- Water balance -

 

Water is an essential nutrient but the amount needed depends on climate, activity and the kinds of food we eat.

Most foods contain significant amounts of water and can contribute about half the body's daily water needs. The chemical processes within our bodies that break down food can also provide about 12 per cent of the daily water needs.

Figure 18 shows a balanced daily input and output of water, under conditions of average temperature and humidity.
