I suspect you're being downvoted by people who simply recognise your username at this point. It's disappointing because I think your comments for the most part are fine, people just seem to take offence to you not being a vaccine zealot.

In doing my part to stick to the topic at hand, I tried to find some research which supports these claims about stainless steel. It seems like Nickel is typically a component of stainless steel and is generally not something you want to have in your body[1].

I'm also not sure how the additional iron, presumably being processed by the liver, might affect someone who has cirrhosis.

I assume "nothing to worry about at scale" really means "not likely to immediately kill a bunch of people".

Thanks for the feedback and the citation, that was an interesting read.

Here are a couple more good papers I skimmed through today while looking into this topic. I agree on the "not likely to immediately kill a bunch of people" point. From what I can tell, there are very few longitudinal studies evaluating the health outcomes from metallic corrosion and wear from implants.

Citing [1], stainless steel corrosion is associated with "distinct inflammation and tissue reactions in the surrounding soft tissue with high amounts of particles".
