Experts say a new study proves that a Mediterranean diet can help prevent heart disease.
Researchers at the Hospital Clinic of Barcelona tracked 7,000 adults who were at risk for heart attacks or strokes.
Participants who stuck to a Mediterranean diet, along with extra-virgin olive oil or mixed nuts, were 30 percent less likely to develop heart disease.
That was compared to those who consumed a traditional low fat diet.
Officials say it was even more effective than many medications, like Statins, which may also raise the risk of diabetes.
A Mediterranean diet is rich in fresh fruits, vegetables, fish, nuts, olive oil and wine.
It also steers clear of red meats and processed foods.
