Really?
I hope that the rest of the information you provide is more
accurate than this.
Have a look at:
http://ajpregu.physiology.org/cgi/co...ull/283/5/R993
It turns out, if the above article is correct, that 64 ounces of
water a day is a myth which has never been established by any
scientific study. Actual numbers range from half that to 3-4
times that, depending on the circumstances of the individual -
body mass, age, environmental temperature and humidity, activity
level, and so on.
The role of caffeine as a diuretic is also questionable. One
study that actually tested it found that "advising people to
disregard caffeinated beverages as part of the daily fluid intake
is not substantiated by the results".
There are a lot of well meaning people who read third hand
medical advice that amounts to little more than myth propagated
in shlock magazines and internet sites - and assume they are
reading scientific facts. They then re-publish those supposed
"facts" and re-inforce the myths.
This isn't doing anyone any good.
