Have you ever wondered what sets the people living in “Blue Zones” apart from the rest of us? These are regions in the world with the highest concentration of centenarians – people who have lived to be over 100 years old. According to research by National Geographic and health experts, their longevity is not just a matter of luck or genetics. It’s a perfect combination of healthy eating habits, natural physical activity, and a positive mental attitude.
Diet: Food as Medicine
In Blue Zones such as Okinawa (Japan), Ikaria (Greece), and Nicoya (Costa Rica), food plays a central role in daily life. The locals prioritize plant-based diets, minimal meat consumption, and especially focus on fresh, seasonal produce.
As shared by Associate Professor Dr. Nguyen Thi Lam, Deputy Director of the National Institute of Nutrition of Vietnam, a diet rich in vegetables, fruits, and whole grains helps combat diseases and maintains long-term health. She emphasizes, “Fresh produce is not only more nutritious but also safer than processed food, which tends to be loaded with additives and artificial sweeteners.”
The Blue Zone residents also minimize their intake of salt, sugar, and processed foods. They typically eat only when hungry and stop short of feeling completely full, following the Japanese principle of ‘Hara Hachi Bu,’ which means eating until they are about 80% full. This practice aids digestion and prevents energy excess.
As it turns out, the secret to a long life may not lie in expensive or complicated dishes but in the mindful way we select and savor our meals.

Natural Movement: No Gym Required for a Healthy Life
In contrast to the hectic urban lifestyle, where people rush to the gym after work, Blue Zone inhabitants move naturally and continuously throughout the day. They engage in activities like gardening, walking, climbing hills, or simply tidying their homes. These gentle exercises offer substantial health benefits.
Dr. Pham Thi Ngoc Thao, Vice Director of Cho Ray Hospital in Ho Chi Minh City, affirms, “Regular physical activity, even something as simple as standing up and sitting down or walking around the house, improves blood circulation and boosts cardiovascular health.”
Interestingly, their living environments also encourage movement. The narrow lanes and car-free paths in Blue Zone villages promote walking and cycling. Even children develop a natural affinity for nature from an early age. So, if you’re looking to embark on a healthier journey, consider creating an environment that facilitates natural movement.

Positive Mental Attitude: Finding Joy in Simple Things
While diet and exercise are keys to physical health, a positive mental attitude forms the foundation for emotional well-being. Blue Zone residents excel at maintaining a positive outlook and reducing stress through meaningful relationships. They invest time in family, friends, and community and find happiness in simple pleasures like reading, singing, or participating in local festivals.
Dr. Tran Thi Minh Hanh, Director of the Ho Chi Minh City Nutrition Center, shares, “Chronic stress is a risk factor for numerous severe illnesses. Therefore, building healthy social connections and maintaining a cheerful disposition are vital for overall health.”
Additionally, elders in Blue Zones often have a sense of purpose, such as caring for grandchildren, engaging in religious activities, or contributing to their communities. This gives them a continued sense of value and involvement.
Remember, the secret to a long and happy life isn’t hidden; it’s in how we cherish ourselves and appreciate every moment.
