(NaturalNews) A report published in thehas verified once again that Monsanto's genetically modified (GM) crops are causing severe health problems. A legal challenge issued against Monsanto forced the multi-national agriculture giant to release raw data revealing that animals fed its patented GM corn suffered liver and kidney damage within just three months.Adding to the mounting evidence that GM crops are dangerous all around, this information provides a damning indictment against Monsanto which continually insists that its GM products are safe. Not only are GM crops proving disastrous for the environment, but study after study, including those conducted by Monsanto itself, is showing that GM foods are detrimental to health.Monsanto's data indicated that the company had conducted tests on three varieties of its GM corn, two of which contain the dangerous Bt protein, and one designed specifically to resist Monsanto's Roundup herbicide. All three are widely grown in the United States while only one is currently grown in Europe.Dr. Gilles-Eric Seralini, a French researcher from the University of Caen, was tasked with examining the data and providing a review. While stopping short of declaring GM crops to be toxic, he did emphasize that chronic negative effects were apparent and that there were "statistically significant" indications of kidney and liver damage.The specific effects observed in test rats included a buildup of hormones in the blood, indicating that their liver and kidneys were not functioning properly. One variety of the corn led to elevated blood sugar levels and increased triglyceride levels in female rats given it.Dr. Seralini concluded that, because GM crops are foreign substances that have never been a part of a normal diet, there is no telling what the long-term effects of consumption will be on people. In animals, significant disruption of normal bodily function has been observed even in the short term.Genetically manipulated food crops are not fit for human consumption and should not be classified as food. No legitimate study has ever proven them to be safe or nutritious. The burden of proof is on the producers of such crops to verify their safety and, to date, all data has revealed that they are unsafe. Claims that GM foods will end world hunger are baseless, propagated only by those that have a financial interest in converting the world's food supply to their own patented varieties in order to control it.Sources for this story include:
