Gilles-Eric Séralini and colleagues surveyed the state of research and found GMOs Linked to Organ Disruption in 19 Studies, as Jeffrey Smith reports for the Institute for Responsible Technology.
...consuming genetically modified (GM) corn or soybeans leads to significant organ disruptions in rats and mice, particularly in livers and kidneys. ...9% of the measured parameters, including blood and urine biochemistry, organ weights, and microscopic analyses (histopathology), were significantly disrupted in the GM-fed animals. The kidneys of males fared the worst, with 43.5% of all the changes. The liver of females followed, with 30.8%. The report, published in Environmental Sciences Europe on March 1, 2011, confirms that "several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects." The authors point out that livers and kidneys "are the major reactive organs" in cases of chronic food toxicity.And these were the corn and soybeans that people eat.
Here's the study.
Why didn't we know about this long ago?
the authors demonstrate how a multitude of GMO-related health problems could easily pass undetected through the superficial and largely incompetent safety assessments that are used around the world.And the effect are not limited to the first generation that eats this stuff:
One of the most glaring faults in the current regulatory regime is the short duration of animals feeding studies. The industry limits trials to 90 days at most, with some less than a month. Only two studies reviewed in this new publication were over 90 days—both were non-industry research.
Short studies could easily miss many serious effects of GMOs. It is well established that some pesticides and drugs, for example, can create effects that are passed on through generations, only showing up decades later. IN the case of the drug DES (diethylstilbestrol), "induced female genital cancers among other problems in the second generation." The authors urge regulators to require long-term multi-generational studies, to "provide evidence of carcinogenic, developmental, hormonal, neural, and reproductive potential dysfunctions, as it does for pesticides or drugs."That's right, we're quite likely affecting our own children and grandchildren by what we eat.
Nearly all GM crops are described as "pesticide plants." They either tolerate doses of weed killer, such as Roundup, or produce an insecticide called Bt-toxin. In both cases, the added toxin—weedkiller or bug killer—is found inside the corn or soybeans we consume.That's right, not only does the pesticide linger in the food, the food itself produces a toxin.
And lack of labelling not only makes it hard for people to pick what they want to eat, it has another consequence:
But even if authorities wanted to conduct epidemiological studies on GMOs, the authors acknowledge that they “are not feasible in America, since there is no organized traceability of GMOs anywhere on the continent.”So maybe we should get labelling laws passed. And meanwhile local organic food is a booming market.
