The Blue Zones

Buettner's original Blue Zones book launched a genuine public health movement, and rereading why is easy — the on-the-ground reporting is vivid, the Power 9 framework is memorable and actionable, and National Geographic's editorial standards give the research credibility it would otherwise lack as popular science. The observational nature of the data means causal claims should be held loosely, but as a case for community, purpose, and plant-forward eating, the argument is compelling and well-told.
