Does decaf coffee make you poop?
The compound responsible for making people have to poop is called theophylline and is created when caffeine is metabolized in the liver. Theophylline relaxes the smooth muscle in your body. However, this isn’t the only thing in coffee that makes you have to go, otherwise soda would do the same thing, right?
Scientists know that this is one compound that affects the body from coffee, and that any sort of coffee (even decaf) can trigger the distal colon, which makes you poo. So yes. decaf still makes certain people poop. If regular coffee does it, then probably decaf will too.
