Some "healthy" vegetable oils may increase heart risk
It’s become conventional wisdom that vegetable oil is healthier than saturated animal fats. However, a new analysis in the Canadian Medical Association Journal suggests that some vegetable oils may actually increase heart disease risk.
Vegetable oils high in omega-6 but extremely low in omega-3--such as corn oil and safflower oil--do not benefit heart health, according to the new study. A group of participants in an earlier study replaced saturated fat with safflower oil. That lowered their serum cholesterol levels, but the treatment group had significantly increased rates of cardiovascular and coronary artery diseases.
The new analysis concluded that heart-healthy food label claims should not be on products that are rich in omega-6 but not omega-3.
