Drinking a can of fizzy drink a day could increase the risk of kidney stones by almost a quarter, new research shows.
The study found that drinking sugar-sweetened drinks makes the painful stones more likely to develop.
Other drinks - such as coffee, tea and orange juice - reduced the risk, the research by Brigham and Women's Hospital, in Boston, U.S., found.
Dr Gary Curhan said in the Clinical Journal of the American Society of Nephrology: ‘Our study found that the relation between fluid intake and kidney stones may be dependent on the type of beverage consumed.‘We found that higher consumption of sugar-sweetened drinks was associated with a higher incidence of kidney stones.’
