When Maria Branyas Morera passed away in August 2024 at 117 years old, she left behind more than a record—she provided a biological blueprint for longevity. Born in 1907 in San Francisco before settling in Catalonia, Spain, she lived through two world wars, the 1918 flu pandemic, and COVID-19. Now, a landmark study from the University of Barcelona has decoded the science behind her extraordinary life, revealing a powerful synergy between her genetics, her diet, and her gut microbiome.
The Science of Super-Aging
Led by geneticist Dr. Manel Esteller, the research team conducted what is considered the most comprehensive analysis ever performed on a supercentenarian. The findings were staggering. Morera’s biological cells were, on average, 17 years younger than her chronological age.
But the most dramatic revelation came from her gut. Her microbiome was dominated by Bifidobacteria—the same beneficial probiotics that flourish in the digestive tract of a healthy newborn. This created a potent anti-inflammatory state that scientists believe protected her from the chronic diseases that typically accompany aging.
“She had no cardiovascular problems. Her mind was completely clear,” Dr. Esteller noted. “She could recall memories from when she was four years old. Her only limitations were minor mobility and hearing issues—incredible for someone her age.”
The Three-Cup Secret
How did she cultivate such a robust internal ecosystem? The answer lies in a remarkably simple dietary habit.
Morera adhered strictly to the Mediterranean diet, but one element stood out: she consumed three cups of natural yogurt every single day. This fermented staple is rich in the same probiotics that populated her youthful gut microbiome, helping suppress inflammation and maintain digestive health throughout her 117 years.
Her diet followed a clear, consistent pattern:
- Daily yogurt providing live probiotics to support gut flora
- Abundant fruits and vegetables for fiber and antioxidants
- Olive oil and fish delivering anti-inflammatory omega-3 fatty acids
- No alcohol or tobacco eliminating major inflammatory triggers
Lifestyle Beyond the Plate
Diet alone didn’t get her to 117. Morera’s daily habits reinforced the biological advantages of her eating style. She walked regularly, stayed close to nature, maintained strong social bonds, and deliberately avoided toxic relationships and stress.
This combination is critical. Research increasingly shows that gut health doesn’t exist in a vacuum—it responds to exercise, sleep, and emotional well-being. Her lifestyle perpetuated the anti-inflammatory environment her diet created.
Applying the Blueprint
For those of us in Hong Kong’s fast-paced food culture, Morera’s habits are surprisingly accessible. The implications go beyond living longer; they point toward living better.
Start with one small change: introduce a daily serving of fermented foods—yogurt, kefir, or even kimchi. Pair it with a shift toward whole, plant-based ingredients and healthy fats. The science suggests that consistent, small habits, layered over time, can systematically lower chronic inflammation and reshape your gut microbiome for the better.
The message from Maria Branyas Morera’s life is clear. Longevity isn’t found in a single superfood or a drastic intervention. It is cultivated quietly, daily, through the food we eat and the lives we build around it.
