Blue Zones

The Blue Zones project emphasizes avoiding premature chronic-disease deaths rather than promising extreme lifespan extension. Blue Zones are demographically confirmed areas where populations live longer and healthier lives than comparison groups. Blue Zones evidence is observational and cannot isolate every causal variable. Modern Blue Zones can lose their longevity advantage when traditional diet, activity, and community patterns change. The five Blue Zones named are Okinawa, Sardinia, Ikaria, Nicoya, and Loma Linda's Seventh-day Adventist community.
