makes you poop. Wait, let me modify that statement: Coffee makes some people poop. And it encourages others to poop. And maybe not for the reasons you might guess.
The product used to make brewed coffee is commonly referred to as "coffee beans". So it would make sense that people would associate coffee's digestive effects with those of beans (you know, "Beans, beans / Good for the heart / The more you eat them / The more you fart"). However, coffee doesn't actually come from beans. Coffee beans are really coffee fruit seeds. So perhaps the other famed song celebrating beans' digestive effects ("Beans, beans / The magical fruit / The more you eat them / The more you toot") is closer to the truth! But whereas beans are known for inducing gas, coffee tends to cause people to actually poop.
So, coffee's not a bean, but it does make you poop. Ready to learn more? Find out all about the "end result" of your daily cuppa, including who poops when they drink coffee, how coffee makes people poop, how long it takes for coffee to take effect, and more.Does Coffee Really Make You Poop?

The main documented reason for coffee making people poop has to do with a reaction in the distal colon, which is located at the end of the colon. The reasons for this are not well understood, but are thought to have to do with a wide variety of hormonal effects based on the exorphines in coffee (which bind to opiate receptors) and two naturally occurring chemicals in coffee called Gastrin and Cholecystokinin. These chemicals are thought to be absorbed into the blood and directed to the brain and colon. Then, they are thought to stimulate muscle contractions in the lower colon, thus promoting bowel movements in the 20 minutes after coffee is drunk.

, which can also make people poop. And, some say that the caffeine
