Diabetes is on the rise but many cases are preventable or reversible through lifestyle changes like diet and exercise. A healthy diabetic diet focuses on choosing whole grains over refined carbs to control blood sugar levels. Foods high in fiber and low on the glycemic index are better options. Maintaining a balanced diet from all food groups, eating smaller meals throughout the day, and keeping a food diary can help manage weight and diabetes. Regular exercise in addition to diet changes can significantly reduce diabetes risk. Certain foods like vegetables, legumes, nuts and herbs have properties that may help prevent or treat diabetes.
