Study reveals genetic traits linked to longevity

Scientists have studied the DNA of Maria Branyas Morera, who was the world's oldest person when she died last year at 117. Born in 1907 in San Francisco, Maria lived in Catalonia, Spain, where she outlived the average life expectancy by over 30 years. She often credited her long life to “luck and good genetics,” as well as a positive social circle. Research showed that her lifestyle and diet contributed significantly to her longevity. She avoided alcohol, smoked rarely, and enjoyed daily walks. Her diet included fruits, vegetables, and three yoghurts each day, which helped keep her healthy. A study at Barcelona University analyzed Maria's genes and found that her cells were biologically 17 years younger than her actual age. Researchers noted that her body efficiently processed fats and maintained good cholesterol levels, lowering her risk of heart disease. Maria's microbiome, which is rich in beneficial bacteria, played a role in her health. Although the exact link between microbes and longevity is unclear, her unique genetic makeup and healthy habits were key to her long life. Researchers hope these findings can lead to breakthroughs in understanding aging and how to promote a longer, healthier life. After Maria's passing, Tomiko Itooka briefly became the oldest person before her death in late 2024. Currently, 116-year-old Canabarro Lucas holds the title. The study emphasizes that old age does not have to be synonymous with poor health.
