World’s Oldest Woman Lived to 117 With Infant-Like Gut Microbiome: The Secret Was Bifidobacterium
A new study reveals how Maria Branyas Morera, the world’s oldest woman who lived to 117, maintained a gut microbiome similar to that of a child—thanks to Bifidobacterium, a Mediterranean diet, daily yogurt, and an active, stress-free lifestyle.
Maria Branyas Morera, who lived to 117, credited her longevity to a healthy gut rich in Bifidobacterium, a balanced diet, and daily physical activity.
Ever wondered what it looks like to have a gut like a child’s, even when you’re 117?
Maria Branyas Morera, who became the eldest person on the planet, until her death in 2024, was astonishing in many ways: living until 117 years showed the world she was indeed unique. Researchers suggest Branyas’ remarkable lifespan may have been because of her “Bifidobacterium” enriched gut. Bifidobacterium is a specially kind of beneficial bacterium that is linked to infants.
It is important to note that her study is not yet peer reviewed, however it was made available in bioRxiv on feb 25 bioRxiv.
Why is Bifidobacterium important?
These microbes are remarkable. They help chronic low-grade inflammation, referred to as “inflammaging,” bolster your immune system, strengthen and preserve your gut lining, and even impact your brain and bone health. In Maria’s case, she had an anti-inflammatory gut environment, which likely contributed to her sharp mental and physical mobility and freedom from major diseases well into her 110s.
Maria’s gut actually looked 100 years younger
Scientists described Maria’s gut as resembling that of a child.
