Is two litres of water a day too much?

While drinking eight glasses of water a day will do you no harm, it’s not necessary to maintain good health, so says a Melbourne academic.

Australian health and dietary authorities recommended a daily fluid intake of two litres, or eight glasses, but this doesn’t need to be in the form of water. La Trobe University lecturer, Spero Tsindos, says drinking eight glasses of water a day is unnecessary and fluid intake can be derived from fruit, vegetables, juices, tea and coffee.

There is no scientific evidence to support the actual amount of water required to remain healthy. The amounts that are now considered a recommendation stem from guidelines published by the Food and Nutrition Board of the National Academy of Sciences in the US in 1945.

Drinking two litres of water each day may not do you any harm, but it may not do you any good either. If you drink most of your water in one go, then this will merely dilute your urine and may still lead to your body needing further hydration.

In his paper published in the June issue of The Australian and New Zealand Journal of Public Health, Tsindos concludes that water and a well-balanced diet does more good than water alone.
