There is no scientific basis for the statement “the best food for repairing pancreatic function”. Generally speaking, blood sugar level can be controlled through diet therapy, exercise therapy and hypoglycemic drug therapy. 1. Diet therapy: It is the foundation of all diabetes treatments. In daily life, choose a low-salt, low-fat and low-sugar diet, avoid fried and pan-fried foods, eat less animal offal, crab roe and other high-cholesterol foods, quit smoking and limit alcohol, and maintain a healthy weight. 2. Exercise therapy: moderate aerobic exercise, such as jogging, swimming, playing tai chi, etc., and maintain sufficient sleep, go to bed early and get up early. 3. Glucose-lowering drug therapy: diabetic patients with unsatisfactory blood glucose control after simple diet and exercise therapy can follow the doctor’s instructions to regulate oral treatment with glucose-lowering drugs such as acarbose, metformin and insulin injection. Patients are advised to check their blood glucose regularly and seek medical advice if they feel unwell.
