Why Does Poop Have Different Colors?

Poop can be yellow, brown, green, or even black because of what’s inside it.

Your body uses food and bacteria to make poop. When you eat something, your stomach and intestines work together to break it down. The color comes from a special substance called bilirubin, which is made when your body breaks down old red blood cells.

If you eat a lot of green food like spinach or broccoli, that color might show up in your poop too! It’s like adding food coloring to paint, the more green you eat, the greener your poop can be.

Sometimes poop looks black, and that’s because it has a lot of iron from foods like red meat or from medicine. Iron turns the bilirubin into something called melanin, which is super dark, just like how your skin gets darker in the sun!

So, the color of your poop is like a rainbow made by what you eat and how your body works, magical and fun!
