Many centenarians credit their plant-heavy diets as a cornerstone of their longevity. In regions like Sardinia and Ikaria, meals are built around vegetables, whole grains, and beans, with meat enjoyed only occasionally. This approach, reflected in Mediterranean and Okinawan traditions, is associated with lower rates of chronic diseases and greater life expectancy. As noted by National Geographic, the focus on beans, leafy greens, and simple, unprocessed foods is a signature of the world’s healthiest elders.

2. Regular Physical Activity

The world’s oldest people rarely spend hours at the gym. Instead, they weave natural movement into their daily routines—walking to visit neighbors, tending gardens, or doing household chores. In Okinawa, gentle exercise is a lifelong habit, while Sardinians navigate steep paths as part of everyday life. It’s not about intensity, but consistency. According to Harvard Health, this regular, low-impact activity is strongly linked to greater longevity.

3. Strong Social Connections

Deep, supportive relationships are a hallmark of longevity around the world. In Blue Zones, people nurture connections—whether through multigenerational households or tight-knit circles like Okinawa’s moais, which provide lasting companionship and practical help. Social bonds are more than just pleasant—they’re protective. Research from the Mayo Clinic shows that robust social support helps buffer stress and contributes to both mental and physical well-being.

A clear sense of purpose runs through the lives of the world’s oldest people. In Japan, this is called ikigai; in Costa Rica, plan de vida. This guiding reason to wake up each morning—whether it’s family, work, or community—has been linked to lower mortality rates and higher satisfaction.
According to the NIH, purposeful living supports both emotional and physical longevity.

Centenarians often incorporate simple stress-busting rituals into their days—whether it’s daily meditation, prayer, or a restorative afternoon nap. These habits aren’t just soothing; they help reduce inflammation and the risk of chronic disease. According to the American Psychological Association, consistent stress management is a key factor in maintaining long-term health and resilience.

In the world’s longest-living communities, meals are built around fresh, minimally processed ingredients.

Long-lived populations commonly enjoy healthy fats from sources like olive oil, nuts, and fish. These fats, staples of Mediterranean and Nicoyan diets, are known to support both heart and brain function.
