What does science say about GMO’s–they’re safe

The science deniers of the world, whether they deny evolution, global warming, vaccines, or GMO safety, spend their time inventing pseudoscience to support their beliefs and claims. As I have written previously, “Pseudoscience is easy. It doesn’t take work. It’s the lazy man’s (or woman’s) “science.” But it has no value, and because it lacks high quality evidence in support of it, it should be dismissed, and it should not be a part of the conversation.”

Alternatively, real science is really hard. And it takes time. And it’s based on high quality evidence. And it is repeated. And it is almost always published in high quality journals. As I’ve said a thousand times, real science takes hard work and is intellectually challenging. You just don’t wake up one day and say “I’m a scientist.” No, it requires college, graduate school, teaching, working in world class laboratories, publishing, defending your ideas to your peers, and one day, if you don’t stop, you will be an authority in your little field of science.

The anti-GMO crowd is mostly lazy. They have this luddite belief that all technology is bad, but have absolutely no evidence to support it. Sure, they pick out one or two poorly done articles and then shout for all the world to hear “GMO’s are dangerous to…bees, humans, babies, whales, trees” over and over and over again.  Yet what do the GMO refusers really bring to the table? 

Without really trying (though it took several days to read through the articles), I found 114 peer-reviewed articles, mostly published in moderate to high impact factor journals that support the safety of GMO crops over a wide range of hypotheses: from transgenic particles in bovine milk to how non targeted insects survive (or don’t). I found several meta reviews, which, as I’ve said before, are the highest quality sources of evidence. None of this research was sponsored by corporations, and frankly, I didn’t have enough time to read all those articles in addition to the ones included here. I even went to the effort to find the 2012 Impact Factors for each of the journals, so you know the quality of the journal. Note that impact factors, though I rely on them, are an imperfect measurement, much like a batting average for a baseball player doesn’t fully explain the skills that he may or may not have.

There were hundreds of other articles I could have included. But these are the ones I judged to be the best. And if you add up all of the conclusions written, a consensus forms. And that is that GMO’s are generally safe. There will be no transgenic DNA in your glass of milk. The transgenic DNA isn’t going to be absorbed through your intestine and cause some autoimmune reaction.

And I just didn’t find the articles that supported my “beliefs” or “opinions.” I found the best articles period. I found the articles that supported the broad scientific consensus that GMO foods are safe.

The American Association for the Advancement of Science (AAAS) is a prestigious international non-profit organization that has as its stated goals to promote cooperation among scientists, to defend scientific freedom, to encourage scientific responsibility, and to support scientific education and science outreach for the betterment of all humanity. AAAS is the world’s largest and most prestigious general scientific society, and is the publisher of the well-known scientific journal Science

The AAAS emphatically states that evolution and human caused climate change are scientific facts, so the organization is not in the hands of scientific lunatics or deniers.

And the AAAS has clearly and unreservedly published the scientific consensus regarding genetically modified foods (pdf):

The science is quite clear: crop improvement by the modern molecular techniques of biotechnology is safe … The World Health Organization, the American Medical Association, the U.S. National Academy of Sciences, the British Royal Society, and every other respected organization that has examined the evidence has come to the same conclusion: consuming foods containing ingredients derived from GM crops is no riskier than consuming the same foods containing ingredients from crop plants modified by conventional plant improvement techniques.

But, if the GMO refusers want to provide real scientific evidence that GMO foods are dangerous, I’ll be glad to read it. I’ll be thrilled to write about it, because I happen to be openminded about ALL science. But right now the scientific consensus supports GMO safety.

But be forewarned, if it is junk science, I will call it junk science, like Gilles-Eric Séralini et al.’s paper about GMO corn causing cancer. Except it was poorly designed, utilized bad statistics, and really provided no evidence whatsoever for anything except that Séralini is an incompetent scientist. Because openminded doesn’t mean I accept all evidence as being equivalent–being openminded means a willingness to review and critique new data and determine if it’s of sufficient quality and quantity to move the consensus. Claiming that Monsanto or Big Agra are suppressing the evidence is simply a logical fallacy unworthy of discussion.

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 Big Agra shill accusations. 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.”

But the most important thing is that science isn’t a vote based on the number of papers published. But when the consensus is so heavily weighted to the safety of GMO’s, it’s hard to see anything but a landslide. Now, I know that the typical GMO refuser will cherry pick a couple of poorly designed studies and try to refute all of these. Or they’ll read one or two of the articles, and pick out a sentence that might say “GMO fields showed slightly less insect activity than unused land” (while ignoring all of the other sentences).

If you’re asserting that GMO’s are dangerous–provide evidence. And it better be published in a relatively high impact journal.

