Major revelation about 'blue zones' where many live to 100 could change everything we know about them

A new study on 'blue zones' could cast doubt on how people perceive the 'life-expanding' locations.

There are currently five reported blue zones spread around the planet, these are: Loma Linda in California, Nicoya peninsula in Costa Rica, Okinawa in Japan as well as the islands of Sardinia and Icaria in Italy and Greece respectively.

So what is a blue zone? Well, it's a place where people typically live much longer than the average person.

For example, back in 2012, the tiny town of Perdasdefogu in Sardinia, Italy was given a Guinness World Record for the largest concentration of centenarians (people over 100), with eight people in triple digits in a population of 1,778 in June 2021.

It is also home to the Melis family, who won the Guinness World Record for the highest combined age of nine living siblings, with a combined age of 818 years in 2012.

However, some new research could change the way we see blue zones, after Dr Saul Justin Newman won an Ig Nobel award for his work in uncovering the flaws in data about the world's oldest people and the alleged blue zones.

Dr Newman revealed that while some of the citizens in these locations are thought to be alive in government records, they had actually passed away in real life.

University College London explained: "Dr Newman debunked the popular idea of ‘blue zones’ as regions of exceptional longevity and healthy lifestyles. Many, if not most of the centenarians in the ‘blue zone’ have turned out to be alive in the government records but were deceased in reality.

"Using extensive government data and surveys, Dr Newman showed that most of the dietary and lifestyle claims behind the so-called ‘blue zone’ regions of high longevity are not supported by any independent data.

"For example, despite vegetables and sweet potatoes being promoted as key components of the Okinawan ‘blue zone’ diets, according to the Japanese government, Okinawans eat the least vegetables and sweet potatoes in Japan and have the highest body mass index."

Longevity researcher, Dan Buettner's 2023 Netflix documentary Live to 100: Secrets of the Blue Zones, explored some of the factors that are believed to make the 'blue zones' so special.

"The key factor across all the blue zones is that the centenarians living there did not wake up one morning and decide they wanted to live to 100," Buettner explained in a previous interview with The National.

"They simply lived in environments that nudged them into daily movement, encouraged social connectedness and plant-based eating – making the healthy choice not only easy, but unavoidable."

For example, Buettner explained that in Sardinia, the Melis family had the same meal every day.

Buettner said: "Every day of their life they had the same meal for their lunch.

"A sourdough bread, a three bean minestrone soup - a chunky minestrone with garden vegetables.

"It always had three beans; a garbanzo, a pinto and a white bean.

"And then they had a small glass of red wine. I'm talking a two to three-ounce glass.

"Now this wasn't because 'my diet requires me to do it'.

"No, they loved it."
