Eisenabsorption

Eisenabsorption refers to the process by which the human body takes in iron from food. Iron is an essential mineral required for numerous bodily functions, including the production of hemoglobin, which carries oxygen in the blood, and myoglobin, which stores oxygen in muscles. The majority of iron absorption occurs in the duodenum, the first part of the small intestine. There are two main forms of dietary iron: heme iron and non-heme iron. Heme iron, found in animal products like meat, poultry, and fish, is absorbed more efficiently than non-heme iron, which is present in plant-based foods such as legumes, grains, and vegetables. The absorption of non-heme iron is significantly influenced by other dietary components. Vitamin C, for instance, enhances non-heme iron absorption by converting ferric iron (Fe3+) to ferrous iron (Fe2+), which is more readily absorbed. Conversely, certain compounds like phytates in grains and legumes, and polyphenols in tea and coffee, can inhibit iron absorption. The body's iron status also plays a crucial role; when iron stores are low, absorption increases, and when stores are high, absorption decreases. This regulation helps maintain iron homeostasis and prevent iron deficiency or overload.
