Three Sisters Recognized as World's Oldest Living Trio
Three Brazilian sisters with a combined age of 316 have been officially recognized by Guinness World Records as the oldest living trio of siblings in the world. The sisters—Zulina de Deus Nunes, 103; Zoraide de Deus Mota, 104; and Levita de Deus Nunes, 109—reside in Rio de Janeiro. Their record was verified through LongeviQuest, a global organization that partners with Guinness World Records to authenticate longevity claims.
Scientific Study Seeks Genetic Secrets
Researchers are now studying the sisters as part of the DNA Longevo Project, led by scientist Mayana Zatz from the University of Sao Paulo. The project aims to investigate biological factors behind aging. The sisters credit their longevity to a healthy diet and active lifestyle. Zulina recalled a childhood spent swimming and fishing in rivers, noting: "Everything was fresh. We didn't have a refrigerator." Zoraide added: "Breastfeeding is incredibly important."
Ordinary Lives, Extraordinary Age
The sisters led ordinary lives. Levita worked as a craftswoman and later at a television network. Zoraide worked as a nurse and raised five children, while Zulina, a stay-at-home mom, raised six. Levita reflects on her life without regrets, stating: "I had a good childhood and adolescence. I can't complain."
Genetic and Community Factors
Ben Meyers, CEO of LongeviQuest, explained: "When sisters reach that age, there is clearly a strong genetic component. But because they live near each other, they also have a support network, with family able to help when needed. There is definitely a community aspect as well." Researchers will compare nonagenarians and centenarians with people who have developed frailty, cognitive decline, or chronic diseases to identify traits linked to longevity.
DNA Testing for Protective Genes
Zatz, who coordinates the university's Human Genome Research Center, said: "Through DNA testing, we look for protective genes, and we know there are several of them. The more people we have who live past 100, especially families with multiple centenarians, the more accurate our research will be in identifying them." Scientists believe inherited factors may play a larger role than environmental influences in preserving health and function later in life. The study's goal, according to researcher Joao Paulo Guilherme, "is to reach 500 centenarians so we can draw more definitive conclusions about longevity."
