The study was conducted from June to October 2009 on over 1,400 of the island's some 8,000 residents, divided into elderly and middle-aged groups and assessing lifestyle, diet, clinical and other factors.

Thirteen percent of those polled were over 80 years old, while 1.6 percent of men and 1.1 percent of women were over 90. "Fish, fruit, vegetables, legumes and tea shield the cardiovascular system. Moreover, daily use of olive oil is beneficient to sexual activity and, if added to the moderate consumption of coffee in the afternoon 'siesta', form the ingredients that may compose the secret of longevity," the researchers said.
The study found that the elderly had healthier eating habits and took midday naps more regularly than younger islanders, presenting lower depression rates. And although the risks of high blood pressure, cholesterol or diabetes are the same as in other parts of Greece, they manifest much later among Ikarians, said professor Christos Pitsavos, a co-author of the study. Pitsavos added that genetic background could also explain the results.
