Results of a study conducted at the Catalan Institute of Oncology in Barcelona indicated that diet plans high in olive oil, plant-based foods such as fruits, vegetables, legumes, whole-grain cereals, nuts, seeds and fish can cut chances of heart problems.
Published in the American Journal of Epidemiology, the findings support a wealth of research proving the range of health benefits associated with regional diet.
The report stated: "Studies of varying sizes and designs have shown that a Mediterranean diet can reduce the risk of death in people who've had a heart attack, curb the risk of stroke, and boost survival in people living with heart disease."
Figures show that heart disease is the number one killer worldwide, accounting for around 30 per cent of all deaths.
Experts believe that some 80 per cent of heart attacks and related events could be prevented by positive lifestyle changes, such as diet and fitness plans.
