Anyone familiar with Blue Zones?
« on: August 02, 2015, 06:41:57 AM »
Blue Zones is a concept used to identify a demographic and/or geographic area of the world where people live measurably longer lives. The concept grew out of demographic work done by Gianni Pes and Michel Poulain,[1] 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. Dan Buettner identifies longevity hotspots in Okinawa (Japan); Sardinia (Italy); Nicoya (Costa Rica); Icaria (Greece); and among the Seventh-day Adventists in Loma Linda, California, and offers an explanation, based on empirical data and first hand observations, as to why these populations live healthier and longer lives.

Been reading about these the past day or so.  Very interesting, but I think the whole "plant-based" diet only is misleading.
That said, eating "whole foods" and likely a somewhat calorie-restricted diet is better than 99% of the average person's diet anyway and would probably be an improvement.

I haven't heard them referred to as "blue zones", but I'm familiar with the concept and have investigated some of the claims.

Typically the specifics of the claims are somewhat bogus.  For example, part of the reason Sardinia has disproportionately more old people is that all the young people have been moving off the island for the past century.  In addition, the diet is usually misrepresented:  Okinawans over the past century have eaten what's closer to a fish based diet than a plant based diet, and they also eat far fewer calories than the world average, so you'd expect life extension from caloric restriction.

Still, there might be a grain of truth here and there, and it's interesting to think about.
