Former Taiwan Minister of Health and Welfare and current Co-CEO of AHMC Health System, Dr. Wen-Ta Chiu, has published Everyday Health Revolution, blending personal evidence-based practice with lifestyle medicine to present a practical blueprint for everyday health.
Starting this week, Cultural Weekly launches a seven-part health column featuring the book’s core insights. The opening installment—Blue Zones—draws on the world’s longest-living communities to mark the starting point of this health revolution.

Blue Zones Revealed — A Global Map of Longevity
If there truly are places in the world where people tend to live longer and age in better health, what would those places look like?
This was the question National Geographic Magazine took seriously—and answered with a map.
It was not a map highlighting the most advanced medical centers or the wealthiest regions.
Instead, it circled a handful of ordinary, sometimes remote islands and communities. These places would later be known as the Blue Zones.
The name itself is straightforward. In the late 20th century, demographers studying longevity in Sardinia, Italy discovered an unusually high concentration of centenarians in certain mountain villages.
They marked these areas on their maps with blue ink.That small blue circle soon caught the attention of National Geographic’s research team.
National Geographic fellow and author Dan Buettner took it as a starting point, launching years of fieldwork and cross-national research to understand what these long-lived populations were doing differently.
In 2005, National Geographic introduced the concept to a global audience with its cover story on longevity, opening a new chapter in public-health research and discussions on healthy aging.
Today, five regions are widely recognized as Blue Zones : Okinawa, Japan; Sardinia, Italy; Ikaria, Greece; the Nicoya Peninsula, Costa Rica; and Loma Linda, California, USA.
Though vastly different in culture, religion, and living conditions, they share strikingly similar patterns of long and healthy lives.
Okinawa, Japan - Everyday Wisdom from the Island of Longevity
Okinawa has long been known as an island of longevity, particularly for its exceptionally long-lived women.
In local communities, older adults remain active and engaged in daily life.
Diet is a defining feature. Traditional Okinawan meals center on sweet potatoes, tofu, vegetables, seaweed, and turmeric, with minimal oils and processed foods.
A lifelong principle—hara hachi bu—means eating until one is about 80 percent full.
Equally important is how people live. Okinawa’s moai culture forms lifelong mutual-support groups, where friends meet regularly and care for one another from youth through old age.
These strong social bonds ensure that aging does not mean isolation, offering powerful support for mental well-being.
Sardinia, Italy — Mountain Life and Male Longevity
Sardinia stands out for its unusually high number of male centenarians.
Many spent their lives herding livestock or farming, maintaining high levels of physical activity without formal exercise routines.
Their diet follows a traditional Mediterranean pattern—whole grains, legumes, vegetables, olive oil, modest amounts of sheep’s milk products, and local red wine.
Multigenerational households and daily family meals provide emotional security and reduce chronic stress, reinforcing both physical and mental health.
Nicoya Peninsula, Costa Rica — Knowing Why You Live
In Nicoya, longevity is matched by a strong sense of vitality. Locals often speak of plan de vida—a clear reason for getting up each day.
Staple foods include corn, beans, and squash, complemented by clean water and strong community ties. Aging here is not a retreat from life, but a continued participation in family and society.
Ikaria, Greece — The Longevity of Slowing Down
Often called “the island where people forget to die,” Ikaria moves at an unhurried pace. Residents follow a Mediterranean diet, drink local herbal teas, nap regularly, and prioritize long social gatherings.
Efficiency is not the goal. Presence is. Daily physical activity comes naturally through farming and household tasks, making movement a seamless part of life.
Loma Linda, California, USA — Longevity in the Modern World
Loma Linda is the only Blue Zone located in a highly industrialized society. Home to many Seventh-day Adventists, the community centers on health, moderation, and faith.
Plant-based diets, no smoking or alcohol, regular exercise, and a weekly Sabbath dedicated to rest and social connection form the backbone of daily life - an intentional rhythm that protects health amid modern pressures.
Why Blue Zones Matter
Viewed together, Blue Zones are not the result of superior genetics or advanced medical technology.
They are the product of long-term lifestyle patterns-natural diets, integrated movement, strong social bonds, reduced stress, and a clear sense of purpose.
These elements align closely with the principles of Lifestyle Medicine, which emphasizes that chronic disease prevention and healthy aging depend not primarily on medication, but on how we live.
Blue Zones are not laboratory experiments. They are real-world proof that longevity is learnable, practical, and achievable—one daily choice at a time.
