[edit] Caffeine
In an article in National Geographic on caffeine, it explicitly says that caffeine is not a diuretic, however I can only find references to Coffee's affect not being a diuretic (because the water in a cup coffee is much more than the diuretic effect of the caffeine).

I also read the same National Geographic article and remember it saying that coffee did not dehydrate you. I could not determine if the article for diruetic said that diruetics could cause dehydration! -dan (j0)
- I haven't had a chance to read that article but caffeine is considered a diuretic. This effect is seen in relatively high doses, and tolerance to its effects develops rapidly. Thus in most settings, it doesn't really have a diuretic effect as such (Maughan & Griffin, 2003). -Techelf 07:38, 14 March 2006 (UTC)

- I would like to contribute about this topic soon when I have more time. But, searches on pubmed have shown me that it doesn't seem to be a diuretic on the level of the organism. In the kidney caffeine seems to increase cAMP or something and increase glomerular filtration (indirectly by increasing renal blood flow). But, when athletes or sedentary people are given caffeine, their urine output doesn't increase beyond placebo groups, indictating it isn't a diuretic. There is also a specific study that shows that in an athlete, urine production isn't any higher for athletes on caffeine vs placebo. This is relevant because many weekend warriors avoid caffeine while working out due to being afraid of dehydrating, which is not true. Its actually better to take caffeine for its glucose sparring and increasing in mobilization of free fatty acids. Rjkd12 14:43, 1 December 2006 (UTC)

[edit] Diuretics as a Banned Substance in Sports
This article needs information as to why diuretics are banned in sports (what athletes gain from taking them, what sports ban them, etc...). —The preceding unsigned comment was added by 71.70.136.192 (talk) 14:21, 28 March 2007 (UTC).
