Have you tried maintaining nonstick pans?

I made a comparison between the two, so hopefully you can infer that.

Here, I'll help. Having had both, the cast iron was a massive pain in the ass, and the nonstick pan takes literally no effort to not fuck it up. I don't have a cast iron anymore. I still have nonstick pans.

The study didn’t actually find anything related to cookware. Modern Teflon in the US doesn’t expose people to PFOA/PFOS like old version did due to new regulations. The chemicals could also be entering peoples body’s through drinking water or bioaccumulation in meat or plants. You should throw away nonstick cookware from before 2013, but new nonstick cookware sold in the US does not have PFOA. I believe the EU follow…

So I take it, I should throw out my nonstick pans and just use my cast iron pan from now?

I bought one of these a decade ago - the price has since gone up to $4: https://www.restaurantsupply.com/tablecraft-254-stainless-st... It’ll likely outlive me.

I've seen those used at hibachi and waffle House which probably see a lot more traffic than our homes. Probably a great choice

Yeap, simple mature technology can be refreshing to use.

They have an epoxy coating with on the inside which contains BPA or BPA substitutes like BPB. Tetrapaks have a polyethylene liner and polyethylene and typically doesn’t have plasticizers added.

Do you know why the two plastics are different? I would naively expect that everything that would work as the inner layer in tetrapak would also work in cans (cans deform less). Is it that making the layer stick to tetrapak is simpler/different than making it stick to metal?

I'm not a material scientist, but the two are constructed very differently.

Tetrapaks are laminated, meaning that various layers of solid materials are glued together. Think of it as a sticker on something.

For cans, the epoxy is a liquid coating that's applied by spraying or roller coating, more like paint.

nyc restauranteur frank prisinzano explains it well on his instagram highlights (a kind of mini, continuous cooking course). start with learning his crispy egg technique

https://www.instagram.com/frankprisinzano/ Watched his cacio pepe. He doubled down on reminding to always use dry pasta. Not bad. Subscribed.

try his limone if you liked that one. another expression of simplicity and straightforward principles. I don't know what he currently has up though because he deletes his videos routinely

And, for the cans, it then cures in place. The BPA is like a catalyst and doesn't bind with the material, which is what allows it to leach out so well.

Polyethylene, in addition to being a safer molecule, uses catalysts which don't end up in the final product, which means you can't be exposed to them.

Distill your water, it's the only way to have clean, safe water.

isnt truly distilled water lacking any minerals? i would think you would need to add back (salt, magnesium, calcium etc) whatever was lost or it would be pretty unhealthy. [0] [0] https://healthyliving.azcentral.com/what-are-the-dangers-of-...

It's a myth that distilled water is dangerous.

You get the vast majority of those salts just from the food you eat.

For people who care: thermopaper receipts are absolutely loaded with BPA. Cashiers have measurably higher serum BPA levels, because they touch them all day long. I generally don't take or touch receipts if I can avoid it, but I don't treat them like they're radioactive. The dose makes the poison, and I haven't figured out how to completely eliminate them and still function in society.

With the initial Covid protocols training everybody into becoming constant receptacles for hand sanitizer, thermal receipt paper is probably worth being concerned about at this point. Using hand sanitizer increases the absorption rate of BPA and other chemicals by a factor of 100 or more - https://www.newsweek.com/hand-sanitizer-speed-absorption-bpa...

printing with ink is not madly expensive. Thermal paper should just be banned. Its a ridiculous product anyway the way it just goes blank long before the warranty expires.

https://www.digitalcheck.com/receipts-thermal-ink-costs/ > There’s one other small difference that’s become important in the battle between thermal and ink: the use of company logos on receipts. As it turns out, this is a key factor in the cost of paper, and tips the break-even point in favor of thermal if you want your receipts to have a distinctive look. Ordinarily, plain receipt paper can be had for as little as 40 cents per 150-foot roll, while thermal paper comes in longer rolls (220 or 230 feet) that cost around 80 cents – so you get 25-30% more paper for your dollar with the standard variety.

My wife and I tossed out all the Teflon cookware we had about 25 years ago and replaced it with cast iron and stainless steel. We've not missed it at all.

The thing I dislike about cast iron cookware is that it is extremely heavy. I sprained my elbow last year and couldn’t use any of my cast iron pans for three months. My mom hates them too, and avoids using them whenever she visits.

God, this. I've got tennis elbow and I dread lifting heavy cookware.

I appreciate you updating your comment with an informed update that contradicted your initial argument. When a consumer chemical is discovered to be harmful, there's a tendency from companies to ask their research chemists to come up with a new chemical that shares the same beneficial properties but without the baggage of the provably dangerous chemical. There's a VERY good chance that the new chemical simply hasn't…

I do not trust BPA-free plastics either. I have switched from cans to tetrapaks where possible. My confusion came from some misleading industry documents I read which suggested that PFOA/PFOS/C8 had been replaced with a process that did not require fluorosurfactants. I feel like the information about these chemicals is so confusing, it's hard for a non-chemist like me to understand.
