Iron absorption refers to the process by which iron is taken up and utilized by the body. Iron is an essential mineral that plays a crucial role in various biological processes, including oxygen transportation, energy production, and immune system support. The human body requires a steady supply of dietary iron to maintain optimal levels of this important nutrient.
When we consume foods containing iron, such as red meat or leafy green vegetables, our bodies break down the iron-containing compounds into a form that can be absorbed through the intestinal lining and incorporated into hemoglobin (a protein in red blood cells) or stored for future use. The efficiency of this process depends on several factors, including the type of iron source, the presence of other nutrients, and individual physiological differences.
In summary, "iron absorption" refers to the ability of our bodies to take up dietary iron and utilize it effectively for various biological functions.
