Journalist and researcher Dan Buettner, with support from National Geographic, spent years studying the world's five longest-living communities — Sardinia, Okinawa, Nicoya, Ikaria, and Loma Linda. These communities live on different continents, practice different religions, and eat different cuisines — they share no common genetics. Yet their ways of life show a striking overlap: Buettner distilled these commonalities into nine points and called them "Power 9."
The most important thing about Power 9 is this: none of it says "go to the gym" or "follow a special diet." Every principle is ordinary enough to be a natural part of daily life — which is exactly what makes it sustainable.
Natural movement (shepherding) · Moderate alcohol (Cannonau) · Loved ones first
Purpose (ikigai) · The 80% rule · Right tribe (moai)
Purpose (plan de vida) · Plant-slant diet · Natural movement
Downshift (midday nap) · Plant-slant diet
Spirituality/belonging (weekly worship) · Plant-slant diet (mostly vegetarian) — the one exception: no alcohol
In 2024, UCL demographer Saul Newman, in a study that won an Ig Nobel Prize, argued that some Blue Zone supercentenarian (100+ and especially 110+) statistics may stem from missing birth certificates, record-keeping errors and even pension fraud. His claim: the highest rates of "extreme old age" correlated with low birth-certificate registration rates and high poverty.
Power 9 creator Dan Buettner and his team pushed back hard; in a 2025 paper published in The Gerontologist, they said the data had been independently verified through church records, and birth/marriage/military/death registers. One interesting detail: that verification paper doesn't cover Loma Linda, the most disputed of the five regions — Buettner later acknowledged Loma Linda was added to the list because "the National Geographic editor wanted a region from the Americas."
As Vivelong, we want to state this transparently: the debate is centered mainly on the statistic of "how many people really lived past 100" — it doesn't debunk the health benefits of the individual Power 9 behaviors (plant-slant eating, regular movement, social connection, sense of purpose), which are supported separately by a much broader body of epidemiological literature (e.g. the Harvard Study of Adult Development), independent of the Blue Zones controversy. But the claim that "an incredible number of people over 100 live in these 5 villages" shouldn't be repeated as uncritically as it once was.
Yes. In 2024, demographer Saul Newman won an Ig Nobel Prize for arguing that some supercentenarian statistics may stem from record-keeping errors and missing birth certificates. Dan Buettner and his team formally rebutted this in a 2025 paper in The Gerontologist, citing official records — but that paper doesn't cover Loma Linda, the most disputed region. The debate is confined to "how many people really lived past 100"; the health benefits of the Power 9 behavioral recommendations are supported by separate literature.
Power 9 emerged not from a single study but as the common thread across dozens of demographic and epidemiological studies in the five Blue Zones — so we're talking about strong correlation, not proven causation. A sense of purpose has been linked to up to 7 additional years, and regular attendance at services to 4–14 additional years, of life expectancy. These are observational findings — no "exact X years longer" guarantee — but a strong signal where millennia of community experience meet modern epidemiology.
There isn't a single "most effective" principle — Power 9's strength comes from all nine working together, woven into daily life. The two that stand out most: Purpose (linked to up to 7 additional years of life expectancy) and Social Connection (lets healthy behaviors spread "contagiously" through your circle). Vivelong's advice: start with the 1-2 principles that feel easiest, rather than trying to change everything at once.
The "Moderate Alcohol" principle applies in 4 of the 5 regions — Loma Linda's Seventh-day Adventists are the exception, since their faith prohibits alcohol. This shows Power 9 isn't one rigid formula: the nine principles manifest differently region to region. In Loma Linda, a stronger sense of spirituality and community fills that role instead — same outcome (a regular, community-based downshifting ritual), different vehicle.
"Longevity isn't a sprint. Blue Zone residents aren't chasing a long life — they're simply living in the right environment with the right habits, and the outcome follows on its own."
