Eating any food can not play a role in lowering blood sugar, but through a reasonable diet, it can play a role in controlling blood sugar. For people with high blood sugar, diet and exercise can be taken to control blood sugar. If blood sugar is still high, metformin, acarbose and other hypoglycemic drugs can be applied for treatment as appropriate. 1. Dietary regulation: usually you can eat more low glycemic index, low fat, low cholesterol, high vitamin and high dietary fiber food. For example, tomatoes, celery, apples, chicken breast meat, millet, black rice, mackerel, raw peanut rice, tofu and so on. 2. Exercise therapy: moderate physical exercise, such as jogging, swimming, etc., can also help to control blood glucose and avoid the rise of blood glucose. 3. Medication: If the patient’s blood sugar is high, it can be treated by oral metformin, acarbose, reglaneride and other hypoglycemic drugs. The corresponding medication program should follow the doctor’s instructions. In addition to the above measures, you should also have a regular routine and maintain emotional stability, all of which can help to control blood glucose and avoid a continuous rise in blood glucose.
