The surprising truth about your favourite chew
Ever thought your innocent stick of gum could be a tiny Trojan horse for microplastics? Recent research suggests that each chew might be releasing hundreds of these minuscule particles right into your mouth. (sciencealert.com)
What's lurking in your gum?
Most commercial chewing gums are crafted from synthetic rubber, a fancy term for petroleum-based polymers. This gives gum its signature chewiness but also means you're essentially munching on plastic. The packaging often coyly lists "gum base" without delving into specifics. (sciencealert.com)
The microplastic munch
In a study, researchers found that a single gram of gum could release an average of 100 microplastic fragments, with some brands shedding over 600. Considering the average stick of gum weighs about 1.5 grams, that's a lot of tiny hitchhikers per chew. (sciencealert.com)
Should you spit it out?
While the thought of ingesting microplastics isn't appetizing, experts suggest that the small amounts from gum are unlikely to pose significant health risks. However, it's a reminder to be mindful of what we put in our mouths and the potential environmental impact when we dispose of gum carelessly. (sciencealert.com)
A cleaner chew
If you're looking to reduce your microplastic intake, consider switching to gums made from natural chicle or other plant-based bases. Not only are they biodegradable, but they also offer a chew without the plastic aftertaste.
So, next time you reach for that stick of gum, remember: it's not just your breath you're freshening, but potentially your microplastic intake too. Chew wisely!
