Patients with gestational diabetes can drink pure milk, which contains rich nutrients such as protein, fat, vitamins, and minerals. Milk protein contains essential amino acids for the human body, and milk fat mostly consists of short-chain and medium-chain fatty acids, which are easily absorbed by the human body. Moreover, milk is rich in calcium, making it suitable for pregnant women to supplement calcium. The daily consumption of milk can be 500mL, taken in two to three servings, choosing either pure milk or skimmed pure milk. If unsweetened yogurt is available, it is also acceptable to drink. It is important to note that one should try to avoid buying milk powder, as it often contains some additives that are not conducive to blood sugar control.
