Another Reason to Avoid GMOs (As If You Needed One)
Dear Living Well Daily Reader,
I hate to preach to the choir. You already know to avoid GMOs.
You know that rat studies indicate they may cause tumors and reproductive defects.
But as I was talking with Brad Lemley, editor of Natural Health Solutions, a few weeks ago, an interesting question came up:
Are the ill effects from GMOs due to their genetic modification? Or do they create problems because they are sprayed with much greater amounts of pesticides and herbicides than non-GMO crops?
Or perhaps it’s due to a combination of both factors?
I tend to think the genetic manipulation does indeed play a major role.
GMO Bt corn, for example, is spliced with a gene from a bacteria called Bacillus thuringiensis (hence the Bt in Bt corn).
That particular gene produces an endotoxin that kills the European corn borer, a major pest to corn. And it does this by the following:
When a corn borer takes a bite of the corn with the Bt toxin, the toxin binds to the gut wall of the insect and causes the gut lining to break down. Then, the bacteria in the gut of the corn borer enter the blood and body of the worm and cause it to perish. 1
Though some scientists say that the toxic effects from Bt are “selective” and “safe for humans,” I’m not buying it.
The incidence of both intestinal permeability and inflammatory bowel disease in humans is on the rise. And the latter actually correlates nicely with the introduction and use of Bt corn:
And a study on pigs fed GM corn found that they had increased levels of stomach inflammation compared with pigs fed non-GM corn. 2
So back to the question of genetic modification versus pesticides — this particular genetic modification actually allows less pesticide use on corn, hinting that it’s not just the pesticides that are contributing to issues with GMOs.
But. (There’s always a but…)
The pesticides and herbicides are still an issue. Even if you don’t eat GM foods, you need to beware of pesticides and herbicides on non-GM foods.
And here another reason why: The EPA just approved the use of a new herbicide called Enlist Duo.
This chemical cocktail is a combination of glyphosate (Roundup) and 2,4-D (a component of Agent Orange).
As more and more weeds become resistant to Roundup, new herbicides are being created to combat the issue. And Enlist Duo is just in time to be used with GM seeds that are resistant to glyphosate and 2,4-D.
But as Dr. Philip J. Landrigan pointed out in an editorial published just last week in the New England Journal of Medicine, the EPA a huge mistake in approving Enlist Duo. 3
For one, the International Agency for Research on Cancer (IARC) has classified glyphosate as a “probable human carcinogen.” Yes, not just a possible carcinogen but a probable one.
The IARC also classified 2,4-D as a “possible human carcinogen.”
In addition, Dr. Landrigan believes that the science supporting the approval of Enlist Duo is outdated. It was commissioned in the ’80s and ’90s (by the herbicide manufacturer, no less), and the studies were not designed to detect the herbicides’ low-dose effects on genes and endocrine function.
The studies also shed no light onto potential health effects in infants and children, and do not take ecological considerations into account.
Lastly, the studies considered only pure glyphosate, not what is actually being used. Roundup contains surfactants and adjuvants that make it even more toxic.
And according to the EPA, this new approval will increase the use 2,4-D up to seven-fold, further saturating crops with this potential cancer-causing chemical.
The good news?
By choosing organic foods, you can avoid the whole mess. Organic foods must be non-GMO, and they cannot be grown with the use of pesticides or herbicides (among other rules).
And a new (albeit small) study published in the journal Environmental Research showed that by switching to mainly organic foods for as little as seven days, people were able to reduce organophosphate pesticide levels in their urine by almost 90 percent. 4
If you give your body the chance, it will try as hard as it can to detoxify itself from these chemicals.
So like I said earlier, I know I’m preaching to the choir here. But if you have a family member or friend that hasn’t quite gotten on board with avoiding GMOs and pesticide-laden foods, now you have a few more facts in your arsenal to share with them.
And if you’re like me and sometimes get lazy and don’t buy organic just to save a few bucks, a little reminder on the dangers of chemical-laden foods may be just what you (read: I) needed.
