The old myth that gum takes seven years to leave the digestive system of the human body is false. It's true that gum is made of largely indigestible material like synthetic gum base and various preservatives, however the gum still exits the body at the same time other consumable items do. This claim fails the extraordinary claim test of scientific reasoning. The extraordinary claim that gum takes seven years to leave the digestive tract of the human body lacked the appropriate extraordinary evidence to back it up. As a result, the claim did not stand up to closer scrutiny.
