While many patients might still need statins, those sticking to such habits might be able to have a far lower dose, reducing the risk of any side-effects such as muscle pain.
“It could allow patients to get the benefits of statins but without the side-effects,” he said, urging doctors and patients to think far more about lifestyle.
The study tracked 1,200 Italians with heart disease over seven years, and participants recorded their food intake. Adherence to the Mediterranean diet was appraised under a nine-point scoring system. Over seven years, there were 208 deaths.
After controlling for age, sex, education, exercise, smoking, blood pressure, cholesterol levels, diabetes and cancer, a two-point increase in the Mediterranean diet score was linked with a 21 per cent reduced risk of death.
The closest adherence to the Mediterranean diet was associated with a 37 per cent lower risk of death compared with the bottom category.
A previous study of 92 trials involving 200,000 patients found that people with heart disease were 18 per cent less likely to die early if they took statins.
Researchers said the next step would be to investigate why exactly the Mediterranean diet appears to reduce the risk of dying early.
Prof de Gaetano said: ”This was an observational study so we cannot say that the effect is causal. We expect that dietary effects on mediators common to chronic diseases such as inflammation might result in the reduction of mortality from any cause but further research is needed.”
British experts said the “powerful anti-inflammatory effects” of foods such as olive oil, oily fish, nuts and vegetables was likely to make the difference.
Dr Aseem Malhotra, a London cardiologist, said: “The results of this robust observational study are quite extraordinary.
“The Mediterranean diet is more powerful than any drug at reducing death rates in patients with cardiovascular disease.”
Prof Jeremy Pearson, Associate Medical Director of the British Heart Foundation, said: “It is good to know that even if you already have a history of cardiovascular disease, adhering to a Mediterranean diet reduces the risk of death.
“This study suggests that even if you are already receiving medical care, if you add a Mediterranean diet, it will have further benefit. Maintaining a healthy lifestyle, even if you have had a heart attack or stroke is really important and continues to benefit you.”
