People in Dan Buettner's 'blue zones of longevity' who eat mostly plant foods and protein from nuts and fish.

Healthiest diets worldwide are:

• Mediterranean diet

• Nordic diet

• Okinawa diet

The population of the Mediterranean basin has a high life expectancy compared to the rest of Europe. The Mediterranean diet emphasises vegetables, fruit, whole grains and fish.

The Okinawa diet is based on the practice of eating something from the land and sea every day. Its 'top longevity foods' include bitter and yellow melons, soy and tofu products, garlic, Japanese spinach, brown rice, green tea and shitake mushrooms.

Plant-based foods, green leafy and root vegetables, berries and oily fish such as salmon, mackerel or herring are the basis of the Nordic diet.
