Diabetic patients should ensure three meals a day, and then according to the condition can be arranged between meals and bedtime fruit and snacks, the total daily energy to maintain a constant, the energy distribution of each meal and additional meals should be based on the actual situation of each patient to determine. Breakfast preparation time is rushed, the main food can choose some simple preparation of porridge, steamed buns, etc., should be consciously with some coarse grains, temporary preparation of dishes more trouble, generally used to eggs, diabetic patients to avoid high cholesterol intake, should be 2-3 days to eat an egg, but also in the previous day’s dinner set aside part of the secondary heating of meat and vegetable dishes with little change in taste, so that although part of the vitamin loss, but breakfast can intake of a certain amount of dietary fiber. Milk can be arranged between meals and bedtime snack time, depending on the patient’s condition, medication and physical activity. Chinese food should be carefully prepared, not only the amount of the major nutrients, but also pay attention to the appropriate ratio of meat and vegetable dishes, rich color combination of dishes, diversification of cooking methods. If possible, attention should also be paid to more detailed arrangements, such as the intake of several vitamins and trace elements closely related to diabetes, the intake of dietary fiber, cholesterol intake, and the ratio of saturated to unsaturated fatty acids. The preparation of dinner is similar to that of Chinese food, but special attention needs to be paid to the energy supply for dinner, which must be integrated with the specific clear condition of the patient and not be bound to the traditional scheme of energy distribution between meals. The energy of bedtime snack should be included in the total energy of the whole day, and the meal time and specific amount should be strictly obeyed by the patient’s medication time and medication amount, while paying attention to monitoring the change of blood glucose so that it can be adjusted at any time. The principle of fruit adjustment refers to the level of blood sugar, and the amount of fruits with high sugar content and high glycemic index should be relatively small. Avoid eating more fruits because of your own love and demand for them, which leads to excessive energy intake for the whole day. In short, the diet structure of the three meals should be reasonably arranged, with carbohydrates, proteins, fats, vitamins and dietary fibers appropriately matched to achieve a comprehensive and thoughtful nutrition; in special cases, detailed communication with the attending physician and nurse is needed to make specific arrangements according to the medication and blood sugar situation.
