To control blood sugar well, diet therapy is the cornerstone. If you do not control your diet, eat desserts at will or eat too much at each meal, you will not receive good results even if you apply more drugs. Therefore, every patient should learn how to eat well. Early mild diabetes with simple dietary control can bring blood glucose to the standard without the pain of injections and medication. The first step is to control the total daily caloric intake This amount needs to be set according to the principle of individualization. For example, for medium-sized patients, 20 kcal/kg body weight per day is given for bed rest, increasing to 30 kcal/kg body weight per day for those engaged in light work, 35 kcal/kg body weight per day for medium work, and 35 kcal/kg body weight per day for heavy work. The weight of obese people should be reduced, and the weight of adolescents and pregnant patients should be increased. Standard weight is calculated according to height (cm) – 105. The second step, the distribution of calories Diabetic patients are not unable to eat staple foods, all three major nutrients are needed, and the proportion should be appropriate. Generally speaking, the energy provided by carbohydrates in the diet should account for 50-60% of the total energy. Protein provides 10-15% of the energy. Fat accounts for about 25%. If the patient has overt proteinuria protein intake should be limited to 0.8 g per kg of body weight per day. chronic renal insufficiency will be to 0.6 g per kg of body weight per day. monounsaturated fatty acids are a better source of dietary fat, and a functional ratio of 10-20% is appropriate. Polyunsaturated fatty acids should not exceed 10% of total energy. The intake of saturated fatty acids should not exceed 7% of the total energy of the diet, and minimize the intake of trans fatty acids. The third step, a reasonable mix, long-term adherence to the daily calorie determination, we must think of ways to eat that is scientific and delicious. Here we should talk about the concept of food exchange. The so-called food exchange is the proportion of the nutrients contained in the food is divided into six categories, the weight of each type of food to provide the same calorie, that is, 90 kcal is called one share. No matter what kind of food is one portion, it provides the same amount of calories. It is possible to exchange food, but it is best to do so in the same kind of food. 1. 1 serving of raw staple foods: 25g each of rice, flour, millet, sorghum, corn, oats, buckwheat and beans. 2. 1 serving of fresh vegetables: 500g of green vegetables, eggplant, tomatoes, etc., 200-350g of persimmon peppers, lentils and onions. 3. 1 serving of fresh fruits: about 200g, 500g of watermelon. 4. 1 serving of raw meat or fresh eggs: about 25-50g of animal meat, about 70g of poultry meat and 80-120g of fish. 70g, fish 80-120g. 1 egg. 5, 1 serving of fat: 10g. 6, 1 serving of nuts: 15g of peanut rice or walnut, 25g of sunflower seeds, 40g of watermelon seeds. Conditional patients can develop their own recipes for a week, so that you can do that eat scientific and reasonable, but also change the pattern, which is conducive to long-term adherence.
