No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question 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.
Questions 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 META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, 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.
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.

OP, please don't trust this one's comments. See following document, sections 6 and 7.
PTFE (teflon) is toxic. As soon as your pan is damaged you should throw it out.
Source : https://pubs.acs.org/doi/10.1021/acs.est.0c03244
That doesn't say it's unsafe to cook with. PFAS, in industrial use, are hella dangerous. But not all PFAS are the same, and Teflon is specifically treated to be food-safe under normal cooking temperatures.
Teflon, sure. But thechemicals and glue used to stick this famously non stic material to a pan, absolutely fucking not.
That isn't how Teflon is applied to cookware.
So, I think this is is where we ask for some reliable research showing that the way that Teflon is applied to the pan is toxic in cooking use
How Teflon is actually applied. It's a physical bond, not a chemical one. No adhesives used. Other dude is just making things up lol
So I've just read that paper and it's very interesting. The vast bulk of it is about the danger of polymer processing aid used during the manufacturer of teflon and how they could leach during manufacture, use and product disposal.
The manufacture and disposal phases encompass environment pollution - important, but not relevant to safety during cooking.
The in-use section of the paper is largely about concentrations used in cosmetics (who knew?) and the potential affects.
What about cooking? There is one line that I could find in the paper - I may have missed something, of course. It says this:
"Fluoropolymer-coated food contact materials (e.g., metal cookware), if not properly pretreated, could lead to the leaching of nonpolymeric PFAS residuals into food during the use phase."
So - if not properly pretreated (I don't think the paper expands on what this means), it could lead to leaching. But the paper has nothing to say about whether this leaching occurs with everyday cookware and if so, if it happens at concentrations that could be harmful.
So I'm going to suggest that this paper does not present any evidence that non-stick pans are harmful to health during cooking.
Thank you for reading the source, the amount of FUD in this thread is crazy.
