With many complexities of modern life, it is easy for us to get so bogged
down in discussions of the complex issues. By focusing on the many details
surrounding them, we may forget to establish the basics and understand the
fundamentals.
Few topics are more important to consumers and equally filled with unknowns
and confusion than the subject of gmo food.
No matter how much we may think we know, science and
technology keep adding to our understanding and it is helpful to try to keep the
foundations of our beliefs on solid ground.
Hopefully this will do just that, beginning with the terminology used to
describe a set of molecular techniques that can alter the genetic structure of
organisms and transform food as we know it.
The terms usually heard are gmo and ge, short for genetically modified
organism or genetically engineered. They are used interchangeably to describe
the organisms that result from a process of inserting genes to create novel
substances that have genes from dissimilar species and could never occur in
nature.
Through this process of genetic alteration, scientists are able to take genes
from any organism, a plant, a virus, a bacteria or even a human and engineer
them into another organism to try to produce a desired characteristic.
The process occurs by extracting genes from one organism, adding a promoter,
which is generally a virus or bacteria, coating it all with antibiotics and
literally shooting the extracted gene in the form of microscopic pellets, into
another gene.
With the gmo foods, which we will focus on, the genes
are introduced into the plant tissue in a laboratory by either being coated on
tiny pellets of gold or tungsten and fired with a special gun or sometimes are
bought in via a microorganism in a way some have likened to a viral
infection.
The genes are
segments of DNA that specify the structure of proteins. The proteins are like
the building blocks. Each one has unique characteristics. Now don’t get
overwhelmed, we aren’t going to lose you in deep science.
It helps me to think of the different proteins being
combined, somewhat like a imagining a toddler playing with an assortment of
blocks. When the whole collection of different proteins is seen like different
blocks, it is easy to imagine how they can be combined in very many different
patterns to create very different results.
In much the same way the toddler will never make the exact structure twice,
there is no way of predicting where the new protein, inserted to create the
trait, will go when it’s shot into the gene. Because these alterations occur
once, in totally unique ways that can not be repeated, the resulting new
organism is termed a genetically engineered "event".
All of the plants that are produced with that trait are bred from that
original event. In nature we don’t see that type of identical replication
because nature is based on diversity and traits evolve in response to
environmental changes and crossing of traits between like organisms.
In the case of the genetically altered foods on the market, the traits
conferred are either herbicide resistance or pesticide producing abilities.
About 71% of the crops are engineered to resist herbicide, including Liberty
(glufosinate ammonium) and Roundup (glyphosate). About 18% produce their own
pesticide. And 11% do both. The ones that do both are called stacked.
The herbicide tolerant plants are also called Ht and the pesticide producing
are known as Bt for the Bacillus thuringiensis;. Most of the herbicide resistant
forms in the America’s food supply, are created to tolerate glyphosate, sold
commercially by Monsanto as their trademark Roundup® weed killer.
You’ve probably seen the television commercials, boasting that it kills weeds
for up to three months and not even the rain will stop its power. The same
stuff, but about six times stronger, is soaked on the crops. Everything but the
gmo resistant plants die; they’re created to resist that one herbicide.
The seeds are sold as Roundup Ready® or RR-soy, RR-corn, RR-cotton,
RR-canola, etc. They are patented and registered by names like MON863 or NK603,
but since they all resist the Roundup herbicide they are all called Roundup
Ready® crops.
These genetically altered varieties now make up about 90% of America’s soy,
about 50% of the corn, canola, cotton and lesser amounts of other crops
including papaya, squash, potatoes and others depending on the year.
Genetically engineered events often have names to identify the company that
holds the patent as in MON for Monsanto. Others indicate the herbicide they
tolerate. That’s the case with Bayer’s LL601 rice, the source of a widespread
accidental contamination in 2006 that had other nations pulling US rice off the
shelves, as we were hearing about e-coli spinach.
So much for America’s corporate media.
The LL601 was created to have a tolerance to an herbicide called Liberty Link
made by Bayer Crop Science. The designation LL helps growers match the altered
seed with the herbicide or pesticide it is grown with. It’s not so yummy to
think of LL601 Rice Krispie Bars or Frosted MON863 Corn Flakes but that’s what’s
in much of it here in America where the gmo crops are unregulated and
unlabeled.
