A diet plan can help reverse prediabetes, according to WebMD. Three servings of non-starchy vegetables a day, foods high in fiber, one to three servings of fruits a day, and substituting whole grain foods for processed carbohydrates can help prevent diabetes.
Green beans, broccoli, spinach and carrots are examples of vegetables low in starch, explains WebMD. Cutting down on foods that are high in calories can also help prevent diabetes. In addition, physical activity is an important part of diabetes prevention, as it lowers blood glucose and body fat. Support from family members and more frequent doctor visits can help monitor a diabetes prevention regimen.
