The treatment of diabetic foot begins with good blood sugar control. Therefore, dietary control is necessary for diabetic foot. For diabetic patients, it is required to eat three meals a day at regular times and avoid multiple smaller meals or snacks. Foods such as fruits, nuts, and those high in fats should be eaten less frequently. Additionally, liquid foods like soups and porridges should also be reduced. Only when blood sugar is well-controlled can the treatment of diabetic foot be effective.
