Biotechnology, a '90s buzzword, popularly conjures up somewhat
ominous images of gene-tinkering. Yet manipulating the genetic
makeup of plants and animals to improve crop yields is far from
new. Cross-breeding for desired traits such as tallness, greater
milk yield or sweeter fruits, has been practiced ever since
humans took up farming. However classical breeding methods have
drawbacks, especially the length of time required to achieve the
desired quality. Traditional cross-breeding means crossing all
the genes in two plants or animals for maybe 10, 12 or more
years, to create one with the desired trait(s). Also,
traditional cross-breeding can only be used within individuals
of the same (or related) species - further limiting its ability
to enhance or alter food quality.
What are the benefits of biotechnology? And are they, really?
Biotechnology can dramatically reduce the time and effort
required to improve crops and livestock. The technique allows
scientists to modify plants and animals in a more controlled
way, choosing selected genes for cross-breeding instead of
crossing hundreds of genes through many generations to obtain
the desired characteristic. The new technique allows the
transfer of one or a few selected gene at a time, for just one
or a few desirable traits. And the technique even permits genes
with certain traits to be transferred from one species to
another, impossible by traditional breeding methods.
The basis of modern food biotechnology depends on the molecule
deoxyribonucleic acid or DNA, the genetic material of all living
cells. It is contained in the chromosomes (threadlike
structures) inside the cell nucleus. Unravelling the molecular
structure of DNA opened the door to rapid advances in food
biotechnology. instead of mixing all the hundreds of genes
within a plant or animal in back-crossing, scientists can now
"select out" a particular gene (length of DNA) responsible for a
particular trait. In essence, genetic manipulation means taking
one or more selected genes (portions of DN) and incorporating
them into the genetic material of another plant or animal,
bypassing the need for tedious years of breeding. The gene
transfer is done by a complex "cut and paste" procedure in which
transcription or cutting enzymes "cut" (remove) a specific gene
from one organism's DNA and "paste" or splice it into the DNA of
another organism.
The burgeoning benefits of food biotechnology include better
tasting fruits and vegetables, disease-resistant crops requiring
less pesticides and plants with improved nutrient contents, to
name a few. See the conclusions at the end before you become
overjoyed with these “improvements”.
For instance, slower-ripening tomatoes that can stay on the vine
longer without rotting, will allow better-tasting ripe produce
to be shipped out instead of being artificially ripened. Or, for
example, crookneck squash plants can be made resistant to the
viruses carried by insects (aphids) that often destroy them,
reducing crop spoilage and decreasing the need for pesticides.
Growers are also producing virus-resistant varieties of
potatoes, cucumbers and melons. See the conclusions before you
get too enamored of the possible benefits seen here.
Other improvements achieved through food biotechnology are sweet
potatoes resistant to the "feathery virus," higher-protein rice
(obtained via genes transferred from pea plants) and cooking
oils with lower saturated fat contents. Corn, canola or soybean
plants can now be modified to reduce their saturated fat content
- thereby perhaps helping consumers to lower their
blood-cholesterol levels. Gene transfer is also used in animals
to make them resistant to specific diseases and to meet consumer
demands for leaner meat.
Stringent regulations ensure the safety of biotech techniques –
True or False?
Health Canada, Environment Canada, Human Resources Canada,
Fisherlee and Oceans along with Agriculture and Agri-Food Canada
jointly regulate the products of biotechnology. They assess
health risks before products made by biotechno10gy are allowed
on the market. These agencies ensure that human and animal
health and the environment are not harmed. In Canada today, the
only approved use of biotechnology for food production is for
chymosin produced through recombinant DNA techniques.
Chymosin, known as the "animal-friendly cheese enzyme" is far
cheaper and easier to produce by biotechnology than its
predecessor rennet, which had to be extracted from bacteria in
the lining of calves' stomachs (Almost half the cheese made in
North America no longer requires rennet – but there are
complications beyond normal ken with this process, so make sure
you know the whole story).
Also under consideration by Canada's regulators is an
application by the Canadian dairy industry to use bovine
somatotropin, or BST, to increase milk production. BST, a
protein hormone needed by cows to produce milk, can now be made
outside the cow's body through recombinant DNA techniques, then
put back into cows to enhance milk production. This could be a
very dangerous process.
In conclusion – beware.
Given that the world's present population of nearly 6 billion
will double to nearly 12 billion by the year 2030, one would
think right away that anything that can help food production
keep pace should be welcomed. Never-the-less, the advent of gene
modification techniques gave us several GMOs including most
notoriously Soy.
The Soy GMO has, in the first 10 short years, contaminated
virtually the entire world’s crops of Soy, to the point where
there is practically no uncontaminated Soy stock left anywhere.
The possibilities of “Certified Organic Soy” are virtually
nonexistent. Similar problems are arising with other GMO grains
around the world.
Two problems seem to arise from genetic modifications. While we
have increased production of grains, helping to meet food
shortages with increasing populations, digestive disorders
abound with the new grains and cross-polinization with
unmodified stocks is slowly contaminating the world’s crops of
“natural” grain stocks.
Our governments seem to be hiding these known, published and
publicized results of GMO activities. One thing is certain right
now: the producers of Bio88+ (Plus) use only the very finest
“certified” organic components in the making of their highly
nutritious food product. In itself it provides virtually all of
the added nutrition, in the form of vitamins and minerals, that
you need in your diet in order to maintain excellent health.
Bio88+ (Plus) is produced in a government supervised laboratory
using an ancient Native North American fermentation process.