    I have read several of your articles about GMO’s and I can
    say that you have convinced me not to buy GMO’s and to avoid them
    altogether. Thank you for the information.

  • skyoss

    This blog will from now on be known as the “Confused Gecko” and I have changed my icon in your honor. You have crafted an article with a title implying that the long term ingestion of genetically engineered foods is safe for humans, and then you proceed to link out to studies on mildew, rats, pigs, and rodent genitalia. You have provided not one human study in your reference list, not one. You have erected multiple straw-men named: “the nutritional profile of genetically engineered wheat is similar to conventional wheat” or “the testicles of mice are no smaller when fed genetically engineered diet versus conventional diet” etc etc. As if the safety of genetically engineered foods for human consumption can be inferred via studying mice testicles. The actual question here is:

    **********”Are genetically engineered foods safe for long term human consumption”.**************

    So please my little gecko friend, no more straw-man arguments, find me some longitudinal double blinded studies on humans that demonstrate safety. I want data on weight gain, inflammation, rheumatological issues, auto immune dysfunction and birth defects to start. I recognize that it will take you some time, a long long long time but I will check back to see what you have come up with. Until then the only thing I care to hear from you is the rhythmic crunching of cricket carcasses in your gecko jowls..

    My friend – it is an issue of trust, not science. You are absolutely correct that most people have not reviewed the studies done on GMO safety to come to their conclusions, yet they still mistrust – ask yourself really and honestly why that is?

    Why are GMO companies against labeling for consumers? Isn’t lobbying against transparency in itself a red flag?

    Would you trust large human institutions whose main goal is to take more of your money with the least expense to itself? Institutions with a long history of incurring and hiding externalized human and environmental costs?

    You mention peer review and consensus, but is not “group think” a pernicious political reality? Does not the history of science reflect established, consensus paradigms being toppled?

    Is science really the best tool for solving complex multi factorial problems? Why in the age of science are people so obese, when in more ignorant times they were thin? Why in the age of science so many depressed? Why hasn’t science solved those problems?

    Do I need peer reviewed studies to deal with political issues? Is it really so irrational to mistrust GMOs in light of the political realities surrounding them?

    How can the author assert there is consensus? The US National Institute of Health reports that peer-reviewed animal feeding studies of GMOs found roughly an equal number of research groups raising concerns about genetically engineered foods and those suggesting GMOs were as safe and nutritious as conventional foods. The review also found that most studies finding GMOs foods the same as conventional foods were performed by biotechnology companies or their associates. The Royal Society of Canada and British Medical Association have noted that some GMOs could be of considerable harm, while there are no epidemiological studies investigating potential health effects of GMO food on human health. However, there is plentiful evidence that GM crops have caused increased resistance to herbicides, leading to increased use of herbicides overall and increased incidences of antibiotic resistant bacteria exposed to these GM crop herbicides. The herbicides have adverse health impacts on children, and due to their prolific use, saturate the air, ground and water as increasing volumes of herbicides are used to compensate for the rapid increase in herbicidal resistance.

      What the CONSENSUS says.

      “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.”
      – American Medical Association, 2012

      “No effects on human health have been shown as a result of the consumption of GM foods by the general population in the countries where they have been approved.”
      — World Health Organization, 2013

      “The science is quite clear: crop improvement by the modern molecular techniques of biotechnology is safe.”
      -American Association for the Advancement of Science, 2012

      The Royal Society of Medicine: ”Foods derived from GM crops have been consumed by hundreds of millions of people across the world for more than 15 years, with no reported ill effects (or legal cases related to human health), despite many of the consumers coming from that most litigious of countries, the USA.” (http://1.usa.gov/12huL7Z)

      The European Commission: ”The main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 independent research groups, is that biotechnology, and in particular GMOs, are no more risky than e.g. conventional plant breeding technologies.” (http://bit.ly/133BoZW)

      International Seed Federation: ”The development of GM crops has benefited farmers, consumers and the environment… Today, data shows that GM crops and foods are as safe as their conventional counterparts: millions of hectares worldwide have been cultivated with GM crops and billions of people have eaten GM foods without any documented harmful effect on human health or the environment.” (http://bit.ly/138rZLW)

      Consensus document on GMOs Safety (14 Italian scientific societies): ”GMOs on the market today, having successfully passed all the tests and procedures necessary to authorization, are to be considered, on the basis of current knowledge, safe to use for human and animal consumption.” (http://bit.ly/166WHYZ)

      Society of Toxicology: ”Scientific analysis indicates that the process of GM food production is unlikely to lead to hazards of a different nature than those already familiar to toxicologists. The level of safety of current GM foods to consumers appears to be equivalent to that of traditional foods.” (http://bit.ly/13bOaSt)

