Human iron homeostasis is regulated at two different levels. Systemic iron levels are balanced by the controlled absorption of dietary iron by enterocytes, the cells that line the interior of the intestines, and the uncontrolled loss of iron from epithelial sloughing, sweat, injuries and blood loss. In addition, systemic iron is continuously ...
Ferritin genes are highly conserved between species. All vertebrate ferritin genes have three introns and four exons. [8] In human ferritin, introns are present between amino acid residues 14 and 15, 34 and 35, and 82 and 83; in addition, there are one to two hundred untranslated bases at either end of the combined exons.

The human diet contains iron in two forms: heme iron and non-heme iron. Heme iron is usually found in red meat, whereas non-heme iron is found in plant based sources. Heme iron is the most easily absorbed form of iron. In those with hemochromatosis undergoing phlebotomy for treatment; restriction of dietary iron is not required.
Seafood can be an excellent substitute for red meat, and oysters are particularly rich in iron. Slurp down four large mollusks of the mushroom variety and you’ll get 7.8 mg, per the USDA .
Meat can be replaced by, for example, high-protein iron-rich low-emission legumes and common fungi, dietary supplements (e.g. of vitamin B 12) and fortified foods, [152] cultured meat, microbial foods, [153] mycoprotein, [154] meat substitutes, and other alternatives, [155] such as those based on mushrooms, [156] legumes (pulses), and other ...

Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Because iron from plant sources is less easily absorbed than the heme-bound iron of animal sources, vegetarians and vegans should have a somewhat higher total daily iron intake than those who eat meat, fish or poultry. [42] [43] Taken after a meal, there are fewer side effects but there is also less absorption because of interaction and pH ...
