Something in the GM Soy Diet Was ‘Wrecking the Ovary and Endometrium’ of the Rats

September 29th, 2010

The opening words of the piece below are, “If you’re still eating genetically modified (GM) soybeans…”

People might read the article and think, “I don’t eat genetically modified soybeans, so this doesn’t apply to me.”

If you’re eating any industrial/feedlot/factory meat, you’re eating genetically modified soybeans. It’s in the feed that the animals are given. Chicken feed has the highest amount of soy added of all the livestock feeds. (FYI: Raw soybeans are poisonous for chickens. They have to be cooked to make the soy protein usable by chickens.)

Additives made from genetically modified soybeans are present in most conventional processed foods.

In other words, unless you’re making a conscious effort to avoid GM soybeans and the foods that contain them, including industrial/feedlot/factory meats, you’re eating a GM soy diet.

If you’re still eating genetically modified (GM) soybeans and you plan on having kids, a Brazilian study may make you think again about what you put in your mouth. Female rats fed GM soy for 15 months showed significant changes in their uterus and reproductive cycle, compared to rats fed organic soy or those raised without soy. Published in The Anatomical Record in 2009, this finding adds to the mounting body of evidence suggesting that GM foods contribute to reproductive disorders (see summary at end).

Unlike women whose menstrual cycle starts automatically at puberty, female rats need to be “inspired.” Their (estrous) cycle conveniently kicks in only after being introduced to male rats. Since no males were present in this study, the females fed organic soy or no soy were appropriately untriggered (diestrus). For some odd reason, however, those fed GM soy appeared to have their ovulation cycle in full gear.

Although the researchers did not perform a check on the estrous cycle directly, their microscopic analysis of ovaries and uterus tissue showed that the hormone-induced changes (i.e. early ovulation and formation of corpus luteum) were well underway. In addition, the lining of the uterus (endometriim) had more cells than normal and the glands were dilated. In simpler terms, according to senior UK pathologist Stanley Ewen, something in the GM soy diet was “wrecking the ovary and endometrium” of the rats.

Genetically modified soybeans are called Roundup Ready. They are inserted with a bacterial gene, which allows the plants to survive a normally deadly dose of Roundup herbicide. Although the spray doesn’t kill the plant, its active ingredient called glyphosate does accumulate in the beans themselves, which are consumed by rats, livestock, and humans. There is so much glyphosate in GM soybeans, when they were introduced Europe had to increase their allowable residue levels by 200 fold.

Although there is only a handful of studies on the safety of GM soybeans, there is considerable evidence that glyphosate—especially in conjunction with the other ingredients in Roundup—wreaks havoc with the endocrine and reproductive systems. “I think the concentration of glyphosate in the soybeans is the likely cause of the problem,” says Ewen.

Glyphosate throws off the delicate hormonal balance that governs the whole reproductive cycle. “It’s an endocrine buster,” says Ewen, “that interferes with aromatase, which produces estrogen.” Aromatase is required by luteal cells to produce hormones for the normal menstrual cycle, but it’s those luteal cells that have shown considerable alterations in the rats fed GM soybeans.

    So again. Its not the GM soy thats harmful, its the surrounding corporate ideology.

    GM soy could save the world with faster adaption to drought, salty soils and bad farmers. But no, they must spray chemicals everywhere and thus killing a urgently needed option to mitigate widespread suffering in our world.

    GM soy could save the world…

    Is that sarcasm?

    I’m not sure what you mean “Oelsen” but reading this article, I beat mystelf up again for the thousandth time for not knowing what the soy in the liquid food my mother was ingesting did to her.
    @oelsen – it doesn’t matter if soy is genetically modified – its a killer, a hormone distruptor, and is regulated in Europe (if you’ve been reading and listening to Kevin’s post’s on the topic).
    Soy is a FILLER CROP. A WAY FOR FOOD COMPANIES TO MAKE MONEY AND FLUCK THE IMPACT ON THE HUMANS WHO EAT IT. PERIOD.
    Sorry, I have strong feelings on the subject of soy. Oh my, I must be a terrorust because I resent that a hospital gave my mother food in a can that was poison and I didn’t know it was poison until it was too late. Like 10 years too late. Something I’m going to live with for a long time.
    Ah well, that’s just me. Going through another one of my resentful rants about soy products as I digress into another post traumatic syndrome episode.

    Agreed.

    Apparently it’s the ‘modification’ itself that’s the problem. When you change a gene so that you can cross it with life forms that are unnatural to it, you open a Pandora’s Box. It can now cross with ANY genes.

    So for instance, a fish could never cross genes with a vegetable in nature…but GM corporations can do that, and have.

    So evidently now the genes within that vegetable, when you eat it, can cross with, say, your intestinal lining. Causing changes which probably first result in acquired allergies of one form or another. Which we’re seeing. But then what?

    Anyone remember what that Japanese medicine was that debilitated or killed all those people? It was the GM component that was to blame. American companies are smarter…them make sure people don’t fall ill immediately or in any traceable manner.
