Are GMO Foods Safe To Eat?
Posted By Wellness Club On January 16, 2009 @ 6:36 pm In Health Freedom,Nutrition and Health,Opinion | No Comments
Many people don’t even know what a "GMO food" is, much less whether or not such food is safe to eat. GMO stand for "Genetically Modified Organism," and the truth is that you are almost certainly already eating GMO foods without knowing it because there are no label requirements for manufacturers and growers to list GMO’s in food. Since these foods are already in our daily food supply, shouldn’t we understand something about the "pros" and "cons" of their use?
Let’s take a look at what "GMO" is all about.
Genetically Modified Organisms are plants or animals that have been "genetically engineered" to contain genes from an entirely different plant or animal. The resulting organism is called transgenic or GMO (genetically modified organism).
Genetic engineering is different than traditional cross breeding, where genes can only be exchanged between two closely-related species. In genetic engineering, genes from completely different species are inserted into each other. For example, scientists in Taiwan have inserted jellyfish genes into pigs in order to make them glow in the dark.(1) My pondering: why do we need "glow in the dark" pigs?
The Extent of GMO Foods in the U.S. Food Supply
It is legal for farmers in the U.S. and a very few other countries such as Argentina to produce and sell GMO foods for human and animal consumption without making mention of this on the label. In other places including Europe and Japan, GMO foods are banned until adequate testing confirms that they are safe for human consumption and for the environment. Currently, approximately 70% of all processed foods in American supermarkets contain GMO ingredients.(2) Genetically engineered foods that have been approved for consumption and are already in current use include alfalfa, cherry tomatoes, chicory, corn, cotton, flax, papaya, potato, rapeseed (canola), rice, soybeans, squash, sugar beets, and tomatoes.(3)
Why Manufacturers Favor GMO Foods
On the "pro" side of the GMO question, manufacturers argue that genetically modified crops can be bred to resist disease or damage from chemicals, thus making harvests more stable. Most genetically engineered crops grown today are bred to be resistant to herbicides and /or pesticides so they can withstand the rigors of weed killer without being killed. Proponents claim that genetically engineered crops use fewer pesticides, but in reality GE plants often require more chemicals than non-GE crops.(4) The reason this occurs is because weeds grow resistant to pesticides, requiring higher levels of weed killer to subdue them. Because the GMO food-crops are resistant to higher doses of herbicides, the higher doses can safely be used without killing the food plants. Naturally, this exposes the food crops to higher levels of chemicals, but because the GMO crops are resistant, they are not killed. Instead, they wind up in the grocery store, often containing significantly higher levels of the chemical toxins they have been bred to withstand.(5)
This resistance of GMO plants to chemical toxins works so well that some GMO crops are actually classified as pesticides. For example, the New Leaf Potato was genetically engineered to produce Bt (Bacillus thuringiensis) toxin in order to kill any pests that attempted to eat it. This potato was designated as a pesticide and as such was regulated by the Environmental Protection Agency (EPA), not the Food & Drug Administration (FDA) which regulates food. Safety testing for these potatoes was not as strict as with food because EPA regulations had never anticipated that people would intentionally consume pesticides as food. These GMO "not intended as food" potatoes did in fact make it into grocery stores (they have since been taken off grocery store shelves), but this case underscores how GMO foods whose safety is unknown can make it into our "protected" food supply. (6)
Most of the GMO produce is approved for human consumption, even without your knowledge of what it is or that you are eating it.
Potential Dangers of GMO Foods
One of the biggest concerns over GMO foods is simply that their safety has not been tested. The science of genetic engineering is relatively new, and we simply do not know what effects can result from putting DNA of one species into another species. The practice might prove to be safe. On the other hand, we may be creating incredibly dangerous "Franken Foods" and "Franken animals," the long-range effects of which are entirely unknown and little-studied at this point. Opponents to genetic engineering state that GE foods must be proven safe before they are sold to the public and I must agree.
Potential problems that could arise with genetic engineering include:
How to Avoid GMO Foods
Until more is known — or until ANYTHING is known — about the safety of GMO foods, those who want to steer clear of GMO-containing foods can do so by following these steps:
GMO "Factoids"
My Ten Cents Worth on GMO Foods
The unsuspecting public (that’s you and I, folks!) are continually acting as guinea pigs for everything from foods and drugs to environmental chemicals and cosmetics. AND SO FAR, THE TRACK RECORDS OF THE SAFETY OF THESE ITEMS DOES NOT FAVOR THE PUBLIC. Personally, I don’t like being forced to "test" the safety of every new chemical, drug and "technique" that Big Industry dreams up without my consent. Isn’t this what, ostensibly, the FDA, the USDA, the EPA and other government-acronymed groups (GAG’s) are supposed to be protecting us from? Yet you and I are still exposed to hazardous chemicals and techniques that are "approved" before their safety is truly verified. I don’t know about you, but I’m not happy about this.
I take good care of myself. Why should I let the government use me as a test subject for so many potentially dangerous chemicals and now (perhaps even worse), gene-splicing experiments? Until I have proof that me, the honeybees (11) and the environment are safe from GMO crops, I’m going to stay as far away from them as I can. I believe we should be more circumspect about what we are creating, and the safety of same, before we unleash genetically modified organisms on an unsuspecting public.
