World's Oldest Woman's DNA and Diet May Explain Her 117 Years

Study finds Maria Branyas Morera’s longevity linked to protective genes, low inflammation, and a healthy gut microbiome, with biological age 23 years younger than chronological age.

  • Maria Branyas Morera passed away in 2024 at 117 years old and contributed samples of her gut microbiome for scientific research.
  • She had agreed to participate in research investigating how genetics, diet, and biology contributed to her longevity.
  • Researchers observed that her gut microbiome exhibited a level of diversity comparable to that of much younger individuals and contained a high abundance of helpful bacteria associated with health, longevity, and resilience.
  • Branyas followed a Mediterranean diet and ate three yogurts daily, each containing live bacteria supporting beneficial gut microbes like Bifidobacterium.
  • Scientists inferred that her remarkably youthful microbiome likely played a role in maintaining her digestive and immune system functions, while emphasizing that her extended lifespan results from a combination of various factors beyond the microbiome alone.
