How do sugary drinks lead to this increased risk? Weight gain may explain the link: In both the Nurses’ Health Study II and the Black Women’s Health Study, women who increased their consumption of sugary drinks gained more weight than women who cut back on sugary drinks. (26, 28) Several studies show that children and adults who drink soda or other sugar-sweetened beverages are more likely to gain weight than those who don’t, (28, 30) and that switching from these to water or unsweetened beverages can reduce weight. (31) Even so, however, weight gain caused by sugary drinks may not completely explain the increased diabetes risk. There is mounting evidence that sugary drinks contribute to chronic inflammation, high triglycerides, decreased “good” (HDL) cholesterol, and increased insulin resistance, all of which are risk factors for diabetes.

Even if you have not been told that you have prediabetes, you could be worried about it, since 90% of the people with prediabetes are unaware that they have it. You are at higher risk if you are over 45 years old, do not get much exercise, have a family history of diabetes, or are African American, Native American, Hispanic/Latino, or Pacific Islander.
