Which invites the question: to what defree are these results due to general hydration, verses coffee/tea specifically?

  Coffee containing a diuretic is a pretty poor source of hydration

    It's my understanding that caffeine doesn't have a diuretic effect on chronic users with a tolerance for caffeine. IOW if you drink a few cups of coffee every day, it isn't dehydrating you; but if you don't usually drink coffee and drink a few cups in quick succession, it will have a diuretic effect. https://en.wikipedia.org/wiki/Caffeine#Physical_2 https://en.wikipedia.org/wiki/Caffeine#Physical_2

      caffeine irritates the bladder, inducing urination (often urgently). But the total amount of liquid expelled after drinking coffee is not higher than after drinking an equivalent amount of water. In this sense it is not a diuretic and does not dehydrate you. Separately, enzymes in the coffee bean (not caffeine) also act as a peristaltic.

    Coffee is something like 99% water, though.

    I was under the impression that tea contains a diuretic as well, and always just assumed it was the caffeine in it?

Hyperbole aside, I experienced the exact same sequence of events on this side ^_^ The conclusion, for those of you that are wondering: > We found that drinking coffee and tea separately or in combination were associated with lower risk of stroke and dementia. Intake of coffee alone or in combination with tea was associated with lower risk of poststroke dementia.

They missed out the crucial metric of biscuit consumption along with the tea, for all we know, it was the Hob-Nobs all along.

  I am glad I had finished my coffee before reading this, for had I not, I would now be wiping clean my keyboard and monitor. Hmm, I hear the call of the biscuit tin....
