Why does coffee make us poop? Scientists gave coffee to rats to find out

Avid coffee drinkers often note that the beverage makes them poop. Now, UTMB research findings indicate it has less to do with coffee’s caffeine content and more about the effects of coffee itself. “Interestingly, these effects are caffeine-independent, because caffeine-free coffee had similar effects as regular coffee,” said UMTB’s Xuan-Zheng Shi. IFLScience!,  Business Standard, Punjab Tribune, Business Recorder and many other media outlets reported the research findings.
