Blue zone

Uncommon card · No. 75524

The blue zone theory represents a region where some people self-attest to exceptional longevity, which has been variously attributed to lifestyle. Favorable factors under research may be physical activity, low stress, frequent social interactions, a predominantly plant-based diet, and low disease incidence. The name blue zones derived simply during the original survey by scientists, who "used a blue pen on a map to mark the villages with long-lived population." Suggested blue zones include Okinawa Prefecture in Japan, Nuoro Province and Bolotana in Sardinia, Italy, the Nicoya Peninsula in Costa Rica, and Icaria, Greece. Based on an absence of scientific evidence, the concept of blue zones is commonly challenged as unproven. Subsequent research contradicted initial claims, such as for Okinawa, which experienced substantial decline in life expectancy during the 21st century, and Nicoya, where people born after 1930 did not have exceptional longevity compared to the broader national population.
