Ikaria (Greece) 
Eating lots of fruits, vegetables, beans, whole grains, potatoes and olive oil and smaller amounts of dairy and meat products, together with a committed sense of community, seems to be the secret to longevity on the island of Ikaria. Situated in the Aegean sea eight miles off the coast of Turkey, 1 in 3 Ikarians live into their 90s, often free of dementia and chronic disease.
