Excuse me for posting this, but I am trying to remember where I read recently a study that pretty much disproved that caffeinated drinks dehydrate the body harmfully. In the study, I read that the quantity of water that one needs daily can come from caffeinated drinks in which the caffeine only slightly affect dehydration. The article made it sound like another medical theory had been found to be incorrect.

If anyone remembers reading about this study and could either post here or PM me, I would appreciate it.

Dear WW: above is one study that says caffeine beverages cause net water loss.
This may be true in the; beginning, but I think they failed to take into account
the decrease in water loss in people who drink coffee regularly.
I have known many hospital workers who drank many cups of coffee
during the working hours, and never developed dehydration. I doubt that they
also drank a lot of water.
Of course, caffeine containing beverages should not be a large fraction of
daily fluid intake.

I found the study! It came out of Nebraska.

Two groups were compared--urinalysis and maybe blood tests, too, of caffeine drinkers and water/juice drinkers. Results: both groups were pretty much equally hydrated with the water/juice people doing a bit better, but not enough to make waves.

I'm sticking with my 4-5 cups of coffee during the day and the shot or two of bourbon at night. I detest water except when very, very thirsty.

I remember an ad from the '60s in which a faithful drinker expressed shock when he found out they use water to make Guinness®.

I cannot believe that the Nebraska study was even published with only 18 people in the study. Amazing.

And down at Duke where some researcher did a study of 150 people on low-fat v. Atkins' diet, even that researcher admitted that 150 was too low of a number from which to draw scientifically sound conclusions. Not that conclusions are given much weight, it seems to me, with studies controverting previous studies all over the place.

However, I honestly think wwh has made the most telling point:

If hospitals are run on coffee, then there sure as heck doesn't seem to be much real danger in caffeine.

Remember Steve Allen's oldie about "you-supply-the-answer,I'll-give-you-the-question"?
(sample answer: "UCLA"; sample question: "What do you see when the smog lifts?")

One of my favorites answers is "9-W".
(Edit: 9-W is a major road up the west side of the Hudson River from NYC to the Catskill Mountains. Indeed
it was the way to get there for summer vacations etc. until the Thruway was built.)

So: What's the question?

(answer in I&A "answers to questions" thread)

I think caffeine promotes urine formation somewhat which would explain the differences. I don't think the way caffeine affects the body's hydration should be the major worry though, perhaps more its affect on the stomach and one's sleep. In my eyes caffeine should be classed in the same league as cocaine and amphetamines for it is a stimulant. Depending on dosage it has similar effects to the 'Class A' drugs and it is by no means less dangerous( http://www.pe2000.com/caffeine.htm
It is the perfect drug to exploit workers, keeping people awake and alert for long hours of overtime. Embedded in a long history of colonial domination and slavery it has been very profitable and does not threaten the fabric of our profit-driven society.
A bitter white alkaloid, (C8H10N4O2), mainly derived from tea or coffee, its the world's number three drug and is the number one stimulant. It is the only drug (except perhaps cigs) that has attained a socially and economically sanctioned space in the standard working day, and is even given out for free, which says a lot about its power.
Brown roasted bean water doesn't sound that appealing to most children and the bitter liquid really is an acquired taste, yet more people have to have the stuff more often than heroin. Children, I guess, just become accustomed to the double-whammy of sugar and caffeine at a young age through cola drinks before graduating to coffee or tea.
Starbucks and other such firms have made the habit of coffee intake into something close to a religous ritual, where the addictted return to the same shrine everyday for their morning 'prayer' before the day starts. Strange world.
