The preliminary research was presented at the American Heart Association’s Prevention, Lifestyle and Cardiometabolic Health Scientific Sessions 2020.
The study shows that replacing a mere five grams of margarine, butter or mayonnaise with the same amount of olive oil was associated with up to a 7% lower risk of coronary artery disease. To put that into context, five grams is about a half pat of butter or margarine and one teaspoon of mayonnaise or fatty dairy products.
“Don’t just add olive oil to your regular diet. Substitution is what’s important here,” said study author Dr. Frank Hu, who chairs the department of nutrition at Harvard T.H. Chan School of Public Health.
The results echoed a 2013 study of over 7,000 people, one of the largest ever done. It found people who followed a Mediterranean diet supplemented with extra virgin olive oil for five years had a 30% lower risk of heart attack or stroke.
