Water

Water carries nutrients from the food you eat to your baby. It can also help prevent constipation, hemorrhoids, excessive swelling, and urinary tract or bladder infections.

The Institute of Medicine recommends about 10 cups (2.4 liters) of fluids a day during pregnancy. Water, juices, coffee, tea and soft drinks all contribute to your daily fluid needs. Keep in mind, however, that some drinks are high in sugar and too much can cause weight gain.

Because of the potential effects on your developing baby, your health care provider might also recommend limiting the amount of caffeine in your diet to less than 200 milligrams a day during pregnancy.
