Umami is a taste that is stimulated by amino acids and nucleotides. It is a savory, mouth filling, brothy, flavor intensifier that you experience regularly but may have never identified. This is why I think of it as a three dimensional taste.
Iron-deficiency anemia occurs because of a lack of the mineral iron in the body. Bone marrow in the center of the bone needs iron to make hemoglobin, the part of the red blood cell that transports oxygen to the body's organs. Without adequate iron, the body cannot produce enough hemoglobin for red blood cells. The result is iron-deficiency anemia. This type of anemia can be caused by:
The most common cause of iron deficiency anemia is gradual, prolonged blood loss. For this reason, menstruating women are particularly prone to anemia. In men, the most common cause of iron deficiency is blood loss in the digestive tract, resulting from disorders such as peptic ulcer, inflammatory bowel disease, and stomach or colon cancer. Sometimes hemorrhoids bleed enough to result in anemia.
