What is iron?
Iron is one of the most abundant metals found on earth; it is essential to most
life forms and to normal human physiology. In humans, iron is an essential
component of proteins involved in oxygen transport. It is also essential for the
regulation of cell growth and differentiation.
Where in our body is iron found?
Almost two-thirds of iron in the human body is found in hemoglobin, the
protein in red blood cells that carries oxygen to the tissues. Smaller amounts of iron
are found in myoglobin, a protein that helps supply oxygen to a muscle, and in
enzymes that assist biochemical reactions. Iron is also found in proteins that store
iron for future needs and that transport iron in the blood.
What foods contain iron?
There are two forms of dietary iron: heme and nonheme. Heme iron is
derived from hemoglobin, it is found in animal foods that originally contained
hemoglobin, such as red meats, fish and poultry. Nonheme iron is found in plant
foods such as lentils and beans. This is the form of iron added to iron-fortified and
Red meats Beans
