Common Myth #2: Chewing gum takes seven years to pass through the digestive system.

The Myth:

Chewing gum takes seven years to pass through the digestive system.

The Truth:

Like anything else that enters our mouths and our stomachs, chewing gum makes its way through the digestive system in about a day. Unlike food, chewing gum travels through our bodies relatively unchanged - it comes out in about the same form in went in.
