* [[Anemia]]. Anemia is one of the most common blood disorders that results to the decline of red blood cell count. Red blood cells are responsible for transporting important nutrients and oxygen all throughout the body.

Iron, which can be found in bananas, can help regulate these red blood cells. Bananas contain relatively large amounts of iron which helps in the production of RBCs and in stimulating the growth of hemoglobin in the body which can help in cases of anemia.
