Iron is an important element in blood production. About 70% of your body's iron is found in hemoglobin, which is found in red blood cells, and myoglobin, which is found in muscle cells. Hemoglobin is required for the delivery of oxygen from the lungs to the tissues in your blood. Myoglobin receives, stores, transports, and releases oxygen in muscle cells. With the need for iron, many cereals have been fortified with metallic iron (food-grade iron particles). Metallic iron is broken down in the stomach and absorbed through the small intestine and then utilized in blood production. In this study, several commercially available cereals were analyzed for iron content using atomic absorption spectroscopy (AAS). The amount of iron was determined and found to be within the amount found in the label for popular cereals but lower than the amount found in the label of the low cost cereal samples..
