Water Myths
You may have been told that in order to be healthy, you must drink eight glasses of water each day, and each glass must contain 8 ounces of water. You may also have been told that only water will fulfill this requirement, not other liquids that contain either caffeine or alcohol. Both ideas appear to be myths, according to Dr. Heinz Valtin of the Dartmouth College Medical School. In a 2002 paper published in the "American Journal of Physiology," Dr. Valtin found no scientific evidence supporting consumption of eight glasses of water daily. He did find studies that suggested that caffeinated beverages and mild alcoholic drinks, such as beer, can contribute to the water needed by your body.
