Anemia is a condition in which the blood is unable to carry sufficient oxygen from the air we breath to the tissues of our bodies, as mentioned earlier (Chapter 12). Among the consequences of severe anemia are pallor of the skin, shortness of breath, extreme weakness, heart palpitations, and death. In contrast, the symptoms of mild anemia may be so vague as to be ascribed to boredom, laziness, or neurosis. The three nutritional factors most commonly associated with anemia are vitamin B12 (Chapter 12), folic acid (Chapter 13), and iron. Of the three, iron is numerically the most important. It often is said that anemia caused by lack of iron is the most common deficiency disease in the world.
