Leeches iron into the food unfortunately. Many negative effects from heavy metals in the body.

@Laser can explain better, but many of the issues humans face today are not correctly attributed to almost everyone having crazy levels of heavy metals in their bodies. From foods, vaccines, cookware, environment (and yes, the air) It’s a good rabbit hole to go down

Damn, disappointed to hear, since I love my cast iron. Will do some research, thanks!
