So, the answer is a cheerful yes: spinach can absolutely make your poop dark. It’s a quirk of digestion, not a crisis. Think of it as your body’s way of saying, “Hey, I used all the good stuff from that salad… and here’s the leftover paint.”
Next time you see a dark, mysterious movement in the toilet, just whisper to yourself, “Was it spinach?” If the answer is yes, nod, flush, and go about your day. You’ve got a healthy gut and a sense of humor—what more could you ask for?
Now, go eat another salad. Your insides will appreciate it. Even if the toilet bowl gets a little dramatic.
