For 1 / 4 of a century, researchers and the general public have tried to grasp why individuals in so-called “blue zones” reside a lot longer than elsewhere.
Saul Newman, a researcher at College School London (UCL), believes he has the reply: Truly, they do not.
Newman believes that whereas blue zones are well-known in information articles, cookbooks and even a latest Netflix documentary collection, they’re really only a byproduct of unhealthy knowledge.
He mentioned individuals in 5 areas lived considerably longer than life-style components akin to weight loss program or social relationships – Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; and Ikaria, Greece ; and Loma Linda, Calif. — may very well be defined by pension fraud, clerical errors and an absence of dependable delivery and demise information.
Dan Buettner, the American creator and explorer credited with coining the time period “Blue Zones,” didn’t reply to a request for remark.
To look at the blue zone claims, Newman, a senior analysis fellow at College School London’s Middle for Longitudinal Research, analyzed a considerable amount of inhabitants knowledge, together with mortality statistics for 236 jurisdictions collected by the United Nations between 1970 and 2021.
He discovered the numbers nearly mind-boggling.
The best numbers of centenarians are reported to incorporate Kenya, Malawi and the Autonomous Territory of Western Sahara, the place general life expectancy is simply 64, 65 and 71 years respectively.
An identical image is rising in Western nations, with the London borough of Tower Hamlets, one of the disadvantaged areas within the UK, reporting extra individuals aged over 105 than wherever else within the UK.
“I tracked 80 p.c of the world’s individuals over the age of 110, discovered the place they have been born and died, and analyzed population-level patterns,” Newman instructed Al Jazeera.
“It is completely surprising as a result of extra outdated age poverty means extra 110-year-olds.”

Newman argued that record-keeping errors, each intentional and unintentional, have been growing for many years, severely damaging the reliability of statistics associated to outdated age.
Some governments acknowledge critical shortcomings of their record-keeping associated to births and deaths.
In 2010, the Japanese authorities introduced that 82% of Japanese residents over the age of 100 have been reported lifeless.
In 2012, Greece introduced that it had discovered that 72% (about 9,000 individuals) of centenarians receiving pensions had died.
Puerto Rico’s authorities mentioned in 2010 that it could exchange all current delivery certificates over considerations about widespread fraud and id theft.
Newman mentioned extra prosaic causes may clarify the obvious longevity of residents in jurisdictions akin to Monaco, as low property taxes enchantment to older Europeans, skewing inhabitants knowledge.
Nonetheless, blue zone considering is tough to alter, even within the face of strong knowledge.
The meals and cultural customs of Okinawa Prefecture in Japan are sometimes praised by the media.
Nevertheless, based on the Japanese authorities’s annual Nationwide Well being and Diet Examination Survey, which has been carried out since 1946, Okinawans have among the worst well being indicators in Japan.
Whereas the normal Okinawan weight loss program is extensively thought-about wholesome, a 2020 research discovered that weight problems and demise charges amongst individuals aged 40-65 are actually increased in Okinawa than in mainland Japan.
Newman believes that the obvious longevity of Okinawans is the results of many unregistered deaths.
“It is nearly like we imagine so strongly that there is a secret to longevity that we’ll hearken to something — that the key to longevity is both going to the fitness center or not giving up alcohol,” Newman mentioned.
“We hope there’s some magic blueberry, and we actually hope it permits us to reside on this realm of potential cognitive dissonance.”
Newman says his analysis has not essentially received him pals in academia, though he has been happy with the assist from colleagues at College School London and the College of Oxford, the place he’s a researcher on the Institute of Inhabitants Growing old.
A lot of his work has obtained little consideration from fellow students, he mentioned, with one research he just lately submitted for publication receiving 9 peer evaluations as a substitute of the same old two or three.
Newman did get some notable recognition, although, and a legion of followers on-line, earlier this month when he was awarded the primary Ig Nobel Prize in Demography for his work.
The Ig Nobel Prize was established in 1991 as a satirical award to acknowledge “extraordinary analysis outcomes that make individuals chortle after which suppose.”
The prize is awarded yearly by an precise Nobel laureate at a ceremony at MIT.
“I am glad it is getting extra consideration as a result of I believe, I believe deep down, everybody additionally is aware of that this smoothie shouldn’t be going to avoid wasting them,” Newman mentioned.
“I believe it is a safety blanket that you just maintain on to, so subverting it in a hopefully fascinating approach, I believe that is going to get a variety of consideration and folks find it irresistible.”
Regardless of drawing consideration to pension fraud, Newman mentioned he was not accusing individuals of taking such steps.
“To be clear, I like individuals doing this as a result of they have been left behind by the governments in these locations. They are not getting sufficient pensions. They are not getting sufficient pensions,” he mentioned.
“The truth that they only mentioned, ‘Nicely, I will maintain accumulating Barry’s pension from the street.'” I believe that is indicative of the quantity of strain these individuals have been beneath.
