Genetically modified food proven to cause organ and endocrine damage

Finally, actual physical proof that genetically modified food causes organ damage. In an elegant recent French data analysis, three GM corn strains were shown to cause damage to rats fed the corn for 90 days. I won't go into too many specifics, the article in the International Journal of Biological Sciences can be read in full here. But for those of you not willing to wade through the medical terms and experimental facts, figures and graphs I will sum up as best I can.

• Rats were fed three genetically modified corn strains (interestingly two of them were developed by Monsanto, my most hated large agro-conglomerate).
• All three of these GM crops have genes in them that either tolerate mass exposure to the herbicide Roundup (therefore having Roundup residue in them) or manufacture their own pesticides. To quote the article "Therefore, all these three GM maize contain novel pesticide residues that will be present in food and feed."
• Detrimental health effects were different for male and females, which is not surprising as pesticides and herbicides can interfere with endocrine functions.
• "Effects were mostly concentrated in kidney and liver function, the two major diet detoxification organs, but in detail differed with each GM type. In addition, some effects on heart, adrenal, spleen and blood cells were also frequently noted."

The authors stress that this study was only conducted over a 90 day period and long term studies are necessary. If you think about it, we've all been eating GM food since they were introduced in the early 1990s. What really scares me is children who are exposed to GM food from infancy. Unless you buy organic the cereals, french fries, corn chips and cookies your kids are eating are mostly likely made from GM grains.

Even baby formula made from cow's milk is manufactured from cow's most likely fed GM corn. One more reason to buy organic! I shudder to think what this is doing to their little endocrine systems. I am lucky that we can afford organic formula and now milk. But, a lot of parents either can't afford it or don't think it's necessary.

The most interesting fact about this study is it wasn't conducted by the French authors. These data were actually collected by Monsanto or on behalf of Monsanto. The authors actually had to go to court to obtain the results as stated in this paragraph below:

"The raw biochemical data, necessary to allow a statistical re-evaluation, should be made publically available according to European Union Directive CE/2001/18 but unfortunately this is not always the case in practice. On this occasion, the data we required for this analysis were obtained either through court actions (lost by Monsanto) to obtain the MON 863 feeding study material (June 2005), or by courtesy of governments or Greenpeace lawyers. We thank the Swedish Board of Agriculture, May 30, 2006 for making public the NK 603 data upon request from Greenpeace Denmark and lawyers from Greenpeace Germany, November 8, 2006 for MON 810 material. This allowed us to conduct for the first time a precise and direct side-by-side comparison of these data from the three feeding trials with these GMOs."