Beyond the idea that the names aren’t exactly a marketing departments dream,
these genetically altered events have special properties that are important to
talk about. Now the industry claims that changing a single gene isn’t
significant and in the case of foods it doesn’t change the traditional varieties
in ways that affect us when we eat them.
There is both serious science and feeding study results that suggest quite
the opposite.
In some ways common sense tells us that to change the basic genetic code that
has evolved over the course of the history of life on the planet, to produce
characteristics in plants where they tolerate toxic herbicides or make their own
pesticides to kill the bugs that eat them, is not quite the same as a food that
has evolved to nourish the planet’s life forms. But there is science to cite so
we’ll move along to that.
We know now that genetic modification requires the insertion of foreign
genetic material into the gene of the plant. In the case of gmo foods they
accomplish that with a promoter which is generally an antibiotic resistant
marker and the entire thing is then coated with an antibiotic.
That creates cause for concern on several levels. As we know Nature is based
on evolving and all organisms, including the human body is designed to mutate in
response to threats encountered. Our internal operations are much like a
microcosm of the global ecology. Our immune system needs to identify the
proteins that are threats and attack them.
Genes are ecologies too, they work in conjunction with one another to build
defenses against natural attackers. When we introduce new genetically modified
substances they posses new proteins. These are novel substances in the plant and
they are substances our bodies have never encountered in nature.
The new proteins are also alien to the plant. When
those plants then interact with the entire ecosystem and the human body, nature
is faced with challenges that evolution has never prepared for. In a worst case
scenario these novel proteins may be toxic. In a lesser extreme they can trigger
allergic reactions or other immune system responses.
The body identifies the novel substance as a foreign
substance that it does not recognise as a food. The numbers of reactions an
immune system can have to this foreign protein are as varied as the varied novel
proteins and as the individuals.
Just as one person may be allergic to peanuts and
another has no problem eating them, the proteins that generate an immune
response, and what that response is in terms of severity and body reaction,
varies as much as we do. It goes back to the basic divirsity of nature and the
fact that no two living organisms are exactly alike.
One person may get a rash while another gets breathing
problems from an allergic reaction to an identical item of conventional or
natural food. The protein that triggers the reaction is the same but the
individual immune system responses are different.
We do share many traits within species though. That’s
when numbers come into play and we begin to see paterns of reactions. For
example we look for a spike in the number of individuals who are afflicted with
a given ailment and try to find a common source for the problem.
In the case of the genetically altered foods and patterns resulting from
those we would look to the US as a test group. Since we have been eating these
for a decade indicators of allergic reactions would manifest in rising food
allergies or increased rates of other auto-immune diseases.
Then there are the groups of side effects that
would show antibiotic resistance that may suggest that the novel gene proteins
have mutated the antibiotic promoters. Or there may be problems with the
digestive tract, suggesting the Bt inserted to kill a bug that eats the plant,
is similarly attacking the gut of humans who eat the bacterium with
regularity.
If we look at the television commercials for treatments it would seem that
many of the allergies and ailments are growing right along with the volume of
these crops in our diets.
Despite the claims of industry they have not been subjected
to safety testing and the companies who create and grow them do not have the
support of the medical community.
These were introduced by the petrochemical companies with claims that there
was no basis for concern and no reason to test for novel proteins or track human
health effects. No premarket testing was done and no post market follow up was
put in place to record health effects.
At a very minimum it should be a subject of serious medical investigation and
a right of every consumer to know what we are eating. For more detailed
discussion of the modification process and the health issues this Dr.E. Cullen
has done a brilliant job in this month’s Irish
Medical Journal has one of the best articles I’ve ever read, written in a
way anyone can understand.
These gmo crops began as a business plan aided by political policy and now it
is time to put them on the agenda as a public health issue. After all we are
what we eat and our health and the health of our families and children is
priceless.
We as consumers, especially here in America, have the power to to stop the
feeding experiment by avoiding corn, canola, soy, white rice or papaya that are
not certified organic. We can end the toxic policies that have allowed our
Nation to be fed a Roundup Ready diet.
Knowledge is power. Become informed and involved. Call your Members of
Congress and tell them it’s your right to choose what we eat and take the blank
check from the chemical companies off the table. Put pure food on the National
priority list.
One by one, day by day and acre by acre we will regain the gifts of Nature
and health that comes from pure food, water, air and environment for our
children.
Capitol Switchboard 202-224-3121 and be polite but firm; the Congress works
for you.
