Its more in relation to excess irons role in cancer cell growth, other factors in the diet may help but you don't want to be promoting cancer growth with a verified factor such as excess iron. Lots of studies on this, iron overload disorders shouldn't be under-estimated either man.

That being said, we must remember that plant non-heme iron is very poorly absorbed so i doubt you'd run into too much issues with excessive plant iron intake, but i still wouldn't recommend it and there is no reason to imbalance other minerals as you may potentially in the process.

Where as if you were taking in 450% of the RDA of heme-iron from animal foods you'd probably run into problems very quickly.

If your relying on plant foods completely for your iron intake then you may benefit from slightly higher intake than the RDA due to plant non-heme irons poor absorption. After all studies show many vegans suffer from low iron status. Pairing plantfoods rich in iron with foods rich in vitamin C can significantly increase the absorption of non-heme iron.

Chromium uses the same receptor sites as iron transport proteins. But high chromium isn't common at all, at least not compared to iron overload and disorders such as hemochromatosis.
