Pregnant women can drink milk throughout pregnancy, and the best time to drink it every day is at night before going to bed or at breakfast time. Milk is rich in calcium ions, protein and other nutrients. Drinking milk before bedtime not only improves the quality of sleep and shortens the time to fall asleep, but also replenishes calcium to avoid cramps and osteoporosis during pregnancy. A glass of milk for breakfast can be effectively absorbed to provide adequate nutrition for pregnant women, increase resistance and enhance their physical fitness. The shorter the shelf life, the less preservative content and the more healthy and safe it is. Milk should generally be heated for drinking, but boiling is not recommended to avoid nutrient loss and affect the nutritional value of milk. Pregnant women usually need to pay attention to a balanced diet and supplement various nutrients, and a glass of milk in the morning and evening will help meet the needs of maternal and child growth and development during pregnancy.
