A response to common misconceptions of GE foods
Posted by Nigel Tunnacliffe under Food , Genetic engineering[15] Comments
A blogger recently commented on a post from March, and while I replied to the comment, I don’t think that enough people are going catch my response. To bring this discussion forward, I will respond to Karl from Inoculated Mind here.
Karl: “The sugar that results from the GE sugar beets is identical to the sugar from non-GE beets. You’re giving yourself unnecessary food-fear hurdles.
Do you think that mixing DNA from different species is unnatural? Would it interest you to learn that Sugar Cane is a mixture of two different grass species, a polyploid? A whole host of other crops that we eat are polyploid, and have had their genetics modified drastically.”
Nigel: You have raised the most common misconceptions from the pro-GE community, which makes my response easy. First of all, it is impossible that sugar from GE beets would be identical to sugar from non-GE beets. if that were the case, one would not be able to design a test that would identify GE sugar. GE crops have novel DNA, and novel proteins. No tests are done to identify all of the novel proteins, and adding these types of proteins into people’s diets could cause serious issues if they turn out to be allergic.
Second of all, conventional breeding and even hybrid breeding combine genetic material from plants that are in the same family or at least the same species. Genetic engineering can introduce genetic material from plants/animals/microbes/fungi that are in a different kingdom. It has been demonstrated that a genetic code will produce a different protein if it is in bacteria or in a plant, yet test are not done to determine the effects of this new protein on humans, or even animals. The genes that have been introduced into sugar beets are taken from the only bacteria able to survive in the tailings of a Monsanto herbicide factory.
Finally, it should not be for you to say that I should eat genetically engineered food. That should be my decision. Smoking was not considered unhealthy in the thirties and fourties, but people still had the choice as to whether they would smoke. We now know that smoking is carcinogenic. Furthermore, we now know that second-hand smoke is carcinogenic, so even non-smokers can get smoking related diseases. There is no conclusive evidence that genetically engineered foods are carcinogenic, yet there is also no conclusive evidence that genetically engineered foods are not carcinogenic. I would rather not take the chance. If we find out thirty years from now that GMOs are cancer-causing, I think everyone would rather have stayed away from them.
I always welcome comments from the pro-GE and the anti-GE communities. Please feel free to post a response.
