Scientists studying the DNA and lifestyle of Maria Branyas Morera, who lived to be 117, believe they may have uncovered key factors in longevity.

Maria, who held the title of the world’s oldest person until her passing in August 2024, had a remarkably healthy microbiome and a “privileged genome,” according to researchers at Barcelona University.

The Secrets Behind Maria’s Longevity

Genetics professor Manel Esteller found that Maria’s unique genes made her biological age about 17 years younger than her actual age.

Her daughter, Rosa Moret, noted that Maria was rarely ever ill, which likely contributed to her long life. Although she began experiencing declines in eyesight, memory, and hearing towards the end, she maintained exceptional cholesterol levels, blood sugar regulation, and a well-balanced immune system.

Her diet played a crucial role—she followed a Mediterranean diet, ate three yogurts daily, avoided alcohol and smoking, and prioritized staying active by walking regularly. Most importantly, she surrounded herself with loved ones, a factor researchers believe contributed significantly to her well-being.

The findings challenge the common belief that aging must be linked to illness. Researchers hope to use insights from Maria’s lifestyle and genetics to develop anti-aging medicines and explore dietary recommendations for longevity.

Maria was born in San Francisco in 1907 to Spanish and Mexican parents, but her family returned to Spain in 1915 during World War I. Following her passing, the title of the world’s oldest person now belongs to Inah Canabarro Lucas, a Brazilian nun born in 1908.
