Eating blood can replenish blood.

The main component of blood cells is red blood cells. One of the main factors affecting red blood cell production is iron.

There are two types of iron provided by food: one is iron from animal foods - organic iron, which is easily absorbed by the human body and is not interfered by other substances in food. The main source is Animal whole blood, animal liver and meat, etc. Therefore, it is said that eating blood has a good effect in replenishing blood.

The other is iron from plant foods - inorganic iron. Its absorption is easily interfered by phytic acid, oxalic acid and dietary fiber in food, and the degree of absorption is very low. Iron deficiency can easily lead to iron deficiency anemia. One of the dietary methods to prevent and treat iron deficiency anemia is to eat animal whole blood, animal liver and lean meat from time to time. Moreover, generally speaking, the iron absorption rate of animal foods is relatively high, about 20%.
