Here’s the surprising fact: your body is a terrible artist. It cannot fully digest the dark pigments in cherries, specifically a compound called anthocyanin. This pigment is the same stuff that makes red wine and blueberries look like they were dipped in a midnight sky.
So, when these tiny purple soldiers march through your digestive system, most of them survive the trip. They exit looking exactly as they entered: dark, brooding, and slightly suspicious. It’s not blood; it’s artistic expression from the inside out.
Think of it this way: you ate purple fruit. Why would you expect a yellow rainbow on the other end? That would be a betrayal of basic color theory.
The "Burnt Motor Oil" Stage
Now, let’s get specific. If you eat a few cherries, nothing happens. You’re fine. You’re boring. But if you eat two pounds at a farmer’s market like a feral raccoon, you will achieve what doctors call "melena-lite." It’s not the tarry, sticky black of a bleeding ulcer. It’s a looser, mossy, almost blue-black sludge.
I call this the "Burnt Motor Oil" stage. It’s alarming, but completely harmless. The only danger is that you will spend the next hour Googling "black poop cherry" and convincing yourself you have a rare Prussian disease.
Pro tip: If you want to test this scientifically, eat a pint of dark chocolate cherries. Then, avoid looking in the toilet for 24 hours. Your mental health will thank you.
