World Hematology 2018 is here with a mysterious information which is something strange to hear, Blood as a meal!!!!!
We have heard stories about
vampires and have seen movies showing vampires feeding on human blood.
today lets see what happens when blood is consumed orally…
In very small amounts and if the blood is free from pathogens,
blood might not harm you. But blood when drank is toxic. When confined
to places where blood is supposed to be — such as the heart, vessels,
and so on — it is essential for life. But when ingested it’s a very
different story. Of course all toxins have doses, and just as a tiny bit
of poison won’t necessarily harm, the more we eat or drink, the
greater the danger.
Since the blood is rich in
iron and because the body has difficulty in excreting excess iron, any
animal that consumes blood regularly runs a risk of iron overdose. While
iron is necessary for all animals, in high doses it can be toxic. This
condition is called haemochromatosis which
can cause a wide variety of diseases and problems, including liver
damage, fluid build up in lungs, dehydration, low blood pressure and
nervous disorders.
Unlike humans, the bodies of
animals that digest blood have adapted specialized digestive mechanisms.
According to Katherine Ramsland book, “The Science of Vampires”, the
vampire bat, “requires an enormous intake of iron, which helps make
hemoglobin for carrying oxygen from the lungs to the body tissues. Yet
the iron intake is generally higher than what the bat needs, so it has a
special process for secreting the excess. When ingested, the blood goes
through a tract that’s adapted for extracting nutrients. Research on
this system suggests that bats have a mucous membrane along the
intestinal tract that acts as a barrier to prevent too much iron from
getting into their bloodstreams.”
Since humans did not evolve such an iron-extracting mechanism, drinking blood can kill us.
