How a simple habit shaped a remarkable life
Maria Morera Branyas, known to scientists as M116, lived to 117 years and 168 days. Her longevity attracted scientific attention, not because of a single “super gene,” but because of a quiet daily routine and a uniquely balanced biology. A key thread in her story was a humble habit: eating yoghurt three times a day. Far from a trend, this practice formed part of a lifestyle that researchers say helped keep her gut healthy, inflammation low, and metabolism stable well into advanced age.
The gut as a central player in aging
Researchers from the Josep Carreras Leukaemia Research Institute found that Maria’s gut microbiome resembled that of someone decades younger. Her gut was rich in Bifidobacterium, a beneficial bacterium associated with reduced inflammation and better metabolism. Yogurt containing probiotic strains such as Streptococcus thermophilus and Lactobacillus bulgaricus supported this microbial balance, which may have contributed to her long, healthy life.
What the science says about Yogurt and longevity
In a 2024 report in Cell Reports Medicine, scientists proposed that Maria’s consistent intake of probiotic-rich yogurt could help maintain a youthful gut environment. A robust gut microbiome can influence metabolism, immune function, and even brain health—factors closely tied to healthy aging. Maria’s case stands out not only for her age but for how her gut health defied common age-related patterns, where microbial diversity often declines with advancing years.
Genetic and lifestyle factors complementing gut health
Beyond the yogurt habit, Maria’s biology and daily routines contributed to her longevity. She carried genetic variants associated with strong immune function, brain health, and cardiovascular protection, while lacking several variants known to shorten lifespan. Her lipid profile—high HDL cholesterol with low triglycerides—helped sustain heart health. Yet, even with unusually short telomeres, she showed few major illnesses, underscoring that aging and disease aren’t fixed by genetics alone.
A lifestyle of balance, activity, and calm
Maria’s life was marked by a Mediterranean diet, regular physical activity, and emotional equilibrium. She abstained from smoking and alcohol, enjoyed olive oil and whole foods, and took daily walks. Even later in life, she stayed mentally engaged by listening to music, socializing, and remaining curious. Researchers suggest these habits likely dampened chronic inflammation and kept her immune system responsive, further supporting her exceptional health span.
What her story means for today’s pursuit of healthy aging
Maria Morera’s case is not a prescription for chasing 117, but a reminder that longevity can hinge on the health of the gut and a steady, nourishing lifestyle. Experts like Prof. Claire Steves emphasize that her longevity appears to result from multiple interconnected systems—gut health, immune function, metabolism, and genetics—working together.
Conclusion: small acts, big impacts
Her daily yogurt might seem modest, but it symbolizes a broader truth: consistent, healthful habits can shape how we age from the inside out. Maria’s life suggests that the secret to a long, good life may begin in the gut and flourish through kindness, routine, and balanced living.
