It Takes 7 years to Digest Chewing Gum
It's a Myth: Much like certain nuts and seeds, chewing gum is indigestible by human digestive systems. But, like any other food, gum progresses through the digestive system and is excreted.
“The gum base is insoluble, just like the fiber base of raw vegetables, corn, popcorn kernels, and seeds,” says Duke University gastroenterologist Nancy McGreal, MD. “Our bodies do not possess digestive enzymes to specifically break down gum base.”
The bottom line: While it's meant to be chewed and not swallowed, chewing gum doesn't stay in your stomach.
