… the pans are likely not “nontoxic” some independent testing and research suggests. Nor are they even “ceramic” – at least not in the way the public broadly thinks of ceramics. Now, regulators are investigating some of the pan sellers’ claims.

Does anyone have a source saying that ingesting cast iron seasoning (burnt fat) is ok?
I just want to make sure I’m not just picking my flavor of cancer. I assume burnt food is better than PFAS (not forever)
The seasoning on cast iron is polymerized oil and it’s chemically bonded to the iron. You’re only really going to be removing the seasoning if you’re using abrasives or scrubbing too hard with steel wool or something like that.

Any loose bits of black gunk that are coming off while you’re cleaning it with a sponge or a scrubby are just burnt food.
Good luck finding an article on point for this sort of thing. I looked for a bit to try to find something to link here, but couldn’t find anything that directly addressed cooking oil polymers. I just wanted to say that you won’t necessarily be eating burnt fat. Seasoning cast iron/carbon steel isn’t necessarily about burning fat onto the surface of the pan, since what you’re trying to do is create a polymerized layer of cooking oil on the surface of the pan. Polymerization can occur well below the smoke point of an oil, you just apply heat to speed up the process. Applying too much heat can actually be counterproductive, since the polymer will carbonize, but you’ll probably never reach this point unintentionally without leaving a pan on the burner unattended. Under normal cooking conditions, any heat degradation of the polymer layer will be made up for with the fresh cooking oil that you’ve used, refreshing the seasoning. If you’re going to use cast iron or carbon steel, you should thoroughly clean any burnt on bits after cooking with dish soap. Modern dish soaps don’t have lye, so you won’t be doing any damage to the seasoning and you’ll only be left with polymerized oil, not burnt fat.
If you do decide to do more research and find something on point, please do share! I wasn’t able to find anything that explicitly pointed towards it being unhealthy, and I’m alright with making a somewhat informed assumption of the risk.
Just use stainless steel and carbon steel if you are worried about that, I honestly use my stainless pans 70% of the time, carbon steel like 20% and my cast iron is that last 10% when cast iron is actually beneficial
Huh, I’m opposite.
It’s likely not ok. But focusing on every source of carcinogen in your life won’t stop you from getting cancer eventually. Eating healthy and using Teflon pans will probably give you a better life than eating like shit on cast iron. No real way to know the future though.
Tritan is a good example of this hyper focus on not consuming bad stuff. It has 3 components, 2 of which imitate estrogen. It’s the plastic that replaced polycarbonate. Which is derived from BPA, but in reality contains very little after you wash it once.
So… the crispy bits that result from the Maillard Reaction (the TASTY crispy bits!) may be a known problem because it produces acrylamide.

“Based on the evidence of acrylamide carcinogenicity in animals, the International Agency for Research on Cancer has classified acrylamide as a group 2A carcinogen for humans.”
