Nutrition and Pregnancy - Water

Water

During pregnancy, one's mass increases by about 12 kg. Most of this added weight (6 to 9 L) is water because the plasma volume increases, 85% of the placenta is water and the fetus itself is 70-90% water. This means that hydration should also be considered an important aspect of nutrition throughout pregnancy. To ensure healthy hydration during pregnancy, the European Food Safety Authority recommends an increase of 300 mL per day compared to the normal intake for non-pregnant women, taking the total adequate water intake (from food and fluids) to 2,300 mL, or approximately 1,850 mL/ day from fluids alone.
