De omnibus dubitandum
13 Aug 2013
Genetically modified organisms – GMO – are a hot topic at the moment, with loads of people weighing in on the debate. Especially the anti-GMO stance receives a lot of attention, fuelling scare stories about the hazards of GMO crops and food.
However, there seems to be precious little facts in these scare stories. Fortunately there have also been a few recent articles that provide a more balanced, fact-based perspective on GMO foods:
This thoroughly researched article on Slate debunks a GMO scare story published in Elle magazine – not quite a staple of fact-based reporting – and delves deeper in to the scientific evidence about GMO foods.
Turns out there’s no evidence whatsoever suggesting that GMO food is any more dangerous than regular food:
“Since GMOs were introduced into the food supply almost 20 years ago, there has not been one documented case of any health problem in humans—not even so much as a sniffle—linked to GMOs. The American Medical Association, whose physician members would have long ago picked up on a GMO-allergy connection, definitively rejects such speculation. “Bioengineered foods have been consumed for close to 20 years, and during that time, no overt consequences on human health have been reported and/or substantiated in the peer-reviewed literature,” it has stated. That scientific consensus has been endorsed by every major science oversight body in the world.”
But, say the GMO skeptics, what about the correlation between the growing consumption of GMO food in America and the rise in autoimmune disorders?
“The rise in such problems, including allergies, started long before GMOs were introduced. Incidences of these same conditions across U.K., Europe and in other countries where there is no consumption of GM foods match U.S. trends. To put this claim in perspective, the upward slope also tracks with the cumulative wins of the New England Patriots under Bill Belichick, the GDP of China, and indeed the increased consumption of organic foods over a similar period of time. In other words, the alarming connection that Shetterly alludes to in her piece is completely random.”
An article on Grist explores the issues of allergenic proteins originating from GMO foods. Turns out that in this respect GMO foods are actually safer than regular foods and are being tested much more thoroughly for new allergens:
“First, there just aren’t many new proteins in GE food (all allergens are proteins) — you are adding just a couple. It’s much riskier to introduce a new food from another country, each of which contains hundreds of new proteins, Taylor wrote, and yet we subject new foods to less safety testing. (When the first kiwis were shipped into the United States in 1962, they weren’t tested because they were an established food, but, as it turned out, they did cause allergic reactions in some people.)
Furthermore, Taylor said, the new genes in transgenic plants generally express very low amounts of protein (when a gene causes an organism to make a protein it’s called expression). Allergens generally account for more than 1 percent of the proteins in a food, while the proteins expressed by transgenic DNA are much more sparse.”
The New York Times published a balanced piece about the use of genetic modification to help oranges resist a specific type of bacteria:
“Oranges are not the only crop that might benefit from genetically engineered resistance to diseases for which standard treatments have proven elusive. And advocates of the technology say it could also help provide food for a fast-growing population on a warming planet by endowing crops with more nutrients, or the ability to thrive in drought, or to resist pests. Leading scientific organizations have concluded that shuttling DNA between species carries no intrinsic risk to human health or the environment, and that such alterations can be reliably tested.”
Many anti-GMO activists point to the evils of Monsanto and how scientific studies are funded by biotech companies and thus cannot be trusted. But there’s abundant independent research in to GMO foods (over a third of peer-reviewed studies on GMO are independently funded), and a great many independent health organisations have undertaken their own studies in to the health risks associated with GMO crops.
The results are unanimous and clear: GMO foods are perfectly safe, and probably necessary to maintain sustainable agriculture that sufficiently feeds our growing population.
While I consider myself a left-wing thinker, on this particular issue I vehemently disagree with the anti-GMO stance prevalent in the political left.
For me it’s a bit like climate change, vaccination, and evolution: there is an unassailable scientific consensus, with only a tiny minority of dissenting voices that lack any form of empirical evidence. Unfortunately in this case public opinion is eager to embrace the – very vocal – fringe lunatics.

Day after day we’re being bombarded with messages about how bad the food is that we eat and how toxic the drinks are that we consume.
You can only conclude from all these articles, TV ads, news reports, and Facebook virals, that the human species on the whole is dreadfully unhealthy.
Apparently we need to embrace the forgotten ways of our ancestors, eating and drinking only the pure output from mother nature, skipping all the industrial processing and chemical wizardry that goes on in modern food production.
Because apparently living that pure ‘organic’ and ‘holistic’ lifestyle will make us happier and healthier, and result in longer and more fulfilling lives. Just like our pre-industrial, medieval ancestors.
Those same medieval ancestors that had an average lifespan of around 40 years and tended to lead short, miserable, malnutritioned lives. Right.
The next time you read an article about how bad Coca-Cola is for you, or you see a TV ad for ‘organically grown food’ (is there any other way for food to grow?), or you listen to some hemp-wearing hippy moan on about the dangers of modern medicine, realise this:
Humans today live longer and healthier lives than ever before in the history of the human species.
Now if you’ll excuse me, I have a Mars bar that I need to wash down with a nice cool can of Coke.
