Everyone know you’re supposed to drink eight ounces of water eight times a day, right? Wrong. There’s evidently no sound science behind that nutritionist’s mantra, which is loudly extolled (if not expanded upon) by bottled water companies.
In fact, after much thought, nutritionists have come up with this guideline for determining hydration needs: Drink enough so you don’t get thirsty.
I don’t know if it’s true or not, but my doctor once told me that by the time you feel thirsty, you’re already dehydrated – so I guess there is something to the “drink enough so you don’t get thirsty” idea.
