Drinking green: Just say no to bottled water

Drink this up. Despite what the marketers of bottled water have almost convinced us of, there remains little scientific evidence that drinking eight cups of water a day does anything more for your health than make you pee a lot.

A piece in last week's Health Section of the New York Times cites a new study in the June issue of The Journal of the American Society of Nephrology, which reports that researchers can't even find where the "at least eight cups of water a day" rule came from.

"Under normal circumstances," Dr. Stanley Goldfarb, a co-author and a professor of medicine at the University of Pennsylvania told the Times, "drinking extra water is unnecessary. I want to relieve people of the burden of schlepping water bottles around all day long."
