The surprising discovery behind the DNA of a 117-year-old woman: the food that could help you live longer

Telomeres and Protection Against Disease

Another aspect that fascinated researchers was the study of her telomeres, the structures that protect the ends of chromosomes. Normally, their shortening is associated with aging, but in María’s case, scientists observed a variation that may have protected her from serious illnesses, including certain types of cancer.

Dr. Esteller stated that extreme longevity is the result of “a combination of what we inherit and what we do with what we inherit.” In other words, it is a balanced mix of genetics and a healthy lifestyle.

Beyond the scientific findings, María also left behind a powerful message. After surviving COVID-19 at the age of 113, she became the oldest person to recover from the disease and used the media attention to share a reflection with the world: “This pandemic has shown that older people are the forgotten ones in our society. They have fought all their lives; they did not deserve to leave this world in this way.”

Wisdom, Humor, and a Full Life

Her social media biography described her with humor: “Very old, but not an idiot.” She lived in Catalonia surrounded by her family—three children, eleven grandchildren, and thirteen great-grandchildren—and shared advice on how to achieve a long and fulfilling life. Among her key recommendations were emotional calm, positivity, staying connected to nature, and above all, keeping distance from toxic people.

The story of María Branyas Morera not only inspires but also offers science a unique opportunity to better understand the secrets of human longevity. Her example shows that living longer depends not only on genes, but also on small daily habits, one’s attitude toward life, and perhaps on a simple yet powerful food: a yogurt at the start of the day.
