So is coffee a diuretic?

[Michael Caulo]

So is coffee a diuretic? I have heard that recently the fda has reversed its classification from a diuretic to no longer being considered one. I have yet to find anything significantly confirming on either end at the FDA's website. So can you guys help me out, what is the official consideration?

Never mind the research I found was not real recent I am guessing you are looking for something very recent since you said fda's recent discussion

And it says that the dietetic effects of caffeine are well know and then given level (mg) of caffeine. So my inferences is that coffee is a dietetic depending on the caffeine level consumed.

I haven't followed the research closely, but from what I have seen here and there it seems you have to drink a very substantial quantity for it to have that effect. My guess is that some of what seems a diuretic effect is just the consequence of drinking liquids. I don't drink coffee so have been more interested in tea. One of the things I read for that was in reference to whether it was a reasonable source of re-hydration after exertion. There's nothing like a cold glass of ice tea! The advice there was to go ahead - the water you would consume would far outweigh any slight diuretic effect it might have.

Important disclaimer, of course. I am not a researcher; this is just what I seem to be picking up lately.

yes according to docs at work

This seems to always be a controversial topic with arguing perspective but from the research I have done and the feedback from many forums seems to point in the direction that coffee doesn't seem to have as much of an impact as once thought. So the ruling becomes it is not a diuretic.
