I don't think that is right. In the Blue Zones marketing material, they characterise Loma Linda's 9000 Adventists, who make up 40% of the population, as living a decade longer on average. That is the claim being investigated. This claim is hard to reconcile with the CDC's official numbers which show a typical life expectancy for the entire area, unless living next to Adventists somehow lowers the life expectancy for the remaining 60% of the population, which would be far more interesting.
