Soda, fruit drinks and juices, sports drinks, energy drinks, and other sugar-sweetened beverages are the No. 1 source of added sugar in American diets. A recent study found that drinking one or two sugary drinks a day raises the risk of type 2 diabetes by 26% compared with those who limit sweet drinks to just one a month.
But sugar alone isn't to blame for diabetes. Diets that are high in calories from any source, like sugar or fat, lead to weight gain -- and being overweight raises your chance of type 2 diabetes.
