Maria Branyas lived to be the world’s oldest woman at an astonishing 117 years old.
Spanish scientists have now examined everything from her genes to her gut bacteria to unlock the secrets behind her extraordinary longevity – and one everyday food might have played a surprising role.
Her Gut Looked Decades Younger
Maria’s gut microbiome resembled that of a much younger person, full of microbial diversity. Scientists believe this youthful gut environment helped her body age more slowly.
Yogurt Was a Daily Staple
She had a strong preference for yogurt, a fermented food known to support gut health. Researchers suspect this played a role in nurturing her beneficial gut bacteria.

She Stayed Mentally and Physically Active
Even into old age, Maria remained engaged with the world around her. Activity—both mental and physical—is known to delay cognitive decline and promote overall health.
She Followed a Mediterranean Diet
Maria’s meals were filled with vegetables, legumes, fish, olive oil, and whole grains—hallmarks of the Mediterranean diet, which has long been linked to longevity.
Her Genes Were Built for Resilience
Researchers found that Maria had protective genes associated with lower risks of heart disease and cancer. Her genetic blueprint may have been one of her greatest assets.
She Had a Much Lower Biological Age
Despite being 117 chronologically, tests of her tissue showed a biological age far younger, indicating slower aging at a cellular level.

Chronic Inflammation Stayed Low
Unlike many elderly individuals, Maria maintained low levels of chronic inflammation, which is linked to many age-related illnesses.
Her Gut Produced Powerful Compounds
Her gut microbes generated a specific set of metabolites that impact everything from brain function to immune response, possibly protecting her health.
Gene Regulation Was Remarkably Balanced
The way her body turned genes on and off—known as DNA methylation—functioned optimally, which may have helped preserve her health.
Strong Social Ties May Have Added Years
Maria lived a socially connected life, something research consistently ties to better mental health and increased longevity.
