Lessons From The Blue Zones: The World's Healthiest & Longest-living People

What Is A Blue Zone?

Blue zones are regions of the world with populations that exhibit exceptionally high longevity and low incidence of chronic disease. The term originated during a 2004 National Geographic study led by Dan Buettner and demographer Michel Poulain, who marked long-lived villages with a blue pen on a world map.

What Are The Criteria For Blue Zones?

In order to become a certified blue zone, an area must meet three sets of criteria: reliable documentation of birth and death rates, high national longevity compared to the rest of the world, and high local longevity.

What Are The 5 Blue Zones?

The five blue zones are located in

  • Ikaria, Greece
  • Okinawa, Japan
  • Ogliastra Region, Sardinia, Italy
  • Loma Linda, California
  • Nicoya Peninsula, Costa Rica

What Accounts For Longevity Of The Blue Zones?

A whole food plant-predominant diet, regular, low-intensity physical activity, and positive social connections are the main factors that account for the health and longevity of the blue zone populations.
