novapsyche: a woman of stature circa 1900s peering out of a ring (womanring)

This morning (January 17, 2011), the female anchor during the end of the broadcast of World News Now (currently being continued as America This Morning) spoke of a new 31-oz. coffee drink [presumably at Starbucks, as she mentioned the largest-to-date size as 'vente']. After demonstrating how much liquid is in one container, she stated flippantly that if a person drank all of that, at least they would not be dehydrated.

This is wrong. Caffeine, especially when obtained via coffee, is a diuretic.

I hope the anchors correct this misinformation before their broadcast is over.

If you Google "caffeine diuretic" or "coffee diuretic", you'll encounter many conflicting sources of information. However, the two to which I linked are of the most recent. They also explain that the more voluminous the intake the increased efficacy of caffeine's diuretic effect. 31 oz. of coffee is not in the "moderate to mild" range of caffeine consumption.
