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.
Folate deficiency can cause anemia. Anemia is a condition in which you have too few RBCs. Anemia can deprive your tissues of oxygen it needs because RBCs carry the oxygen. This may affect their function. Folate is particularly important in women of childbearing age. A folate deficiency during pregnancy can lead to birth defects.
There are three main causes of anemia: blood loss, lower than normal levels of red blood cell (RBC) production, or higher than normal rates of RBC destruction. More than one of these factors can combine to cause anemia. Blood loss is the most common cause of anemia, particularly iron-deficiency anemia. Blood loss can be short term or persist over time. It can be caused by heavy menstrual periods, bleeding in the digestive or urinary tracts, surgery, trauma, or cancer.
