A Brazilian great-great grandmother, Maria Gomes Valentim, is the world's oldest living person at the age of 114 and 314 days, Guinness World Records says.
Valentim is the first Brazilian to hold the title after her claim was authenticated by the world records authority.
Previous titleholder, Besse Cooper from Monroe, Georgia, is 48 days younger and is now the "Oldest Living North American."
Valentim was born in 1896, when Queen Victoria was still on the throne of England, in the southwestern Brazilian town of Carangola where she still lives. She was widowed in 1946 after a 33-year marriage and has five great-great grandchildren.
According to the Guinness World Records website she attributes her longevity to a healthy diet that includes a roll of bread every morning with coffee and fruit -- and the occasional glass of wine.
Ninety-nine percent of cases in which people claim to live past 115 years turn out to be false or undocumentable, Guinness said.
