A groundbreaking study has shed light on the remarkable longevity of Maria Branyas Morera, who lived to be 117 years old, making her the world’s oldest person. Researchers from the Josep Carreras Institute analyzed her DNA and found that a combination of genetic variants, a youthful microbiome, and lifestyle factors, including her remarkable habit of consuming three yogurts a day, may have contributed to her long life. The study revealed that her biological age was lower than her chronological age and identified protective genes that play a crucial role in promoting a healthy lifespan. This research not only provides insights into the secrets of a long life but also emphasizes the potential impact of diet on longevity, suggesting that everyday foods could hold the key to a healthier and longer life for many.
