It's worth saying again, or maybe this is the first time I'm saying it, that I'm always tickled and baffled by people who have a clear sense of "if I eat this, it will make my bowels react like X". I go about my eating as if it had nothing to do with my shitting (and as someone who farts very little, that's not much of a factor either). Maybe people think this about cheese, or bread, or meat, or certain vegetables? I don't know.
One time I ate a bunch of cherries and had to shit shortly after and thought the two might be related.
Also there's a great Nigerian restaurant I go to sometimes that when I get the pepper soup, I can tell when that's the thing that coming out of my butt.
But other than those two things, it's all blissfully unconnected for me. Perhaps it's because there are few forms of fecal output that stress me out. I'm okay with some loose stool if that's the price for food I want. Seems like stomach pain would be more of a deterrent to me, various forms of stool are mostly interesting, not daunting.
All this is despite all my dietary mishegas, which is essentially about cause and effect. But blessedly, so far for me, none of the effect things are digestion-based.
