of heart attack occurrence than the control group.

Why did those reports go unpublished for 50 years?
