Haven't the "Blue Zones" been thoroughly debunked? They were found to be due to a combination of fraud and unreported deaths, for the most part.

What? Are you saying Japan is lying about their longevity statistics, for example? Where have you been hearing this, out of interest?

There have been several mag/news articles - that seemed thoroughly respectable - saying that the original author was a victim of widespread inaccuracies in the actual death records of all the bluezones, along with widespread fraud in old-age and retirement payments. Okinawa was especially corrupt in this area.

I took a peek. I think you saw a lot of coverage in non-scientific press because one Dr Saul Justin Newman was awarded an ig nobel (not a terribly serious, academically rigorous award) and the non-scientific press did what they do. I think you may be putting too much weight on what appears to be a set of statistical arguments being made by one researcher to say it's been "thoroughly debunked", but I also see that it was never a very well-informed observation in the first place.

Sounds like some of the debunkings were sketchy too https://deepcast.fm/episode/blue-zones-teij

But yes if there ever was anything to blue zones it doesn't seem like there is any more.

I'm skeptical of anyone with three NYT bestsellers.

The plant-based physician is the author of the New York Times bestselling titles How Not to Die, How Not to Diet, and How Not to Age.

No, they’re actually that old and healthy.

The relationship between protein intake and mortality is still controversial. We prospectively examined the associations of dietary protein sources with all-cause mortality risk in the Isfahan cohort study (ICS). A total of 5431 participants, aged ≥ 35 years, were enrolled in the ICS, in 2001 and followed through 2013. The frequency of protein intakes from different sources was estimated through a validated food frequency questionnaire at baseline. Any new case of death was recorded over the follow-up duration. Hazard ratio (HR)s and 95% confidence interval (CI)s were estimated through Cox proportional hazards regression models. During a median follow-up of 11.3 years, 483 deaths were documented. Higher intakes of plant proteins (HR = 0.64, 95% CI 0.46, 0.91) and animal proteins (HR = 1.52, 95% CI 1.13, 2.05) were associated with a decreased and increased risk of mortality, respectively. Additional adjustment for some mediators did not considerably affect the associations for animal protein (HR = 1.55, 95% CI 1.15, 2.09), whereas led to a tendency towards lower risk for plant protein in the top quintile compared with the bottom one (HR = 0.67, 95% CI 0.48, 0.95; P trend = 0.06). Among specific major sources, higher intakes of nuts and fish were associated with a 27% (95% CI 0.58, 0.93) and 21% (95% CI 0.62, 1.01) lower risk of mortality, respectively. The inverse association between plant protein and mortality risk might be mediated by some metabolic disorders. However, our results suggest an independent positive association for animal protein and all-cause mortality.
