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.
Iron-deficiency Anemia. A woman who is iron-deficient has just enough iron to get by, while an anemic woman doesn't have enough iron to meet her body's needs. Causes of anemia include a deficiency of vitamin B or folic acid, an ulcer, hemorrhoids, other internal bleeding. Once iron stores are depleted, it can take anywhere from a few weeks to 6-12 months for them to be restored depending on the severity of the anemia.
