This review provides an overview of the importance of heme iron in the diet and discusses the two prevailing hypotheses of heme absorption; namely receptor mediated endocytosis of heme, and direct transport into the intestinal enterocyte by recently discovered heme transporters.

2023年4月17日 · There are two types of absorbable dietary iron: heme and non-heme iron. Heme iron, derived from hemoglobin and myoglobin of animal food sources (meat, seafood, poultry), is the most easily absorbable form (15% to 35%) and …

2008年7月14日 · This review provides an overview of the importance of heme iron in the diet and discusses the two prevailing hypotheses of heme absorption; namely receptor mediated endocytosis of heme, and direct transport into the intestinal enterocyte by recently discovered heme transporters.

Iron homeostasis is mainly controlled by intestinal absorption because iron does not have active excretory mechanisms for humans. Thus, efficient intestinal iron bioavailability is essential to reduce the risk of iron deficiency anemia. There are two …

Heme iron is better absorbed by the body than non-heme iron. Certain factors can improve or inhibit the absorption of non-heme iron. Vitamin C and heme iron taken at the same meal can improve the absorption of non-heme iron.

2024年1月8日 · Iron absorption involves heme iron from animal-based foods and non-heme iron from plant-based foods and supplements. Heme iron, present in meats, poultry, and seafood, is more readily absorbed and has a higher bioavailability than non-heme iron.

A compelling candidate for intestinal heme absorption is heme responsive gene (HRG) HRG1, a four-transmembrane-domain heme transporter present on erythrophagosomal membranes that imports heme into the cytosol of macrophages during iron recycling from RBCs .

2023年4月24日 · Eat lean red meat: This is the best source of easily absorbed heme iron. Eating it several times per week can help if you’re deficient. Eat chicken and fish: These are also good sources of...

2023年3月8日 · Many breakfast staples — including eggs, cheese and coffee — can block iron from being absorbed in your body. Our bodies need iron to make hemoglobin, the protein found in red blood cells that transports oxygen throughout the …

Heme iron is absorbed from meat more efficiently than dietary inorganic iron and in a different manner. Thus, iron deficiency is less frequent in countries where meat constitutes a significant part of the diet.
