Genetically modified corn is safe according to a large meta-review

genetically modified corn

As I have written, the scientific consensus says that genetically modified crops, like corn, are safe for humans, animals, and the environment. The real science, published in real scientific journals and not anecdotes, beliefs, misinformation, and lies, tells us that genetically modified agricultural products are safe.

A large meta-review of research into genetically modified (GM) corn has supported several findings that there are no safety signals — you can consume GM corn all day long and you will suffer no ill consequences.

Genetically modified crops are one of those modern technologies that many people avoid, mainly for irrational and unscientific reasons. Of course, many people push fear, uncertainty, and doubt (FUD) about GMOs using little or no scientific evidence to support their claims.

But I’m here to provide real, published, peer-reviewed scientific evidence that contradicts that fear about GMOs – well, at least about GMO corn.

Humans have genetically modified crops for 10,000 years — yes, it’s true

genetically modified crops

The anti-GMO movement says that nature does it better for food, ignoring the fact that humans have been genetically modified crops for over 10,000 years. In other words, some people believe that our ancestors’ foods are somehow better than modern foods. But our ancestors were selectively breeding plants and animals since the dawn of agriculture. They just didn’t know about DNA, but they knew what they were doing.

Strangely, people seem to endow “nature” with a special status that is ridiculous. As if nature was for the benefit of humans, rather than being just plain random events.

Evolution proceeds along a random process where environmental changes select for certain mutations over time (and yes, I’m oversimplifying the process), which is called natural selection. Moreover, there are random mutations that just occur that provide no benefit to the organism, although they might in the future because of some environmental change.

Nature has no goal. It has no guidance. It has no underlying value of good or evil. Unless you believe that some higher being controls it, and at that point, you’re a creationist, claiming that “nature” is better than the alternative is ridiculous.

So, we’re going to talk about how humans genetically modified crops have moved from the early days of waiting for a random, beneficial mutation to the modern world of bioengineering.

GMO science — consensus says they are safe for humans, animals, environment

GMO science

I keep reading statements that there is no GMO science that says that they are safe for humans and the environment. And that they harm the productivity of farms. But GMO science says something completely different.

There is a scientific consensus that GMOs are safe and increase the productivity of farming. They help feed and protect humans all across the world. But still many reject this consensus of GMO science and block important foods that could save hundreds of thousands of lives. Just read about “golden rice,” a wonderful development of GMO science but is being blocked by many anti-GMO groups.

I want to review the scientific consensus behind GMO crops for those who think that there is no science supporting its safety and productivity.

DNA in vaccines and GMOs – they’re not going to turn you into Sasquatch

DNA in vaccines

One of the more pernicious tropes in the world of pseudoscience is that DNA in vaccines GMOs are going to magically incorporate into your cells changing you from a human into a sasquatch with ears of corn growing out of your head. Now that would be fun to see, but unless there’s a mad scientist out there trying to grow ears of corn out of a hirsute humane that looks like Sasquatch, it will probably never happen.

And most certainly consuming DNA in vaccines or eating GMOs with a new gene are not going to cause anything at all to any human I know.

But of course, science rarely gets in the way of good pseudoscience for anti-vaxxers and anti-GMO zealots. That’s why this old feathered skeptic in the dinosaur clade is here, to make sure the science is clear and to mock the pseudoscience.

GMO DNA transfers to humans – debunking a pernicious myth

GMO DNA

I keep reading of an annoying claim that GMO DNA transfers to humans easily, so that’s why we should be scared of it. Some of this belief is based on a poorly designed study that may, or really may not, indicate that plant GMO genes transfer to humans. These “researchers” claim that DNA may survive intact in the digestive tract and show up in the bloodstream.

Someone flunked basic human physiology and cell biology when they made this claim since it’s nearly biologically implausible to consider this to be real. Many of us have actually passed these courses so we are very skeptical.

In case you’ve ignored this area of false controversy, genetically modified crops are foods derived from genetically modified organisms (GMOs). Of course, all types of agricultural breeding induces genetic modification, but in general, GMO usually implies actual manipulation of the genes.

Based on some of the worst science available, the anti-GMO activists have condemned GMO foods as being dangerous. Unfortunately for the anti-science side, there is actually no science supporting these anti-GMO claims, and the vast scientific consensus says that GMO foods are safe to humans, animals, and the environment.

Let’s take a look at this paper that claims that GMO DNA gets into the human bloodstream.

GMO facts and myths – your one stop for scientific evidence

Genetically modified organisms (GMOs or GMs) are one of the most well-studied areas of biological and agricultural research. However, one of the tactics of the GMO refusers is that “there’s no proof that GMOs are safe.” It’s time to look at the GMO science facts – examining myth from science.

Typically, in a debate, the side making the assertion (those that say GMOs are unsafe) are responsible for the evidence that supports their contention. But, the anti-GMO gang relies upon the argument from ignorance, trying to force the argument to “if you can’t prove that they’re safe, they must be unsafe.”

