It is best to drink plain water during pregnancy and not to replace it with any beverage or pure water. Drinks generally contain sugar and carbohydrates, which are unhealthy for the pregnant woman’s body and not very good for the fetus. Pure water contains fewer minerals, and long-term consumption of pure water can easily lead to mineral deficiencies. Under normal circumstances, it is better to drink plain water. The daily intake of plain water during pregnancy should reach about 1900-2000ml. If in the hot summer, you can also moderately increase the intake of plain water, because in the hot summer sweating is more, easy to metabolize. You can also drink plain milk or yogurt in moderation in your daily life, and you can also drink milk powder for pregnant women, but these are no substitute for plain water.
