So I'm sure everyone has heard, "don't swallow gum! It stays in your body for 7 years!!!!" Well, this is in fact, a myth! The gum, according to kids health, says that, "Though your stomach can't break down a piece of gum the same way it breaks down other food, your digestive system can move it along through normal intestinal activity. In other words, it comes out the other end when you have a bowel movement (poop)."
The article also said, "Chewing gum is made of either natural or synthetic materials (gum resin), preservatives, flavorings, and sweeteners. The body can absorb sweeteners, such as sugar, and they can add up to a lot of calories if you chew a lot of sugary gum. But the human digestive tract can't digest the gum resin. It's moved through the digestive tract by the normal pushing (peristaltic) actions of the gut. The gum's journey ends during a trip to the bathroom."
So, this has come to an end, that theory of your gum staying in your body. DON'T WORRY! IT'S NOT TRUE!!! (then again, I don't recommend swallowing gum)
