- Gianni Pes first noted unusually long lifespans in Sardinia’s Ogliastra region, identifying a cluster of longevity that would later be called “blue zones”.
- Michel Poulain validated Pes’s observations and used blue‑colored dots on maps to mark these longevity clusters, coining the “blue zone” label.
- Dan Buettner later popularized the “blue zone” concept, turning the research into a global longevity movement.
- Eric Topol argues the scientific backing for blue zones is weak, urging evidence‑based longevity research.
- Shelley Wood points out the term “blue zone” came from the ink color on a map, not from any scientific significance.
Why it matters: Health‑focused consumers and wellness brands, which rely on blue‑zone hype, face a limited pool of validated longevity sites, risking reduced trust and slower market growth.
