Would love to hear some recommendations especially if they are available in Canada. I’ve been chewing a lot of whatever the green and blue version of 5 gum is lately. 5 released a caffeinated version of their gum called respawn but I don’t think it was ever sold in Canada.
Almost all chewing gum contains plastic, and as such stands to be a big source of microplastics in your body (and the environment, especially when not disposed of “properly”).
In the US, companies are allowed to list “gum base” in the ingredients when the “gum base” could mean anything - but it almost always means PVA (polyvinylacetate; a plasticizer).
Some gum marketed to people who realize this uses chicle, as gum originally did, or some other non-plastic, but it needs to explicitly state this. “Gum base” = “not telling you” = undoubtedly chewing microplastics into your body.
