In The Ikaria Way, Greek American chef Diane Kochilas offers a roadmap for people who want to incorporate aspects of the Mediterranean island's "Blue Zone" diet into their lives. As one of the world's five designated "Blue Zones", Ikaria, a small Greek island in the eastern Aegean, has lower rates of chronic disease than most other places, and its more than 8,000 full-time residents have some of the longest life expectancies in the world. In fact, one-third of Ikarians live past 90 years of age, and factors such as strong social and family ties, exercise that is integrated into daily life and frequent napping are thought to be why these island inhabitants often live to be centenarians. Another important contributing factor is what they eat. (BBC News)
