“Chewing gum stays in your stomach for seven years.”

Many of us have heard the cautionary tale: swallow your chewing gum, and it will reside in your stomach for seven long years. This widespread belief has likely been passed down through generations, often originating from well-meaning adults attempting to deter children from swallowing something not meant to be eaten. It’s an easy way to prevent a child from consuming a non-food item, but the seven-year claim is a dramatic exaggeration.

In reality, while the base of chewing gum is indeed indigestible, it does not take up permanent residence in your digestive tract. Our bodies are remarkably efficient at processing what we eat and, more importantly, what we don't. Just like other indigestible components of food, such as corn kernels or fruit seeds, the gum base will simply pass through your digestive system. It travels through the esophagus, stomach, small intestine, and large intestine, eventually being excreted in your stool, typically within a few days.

The enduring nature of this myth can be attributed to several factors. Firstly, the idea of something foreign lingering inside the body for an extended period is inherently alarming and memorable, making the warning stick in people's minds. Secondly, since gum isn't meant to be swallowed, the logical leap to it causing problems if ingested is understandable, even if the "seven years" part is a significant embellishment. This combination of parental warnings and the perceived harmlessness of gum, yet its non-food status, allowed the myth to take root and spread widely.
