Diet Coke is showing a blurb on the side of its 12-pack box saying how wonderful it is as, and that research shows that it is, a rehydrating agent (like, "use this to replenish your body's lost water".)

Is this just extrememly irresponsible, or has anyone heard any research indicating that caffeine *isn't* the great antihydrant?

It's called whole milk.

I'm sure it just means that its net rehydration is greater than its net dehydration

Probably...the puffery said that any beverage was good for rehydration, so that sounds like what they were *legally* saying, even if the implication was "it's great! Drink it after a marathon!"

I didn't think caffeine had anything to do with it... I thought sugar was bad for dehydration, and that's why soda is bad if you're not getting a ton of water, but since it's Diet coke, maybe that's not a problem?

As far as I know, caffeine is a diuretic, and will help dehydrate you. I've read some military survival guides that warn agaisnt drinking coffee in desert-type situations, because it does more harm than good, liquid-wise.

I'm mostly wondering if there's some new piece of research that, in the same way that eggs are sometimes just great for you, other times death on a plate, has changed that...

According to WebMD's entry on diarrhea and dehydration, soda is one of the fluids reccomended for staving off the worst effects of the dehydration.

The catch: they strongly reccomend it be caffiene-free.

I will say this, though: I drank a fair amount of coke the morning I woke up with the dehydration-induced fever and accellerated pulse, and it helped out a fair bit. I'm sure water would've helped more, but I don't buy bottled water, and have you tried Austin tap water lately?

Caffeine is a diuretic, yups. I can't see how soda could be seen as staving off dehydration any better than water unless its for the salt content or if it has trace amounts of other electrolytes. I do likes the Sprite or 7up when ill. Caffeine free... gots yer salts too! And helps settle the stomach. Other than that, I'd stick to better alternatives like water and bananas and baked potatoes with butter and salt for the hydration and electrolytes.

Oh.. and Ewwwwwwwww Coke!
(horray Dr. Pepper!)

I'm with you on the Dr Pepper front :) Whines has been investigating Splenda-based sodas lately, which really only leaves us with Pepsi One and Coke with Splenda...not a lot of options :(

awwww =/
Well, there is talk about artificial sweeteners being excitotoxins and not being metabolized well by the body anyways. More evidence that the gods hate the CocaCola company!
