A friend asked: Can people with diabetes have a glass of milk before going to bed at night? How big is the effect on blood sugar? Before
talks about this problem, it is necessary to clarify the two concepts about blood sugar rise and fall. One is the increase in blood sugar, and the other is the magnitude of the increase in blood sugar. Many people often confuse these two concepts to control their blood sugar. The above brings some confusion and questions, let's understand these two concepts.
Blood glucose rises Since it is an increase, there must be a basis for comparison. For example, the increase in blood glucose after a meal is relative to the blood glucose before a meal. As long as the food contains carbohydrates, the glucose produced by its decomposition is absorbed into the blood, and blood sugar If the total amount is too much, blood sugar will definitely rise. Almost all foods contain carbohydrates, and blood sugar will rise after eating, but the carbohydrate content of different foods is different, and the total blood sugar after a meal changes also.
The magnitude of the blood glucose increase is the increase in blood glucose compared to the reference blood glucose. For example, how much blood glucose after a meal increases compared to fasting blood glucose. The more the increase, the greater the blood glucose change, indicating that the blood glucose fluctuates more. This is a very important issue in diabetes blood sugar control, because blood sugar fluctuations are more harmful than pure hyperglycemia.
clarified these two concepts, and then look at milk. The carbohydrate content in milk is very small, 3.4 grams per 100 grams, while the carbohydrate content in 100 grams of rice noodles is 78 grams. You can imagine drinking milk Compared with rice noodles, the total blood sugar and the increase range are increased, but the difference is far, almost no comparability. It is normal that the postprandial blood sugar is higher than the fasting blood sugar. Therefore, drinking milk has little effect on the postprandial blood sugar of people with diabetes and is not the main reason for the increase in blood sugar.
It can be seen that people with diabetes can drink a glass of milk before going to bed when the blood sugar control is relatively stable, and it will not have much effect on blood sugar. On the contrary, it is still a recommended practice, because milk contains a lot of High-quality protein, because the body's fat metabolism is most active at night, and after fat synthesis, it can only be used by the body after it is combined with protein to form lipoprotein, so it is beneficial to control blood lipids.
Of course, this is not to say that people with diabetes can drink as much milk as they want. Although milk contains less carbohydrates, it contains higher fats. Drinking too much can lead to increased blood lipids. This is also diabetes. People also need to control the indicators, so you can drink 250-300 grams of milk a day, and the maximum should not exceed 500 grams. If it is made into yogurt, the effect will be better, because yogurt helps regulate the gastrointestinal flora, helps better control blood sugar, and can also prevent constipation and regulate insomnia.
After understanding this knowledge, you will have a correct understanding of the relationship between blood sugar and other foods that you want to eat but dare not eat, such as sweet potatoes, potatoes, pumpkins, yams, etc. In fact, the carbohydrates contained in these root foods Only less than half of the rice noodles, that is to say, eating the same weight of sweet potatoes and rice noodles, no matter the total amount of blood sugar increase or the extent of the increase, sweet potatoes are much less than rice noodles. People with diabetes are completely You can eat, but you need to pay attention not to eat more, and pay attention to the ratio of 2:1 with the staple food replacement. The reason why some people have a higher blood sugar level after eating sweet potatoes is mainly because they have not replaced the staple food accordingly.
