Garlic:
that oh so deliciously pungent bulb from the lily
family that has been around humankind since the invention of writing, has been valued for its
ability to spice up a
meal, whet the appetite and to help cure a host of different ailments.
Now,
today’s researchers are taking a second look at garlic and
are finding out that
it not only helps makes things taste good, it might also play a role in
preventing certain types of cancer.
Garlic and cancer
A number of studies have been done focusing on garlic’s
organic allyl sulfur components and their ability to effectively
inhibit the
cancer process. These compounds make cells more vulnerable to the
stress which
is created when cells divide. Since cancer cells divide more rapidly
than
normal cells, they are susceptible to these specific stressors. Therefore, cancer cells
have a much greater
potential to suffer damage from the allyl sulfur compounds that are
found in
garlic.

The studies on garlic have revealed that garlic’s benefits
are not limited to any specific species, to any particular tissue or
even to a
specific type of carcinogen. However, there is a strong link between
garlic and
the prevention on prostate and stomach cancers.
37 different observational studies have been done on
people exploring
the use of garlic and cancer prevention. Of the 37, 28 of the studies
have
revealed that garlic does play some role in cancer prevention.
It is
important to
note that these studies are observational: comparing the incidence of
cancer
among garlic and non-garlic consuming populations. Clinical studies are
still
needed for further verification, but unfortunately government funding
for
garlic research is limited and pharmaceutical companies are reluctant
to study
widely available plants that might have health benefits since there is
no
profit in it.
A complicated
chemistry
Garlic’s chemistry is extremely complicated and how garlic
products are manufactured and processed greatly effects the medicinal
value of
its various chemical constituents.
Peeling garlic and then turning into an oil or
powder can actually
increase the number and variety of active compounds. The peeling
process
releases the enzyme allinase and kick starts the process that leads to
the
chemical reaction that produces diallyl disulfide. Diallyl Disulfide is
also
formed when garlic is crushed or chopped, however if it is cooked
immediately
after peeling and chopping the cancer fighting benefit of this sulfide
is lost.
Some secientis have recommended that you let the garlic sit for 15-20
minutes
after it has been peeled in order to allow the allinase reaction to
occur.
