GMOs and Organ Damage

A recent E.U. study found that rats whose diets included different strains of Monsanto’s genetically modified (GM) corn experienced kidney, liver, and other organ damage. The study looked at three strains of Monsanto’s GM corn: one that was “Roundup Ready” and two that were engineered to produce Bt toxin which acts as an insecticide.

Because Monsanto’s seeds are patented, researchers had to use data that came from the GM giant itself, rather than conducting their own research. Researchers had to actually take Monsanto to court to get their hands on the data for analysis!

They found that after just 90 days, the rats in the study began to show symptoms. The male rats had stronger reactions across the board than female ones. In addition to affecting the heart and liver, the researchers found “some effects on heart, adrenal, spleen and blood cells.”

In concluding their writeup of the study, the researchers added:

These substances have never before been an integral part of the human or animal diet and therefore their health consequences for those who consume them, especially over long time periods are currently unknown.
Our analysis highlights that the kidneys and liver as particularly important on which to focus such research as there was a clear negative impact on the function of these organs in rats consuming GM maize varieties for just 90 days.

Get Heard
Want to let the FDA know how you feel about genetically modified corn? Sign a letter to FDA Commissioner Margaret Hamburg asking the agency to take action.

In the meantime, you might want to add corn to your list of foods to always buy organic. Avoiding conventional corn is a little bit tricky, since corn-derived ingredients like high fructose corn syrup are so ubiquitous.

Monsanto is FDA. FDA is Monsanto. I refuse to buy corn Ior corn products) unless certified organic. In California that means CCOF (California Certified Organic Farms). I'm currently living in China, where I don't buy corn.
If GMOs eventually wipe out all natural corn, Monsanto will be delighted. Science needs to be protected against corporate greed. Right now we have too few Einsteins and too many Frankensteins.

There should be stronger watch on GMO. In Australia Greenpeace recently found that GM soy was used in some baby and child food, and was not mentioned on the label, which is against the law.

Former Monsanto officials now work in top posts at various US government agencies allowing Monsanto free reign to continue poisoning our food supply. GMOs are an ecological disaster and Monsanto needs to be prosecuted for its crimes against nature, the food supply and all life. See:

Former Monsanto officials have infiltrated top posts in various US government agencies so Monsanto is given free reign to continue to poison the food supply and the earth with their GMOs; other toxic offerings by Monsanto are Agent Orange and PCBs. This company should be brought to justice and prosecuted for its crimes against the earth and all life. See my petition:
