GMO's - The Dangerous Truth, Monsanto has lots to hide

although there may not at the moment be definitive proof that GMOs harm humans, there is a truckload of evidence that people might want to be aware of before deciding whether to eat, or feed their families, GM foods.
For starters, according to a statement signed by nearly 300 scientists and legal experts in late 2013, no epidemiological studies in human populations have been carried out to establish whether there are any health effects associated with GM food consumption. The statement, posted here, affirmed that there was no scientific consensus on GM food safety.
Furthermore, short of definitive proof of harm, there is considerable evidence of possible harm that a person might reasonably consider in deciding whether to eat GMO foods. A 330-page report, “GMO Myths and Truths” (herein, “the Report”), reviews a great many studies raising questions about GMO safety. The Report is available for  download here.
The Report summarizes feeding studies on laboratory and farm animals in which a GM diet was fed to one group of animals and a non-GM diet was fed to a control group. The studies found “signs of toxicity or actual toxic effects in the GM-fed animals, meaning that the GM foods tested were more toxic or allergenic than the non-GM foods.” (Report, page 129)
Some examples: Mice fed GM Bt maize showed “a marked disturbance in immune system cells and in biochemical activity.” Mice fed for five consecutive generations with GM herbicide-tolerant triticale (a wheat/rye hybrid) developed enlarged lymph nodes and immune disturbances, in comparison with controls. Mice fed GM soy showed “disturbed liver, pancreas and testes function.” A review of 19 studies on mammals fed commercialized GM soy and maize found “consistent signs of toxicity in the liver and kidneys.” (Report, pages 131-133)
To GM proponents’ claim that such effects are not “biologically relevant” or “adverse,” the authors of the Report, two genetic engineers and a researcher, reply that these terms have never been properly defined in the context of animal feeding trials with GMOs, and are “scientifically meaningless.” (Page 128)
