Blue Zone – Wikipedia

February 7th, 2019 5:45 pm

Blue Zones are regions of the world where Dan Buettner claims people live much longer than average. The term first appeared in the November 2005 National Geographic magazine cover story "The Secrets of a Long Life" by Buettner.[1] He identified five areas that Buettner considers "Blue Zones": Okinawa (Japan); Sardinia (Italy); Nicoya (Costa Rica); Icaria (Greece) and among the Seventh-day Adventists in Loma Linda, California. He offers an explanation, based on data and first hand observations, as to why these populations live healthier and longer lives. The term "Blue Zones" is trademarked by Dan Buettner.[2]

The concept grew out of demographic work done by Gianni Pes and Michel Poulain[3] outlined in the Journal of Experimental Gerontology,[4] who identified Sardinia's Nuoro province as the region with the highest concentration of male centenarians. As the two men zeroed in on the cluster of villages with the highest longevity, they drew concentric blue circles on the map and began referring to the area inside the circle as the Blue Zone. Together with demographers Pes and Poulain, Buettner broadened the term, applying it to validated longevity areas of Okinawa, Japan and among the Seventh-day Adventists in Loma Linda, California. Buettner and Poulain, under the aegis of National Geographic, then identified and validated longevity hotspots in Nicoya, Costa Rica and Icaria, Greece.

The five regions identified and discussed by Buettner in the book The Blue Zones: Lessons for Living Longer from the People Who've Lived the Longest:[5]

Residents of these places produce a high rate of centenarians, suffer a fraction of the diseases that commonly kill people in other parts of the developed world, and enjoy more years of good health.[11]

The people inhabiting Blue Zones share common lifestyle characteristics that contribute to their longevity. The Venn diagram at the right highlights the following six shared characteristics among the people of Okinawa, Sardinia, and Loma Linda Blue Zones:[12]

In his book, Buettner provides a list of nine lessons, covering the lifestyle of blue zones people:[13]
