That stat comes from a study of tens of thousands of people across Europe—and mirrors similar findings in North America. (But here the risk was 25 percent higher.) Drinking a lot of sugary soda is associated with a higher body mass index (BMI)—and higher BMI is associated with diabetes, so that probably explains the effect. The authors found that fruit juice consumption didn’t boost diabetes levels like soda did. Although there is a lot of sugar in juice, it’s still a better option health-wise than that bottle of pop.
