Today’s Wonder of the Day was inspired by adreannah from AL. adreannah Wonders, “Who invented gum?” Thanks for WONDERing with us, adreannah!
If you had a choice between chewing on a wad of tree sap, a mouthful of rubber bands, or a stick of gum, which would you choose? If the answer seems obvious, you may be surprised. All three have more in common than most people realize.
Chewing gum has a history—a long, long, loooong history. In fact, the oldest piece of chewing gum ever found is thought to be 9,000 years old!
Before World War II, gum was still made from chicle. That's right! The same stuff the Maya had been chomping on for centuries. Chicle is a latex sap derived from the sapodilla, a native Central American tree.
One of the advantages of chicle is that it softens when warmed by the heat of your mouth. This makes it highly chewable.
After World War II, the demand for gum continued to rise, and chemists began looking for an alternative to chicle. Though some gums are still derived from natural sources, many modern recipes use synthetic rubber bases.
In order to make the gum more palatable, manufacturers mix in sugar and flavorings. As you chew the gum, the rubber releases the flavors in your mouth. Sometimes softeners such as glycerin or vegetable oil are also added to keep the gum moist.
Your teachers may not allow you to snap-crack-and-pop in school, but there are real advantages to chewing gum. While it is no replacement for brushing and flossing, one of the major benefits is that gum can actually help clean your teeth.
As you chew, the gum stimulates saliva production, which helps neutralize acids in the mouth that can lead to tooth decay. Some studies suggest the physical act of chewing gum can also help you stay alert, relax, and curb your appetite for a snack.
