Diabetics can drink pure milk containing lactose, but in moderation. The raw material of pure milk is mainly raw cow’s milk, which also contains water, protein, fat and a variety of vitamins, as well as a small amount of lactose. Despite the presence of lactose, milk does not have a high glycemic index of only about 27, which makes it suitable for diabetic patients to drink. Milk not only provides diabetic patients with high quality protein, but also provides energy to make up for the lack of energy brought about by strict dietary control. For diabetics, milk can be used as an extra meal between meals to replenish energy, or plain milk before bed to prevent hypoglycemia at night. For more health knowledge of food, consult a nutritionist and consume it scientifically and rationally under the guidance of a doctor.
