Is it true that if your child swallows a piece of gum, it will take 7 years to digest? This is a myth. Some of the ingredients in gum are digestible. The part of the gum or anything else that is consumed that is indigestible, will pass through the gastrointestinal tract and be released by the body. It does not stick to the stomach or intestines for years. Does that mean that gum is safe? We aren’t suggesting that. It’s not a great choice. After all, gum has no nutritional value, and the primary ingredients are gum base, flavorings and colorings, preservatives, sweeteners and softeners.
