Many think that coffee helps to go bathroom. And they are right – here see the scientific facts:
“One study, published in 1990 in Gut, a journal of gastroenterology, found that coffee induces a “gastrocolonic response” in some individuals just minutes after they consume the beverage. While the study failed to identify the exact cause of this response, researchers hypothesized that coffee somehow affects the epithelial tissue lining the stomach and the small intestine.
The Gut study also found that coffee promotes the release of gastrin, a hormone produced within the stomach and known to increase motor activity in the colon. As this area of the of the colon is closest to the rectum, researchers concluded that increased activity there could be responsible for coffee’s laxative effects.
While certain health professionals believe it’s the caffeine in coffee that causes heightened motor activity — or contractions — in the colon, the Gut study found that in certain individuals even decaffeinated coffee stimulates the need to defecate. This led the researchers to conclude that it’s not caffeine, but some other substance in coffee that’s responsible for the drink’s reputation as a purgative.” ..
