An analysis of the DNA of María Branyas Morera, who lived to the age of 117, has revealed fascinating clues about the factors that may influence a long and healthy life. Her story, shaped by more than a century of experiences, has sparked enormous interest within the scientific community.
A Life That Spanned More Than a Century
María Branyas Morera was born on March 4, 1907, in the United States, at a time when the world had yet to imagine many of the technological advances we now take for granted. Her life was a true journey through history: she lived through two world wars, the COVID-19 pandemic, and witnessed the rise of the digital age. After moving with her family to Catalonia in 1915, María developed a deep connection with nature and the Mediterranean lifestyle—factors that may have played a key role in her longevity.
Before her death in 2024, she made a very specific request: that a team of Spanish scientists be allowed to analyze her biological and genetic profile to understand the reasons behind her exceptional health. Researchers from the University of Barcelona and the Josep Carreras Leukemia Research Institute took part in the study, collecting tissue samples and examining the genetic makeup of the supercentenarian.
Separating Aging From Disease
Dr. Manel Esteller, the lead researcher on the project, explained in an interview that María’s case was unique. “The general rule is that as we age, we get sicker, but she was an exception, and we wanted to understand why,” he said. According to the researcher, the findings made it possible to “separate aging from disease,” something that until now had seemed impossible.
The Yogurt Habit That Caught Scientists’ Attention
The analyses showed that María’s biology was equivalent to that of someone 10 to 15 years younger than her actual age. She had low levels of bad cholesterol and triglycerides, along with high levels of good cholesterol, which surprised specialists. In addition, she maintained strong cardiovascular health, a sharp mind, and an energy level that defied expectations.
