Genetically Modified Foods

  1. Jan 21, 2009 #1
    Hello. I am new to this forum and am finding it to be a fantastic resource of information and people. So thankyou :).

    I am interested to get your take on what you think about the risks/benefits of G.M foods/crops. The thing that has me concerned is the fact that no long-term human study has been conducted on it's effects and secondly I am concerned about the fact that live cancer viruses are present in (most of) the G.M crops (Cauliflower Mosaic Virus). Also what if this genetic alteration is causing all sorts of problems to our DNA that could affect future generations (not necessarily us at present).



    Thanks guys, and I'm looking forward to your opinions.

    prime-factor :)

    Re: Genetically Modified Foods and Fluoride

    Can you cite a peer reviewed paper that links CaMV to cancer onset? Or are you basing your assertion on the statements of cottage industry scare groups and crackpots looking to discredit GE biomass?

    Merely because CaMV may have been used in the modification of plant DNA does not in and of itself mean that it remains present within the plant once the DNA itself has been set for germination and the host matures into its potential. Since CaMV is naturally occurring and is present in rather considerable percentages of naturally cultivated cruciferous crops, it would seem that homo sapiens has been subjected to CaMV for a rather large number of millennia of natural selection.

    For dangers of Fluoride and its connection to Communism, see the movie Dr. Strangelove.

    Good luck.

    They are good points.
    Researching the topic a while back I favourited this site:
    http://www.organicconsumers.org/ge/mwhoviral.cfm

    It has some excellent information even though it is quite old.

    But I ask this: Does it not seem unethical/unsafe to treat the population as a guinea pig for mass genetic modifications of foods and crops.

    I just raise the point that there is no long-term study to prove that it is safe for human consumption. People have also reported better health/well-being fro eating organic foods (unmodified). It just scares me that this is being done without being first proven to be safe.

    I will watch Dr. Strangelove soon :) . But do you agree that fluoridation it is forced mass medication, and even though it has been proven to be unsafe it is still being forced upon people (unless you fork out the money for expensive filters or buy bottled purified water)?

    Lots of benefits, few if any risks. We have, after all, been eating genetically modified crops for thousands of years.
    Every thing we touch contains viruses. Can you cite evidence that that particular virus is capable of infecting people?
    GM food has it's dna modified - it doesn't modify your dna. I'm not sure why you think it would.

    The websites you have linked are, for the most part, spreading crackpottery.

    Thanks for the response russ_watters.

    I probably should have rephrased when I said "Also what if this genetic alteration is causing all sorts of problems to our DNA that could affect future generations (not necessarily us at present)."

    What I am getting at , is whether it has any detrimental effects that we don't know of that 'could' indirectly (or directly) affect us and hence affect our DNA. I am just concerned at the fact that no long-term human study has been conducted on GM foods that can be held to scrutiny.

    I do agree that there are many benefits of G.M foods. I in fact believe that the benefits of G.M to some extent outweight the risks . BUT that is because we haven't fully studied the risks!. I am just amazed that something so intrinsic to our lives (food) is being genetically modified and no human tests are being done apart from the mass- guinea pig test currently going on (unless you eat 100% organic-if that's possible?)

    As it was already stated - almost every plant you eat is already genetically modified. Perhaps not using the newest lab techniques, but any kind of selection and crossing that end it hybrids is in fact genetical modification. That in turns means that we ate GM foods for the last several thousands of years. Hardly something really new on our tables.

    When we are all stood shoulder to shoulder drowning in our own dross, we will need every advantage science can give us.

    I am afraid that this thread doesn't meet criteria for a scientific discussion. Articles to unverified sources are not valid. We need actual medical peer reviewed studies.

    Re: Genetically Modified Foods and Fluoride

    There is a lot of misinformation and misunderstanding in this thread. First, the CaMV promoter is used in genetic engineering, not the virus itself. Apparently there is a recombination hotspot in the vector, which would allow it to recombine with other viruses. I am not up-to-date with that literature. Second, the question is not about whether genetic modification is dangerous, the question is whether the current process of genetic modification is dangerous. Third, let's discuss one topic per thread (fluoride does not belong in this discussion). Finally, as said in the previous post, let's stick to reputable sources.

    Re: Genetically Modified Foods and Fluoride

    I've looked up the official correspondence on the paper that is mentioned in the link.

    Here is an analysis that was published in Nature Biotechnology Scientists avert new GMO crisis and the response of the authors Hazardous CaMV promoter?, followed by another reply.

    I hope most people here have access to the information. It would be nice if there is a plant biotechnologist here, who can comment on the latest techniques used for genetic recombination. The information is from 2000 and may very well be out of date.

    Personally I am not concerned by the technology, the paper is not supported by real data that shows any danger. I wonder whether single-copy insertions are used to make transgenic plants, using some medium-strength promoter? (I would think so)

    To Monique:

    Thank you and I appreciate the links you gave, but I cannot access them because they require a login and password :( . Are there any other ways to access these sources. They look like an interesting read and I will look into them.

    Yes. I agree that it is the 'current' process of G.M manufacture which is in question and and I also agree that a biotechnologist's input would be fantastic. I'm also glad this has been moved to biology :) . That's probably a much better place for the thread.

    You can always try google: "Scientists Avert New GMO Crisis"

    Okay. :). Looks like an interesting paper. I'll read it thoroughly this week when I'm not so tired.
