Diabetic patients can drink whole milk, because some diabetic patients may have a combination of high blood lipids, worrying that drinking whole milk will lead to an increase in blood lipid levels, which is nothing to worry about. The amount of fat in whole milk is relatively small, and diabetics only drink about 200-250mL of milk per day, so it will not cause a significant increase in blood lipid levels. And diabetics who drink milk properly are very good for their health and blood sugar control. So diabetics can drink whole milk or skim milk.
