Recombinant DNA experiment in a petri dish

It has been a long-standing belief that all of the animal studies undertaken to test the dietary safety of GM grains have proven that GM grains have no negative effects on health.  There are, however, many other studies that seem to say the opposite that have failed to rise to the surface of public access.  Whether or not the involvement of monetary exchanges and politics has anything to do with that I will leave to your judgment…suffice it to say I believe it does.


Animal studies undertaken to test the safety of GM foods that are not included in mainstream science can be somewhat difficult to track down.  If you are interested in finding such studies, one of the most efficacious ways it to “follow the breadcrumbs,” so-to-speak, and read the references.  This will guide you to other resources more easily.

Before I proceed, please understand that I am aware that I am skirting on the very edges of what may be publicly acceptable when approaching the subject of GMO food research and I am perfectly comfortable with that.  You are free to leave your comments below, but I ask that you remain respectful if you are in support of GM foods.   Now, let us continue…

One of the top resources I have found that is easy to access is http://www.gmoevidence.com.  There is a surprising amount of research that has been completed on this website by scientists that are in the know about how to properly conduct a research experiment.  For the purpose of time, I am not going to summarize it all here but I will bring to the surface a handful of them.

A long-term study completed by Seralini et. al. that was conducted over a period of two years was one of the most telling of all animal studies conducted.  In this study, rats were fed a diet that contained 11% Round-up tolerant GM corn, with subgroups of corn that were cultivated both with and without Round-up.  I quote the abstract:

“The health effects of a Roundup-tolerant genetically modified maize (from 11% in the diet), cultivated with or without Roundup, and Roundup alone (from 0.1 ppb in water), were studied 2 years in rats. In females, all treated groups died 2–3 times more than controls, and more rapidly. This difference was visible in 3 male groups fed GMOs. All results were hormone and sex dependent, and the pathological pro- files were comparable. Females developed large mammary tumors almost always more often than and before controls, the pituitary was the second most disabled organ; the sex hormonal balance was modified by GMO and Roundup treatments. In treated males, liver congestions and necrosis were 2.5–5.5 times higher. This pathology was confirmed by optic and transmission electron microscopy. Marked and severe kidney nephropathies were also generally 1.3–2.3 greater. Males presented 4 times more large palpable tumors than controls which occurred up to 600 days earlier. Biochemistry data confirmed very significant kidney chronic deficiencies; for all treatments and both sexes, 76% of the altered parameters were kidney related. These results can be explained by the non linear endocrine-disrupting effects of Roundup, but also by the overexpression of the transgene in the GMO and its metabolic consequences” (highlights are mine).

As you can see in the text I have highlighted red, there was an increase in breast cancer and pituitary dysfunction in female populations of rats, and increased liver necrosis (death), kidney disease and kidney tumors in male rats.  There was huge endocrine disruption in both sexes partly due to the Round-up chemical itself, but also due to expression of the genetically modified gene in the corn itself in the body of the rat.

This brings me to the question…how many people to you know that have  or have had breast cancer, polycystic ovarian syndrome, pituitary imbalances, liver disease that was not caused by toxic substances, and kidney cancer or failure?  I have known several and the occurrence continues to rise.  It seems that seemingly healthy people are being diagnosed with breast cancer, and I find myself wondering if the GM food that we are all consuming is causing the expression of genetically modified genes from the food we eat in our own bodies that is creating hormone disruption and causing cancer, based on the findings of the study above.

256px-more_pigletsAnother study that raises a cause for concern in my eyes is one by Dr. Judy Carman.  She conducted a study using pigs, comparing groups fed a GM diet of corn and soy with a group that was fed non-GM corn and soy.  Pigs have a
digestive system that is very similar to that of humans, so the outcomes of such a study are more directly applicable.  You can find the summary here; but to summarize for you, the group that was fed GM feed showed severe stomach inflammation upon autopsy findings.  This is following the observations by investigators that noted there was a reduced ability to concieve, higher miscarriage rates, observable intestinal problems such as bleeding ulcers and death of the animal via hemorrhagic bowel disease (internal bleeding to the point of death), among other things.

Again I reflect on this and consider how many women I know that have had unexplained miscarriages and the inability to conceive despite trying even the strongest interventions, like IVF.  And digestive issues!  We all know people that have been diagnosed with irritable bowel syndrome, Crohn’s disease, bleeding ulcers and long-standing stomach aches with no apparent cause.  Does this make you wonder?

There are many arguments as to why animal research is not applicable to human outcomes.

  • One is that animal physiology is different than human physiology so we cannot compare them.
    • My response: while this is true, the end result of any digestive process is break-down and assimilation of the food that is ingested.  Whether that happens in one step or ten, the end result is the same.   Food is broken down and absorbed into the body, so there is a high likelihood that the effects of consuming GM foods will be very similar.
  • Another is that we do not consume the same diet in content so therefore they are not comparable.
    • My response: we do not consume the same ratios of foods as other animals, but we do regularly consume the same foods.  In this instance we are referring to GM foods.  In fact, I think many of us are completely unaware how much we do consume, given that GM soy and corn is in a large portion of packaged and prepared foods.
  • My overarching concern is fact that these reactions are occurring at all!  It truly shakes me to the core that we as people would even be open to consuming these foods given the possibility that this could be causing the same symptoms in us as it does in the animals in these research studies.  We need to back the truck up and re-evaluate.

You will find more on the website, and you will see more from me on the research that should be turning the world inside out.  I encourage you to do your own digging and educate yourself so that you know the truth.

  1. Wow! This really makes you think twice about what we are putting inside our bodies. It makes me nervous to eat a lot of things. Some days trying to avoid all GMO (which I do prefer to do) leaves me with not many choices that always appeal to me. I need to change my and my childrens food desires for the healthier…not to mention safer! Thank you for this information.

    1. It is difficult to stay encouraged isn’t it? Or not develop some sort of food paranoia. I have never been one that likes eating the same things over and over again but I know that I don’t want to be sick either so I try to stay grateful! Don’t be too hard on yourself either, it’s hard being a mom and it sounds like you do your very best 🙂
