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:
Anemia can be caused by the body not making enough red blood cells. It is also caused by their loss or destruction. Several factors can cause anemia: Too little iron, vitamin B12 or folate. A shortage of folate can cause megaloblastic anemia, where red blood cells are large and pale (see Fact Sheet 121).
