Although clinical studies have not reached an agreement on the ideal quantity of water and other fluids we should consume daily to maintain good health, traditional wisdom has long suggested drinking 1.5 to 2 litres (3 to 4 pints) of water per day.
Consuming plenty of fluid helps the kidneys clear sodium, urea and toxins from the body which, in turn, results in a “significantly lower risk” of developing chronic kidney disease, according to researchers in Australia and Canada. The findings, the researchers said, do not advocate “aggressive fluid loading”, which can cause side effects, but they do provide evidence that moderately increased water intake, around two litres daily, may reduce the risk of decline in kidney function. It’s important to keep in mind that the right level of fluid intake for any individual depends on many factors including gender, exercise, climate, health conditions, pregnancy and breast feeding. In addition, people who have already had a kidney stone are advised to drink 2 to 3 litres of water daily to lessen the risk of forming a new stone.
