Plastic is everywhere. And many products we use in everyday life can expose people to tiny, micrometer-wide plastic particles called microplastics. Now, chewing gum could be added to the list. In a pilot study, researchers found that chewing gum can release hundreds to thousands of microplastics per piece into saliva and potentially be ingested.
Yess, as they accumulate in the body at least.
How is that proof that they’re harmful?
That’s not evidence of anything though.
