Sugary drinks, including fruit juice, may increase the risk of cancer, according to a study by French scientists.
The study, from the Université Sorbonne Paris Cité, followed more than 100,000 people for five years and concluded that drinking an extra 100ml of sugary drinks a day (about two cans per week) increased the risk of cancer by 18%.
The researchers defined sugary drinks as those containing 5% sugar or more, and included fruit juice, as well as tea and coffee with added sugar.
The study is not definitive, and researchers say more study is necessary.
