If we're talking about health and cookware, you're not going to want nonstick cookware.

- ndsipa_pomu 2y agoIt's fine if it's not scratched and you don't overheat it.
- hanniabu 2y ago> don't overheat it Good luck with that. Temperature isn't perfect and hot pockets of higher temperatures form.
- ndsipa_pomu 2y agoThe problem temperature is 260°C which can easily be avoided by not heating an empty pan (oil/liquids will distribute the heat more evenly) and you'd be unlikely to want to cook at that kind of temperature.
- alwayslikethis 2y agoTeflon is not very thermally conductive, so the bottom contacting the metal substrate may be at a significantly higher temperature than the top. Chemistry reactions have activation energies, and you can generally always trade temperature for time. If it happens in a minute at 260 C, it will still happen at 200 C, just slower.
- ndsipa_pomu 2y ago> If it happens in a minute at 260 C, it will still happen at 200 C, just slower. I don't think that's particularly accurate unless you're considering the action of individual atoms. e.g. Water is considered to boil at 100°C but there will be some water evaporating at lower temperatures but this is a different process that only occurs at the surface. I don't think it's accurate to say that water is "slowly boiling" at low temperatures unless you're reducing atmospheric pressure.
- zeroonetwothree 2y agoWell yes water does evaporate at lower temperatures, it just takes a lot longer. But you’re right we don’t call that boiling.
- alwayslikethis 2y agoThe result is the same though. The water leaves the container and enters the atmosphere as vapor. You can call the former "decomposition", and the latter "leaching", but you are eating the degradation products either way.
- zeroonetwothree 2y agoBecause of the way toxicity works happening slower is quite relevant. Similarly if you drink a bottle of vodka slowly enough you will have no significant health effects but if you drink it in 2 minutes then it’s not going to be great.
- alwayslikethis 2y agoDifferent poisons have different accumulation characteristics. The relevant part here is that perfluorocarbons are fairly persistent in your body. Your body needs a few hours or a day to process the vodka, but the PFAS in your blood takes months/years to leave your body.
