For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

    Let’s stick with the iron in your hemoglobin for some more weirdness. The body knows iron is hard to uptake, so when you bleed a lot under your skin and get a bruise, the body re-uptakes everything it can. Those color changes as the bruise goes away is part of the synthesis of compounds to get the good stuff back into the body, and send the rest away as waste.

    In the other direction, coronaviruses can denature the iron from your hemoglobin. So some covid patients end up with terrible oxygen levels because the virus is dumping iron product in the blood, no longer able to take in oxygen. I am a paramedic and didn’t believe this second one either, but on researching it explained to me why these patients were having so much trouble breathing on low concentration oxygen… the oxygen was there, but the transport system had lost the ability to carry it.

      I had to take iron supplements in the past because my periods were so bad that I would lose my vision and pass out from loss of blood.

          Before using cast iron daily, when I donated blood my iron levels were regularly at the lowest allowable limit or sometimes too low to donate. Once I started cooking with cast iron, I started getting comments about how great my iron levels are every time I donate.

          That is super interesting information and kind of makes sense with the seasoning involved.

          But I recently learned you can get different enamel types that you don’t have to season.

            I would think an enameled skillet would not provide any extra iron; the glass that the enamel is made of forms a barrier between the iron and everything else. That’s nice because you don’t have to worry about it rusting any more, but it also means no iron in your food.

              Yeah, its like a trade off. I’m uneasy about having to season a pan for some reason. I’m pretty sure I have OCD and if I can’t clean a dish the way I clean my other dishes it bugs me to some extent.
