Deep dives
The Blue Zones Debate
The concept of Blue Zones refers to regions around the world where people are believed to live significantly longer lives. However, scrutiny over this claim reveals that these areas, such as Sardinia, Italy, and Okinawa, Japan, often have troubling social issues, including low literacy, high crime rates, and poor health metrics. Studies initially suggesting a correlation between these regions and longevity are increasingly viewed as flawed due to inconsistencies in mortality data and record-keeping practices. Investigations show that many individuals reported to be over 100 years old may have inaccuracies in their documentation, challenging the notion of Blue Zones as exemplars of healthy living.
