Study Links GM Corn Consumption to Organ Damage

A recent E.U. study found that rats who’s diets included different strains of Monsanto’s genetically modified (GM) corn experienced kidney, liver, and other organ damage.

[social_buttons]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? Over at, you can 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.
