Milk is rich in nutrients and is one of the most ideal natural foods. Milk contains water, protein, fat, vitamins, minerals and other nutrients, which can provide more essential nutrients for diabetic patients and is conducive to recovery and longevity. The proteins in milk are mainly casein, lactalbumin, lactoglobulin, etc., and contain 8 essential amino acids. The content and composition of essential amino acids in milk is similar to that of eggs, with a digestibility and absorption rate of 87% to 89%. Milk fat is a high quality fat, not only is it of good quality, its absorption rate is also above 95%. In addition, the carbohydrates in milk are galactose and lactose, which are more easily digested and absorbed sugars. Milk is high in calcium, generally 1 ml of milk contains 1 mg of calcium. Milk is also rich in whey acid, which not only inhibits cholesterol deposition in the arterial blood vessel walls, but also inhibits the activity of cholesterol synthase in the body, thus reducing cholesterol production. It is very important for diabetic patients to consume milk properly as a scientific act. Diabetic patients should drink low-fat milk in moderation. Excessive consumption of milk or high-fat milk can easily lead to diseases such as atherosclerosis. Diabetic patients should drink milk without or with less white sugar or brown sugar, otherwise it will lead to a rapid rise in blood sugar and aggravate the condition, affecting the effectiveness of diabetes treatment. In addition, because brown sugar contains a certain amount of oxalic acid, it can cause the rich proteins in milk to gel or precipitate, causing bloating. The time of day when milk is consumed by diabetic patients should depend on their respective habits. If consumed in the morning, it should be accompanied by eating other cereals, which can play a complementary role of nutrients. A few diabetic patients who drink milk are prone to abdominal distension, abdominal pain or increased anal exhaustion due to lack of lactase in the body, which can be alleviated if a small number of meals are taken or if de-lacticized milk or yogurt is chosen. It is not scientific to think that the nutritional value of milk is higher than that of natural foods, so it can be consumed in large quantities every day. type 2 diabetic patients are mostly elderly people, accompanied by varying degrees of hyperlipidemia, hypertension, fatty liver, etc. It is recommended that low-fat milk be used frequently, about 200 ml each time. The time to drink milk is better during the day, and can be supplemented during meals, or between meals. A few people feel that drinking milk before going to bed helps them to sleep, which may not be impossible.
