An interesting story on water

I got this from another support group I belong to. My personal

experience supports the writer's conclusions.

No Need to Guzzle All That Water, Expert Says

WASHINGTON (Reuters) - Trying to do the " right " thing by drinking

eight full glasses of water a day may do little more than make a

person run to the bathroom, a researcher said on Friday.

Newspaper articles, health and beauty magazines all advise drinking

at least 8 full glasses of water a day totaling 64 ounces for optimal

health -- an approach called " 8x8 " by proponents.

But Dr. Heinz Valtin of Dartmouth Medical School in New Hampshire

said there is no scientific evidence to back up this advice, which

has helped create a huge market for bottled water.

" After 10 months of careful searching I have found no scientific

evidence that supports '8x8', " Valtin, who has written textbooks on

the subject of human water balance, said in a telephone interview.

Writing in the American Journal of Physiology, Valtin, a kidney

specialist, said people forget that the food they eat also contains

some water.

The Food and Nutrition Board of the National Research Council ( news -

web sites) has recommended that people take in about one milliliter

of water for each calorie of food eaten.

This adds up to two liters, or 74 fluid ounces on an average 2,000-

calorie diet. But the National Research Council also noted that much

of this is already contained in food.

" I did 43 years of research on that system -- the osmoregulatory

system. That system is so precise and so fast that I find it

impossible to believe that evolution left us with a chronic water

deficit, " Valtin said.

LOW ON FLUID

If a person gets low on fluid, the body compensates by bringing fluid

back out of the kidneys and by slowing the loss of water through the

skin, Valtin said. Thirst kicks in long before dehydration starts, he

added.

" It does it very quickly and very accurately and it does so in

minutes, " Valtin said.

He said he and colleagues became concerned after seeing dozens of

newspaper and magazine articles urging people to sip water all

day. " I started talking to my colleagues and asking them 'Do you know

of any evidence for this?'. Invariably, they said, 'No I think it's a

myth', " Valtin said.

The journal asked him to review all the scientific studies he could

find and he concluded that someone misinformed has been telling

people to drink large amounts of water when most do not need to.

" I am referring to healthy adults in a temperate climate leading a

largely sedentary existence, " Valtin said. " Persons with certain

diseases must have large volumes of water -- kidney stones are

probably the most common example. "

The rest can just drink enough to slake thirst -- and this includes

coffee, tea, and even beer -- despite their diuretic effects, Valtin

said.

He hopes people will be relieved of the guilt of not getting enough

water, and of the expense of buying bottled water to drink throughout

the day.

" There is also the possibility that if you drink a lot of water that

happens to be polluted then of course you get more pollutants, "

Valtin said.

" Then there is the inconvenience of constant urination, the

embarrassment of having to go to the bathroom all the time, " he

added.

And overdoses of water can cause water intoxication that can lead to

confusion and even death. Water intoxication is one deadly effect of

taking the drug Ecstasy, for instance, because it makes people

thirsty beyond their physical needs.

I just can't buy into this " research " . I do know that when I drink lots of

water, my skin is soft, my face looks better and feels better to the touch, I

lose any puffiness around my eyes and I just generally feel better. Plus I

doubt if there is much water in " dense " protein. Maybe in fruit and veggies,

but for those who keep those to a minimum because of the carbs (not me), they

wouldn't be getting any water from their foods, I wouldn't think. Of course, I

just really enjoy drinking water. It's my beverage of choice, beyond health

reasons, just because I like it. That's just my 2 cents.
