Not saying that teflon is bad when ingested, but asbestos and glass are also chemically inert and it doesn't make them ok to ingest.

Not saying that teflon is bad when ingested, but asbestos and glass are also chemically inert and it doesn't make them ok to ingest.
- pitaj 4y agoSilicates like glass and asbestos are hard and cause physical damage, but PTFE is a soft polymer.
- labawi 4y agoSmall chemically inert substances can gunk up your cells and tissues even if they are soft.
- jiggawatts 4y agoThe don't make into your cells and tissues, because they're not digestible. Anything bigger than a "small molecule" doesn't make it through the membranes into your bloodstream. Even individual proteins are too big, let alone a chunk of your frying pan big enough to see.
- labawi 4y agoWhen talking about a small polymer, I was mainly commenting on microscopic flakes and lakes laced with "chemically inert" molecules that have devastating physiological effects. Either way, what you claim is simply not true by any reasoning [1], though I do agree eating teflon flakes in moderate amounts should not pose much concern.

- refurb 4y agoAsbestos is not chemically inert. That's why it causes cancer.
- ComputerGuru 4y agoThat’s not how it causes cancer. Its physical properties are incompatible with human biology.
- refurb 4y agoYes it is. Asbestos has chelated iron in it that catalyzes free radicals that result in DNA damage. Saying "Its physical properties are incompatible with human biology." is not an actual answer. What physical properties?
- mint2 4y agoThey are referring to the way any google search on the health effects of asbestos fibers will show that mechanical irritation causes scarring.

- refurb 4y agoPlease don't quote wikipedia. That's a theory from the 70's.
- CorrectHorseBat 4y agoI rather believe Wikipedia than random strangers on the internet
- refurb 4y agoThose are the same. Look at peer reviewed papers.
