Unlocking the Secrets of Longevity: The Case of Maria Branyas
When Maria Branyas, a Catalonian woman, passed away in August 2024 at the age of 117 years and 168 days, she held the title of the world’s oldest living person. Her remarkable journey to becoming a supercentenarian intrigued researchers from the Josep Carreras Leukemia Research Institute in Spain, who delved deep into her biology to uncover the secrets behind her extraordinary lifespan.
The study, which is currently awaiting peer review, offers valuable insights into the cellular mechanisms that may hold the key to reaching a second century of life. Maria’s story serves as a beacon of hope for those seeking to understand the intricacies of healthy aging.

The researchers found that Maria’s lifestyle played a significant role in her longevity. She maintained mental, social, and physical activity, engaged in meaningful relationships with loved ones, and followed a Mediterranean-style diet, all of which are associated with healthy aging.

One interesting observation was Maria’s fondness for yogurt, which researchers believe contributed to a healthy gut microbiome. Her gut flora resembled that of a much younger individual, highlighting the importance of diet in maintaining overall health.
Genetic analysis revealed that Maria possessed genes linked to a robust immune system, reduced risk of heart disease, and protection against cancer. Additionally, assessments of DNA methylation indicated a biological age significantly younger than her chronological age, indicating resilience to environmental stressors.
Furthermore, Maria exhibited efficient metabolism, optimal cholesterol levels, and low inflammation, factors that safeguard against age-related ailments. Her commitment to a structured life and nurturing environment undoubtedly played a role in her exceptional health and longevity.
The researchers’ findings underscore the notion that advanced age and poor health are not synonymous, emphasizing the potential for healthy aging at a molecular level. While most may not reach Maria’s remarkable age, the study offers valuable insights into promoting longevity and well-being in old age.
The research, available on the preprint server BioRxiv, sheds light on the complex interplay of genetics, lifestyle, and biology in shaping the trajectory of aging.
