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 ...
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 .

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 ...

An analysis of data from more than 8,000 adults in the U.S. revealed that 14% had low iron blood levels, ... The best food source of iron is red meat, which contains heme, Ardehali said, adding ...
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.

Hepcidin is a protein that in humans is encoded by the HAMP gene. Hepcidin is a key regulator of the entry of iron into the circulation in mammals. [6]During conditions in which the hepcidin level is abnormally high, such as inflammation, serum iron falls due to iron trapping within macrophages and liver cells and decreased gut iron absorption.
