I thought it was interesting to hear Dan Buettner’s counter-arguments like how they viewed different life event records from different places. I don’t know what the gold standard is, but it sounded good. That the blue zones isn’t specifically in some country or region but could even be smaller down to villages was also persuasive.
It makes sense anyway that the interventions help with longevity, at least not harm it. Reduced atherogenic lipoprotein levels and BP from diet have an effect as well.
What’s interesting is they apply concepts learned to local governments like in Fort Worth, Texas, via their company, to improve population health with claimed successes like a reduction in BMI. Good work everyone!
Yes, his unique approach of replicating the Blue Zones concept to the populations/communities in US demonstrates environment plays overwhelmingly dominant role in healthspan preservation and perhaps longevity. In other words, its not unique to certain genetic subsets.
