What does drinking blood do to the human body?

Answer:
It does nothing to the human body. Drinking blood is a powerful source of the mineral Iron and is still practiced in many countries. Blood is the primary ingredient in Blood Sausage and other common foods.

subsisting WHOLLY on blood, though, would be inadvisable, since it has little nutritional value.
