LEV80 Do not eat the blood of animals or fowl. In addition to what we wrote above (Leviticus 7:23), we can suggest another reason why consumption of blood is forbidden. Besides causing physical harm to our bodies, consumption of blood promotes the negative character trait of ruthlessness. It is cruel to eat an animal's blood, for the blood is the creature’s very vitality. The Ramban writes similarly, that it is not fitting that one soul consume another. Furthermore, he writes, it is known that whatever a person ingests becomes a part of him, and if a person eats the blood of beasts he becomes coarse and animalistic, for he acquires some of their base animal nature.
