Boy this may change some recommendations about the “blue zone” diets and lifestyles.

https://en.wikipedia.org/wiki/Blue_Zone




I doubt that: https://en.wikipedia.org/wiki/Blue_Zone#Characteristics

Pretty standard, unanimous lifestyle advice. Stay social, stay active, not too much alcohol, lots of plants, avoid stress, don't smoke.


How much of those are based on erroneous correlations based on blue zone data though?

>In his book, Buettner provides a list of nine lessons, covering the lifestyle of blue zones people:[13]

>Moderate, regular physical activity.

>Life purpose.

>Stress reduction.

>Moderate caloric intake.

>Plant-based diet.

>Moderate alcohol intake, especially wine.

>Engagement in spirituality or religion.

>Engagement in family life.

>Engagement in social life.

We don't know which ones of those are real and which signify you live in a zone which has bad records for birth certificates.


Also what does "high vegetable intake" or "Plant-based diet" mean? These can mean wildly different things to different people.

For example, how many people over 100 are lifelong vegetarians? Vegans? I bet the number is extremely small (or zero in the case of vegans, a term coined in 1944), but that's what many people think of when one says "plant-based diet".


Plant based diet?

Well, that means lots of HFCS and starch, fried in vegetable oil, of course.


Meat-heavy diets are a recent phenomenon in most societies.


> We don't know which ones of those are real and which signify you live in a zone which has bad records for birth certificates.

While that is true, many of those things (regular physical activity, stress reduction, engagement in family/social life, moderate alcohol intake) improve your quality of life regardless of whether it makes you live longer.


Read the linked paper. Low literacy, low income, short life expectancy (!), high crime, in these zones have been ignored until now and are good predictors. It's more likely error/fraud than lifestyle.


FWIW Sardinia has one of the lowest crime rates in Italy. Thoae factors might be good predictors but the paper does not appear to quantify the effect.


Unless of course eating vegetables raises crime rates.


Did anyone investigate if these traits differed from other regions in japan, italy, costa rica and greece? In particular back in 2005?
