Narrator: This is Science Today. Drinking more than one sugar-sweetened beverage per day is linked not only to increased weight gain, but is a big contributor to new diabetes cases. Epidemiologist Kirsten Bibbins-Domingo of the University of California, San Francisco used a well-established computer model to determine that excess consumption of soft drinks, sports beverages and sweetened juices resulted in about 130,000 additional cases of diabetes between 1990 and 2000.
Bibbins-Domingo: As we watch people over time, people who consume the most amount of soft drinks have the highest risk of developing diabetes.
Narrator: But Bibbins-Domingo says their study is not about demonizing sugary drinks...
Bibbins-Domingo: It's to say that the way we consume these — we drink them now early in the morning or we drink portion sizes that really are about three or four servings of soda — has changed over time. And I think the disturbing thing when you look at the patterns of consumption is not just that these beverages are on the rise, but that the consumption of other beverages like milk in children is actually on the decline.
