In the pursuit of a longer, healthier life, the world has shifted its focus from seeking mythical immortality-granting items to adopting healthier habits and nutritious diets. With the rise in the number of centenarians globally, the question arises: What is the secret to their longevity?
The Power of Blue Zones
National Geographic Fellow Dan Buettner and his team conducted a study in 2016, identifying five areas in the world where people consistently live over a century. These areas, known as the "Blue Zones," include Sardinia (Italy), Ikaria (Greece), Nicoya (Costa Rica), Loma Linda (California), and Okinawa (Japan).
In these regions, Buettner discovered nine common practices, dubbed the "Power 9," that could potentially slow down the aging process. These practices include:
- Natural movement
- Having a purpose in life
- Stress reduction
- Practicing the 80% diet rule (stop eating when 80% full)
- Favoring a plant-based diet
- Moderate alcohol consumption
- Belonging to a community
- Prioritizing family
- Maintaining a social circle that supports healthy behaviors
Interestingly, loneliness is a top risk factor for a shorter life. Thus, preventing it could add years to our lives.
Emphasizing the Role of Diet in Longevity
The "Blue Zones" study has led to the formulation of the Blue Zone Food Guidelines, reflecting the dietary habits of the world's longest-living people. Buettner collaborated with Harvard for his book, The Blue Zones Kitchen, collecting 155 dietary studies done in all Blue Zones over the past 80 years.
The pillars of every longevity diet in the world include whole grains, nuts, greens, other garden vegetables, tubers, and beans. It's vital to note that over 90% of their traditional dietary intake came from whole food, plant-based sources.
Additionally, The Longevity Diet, developed by Dr. Valter Longo, Edna M. Jones Chair in Gerontology and professor of gerontology and biological sciences at the USC Leonard Davis School of Gerontology, emphasizes the importance of dietary habits in increasing longevity and healthspan.
The main aspects of the Longevity Diet include eating a low-protein pescatarian diet until the age of 65–70 years, followed by moderate proteins later in life, fasting for 12 hours every night, and doing, on average, three cycles of a fasting-mimicking diet per year, each lasting 5 days.
Impact of Lifestyle Factors on Lifespan
A comprehensive study of over 700,000 US veterans revealed eight lifestyle habits that could significantly extend life expectancy. These habits include:
- Regular physical activity
- Freedom from opioid addiction
- Non-smoking
- Stress management
- Good diet
- Minimal binge drinking
- Good sleep hygiene
- Positive social relationships
These lifestyle factors play a crucial role in reducing chronic diseases and highlight that adopting healthier habits, even later in life, can still contribute to longevity.
The Role of Social Connections and Positive Thinking
Research shows that having a sense of meaning or purpose in daily life is associated with better sleep, healthier weight, higher physical activity levels, and lower inflammation in some people. Moreover, a study found that being optimistic was associated with a person living 11-15% longer and having a stronger likelihood of living to age 85 or older.
Moreover, social connections play a crucial role in longevity. Studies of adults 50 years and older show that loneliness and social isolation are associated with a higher risk of disease, disability, and mortality.
Importance of Regular Exercise and Maintaining a Healthy Weight
Regular physical activity lowers the risk of several chronic conditions that increase with age, including heart disease, hypertension, diabetes, osteoporosis, certain cancers, and cognitive decline. Exercise also helps to lower anxiety and blood pressure, and improve sleep quality.
On the other hand, keeping a healthy weight is also important for longevity. A high body mass index (BMI) was associated with substantially shorter healthy and chronic disease-free life expectancy.
The Influence of Social Determinants on Health
Social determinants of health, such as education level, racial segregation, poverty, low social support, and income inequality, play a significant role in determining health outcomes. Strategic investments in education, reducing poverty and income equality, and improving social relations might yield considerably greater returns than continuing to escalate investments in medical care.
The Japanese Approach to Longevity
Japanese women and men currently live five to six years longer than Americans. In Japanese families, elders are highly revered and households are intergenerational. Japanese elders are generally healthier than their Western counterparts, and they maintain a control over their weight. They consume smaller portions, more fermented foods, less sweets, and less red meat.
Final Thoughts
The quest for longevity isn't merely about extending one's lifespan but about enhancing the quality of life. The secret to longevity is not a one-size-fits-all formula but a combination of various healthy lifestyle habits. Adopting these practices can transform your healthspan and how you age in the future. It's never too late to start living a healthier life.
