Maria Branyas Morera, the world’s oldest verified living person until her passing in 2024, reached the astonishing age of 117. But what made her body defy time? Scientists believe they’ve uncovered some fascinating clues.
A recent study led by researchers at the Josep Carreras Leukaemia Research Institute and published in Cell Reports Medicine revealed that Maria’s biological age was significantly younger than her chronological age. DNA methylation tests showed her cells behaving as if she were 94—not 117.
🥣 The Yogurt Connection
One of the most surprising findings was Maria’s daily habit of eating yogurt. Her gut microbiome contained unusually high levels of Bifidobacterium, a beneficial bacteria more commonly found in younger individuals. This may have contributed to her low inflammation markers and overall metabolic health.
🧬 Genetic Luck and Cellular Efficiency
Maria’s blood analysis revealed:
- Very low triglycerides
- High HDL cholesterol
- Efficient fat metabolism
- Rare protective gene variants
- Energetically active mitochondria
These traits are linked to reduced risk of heart disease, cancer, and neurodegeneration.
🧠Lessons for Longevity
While lifestyle played a role, Maria’s case also highlights the importance of genetics and cellular resilience. Researchers hope her unique biology can help identify biomarkers for healthy aging and inspire new strategies to extend human lifespan.
