Genetic engineering is a scary subject.
It summons up images of mutant beings from science fiction movies. But when it applies to your food it should
not be a concern. Some argue that
consumers have a right to know what goes into their food and are requesting
that genetically engineered products be labeled as such. Is this really a push to inform or a push to
scare? Center for Food Safety promotes
this concern with general claims of dangers and warns, “Congress
has yet to pass a single law intended to manage them responsibly.” On the other hand, the FDA presented to the House Committee on Science reasons why there is nothing to worry about. In their conclusion, they emphasize that the
current review process “allows us to ensure the safety of new food products and
also allow the use of safe, new biotechnology techniques that give
manufacturers the ability to produce better products and provide consumers
additional choices.”
When dealing with such issues, it is important to deal with facts. Just as I did with the
fiscal cliff posting where I showed graphically how current spending practices would
lead to a progressively worse situation, and how this new trend arose only in
the last decade; here I want to pass along some reliable information on genetic
engineering of the food supply to reinforce the FDA's position.
I recently read Botany for Gardeners by Brian Capon. It contains this excellent explanation on the topic
(pp. 143-144). Mutations
occur naturally within plants. Sometimes
it harms the plant. Sometimes it has no
discernible effect. Sometimes it is
favorable and makes the plant more hardy, flavorful, attractive, or
nutritious. Formerly scientists had to
use crossbreeding and other techniques to try to isolate and preserve favorable traits. It was a slow, hit-or-miss
process with only a small fraction of successes. “The most direct method of obtaining plants
with more desirable characteristics would be to directly transfer genes that
control these features…thereby avoiding the uncertainty of cross-breeding.” Although the main concern about genetic
engineering is harm to human health, as techniques are perfected, the danger is
no more likely than what may happen by traditional crossbreeding. Use of genetic engineering in the future promises custom-made plants that
are more resistant to pathogens and harmful insects, better able to withstand
droughts, stronger, more productive and better in nutritional (or
medicinal) value.
