to absorb non-heme is much more effective.
Nonetheless there are other essential diet
elements like calcium that inhibit the
absorption of non-heme iron hence non-heme
iron is fundamentally less preferable for a
healthy diet. The B12 vitamin is a different
matter though as, although it is an essential
vitamin for a healthy diet as it is vital for bone,
blood and nerve cell formation along with other
processes, it is not created in vegetables or
animals, but by specific microorganisms that
live in the soil. Before the discovery of the
existence of microorganisms in sixteen sixtyfive
by Robert Hook and more specifically germ
theory a bit later, most vegetables came with
these microbes however since the realisation
that a few of these microbes caused diseases
there has been much more of an effort to
remove or sterilise all vegetable products which
has meant, for a quite a long time, most of the
sources of B-12 could only be found in animal
products such as meat and dairy.
