Nutrition Final Project- Iron

The most widespread nutritional deficiency in both developing and developed countries is iron deficiency. It is estimated that one out of every four people in the world is iron deficient. For the most part, iron deficiency affects very young children and women of childbearing age. Many body processes sputter without sufficient oxygen. People with iron deficiency usually feel weak and tired. They have a shortened attention span and a poor appetite, are susceptible to infection, and become irritable easily.

Why is Iron important?Iron is part of hemoglobin, a protein that carries oxygen from our lungs throughout our body. It helps our muscles store and use oxygen. It provides oxygen to muscles, supports metabolism, growth, development, normal cellular functioning, and synthesis of some hormones and connective tissue.

In serious cases, if you have too little iron, you can develop iron deficiency anemia. People with iron-deficiency anemia look pale, are easily exhausted, and have rapid heart rates. Iron-deficiency anemia is a particular problem for infants and young children because it is related to lasting retardation in mental development.

Taking too many iron supplements can cause iron poisoning. Some people have an inherited disease called hemochromatosis. It causes too much iron to build up in the body. The excess iron reacts with cells, causing damage that can result in liver disease, diabetes, and heart failure
