Are GMO foods really all that bad? Is the concern all just a bunch of environmental paranoia?
First of all, I used to be pretty neutral to GMO, but, after reading about it what it really entails, I have no hesitation in labelling it both nasty and toxic. So, yes, GMO is bad – really bad. I would never serve it to my kids and I avoid it like the plaque myself now and below I’ll give you many studies showing you just why I am so emphatic about the subject. And for the record: in my opinion, what has been done with GMO products shows the very worst in American corporate ethics and philosophy and it shames me to think that I have done so little to oppose it.
But before we even go into how toxic and deceptive GMO foods appear to be, I want you to step back and think of something very important: good, quality food is our #1 arsenal against chronic disease at this point. That’s right: I think that proper diet and nutrition can heal the majority of our health problems and I know many of you do as well. So, if you believe that food is our last bastion of health, why would we let a bunch of mad scientists go in there and alter the genome of all our most precious crops?!? Well, we shouldn’t as I’ll show you below.
Again, check out these 12 Studies that (Likely) Show GMO is Deceptive and Dangerous:
1. GMO Gate, Part I (The Pustazi Study). What happens to a researcher who finds issueswith GMO crops? Simple: he is fired immediately. This is exactly what happened to Dr. Pusztai after the explained on public television that his study on GMO potatoes resulted in intestinal damage to lab rats. Basically, the lining of their stomach and intestines thickened from the stuff. He even went on to say that he would never feel it to his kids.
Well, good for him! But instead of receiving praise for protecting the public welfare, he was fired from his post at the Rowett Institute and was censored by the government. Yes, the GMO players, which include some of the largest corporations in the world (Monstanto, Dupont, etc.) are powerful! Fortunately, the following year the prestigious journal Lancet was willing to publish some commentary – kind of an open discussion about his research at least. 
The scientific community was appalled by this censorship and it was noted that:
“Their memorandum stated (the following is largely verbatim from the WSWS website): “Those of us who have known Dr. Pusztai’s work or have collaborated with him, were shocked by the harshness of his treatment by the Rowett and even more by the impenetrable secrecy surrounding these events. It is an unacceptable code of practice by the Rowett and its Director, Professor James, to set themselves up as arbiters or judges of the validity of the data which could have such a profound importance not only for scientists, but also for the public and its health.” The memorandum concludes, “There is no doubt in our minds that the reviews will remove the stigma of alleged fraud and will restore Dr. Pusztai’s scientific credibility.” One of the scientists who reviewed Pustzai’s work, Dr. Vyvyan Howard, foetal and infant toxico-pathologist at the University of Liverpool, told the World Socialist Web Site, “I am working on some features of lectin toxicity and that is how I came to know Arpad Pusztai, who is certainly one of the world’s experts in this field.”” 
NOTE: I urge you to visit his personal site here and check out his commentary.
2. GMO Gate, Part II. (The Seralini Affair). One “trick” that company-paid researchers do is to keep animal studies nice and short. My understanding is that Monsanto and other GMOers always stop the study at 90 days as a protection. Well, one research did what should be done in every case and ran a rat study out to two years. What he and his colleagues found was horrific:
“Biochemical analyses confirmed very significant chronic kidney deficiencies, for all treatments and both sexes; 76% of the altered parameters were kidney-related. In treated males, liver congestions and necrosis were 2.5 to 5.5 times higher. Marked and severe nephropathies were also generally 1.3 to 2.3 times greater. In females, all treatment groups showed a two- to threefold increase in mortality, and deaths were earlier. This difference was also evident in three male groups fed with GM maize. All results were hormone- and sex-dependent, and the pathological profiles were comparable. Females developed large mammary tumors more frequently and before controls; the pituitary was the second most disabled organ; the sex hormonal balance was modified by consumption of GM maize and Roundup treatments. Males presented up to four times more large palpable tumors starting 600 days earlier than in the control group, in which only one tumor was noted. These results may be explained by not only the non-linear endocrine-disrupting effects of Roundup but also by the overexpression of the EPSPS transgene or other mutational effects in the GM maize and their metabolic consequences.” 
Notice that the males were attacked the most fiercely by this product! Now what do you think happened when this study was published? Yes, all hell broke loose – pardon the expression but that’s the best term – and the journal finally retracted the paper under pressure. You can actually see the restracted paper here!
