We've all been there, folks. That first sip of coffee at work and BAM! You gotta poop. You have no choice but to do the unholy thing in the communal toilets, and blame it all on Rick. But why?
We spoke with Jacqueline Aizen (aka Jacqueline Shimmiezz), registered dietitian and professional belly dancer (apt!) about why, exactly, the roast brews up your gut. Here's what she had to say:
Why does coffee make you poop? What's the science behind it for the layman?
Caffeine stimulates the central nervous system (CNS), which is the brain and spinal cord. The vagus nerve, which controls the heart and the digestive tract, links the CNS to the digestive tract. So stimulation to the CNS will also affect digestion.
Additionally, caffeine contains colon-stimulating agents called theophylline and xanthine. They create contractions called “peristalsis.” This moves particles along the gut, making stool move closer to your rectum, and then suddenly you have that urgent bowel movement sensation.
