A quick Google turned up this article, which I think I've read before.
Sorry about how I worded the question. I don't know if being more direct would've been acceptable here.
As for the question itself, I just don't get the connection. I don't see how coffee would make me want to do that. Fibre makes me what to do that, not coffee. So why do people say that?
As a person who has always been interested in how the human body functions, it is interesting to note the many and varied claims that arise from time to time - you know: "sugar is bad", "fat is bad", "salt is bad", "carbs are bad", etc. I can't say that I can relate to either the 'Coffee as a diuretic OR Coffee as a bowel stimulant'.
I always drink a lot of water with my coffee simply because the Caffeine 'gees me up' and I find a lot of water tends to 'flush' it out of the system. Maybe it's all in my mind.
Coffee is high in soluble fibre from memory.
It is a diuretic but the amount of liquid in it replaces what you lose. Caffeine relaxes your bladder spincter which makes you want to go wees.
As one who is new to home espresso or any other for that matter (might drink cafe coffee once or twice year), I can tell you from personal experience that since getting an espresso machine last month, that it certainly does - from normally 1 visit a day to 3 or 4! Thankfully none of them a matter of urgency. Strangely I didn't experience this with a plunger and store-bought ground coffee which was my daily drink. Lots of links on this subject if you Google.
Pretty well any hot drink in the AM will have this affect, its not limited to coffee, even hot water will get the job done.
If you want to avoid pooping at a bad time, you'll probably try to plan ahead and visit the bathroom before that long meeting. But how do you make yourself poop on command? Try a hot beverage — coffee works, but so does tea or even hot water.
This advice comes to us from Runner's World, because there are few worse times to hear the call of nature than when you're in the middle of a race — and running is notorious for loosening your bowels. Dr Felice Schnoll-Sussman, a gastroenterologist, explains why hot beverages work:"The warm liquid acts as a vasodilator," she says. "It widens blood vessels in the digestive system and helps increase blood flow and GI activity."
Schnoll-Sussman advises runners to drink a hot beverage in the morning and then sit on the toilet for a while. "Just the act of sitting there for few minutes can bring on the urge to go, even if you don't feel like you have to right away."
Because 'number 1' was taken and 'number 3' made no sense.
