Why is a Mediterranean diet so good for you?

The Mediterranean diet is widely known to have health benefits but scientists have never worked out what makes it so good for you – until now.
A study led by King’s College London found that the combination of olive oil and salad holds the key to keeping the risk of high blood pressure down.
A large salad with a simple dressing combines the necessary unsaturated fats with nitrate-rich vegetables.
The findings were published in journal Proceedings of the National Academy of Sciences in the USA by scientists at Kings College, the University of California and University of Pittsburgh.
They suggest that the protective effect of the Mediterranean diet comes from the nitro fatty acids it generates, which inhibit an enzyme linked to high blood pressure.
A Mediterranean diet typically includes unsaturated fats found in olive oil, nuts and avocados, along with vegetables like spinach, celery and carrots that are rich in nitrite and nitrates.
