Microcosmic Universe Within Humans: Potential Secret to Human Longevity, Scientists Speculate
In a groundbreaking study, researchers from the Josep Carreras Leukemia Research Institute delved into the secrets of Maria Branyas Morera, the world's oldest living person at the time of her death at 117 years and 168 days. Maria, who held the record for the longest human lifespan, had a unique gut microbiome that may have played a significant role in her longevity. According to the study published in the journal Cell, diets rich in fermented foods increase bacterial diversity, and Maria's diet, which included around three yogurts a day, might have contributed to her long life. The researchers found that Maria's cells behaved younger than her chronological age, suggesting a link between her gut microbiome and her health. However, Dr. Freedberg, a microbiome expert, cautions that while the microbiome may influence health, factors such as cardiovascular health, maintaining a healthy weight, having a strong heart, not smoking, and not drinking excessively are more important for longevity. One of the most intriguing findings was Maria's resistance to cancers, which was attributed to her genetic mutations. Yet, the researchers suggest that her lifestyle choices, including her yogurt consumption, may have also played a role in her health insurance. The study also highlighted the potential of using a unique solution to combat C. diff infections—a fecal transplant, where a person receives stool from a healthy donor. This procedure, while controversial, could be a valuable step toward curing chronic illnesses like Crohn's disease and ulcerative colitis. Researchers aim to eventually mimic the formula for a healthy microbiome and grow the bacteria, rather than relying on a donor. This could revolutionise the treatment of various health conditions. Good bacteria in the gut microbiome, such as those found in Maria Branyas Morera's gut, can fight off infections, including C. diff. This underscores the importance of maintaining a balanced gut microbiome for overall health. Emma Frederickson, a science journalist with a background in communication and media, has been covering the fascinating world of microbiome research. Her hobbies include searching for the world's best oat milk cappuccino, and she enjoys writing about topics like climate change, conspiracy theories, and weird biology. The name of the research team that studied Maria Branyas Morera's long life has not been publicly disclosed, but their findings have opened up a new avenue of research into the connection between the gut microbiome and longevity. As research continues, we may uncover more secrets to living a long, healthy life.
