I recently used the bathroom and saw something, um, odd looking in my solid waste. I wasn’t sure what it was at first, and of course it was too disgusting to investigate by anything but sight, but it struck me that it looked like a slice of mushroom, which would make sense, since I’ve eaten homemade stroganoff with slices of sautéed white mushroom.
Then I wondered if it was possible that a slice could’ve gotten past my stomach and colon in recognizable form. I know some stuff does that, like the infamous corn kernel sheath, but I didn’t know whether mushrooms could fall into that category. Can it?
Like plants fungi have indigestible cell walls, so if a piece of mushroom isn’t crushed in your mastication it’s not unexpected for it to pass through in a form still recognizable as a piece of fungus.
I had a similar situation as OP many timesbefore, just never asked. I suppose it’s normal and often made me wonder if I only ate corn for a week straight, would a whole corn cob come out.
In seriousness, is there anything that a human could take, a supplement of sorts, that would make digesting these materials be easier? I’m sure I’ve heard of something, maybe it was probiotics stuff, it just seems as if it would be helpful, getting the most nutrients out of food.