Fortunately, we can actually read the paper for ourselves and you’ll see that the paper was very careful and just stated that more study work needed to be done. It was very fair and balanced and did not make inflammatory comments. In spite of that, the paper was forced out and, fortunately, there was a huge backlash from scientists around the globe objecting to the censorship of this fine paper. If you have doubts that Monsanto, Dupont and other GMO players are weak and without power, guess again!
3. Bt Toxin Corn is Allergenic. For those who do not know, researchers (at Monsanto) genetically altered a corn to produce an insecticide called “Bt toxin.” Those ingesting the corn ingest this Bt toxin. The concept is that this toxin attacks the skeleteons of insects, thus acting as a pesticide, and yet does not affect humans. Of course, I think this vast majority of people would think that it was ethically deplorable to engineer a plant that we consume to produce a pesticide of any sort. Yet this is exactly what was done and with very little testing.
As one might expect, problems have abounded. How often have we been told that a pesticide is safe only to find out ten years later that it was damaging us and our children? (See my link on Testosterone and Pesticides for some examples. Academics have pointed out that GMO corn is associated with increased allergic reactions. Professor Joe Collins has done a fantastic job of summarizing research that shows that this kind of corn is 
- Nutritionally different (in amino acid content) than regular corn
- Increases allergies in farm workers
- Increases immune response in lab studies
- Increase igE antibodies in lab assays.I don’t know how to say it polititely, so I won’t. “Keep that ____ off of my dinner plate!” That’s how I’d word it and I’ll let you insert the noun of your choosing in the blank there.
- 3. Liver Function and Aging. GM Soybean was found to negatively alter liver properties in study of mice. Researcher concluded that:”Previous studies on hepatocytes from young female mice fed on GM soybean demonstrated nuclear modifications involving transcription and splicing pathways…Several proteins belonging to hepatocyte metabolism, stress response, calcium signalling and mitochondria were differentially expressed in GM-fed mice, indicating a more marked expression of senescence markers in comparison to controls. Moreover, hepatocytes of GM-fed mice showed mitochondrial and nuclear modifications indicative of reduced metabolic rate. This study demonstrates that GM soybean intake can influence some liver features during ageing and, although the mechanisms remain unknown, underlines the importance to investigate the long-term consequences of GM-diets and the potential synergistic effects with ageing, xenobiotics and/or stress conditions.” 
The researchers are very unemotional in their commentary as they should be, but all I can say is: you only got one liver!
4. Potential Heart, Adrenal, Spleen and Adrenal Dysfunction. Seralini of the famed “Seraline Affair” mentioned above came back full force with a study comparing the three currently popular GMO corn varieties out in the marketplace. He found many issues with all three of these maizes and wrote: 
“We present for the first time a comparative analysis of blood and organ system data from trials with rats fed three main commercialized genetically modified (GM) maize (NK 603, MON 810, MON 863), which are present in food and feed in the world. NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation. MON 810 and MON 863 are engineered to synthesize two different Bt toxins used as insecticides…Our analysis clearly reveals for the 3 GMOs new side effects linked with GM maize consumption, which were sex- and often dose-dependent. Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn.”
Can a technology get any uglier than that? I mean let’s just throw a bunch of uranium and plutonim in our kids’ breakfast cereal while we’re at it, right?
5. Interestinal Cancer? A study of GMO potatoes showed “hyperplastic cell growth” in the intestines of mice. This is basically the early warning signs of potential cancer, i.e. abnormal cell growth in the intestinal walls. Researchers wrote:
“Although mild changes are reported in the structural configuration of the ileum of mice fed on transgenic potatoes, nevertheless, thorough tests of these new types of genetically engineered crops must be made to avoid the risks before marketing.” 
C’mon, guys! You man enough to eat those?
6. Stomach Lesions. Many of you will have heard of the famed FlavrSavr tomato. Well, did you know that some research showed a shocking amount of stomach lesions in mice? 
CONCLUSION: There are actually many more studies and expert testimony that show issues with GM foods. The bottom line is that these foods likely can cause many, many health issues, especially in the liver, kidney and GI tract. This is NOT something that has been adequately tested and there is ample evidence that they are dangerous.
And, seriously, it makes sense. If you go into the forest, can you just start munching on any plant out there? Of course not! Only a few plants are safe for long term consumption and logic dictates that you cannot take one of the few plants that work as foods and crops and start chaning it willy nilly or you will corrupt it into a dangerous, inedible plant.
So, yes, I am done feeding that stuff to my kids!
