The health recommendation to drink six to eight glasses of water a day is "thoroughly debunked nonsense," a doctor wrote this week in a commentary in the British Medical Journal. Many health departments and organizations tout the need to drink that much water every day, but there is no high-quality scientific evidence to support the recommendation, wrote Dr. Margaret McCartney, a general practitioner based in Scotland. Some organizations backed by bottled-water makers -- such as Hydration for Health, created by the makers of Volvic and Evian -- say that it's important to drink 1.5 to 2 liters (about 6 to 8 cups) of water a day, and that being even mildly dehydrated plays a role in disease development, McCartney wrote. |
