Facts about water
(Sandy - sandign)

"Because most food contains a large amount of water, you obtain approximately 3 1/2 cups from what is eaten over the course of a day. Interestingly, the body's metabolism itself is another source, since -- as it makes and uses energy -- one of its daily byproducts is about 1/2 cup of water. So, if you add up your losses (two cups for the lungs, two for sweating, and six for the intestines and kidneys), you come up with a total loss of ten cups ... not counting any excess lost through perspiration during exercise. Therefore, taking into account the approximately four cups provided by food and metabolism, the average person needs to drink six to eight cups of water daily just to keep functioning well." -- Mother Earth News

"Drinks containing concentrated nutrients, such as milk, sugar-sweetened soft drinks, and salty tomato-based juices, count more as food than drink since they themselves increase your body's water needs." -- N.Y. Times Guide to Personal Health

"A reduction of 4-5% in body water will result in a decline of 20-30% in work performance." -- N.Y. Times Guide to Personal Health

"An athlete commonly loses four or five quarts (of water) in a practice session." -- "Realities of Nutrition"
