Sugary drinks are the largest source of added sugars in the American diet.1 The reason sugary drinks increase
the risk of type 2 diabetes is because they contribute to weight gain, which can lead to obesity (an established
risk factor for type 2 diabetes). One study found that participants who consumed large amounts of sugary drinks
had a 26 percent higher risk of developing type 2 diabetes than those who consumed far fewer sugary drinks.2
