Can a person only feed on blood like a vampire

The blood contains approximately 700 kcal / liter, so the average adult will need to drink at least three liters to maintain energy. However, in order to maintain normal vitamin C levels in the body, a person will have to drink another six liters of blood. Is it possible to live by eating only her?

The vampire “diet” will quickly lead to disastrous consequences, no matter whose blood a person feeds on

Unlike humans, blood-eating animals have special digestive mechanisms. For example, the body of a vampire bat processes blood, extracting nutrients from it and getting rid of excess. Blood can be toxic to humans.

A couple of teaspoons of pathogen-free blood will not harm the body, but more can be dangerous. Blood is rich in iron – a person needs it in moderate doses. An excess of iron leads to hemochromatosis, a disease of weakness, heart failure, fluid buildup in the lungs, nervous disorders, low blood pressure, and liver problems.

There is also too much salt in the blood. Three liters a day gives about four and a half times the daily value of salt. This amount will quickly lead to dehydration and kidney failure if you don’t drink enough water. If you consume water, hypertension may develop.

Is it okay to drink your own blood?

A study published in the journal Plastic and Reconstructive Surgery found that using a person’s own blood can help heal wounds and some sports injuries. However, this treatment is done with an injection. Eating small amounts of your own blood as food can lead to nausea and vomiting. A large amount will also lead to hemochromatosis.

Animal blood?

The consumption of untreated animal blood can cause infection, as various bacteria can easily multiply in it.
