I've read that low blood pressure can be caused by a lack of sodium, and that after an "episode" in which people black out they tend to crave salt due to the deficiency in their body.
people who are anemic crave ice mainly because of lack of oxygen distribution to the body. ice contains oxygen, so that's a good explanation. moreover, i don't understand why people with severe anemia, like myself, don't crave water.
You might crave chicken but if you eat it you are not a vegetarian anymore. Try vegetarian "fake chicken".
They need blood to survive
protein.
It's possible they could have an Iron deficiency. Blood is rich in Iron.
because they need iron and blood is rich in iron
i do not think so unless the blood is not yours.without blood in your body we would ask without you what would we do?.
no wat are u stupid they are flies
Go get help on this feeling of a need for blood.
It is not vmapire bat like the mythical creature vampire. They are related in no way. Ask yourself why do i crave _______? there would be your anwser. (fill the line in with something you crave) Because it's their source of food?
Apart from the Vampire bat, which is real, vampire humans are imaginary creatures. As imaginary creatures they can crave whatever the imagineer can come up with, but a craving for human blood sets up the best story line.
Vampire bats utilize all the nutritional components of blood, not just the protein.
