metallic taste == nutritionally available iron. Also rust is trivial. We once put our cast iron through an oven clean cycle by accident. It rusted all to hell, turned solid orange, but re-seasoning returned it to better-than-ever condition.

Eating a meal always implies eating your cookware and packaging. I don't want to eat chromium and friends, or PFAS. Non-stick is gonna get banned eventually, mark my words.

What's the latest science on whether more iron is a good thing?

If a person is already near optimal iron levels, could cast iron push them over into just a bit unhealthy territory? Maybe not enough that people complain, but what would a sensitive study show?
