Analysis revealed that just 1 gram of chewing gum released approximately 100 microplastics on average, with 1 gram of some gums releasing as many as 637 microplastics. A typical stick of gum can weigh anywhere from 1 gram to several grams, according to various reports.

A new study finds that one piece of gum can release hundreds -- possibly thousands -- of microplastics into your saliva. And researchers warn it may be a hidden source of plastic exposure that many people overlook.

Researchers tested ten different chewing gum brands, and found no difference between synthetic and natural gum.
