After researching the effects of swallowing chewing gum, I found the claim “chewing gum does not take years to leave our intestines” to be true. In other words, the myth that gum will stay in your body for years after swallowing is false. The initial source posted along with the claim is a blog post from Duke Health, the Duke University Health System. Usually, blog posts are not reliable sources but since this one is from a prestigious University, it is most likely trustworthy.
Next, I looked into Nancy McGreal, MD, who is the gastroenterologist referenced in this article. She is no longer working with Duke Health, but I was able to find her LinkedIn profile. She has been working in Gastroenterology since around 2009 and has attended many highly ranked universities for her educational journey.
To further fact check, I googled the question behind the claim, “Does chewing gum take years to leave our intestines?” I found an article from Mayo Clinic, a non-profit medical center as well as a source recognized by News Detective to be reliable. This article states that if swallowed, chewing gum will move through your digestive system and will be excreted in your stool.
I then looked at an article from McGill University’s Office for Science and Society which clearly states that gum will pass through your digestive system within 24-48 hours.
