Unlocking the “Blue Zones” with Dan Buettner: Tracing the Lifestyles of Centenarians Around the World, Highlighting Simple, Actionable Tips
Dan Buettner, a National Geographic explorer and discoverer of the “Blue Zones” – areas with the world’s highest concentrations of centenarians – has revealed the secrets to a long and healthy life. In a special lecture in Thailand, he emphasized that the key isn’t genetics, advanced medicine, or intense exercise, but rather a simple lifestyle that can be realistically adopted.
The Genesis of the Blue Zones Discovery
Buettner recounted the starting point of his journey to uncover the secrets of longevity. It began with reading a World Health Organization (WHO) report indicating that a cluster of islands in Southeast Asia had 30 times more women reaching the age of 100 than in the United States. That place was Okinawa, Japan.
“I asked myself, how did they do this? Do they have special genes or some other advantage?” Buettner said. “But when I studied it deeply, I found that they have average genes, a melting pot of people from all over Southeast Asia, China, and even Thailand.”
Buettner explained that genetics only account for 15% of life expectancy. The quality of doctors and the healthcare system accounts for another 15%. The remaining 70% is other non-genetic factors, which is what he focused on.
Finding Blue Zones Around the World
In collaboration with demographers, Buettner surveyed and identified other areas around the world with long-lived populations:
- Okinawa, Japan: Women have the longest lifespans in the world.
- Sardinia, Italy: A cluster of mountain villages where men have the longest lifespans in the world.
- Nicoya, Costa Rica: A population that lives long lives without disease.
- Ikaria, Greece: A population that lives about 8 years longer than Americans.
- Loma Linda, California, USA: A group of Seventh-day Adventists with long lifespans.
Common Factors of People in Blue Zones
Buettner found that the common factors contributing to the longevity and well-being of people in the Blue Zones are not about gym workouts, pharmaceuticals, or cutting-edge technology, but a simple lifestyle as follows:
-
Diet:
- Eat a primarily whole plant-based diet, including whole grains, leafy greens, tubers, and nuts.
- Eat about 1 cup of beans per day, including soybeans and tofu.
- Consume meat and sweets in small quantities and only on special occasions.
- Eat meals with family to reduce stress and eat more slowly.
- Eat meals within an 8-10 hour window each day to allow the digestive system to rest.
-
Physical Activity:
- No one in the Blue Zones exercises in a gym, but they are physically active all the time.
- Walk 8,000-10,000 steps per day without consciously trying.
- Do housework, gardening, and grow their own vegetables.
-
Social Connections:
- Live in extended families, where older adults play a role in raising children and have value in the family.
- Have strong community ties, participating in religious activities and festivals.
- Have close friends they can rely on in times of need.
-
Purpose in Life:
- Have “Ikigai,” or a reason for waking up in the morning.
- Have goals and responsibilities to family, community, and faith.
- Having a purpose in life helps people live about 7 years longer.
Recommendations for Thailand
Buettner pointed out that Thailand has the potential to become a “Blue Zone,” but it requires a major shift. He emphasized focusing on changing the environment and ecosystem to allow people to make healthier decisions unconsciously.
“There are no shortcuts to longevity. There are no supplements, drugs, or exercise programs that will affect whether you are alive and thriving in 2040,” Buettner said. “The important thing is to do things that you can do every day for decades.”
Buettner cited Singapore, which he calls a “New Blue Zone,” as an example of policy changes:
- High taxes on cars and gasoline to encourage the use of public transportation and walking.
- Reduced sugar content in beverages.
- Warning images on cigarette packs and high taxes on tobacco.
Applying Blue Zones Principles at the City and Organizational Levels
Buettner has a company that works with cities in the United States to change policies to favor healthy choices, such as certifying restaurants, grocery stores, workplaces, and churches that promote healthy eating and physical activity.
He also recommended that corporate executives change policies and the work environment to encourage employees to be more physically active, have easier access to healthy food, have good relationships with each other, and have opportunities to pursue their life goals.
The Aging Society: Opportunities and Challenges
Buettner addressed the issue of Thailand’s aging society by saying that instead of worrying about the economic burden, the focus should be on older people as valuable resources, both economically and in terms of wisdom, childcare, and contributing to societal happiness.
AI and Technology: Can They Really Extend Life?
Buettner believes that AI may play a role in developing drugs or genetic therapies to slow aging, but it cannot replace the Blue Zones lifestyle, which involves living happily, close to nature, eating healthy food, having good relationships, and having a purpose in life.
Dan Buettner’s Personal Tips
Buettner shared his personal tips for living a Blue Zones lifestyle:
- Wake up when the body is ready, without using an alarm clock.
- Live in a walkable neighborhood, near the sea.
- Eat the first meal at 11 a.m., a vegetable and bean soup.
- Work 4-5 hours a day.
- Spend 3 hours a day socializing.
- Take a nap.
- Engage in enjoyable physical activities every day, such as swimming, cycling, yoga, weight training, or playing pickleball.
Living a long and healthy life is not a matter of fate or advanced technology. It’s about a simple lifestyle that can be realistically adopted, focusing on eating a plant-based diet, regular physical activity, strong social connections, and having a purpose in life.
