Q: How long does it really take to digest gum? My second grade teacher said thirty days. -Savannah
A: It's a lot less than thirty days - more like thirty hours. After you chew the sugar out of gum, if you swallow it the gum passes through your body like any other indigestible fiber. Just like the fiber in lettuce, bread or any other food, gum will pass mostly unchanged through your intestines and come out the other end in one or two days.
