Now you can add your favorite chewing gum to the list, thanks to the alarming findings of a new study. Chewing gum, whether natural or synthetic, contains plant-based or synthetic plastic polymers to enhance texture and flavor retention,

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

And if you redecorate your home and sand down the old paintwork, the plastic binders in the paint can release microplastics into the air, which you might then inhale. You could swallow them when you drink from single-use plastic water bottles. Now another source of microplastics in the body has been discovered: chewing gum.