The anti-GMO forces also like to invoke the precautionary principle, which attempts to shift the burden of proof to those who are advocating GMOs (or any new technology) until the advocates “prove” that there are absolutely no negative consequences of using GMOs.

The principle is often cited by anti-science and/or environmental activists when there is a perceived lack of evidence showing that this technology is absolutely safe.

I’ve written numerous articles about GMOs, focusing on scientific evidence supported by high-quality research. And more than a few articles debunked myths and bad research from the anti-GMO crowd. To assist those who are doing research on the topic, this article was created to be a one-stop shop for GMO science facts – and fiction.

GMO corn – safe and more productive according to new meta-review

GMO corn

As I wrote recently, the science is settled on “controversial” topics like vaccines and anthropogenic climate change. The science is also settled on genetically modified organisms (GMO) – real science, not anecdotes, beliefs, misinformation, and lies, tells us that genetically modified agricultural products are safe for the environment, for animals, and for humans. Now, we have a new, powerful study that shows us that GMO corn is not only safe but also increases production of corn.

GMOs are one of those modern technologies that many people avoid, mainly for irrational and unscientific reasons. Of course, many people push fear, uncertainty, and doubt (FUD) about GMOs using little or no scientific evidence to support their claims.

But I’m here to provide real, published, peer-reviewed scientific evidence that contradicts that fear about GMOs – well, at least about GMO corn. Continue reading “GMO corn – safe and more productive according to new meta-review”

Ten thousand years of GMO foods – making inedible edible

Ten thousand years of GMO foods

One of the tropes of the anti-GMO movement is that nature does it better for food, a logical fallacy. In other words, they believe that our ancestors’ foods are somehow better than our GMO foods. Of course, this belies the fact that there are over ten thousand years of GMO foods – it’s really not something that showed up during the last century or so.

People seem to endow “nature” with a special status that is ridiculous. Evolution proceeds along a random process where environmental changes select for certain mutations over time (and yes, I’m oversimplifying the process), which is called natural selection. Moreover, there are random mutations that just occur that provide no benefit to the organism, although they might in the future because of some environmental change.

Nature has no goal. It has no guidance. It has no underlying value of good or evil. Unless you believe that some higher being controls it, and at that point, you’re a creationist, claiming that “nature” is better than the alternative is basically ridiculous.

So, we’re going to talk about how genetic modification has moved from the early days of waiting for a random, beneficial mutation to the modern world of genetic modification.

Monsanto glyphosate causes cancer – so do apples

Monsanto glyphosate

Monsanto glyphosate (Roundup)  is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses that are known to compete with commercial crops grown around the world. It has several advantages over many herbicides in that it breaks down in the soil into non-toxic organic molecules, reducing or eliminating contamination of groundwater and lower soils.

Monsanto has developed genetically modified (GMO) grains that are resistant to glyphosate, so that agriculture can apply the herbicide to kill the competitive weeds while not harming the crop. This allows farmers to suppress the weeds while allowing better production out of the grain crop.

Whatever the benefits of Monsanto glyphosate, GMOs and the herbicide are tied together in many minds. And there has been an ongoing effort by many people to claim that glyphosate causes cancer. But let’s look at the science, because maybe we’ll get some information.

GMO science – overwhelming consensus that it is safe

GMO science

Real science is hard. It takes lots of high quality evidence to support it. That evidence needs to be published in real journal. It needs to be repeated. And it has to be open to criticism and analysis. GMO science, the study of genetically modified organisms used for crops and food, shows us that GMOs are safe.

The hard work and intellectual challenges to form a scientific consensus about the safety of GMO crops and foods isn’t something that appeared out of the ether. These individuals didn’t suddenly wake up one day and proclaim from the ivory tower that GMO science says that GMOs are safe. Not even close.

Science has provided substantial evidence supporting the assertion that GMO’s are safe. GMO refusers have provided precious little evidence, save for Cherry PickingSpecial Pleading, and a few Strawman Arguments. Oh, and the occasional Poisoning the Well with the Monsanto shill accusations. Sometimes the GMO deniers will resort to the Naturalistic Fallacy that things that grow “naturally” ought to be the way foods should be – this ignores the fact that we’ve been genetically manipulating our food for ten thousand years. We’re just better at it today, but the DNA is still the DNA.

Like I said in another article, “The typical pseudoscientist will use logical fallacies to state very definitively that “it’s proven.” It’s the same whether it’s creationism (the belief that some magical being created the world some small number of years ago), alternative medicine (homeopathy, which is nothing but water, has magical properties to cure everything from cancer to male pattern baldness), or vaccine denialists. The worst problem is that in the world of the internet, if you Google these beliefs, the number of websites and hits that seem to state that they are THE TRUTH™ overwhelm those that are more skeptical or critical.”

So, using an open, but critical mind, the evidence is overwhelming – the GMO science says it’s safe for human consumption.
