Hi,
It is frequently mentioned that iron absorption is unregulated by the body.
However, this study: http://rheumatology.oxfordjournals.org/content/43/11/1323.full.pdf
shows that is false. More iron in the blood -> more hepcidin -> less iron absorbed.
As another example, more IL-6 -> more hepcidin -> less iron absorbed. This is why there is anemia in chronic disease.
