>A friend sent me the following info. How much of this would you
physiologist types consider to be true, especially about >dehydration?
I can't speak for the observations about Coca Cola, although I know it can
dissolve a lollipop in about ten minutes!
>From what I have heard and read, the stuff about dehydration is if anything
understated. There have been loads of studies about how it can adversely
affect performance, and none of the observations seem unreasonable.
However, I usually do not trust actual percentages unless someone either
cites the study or is extremely detailed in his discussion. For instance,
drinking 5 glasses of water daily supposedly decreases the risk of breast
cancer by 79%. Compared to what? Drinking zero glasses? What did the
control group drink? Were there groups that drank 4 glasses or 6 glasses?
How big is a glass - 12 ounces? What percentage of the change could be
attributed solely to the water (I can't remember the statistical term for
that figure)?
