Iron (Fe) deficiency is one of principal problems of public health associated with nutrition, specially in the developing countries where the content of hem iron (Fe-Hem) of diets is very low and the Fe non hem (Fe-No Hem) has a bioavailability that usually is low, due to the fact that it is influenced by several inhibitors found in diets rich on vegetables and poor on meats. The aim of this article is to discuss aspects related to the interactions of the Fe and other compounds that modify the bioavailability of this metal, specially in the form of Fe-No Hem, in addition, some key concepts to understand the role of the liver in the regulation of the absorption of this micromineral are discussed
