It’s rare to get consensus all round, but when it comes to drinking water the experts agree two litres is too many. In our second instalment of We Asked Five Experts we put to a nephrologist, gastroenterologist, GP, sports scientist and exercise scientist a recommendation you’ve probably been told at least once in your life: do we really need to drink eight glasses of water a day?
All agreed no. In fact, Western Sydney University’s Vincent Ho suggested the eight glasses recommendation may have come from a publication by the National Academy of Sciences Food and Nutrition Board in 1945 stating “A suitable allowance of water for adults is 2.5 litres daily in most instances”.
