Debunked Myths

This classic parental warning is a masterpiece of folklore, designed to terrify children into careful chewing. The myth leverages a kernel of truth—gum base is indeed synthetic and indigestible, made of elastomers, resins, and waxes that resist our digestive enzymes. However, the conclusion that it sticks around for seven years is pure fiction.

Your digestive system is remarkably efficient at moving along materials it can't process. While gum won't be broken down by stomach acids, it doesn't adhere to your stomach lining like it does to a shoe. It travels the same path as everything else you eat, propelled by the powerful waves of muscle contractions called peristalsis. Typically, swallowed gum passes through the entire gastrointestinal tract and is excreted within a few days.

The arbitrary 'seven years' likely gained traction because it sounds scientifically specific enough to be believable to a child. The myth's endurance speaks to its effectiveness as a behavioral tool and our tendency to imagine the body in simplistic, mechanical terms. In reality, your gut is a dynamic system well-equipped to handle the occasional accidental swallowing without long-term consequences.
