Iron Skillet a Health Hazard?

I recently acquired a forged iron skillet, mainly because my supposed non-stick coated ones have become sticky over the years and I don't want to buy a new one so often.



Now I've come across some articles toting the advantages of ironware because it raised iron levels in food and other articles warning of the dangers of ironware because it raised iron levels in food too much. (1)(2)(3)



Some claimed iron increased by up to 850%, another claimed that it would add "inorganic minerals" to food that displace "organic minerals" in my body (I went on to check whether distinction in minerals is actually accepted science, but only got blather about how in organic minerals "the electrons are spinning clockwise" and whatnot :p).



Did anyone here look into the subject before and came to a conclusion?

The only credible source actually testing for iron level increases that I found is behind a paywall: (4)
