flag María Branyas Morera, the world’s oldest person until her 2024 death, had a youthful biological profile linked to genetics, diet, and lifestyle, according to a study.

flag A 117-year-old woman, María Branyas Morera, the world’s oldest person until her 2024 death, provided rare insights into extreme human longevity. flag Spanish researchers studied her genetics, microbiome, and lifestyle, finding a youthful biological profile despite advanced age, including low inflammation, efficient metabolism, a robust immune system, and a gut microbiome rich in beneficial bacteria. flag She had genetic variants linked to heart and brain health, low cholesterol, and reduced disease risk, along with an epigenetic age 10 to 23 years younger than her chronological age. flag While her telomeres were short, her overall biology suggested resilience. flag A Mediterranean diet, active lifestyle, and strong social ties likely contributed, but scientists stress that genetics, lifestyle, and chance all played roles. flag The findings, published in Cell Reports Medicine, highlight potential pathways for healthier aging, though larger studies are needed to confirm broader patterns.
