Studying Brazil’s Centenarians
Researchers in Brazil are studying the country’s oldest residents to better understand why certain people live well beyond 100 while remaining healthy. For more than two decades, University of São Paulo geneticist Mayana Zatz has studied nearly 200 centenarians, including more than 20 people over the age of 110. Researchers believe Brazil’s diverse ancestry may give some people combinations of genes linked to stronger immune systems, cellular repair, and resilience. Though genetics are important, lifestyle also plays a major role in life expectancy. Many of the centenarians grew up eating simple, minimally processed foods, stayed physically active throughout their lives, and remained connected to family and community. Researchers have also noticed a common sense of optimism and humor among participants. The findings suggest that longevity may come from a combination of genetics, everyday movement, social connection, and simple habits rather than the expensive and complicated anti-aging routines that are becoming increasingly popular.
