Remarkable Find Sparks Secrets Behind Woman’s Extraordinary 117-Year Longevity

Scientists have discovered insights into the longevity of Maria Branyas Morera, who lived to be 117 years old. A study by researchers at the University of Barcelona revealed that Branyas had a unique gut microbiome resembling that of an infant, which, along with her genetics and healthy lifestyle, contributed to her long life. The findings were reported in March 2025.

Maria Branyas Morera, born in 1907 in the U.S. and raised in Catalonia, Spain, was recognized by Guinness World Records as the oldest living woman in January 2023. Throughout her life, she worked as a nurse and maintained a healthy lifestyle, avoiding alcohol and smoking. She enjoyed a Mediterranean diet and was active in her community, having three children and numerous grandchildren.

Branyas’ exceptional genetics also played a role in her longevity. Researchers estimated that her cellular age was 17 years younger than her actual age. The study highlighted several key factors contributing to her long life:

• Unique gut microbiome similar to that of infants.
• Healthy lifestyle choices, including regular walking and a balanced diet.
• Strong family connections and social engagement.

Despite living through significant historical events, including two World Wars and two pandemics, Branyas experienced minimal health issues and maintained her cognitive abilities until her passing in August 2024. The researchers hope that understanding her longevity can lead to health insights that benefit others.

The research into Maria Branyas Morera’s life underscores the complex interplay of genetics, lifestyle, and microbiome health in determining longevity. As scientists continue to explore these connections, they aim to uncover valuable lessons that could enhance health for people worldwide.
