Are blue zones real? Answering that question is harder then ever

From the article: "clerical errors, natural disasters, and pension fraud were better explanations for the proportion of centenarians “discovered” in these discrete regions of the world."

That was discovered in Japan around 2010.[1] The Tokyo municipality sent out people to visit everyone over 100 to find out what they were doing right. What they found was that about 80% of them were unaccounted for, but collecting benefits.[1][2]

A 2024 Ig Nobel was awarded to work debunking Blue Zones.

IMO the whole concept is one of those Occam’s razors that proves especially sharp.

This really captures the reality of longevity, at least in US culture. Whether or not blue zones are verifiable or real, the ingredients to statistical longevity are well understood to minimally include: eat better and maintain a level of fitness.

Those are not easy to do when laziness, sedentary device time and fast food options are just so easily available. So instead, we end up with frozen meals that almost certainly don't contain the same nutrients and definitely don't include the same effort as having to prepare a meal by hand while walking about the kitchen.

Medicine has extended longevity, but the relative ease of our senior years is perhaps robbing us of the quality of that bonus time.

Blue zones were always just eat healthy, exercise, and having friends.

I believe that these things almost certainly help longevity as a number of independent studies into each of these show that, and it’s intuitively obvious

Okay but surely there must be areas which have better longevity on average? It is probably tied mostly to social culture and walkability, is my guess.

Speaking entirely anecdotally – I have come across a lot of really old but still active Sicilian people. People that, at their age, would be immobile and in a nursing home in America, but instead go for walks daily, see friends in the town, etc.

Why not simply use median life expectancy, which is more robust to fraud and outliers, instead of "number of centenarians"?

My doctor always says “There are three little things that will give you the best chance at living a long and healthy life. Eat a little better, move around a little bit, and get a little more sleep”

I wrote a short story about life expectancy last year.

Inspired by some random HN comment.

I still believe that minimally processed, varied foods and limited red meat are good for health.

As the joke goes, birth certificates kill.

Longevity research is the most overhyped, commercially driven scam and fraud hotspot in modern science. Anti-aging docs and researchers print beaucoup bucks milking the rich narcissistic boomer cow who doesn't want to age, can't accept their mortality and is willing to spend a fortune trying to stave off the inevitable.

> In 2021, Adventist Health used the blue zones brand to market a $600 million Miami luxury tower that, in addition to boasting a “blue zones center” combining longevity medicine and advanced diagnostics, featured on-site cosmetic and plastic surgery.

The page immediately reminded me of that "What is a Dickover" post :)

Maybe not but anecdotes are

Blue zones have been utterly, thoroughly debunked. There’s no reason to still ask this question in 2026 unless a new/unusual population or lifestyle is emerging.
