Can you prevent type 2 diabetes? According to registered dietician, Susan Nowrouzi: Yes, you can! She explains that even people with the predisposition for diabetes, or those with pre-diabetes, can prevent the disease by changing or adjusting their lifestyle. Keeping a healthy weight, eating low-glycemic-index foods, yet high in fiber, like fruits and vegetables, watching the portions of every meal, and doing exercise every day can significantly reduce the chances of getting type 2 diabetes. Susan also suggests what you should and shouldn’t drink, as well as tips on artificial sweeteners.
