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.
Early symptoms of anemia might include a general sense of tiredness, or fatigue. A mild-to-moderate B-12 deficiency could also cause some shortness of breath, a feeling of nervousness and possibly diarrhea. deficiency is rare in healthy young people, but isn't uncommon for older people with poor diets. Some individuals with a mild deficiency might have no obvious symptoms, but because vitamin B-12 is essential for the production of new red blood cells, mild anemia may occur with a low intake of this vitamin.
