Foods High In Iron

Iron is one of the most important minerals found in foods and is essential for health, physical and mental of the body. The main use of Iron is to transport oxygen to the body, ensure the immunity system is healthy and to produce energy in the body. The body is made of tiny cells, all of which require oxygen to survive. Iron plays a vital role in transporting oxygen to the body because there is iron in hemoglobin of red blood cells, which transports the oxygen to the body.

Foods high in iron contain this trace mineral in some form or the other. There is about 200 milligrams (mg) of iron per pint of blood in the human body system. In an adult, one needs about 3 to 4 grams of total iron to make up hemoglobin. The red blood cells in the body that carry oxygen to various parts of the body contain hemoglobin. This iron also helps in production of myoglobin, that serves as a reservoir for oxygen within the muscle cells and the cytochrome. These cells contain iron rich proteins that help in cellular respiration.

It is important to know this classification in different sources of iron as well, as simply knowing what are iron rich foods is not enough. The risk of anemia is quite high, and it can cause some severe problems unless the body receives a fair amount of iron in it. This is even more valid in the case of pregnant women, as they have to think about providing nourishment for two human beings.

The uses of iron in the human body are as follows:

Iron is used in the production of hemoglobin and certain enzymes that are required for a healthy body.

Iron acts as a catalyst for many metabolic reactions that are essential for cell growth.

Iron is important for the immune system and the proper functioning of the liver.

Iron plays a major role protecting the body against the actions of free radicals.

Iron helps in the transportation of oxygen in the blood to various parts of the body.
