Especially, the iron absorption rate decreases by 50% with every 5 to 10 mg of phytic acid consumed.  Tannin acid is a contributing factor to iron deficiency in vegetarians and vegan since they block the absorption of iron. Many types of research have shown that phenolic acids in coffee are the main cause of the decline of iron absorption. Se hela listan på mayoclinic.org Absorption of iron is inefficient Although an adequate supply of dietary iron is essential, you might be surprised to learn that the absorption of iron from the food we eat is relatively inefficient.

Hepcidin levels were higher in the consecutive-day group.
Medicine/Biochemistry lesson on iron absorption, transport in the blood, metabolism and regulation of iron uptake in the body.NOTE: There is a mistake in thi
What Decreases Iron Absorption (These 4 Things) Boosting your iron absorption is important, but it’s also vital to reduce factors that might be getting in the way of how well your body is using iron in the first place. In fact, many of the things that get in the way of iron absorption could be at the root of an iron deficiency. This animation describes the mechanisms for the intestinal absorption of heme and non-heme iron. Enjoy! growth iron absorption must exceed iron loss by about 0.5 mg daily in order to maintain a body iron concentration of about 60 parts per million (1, 2) An adult male (70 kg) has a total body iron of about 4 grams which remains constant through-out adult life (Fig. 1). This is maintained by a balance between absorption and body loss of iron.

An exquisite balance between dietary uptake and loss maintains this balance.
