Foods with a wide range of water content (<40 to >80%).
It is normally assumed that the contribution of food to total dietary water intake is 20–30%, whereas 70–80% are provided by beverages. This relationship is not fixed and depends on the type of beverages and on the choice of foods.
There are no European data available, but assuming an increase of energy intake of 15% (equivalent to 300 kcal/day), an additional total water intake of 300 ml would be adequate (EFSA, 2008).
Adequate water intakes for lactating women are about 700 ml/day above the adequate intakes of nonlactating women of the same age (EFSA, 2008).
