- Eating a Mediterranean diet high in extra-virgin olive oil has health benefits, a study suggests
- A Mediterranean diet high in nuts can also boost heart health
- Study participants showed fewer heart problems and lower deaths from heart disease
To find out, researchers led by Dr. Ramón Estruch, from the Department of Internal Medicine at the Hospital Clinic of Barcelona, put the Mediterranean diet to the test against a low-fat diet.
They followed participants to track rates of heart attack, stroke and heart-disease-related death. After nearly five years, the results were so striking for one group that the study was stopped early, according to research published online by the New England Journal of Medicine.
The group that showed the least heart problems and lowest rate of heart disease deaths? Those who ate a Mediterranean diet high in extra-virgin olive oil. Coming in at a close second were participants who ate a Mediterranean diet high in nuts.
