Our blood is red because of the iron flowing through our veins, and the lack of iron can critically affect a human’s health. Iron deficiency is a rather common type of anemia, and anemia is a condition in which the blood doesn’t have the required amount of red blood cells. Red blood cells have the essential job of carrying oxygen around the body tissues.
The body suffers when it has insufficient iron due to iron-deficiency anemia. The lack of iron in the human body can’t produce enough of the substance in red blood cells that helps them carry oxygen (hemoglobin). Therefore, it results in iron deficiency anemia, and many times the body is left tired and short of breath.
