Why Drinking Coffee Makes Some People Poop

American Chemical Society series Reactions ventures to explain the science behind why drinking coffee makes some people poop. Although scientists have looked into the matter, the process that leads about 30% of people from the coffee counter to the bathroom is not fully understood. The episode does explain the direct effects a few of the more than 1,000 compounds found in coffee have on the body, and more specifically the effect they have on the process of pooping.
