Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Polymer != Plastic. Plastic is a polymer, but not all polymers are plastic. Wtf is this source.
A lot of gum base is made from plastic. Below are some more sources.
These ingredients are hidden behind “trade secrets” so they aren’t listed on the wrapper.
The irony about asking if gum could be made from a plant source — what do you think it was made from originally? I’d much rather chew on chickle than something that’s going to deposit petroleum-based microplastics in my gut. I get enough of that from food packaging already. “Natural” gum bases still exist and if you Google around you can find lists of chewing gums that still use them.

Your first link is about micro plastics, and they even say not all brands have them. So if a product is made of plastic and doesn't always contain micro plastics (which are found in the air and water and soil and foods), then....polymers might not actually be plastics sometimes. Or in gum, many times.
Random person who took a material science course in college here, polymers like polyethylene are constructed from their component monomers in chemical reactions. Not all monomers end up in a polymer chain, and some remain trapped in the material. These are what leeches out of the plastic over time. Better manufacturing processes have cut down a lot on this over time but it's not something that can be eliminated entirely. These are also referred to as micro plastics sometimes, and sometimes not--it depends on the knowledge of the person speaking and whether or not it suits their point. Anyways, there's your not so fun fact for the day.
Well I'm glad you have this secret knowledge of the plastics hidden from everyone but you.
Phew!
It does cite an FDA statement and federal regulations that allow polyethylene as an allowed ingredient in "gum base." Other sources are more broad just calling it "polymers."
But this points out that "gum base" is a very vague term that can include lots of ingredients. Which kinda sucks.
It's also used in fiber supplements.
Are you sure your aren't thinking of osmotic laxatives? Miralax, for example, is polyethylene glycol.
You are correct.
Like another response stated, the big concern to me was the ambiguity that companies are allowed to have behind “gum base” as an ingredient, and this article dove into that more than others I could find on short notice.
I have no buy-in to the source, so please downvote and report to remove it for infactual information! I will leave it here to foster thoughts and discussion around unusual sources of unexpected materials we may unwittingly put into our bodies.
I’ll admit lately I get more than freaked out anytime I hear about potential microplastics getting into my system orally. It would be a relief to know this is a false alarm, though I’ll still personally be looking into alternatives instead of grabbing whatever off the checkout lane next time.
It's largely not worth freaking out over, in the sense that they are ubiquitous enough that it's impossible to meaningfully avoid. By all means reduce your exposure if you can do so without great inconvenience, but we are all collectively inundated with the stuff and just have to wait for science to figure out what effects (if any) it will have. "Only worry about what you can control" and all that.
It is 100% discretionary product. People can just stop buying it and deny corporate revenue
Rubber and plasticizers but the idea is an oil based product.
Also silk, wool, cellulose, protein
That's why you shouldn't swallow it. Like toothpaste it stays in your mouth until you are done with it.
If you eat celery or beans, I've got bad news for you
Alright, what is it? Lol
whispers you're eating polymers. The bad part of gum.
But not oil based polymers in celery or beans. I am not following.
That commenter is being dense on purpose as some sort one up...
Bad faith behavior
