I've written about this-- Here was the first whistle-blower: Valtin, H. (2002). "Drink at least eight glasses of water a day." Really? Is there scientific evidence for "8X8"? American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 283, R993-R1003.

Stephen, any chance you still have that post? If not, perhaps a search of the archives might pull it up and save Stephen the trouble of going through the hoops all over again.

There is no evidence for the benefits of any quantity of water.As to the benefits to the kidneys and skin-there is no evidence. They do support drinking lots of water in severe hot climate prolonged habitat where one may be wise to consume anywhere from 11 to 15 glasses. They point out that we receive 20% of water needs through the moisture in food. But the 8 glasses daily requirement have not being scientifically supported. Btw,when I was running rats at Wichita State and Mizzou we always made sure that there was enough water for the rats.Was that really necessary? or is this just another factor in the domesticated paradigm? We controlled the quantity of food,but boy,did we make sure that they had enough water. Michael Sylvester,PhD Daytona Beach,Florida "give me eight pina coladas."