      “Transgenic Plants and World Agriculture” – Prepared by the Royal Society of London, the U.S. National Academy of Sciences, the Brazilian Academy of Sciences, the Chinese Academy of Sciences, the Indian National Science Academy, the Mexican Academy of Sciences, and the Third World Academy of Sciences:“Foods can be produced through the use of GM technology that are more nutritious, stable in storage, and in principle health promoting – bringing benefits to consumers in both industrialized and developing nations.” (http://bit.ly/17Cliq5)

      French Academy of Science: ”All criticisms against GMOs can be largely rejected on strictly scientific criteria.” (http://bit.ly/15Hm3wO)

      Union of German Academies of Sciences and Humanities: ”Food derived from GM plants approved in the EU and the US poses no risks greater than those from the corresponding conventional food. On the contrary, in some cases food from GM plants appears to be superior with respect to health.” (http://bit.ly/17ClMMF)

      International Council for Science: ”Currently available genetically modified crops – and foods derived from them – have been judged safe to eat, and the methods used to test them have been deemed appropriate.” (http://bit.ly/15Hn487)

    I have numerous issues with GMOs that don’t need scientific review:

    1: Monsanto controlling the food supply
    2: History that corporations will do anything to deceive and manipulate the public. Here are other things that were accepted as safe: Asbestos, uranium paint, early x-rays, lead in gasoline and paint, saccharine, ddt, cigarettes…
    3: Customers have every right to know where their food comes from.

    Judging by the number of articles I’ve been seeing in the past month that totally dismiss the Anti-GMO crowd and run smear campaigns against companies like Chipotle who are responding to CONSUMER DEMAND, it is clear that Monsanto is waging all out war.

    If you want to trust big corporations, go right ahead, I’ll stick to my organic food because it is my god-damned right!

    • Janice Rael

      Now that we know how you feel about Monsanto, please tell us how you feel about Dow, Bayer, DeKalb, Syngenta, Simplot, and other companies who make seed and herbicides safer and better.

      • ArthurFrayne

        Bayer was part of IG Farben – the chemical conglomerate that made Zyklon B – the gas used to exterminate the Jews that weren’t fit to be used as slave labor in IG Farben’s factory at Auschwitz. That said, none of those companies are going to the extreme lengths that Monsanto is to a) control our food supply, and b) finance legislation that would prevent states form requiring GMO labeling.

        • You win the Godwin Award for stupid strawman arguments.

          • ArthurFrayne

            And bringing up Godwin is just as much a straw man argument when you’d rather ignore history than look it square in the face. My initial post said “I have numerous issues with GMOs that don’t need scientific review:” That doesn’t mean the science isn’t there, it means that even if it wasn’t there, I still have valid issues with Monsanto. If you wish to trust corporations that is your right, but I’ll take the lessons of history and view them with a guarded eye.

      Spencer, I very well know the context in one of country of your list. I live in France and I follow this subject of GMO controversy for years. I can tell you that the ban of GMO in France has nothing to do with science. That is pure politics. How do you think a politician will act when a vast majority of electors “know” that GMO causes cancer ?

      Of course, like in any other country in the world, all the scientific institutions in France (including Academy of Science, Academy of Agriculture and all public research institutes including INRA and INSERM) supports the scientific consensus that genetically engineered crops as such are neither safer nor risquier than any other crops for both health and environment. Of course, French anti-GMO activists will answer that all scientific institutions are paid or influenced by industry (the good old Monsanto argument).

  • Rob Hines

    You seem to be forgetting another thing : if the “pro-GMO” people like yourself attacked studies showing the supposed safety of GMO’s like you do the studies that show possible health problems, there’d probably be nothing left for you to link to. There’s probably all types of flaws in so many of the studies that are pro-GMO, but of course, why would you bring up that point? It doesn’t support your arguments. If you can’t bring yourself to mention anything negative about corporations like Monsanto, which have such a bad past, it’s clear that many people arriving at this site will soon notice that and stop wasting their time, no matter how much you ridicule, talk about the “psychology” of “deniers”, and ignore the inconvenient facts. Maybe you should’ve gone into politics instead. Or maybe you are actually in the right place already. Modern “science”, has become so political after all anyway, especially with all of that cash going around.

    • Strawman argument. Either bring real evidence, in the form of peer-reviewed studies, or this discussion will be endless. You are the denier. You need to bring real evidence to the discussion. Otherwise, why would I waste my time with some rhetorical nonsense based in logical fallacies.

      So, unless you have a Ph.D. in a real science, published in real journals, and you have the guts to change the scientific consensus, this is a ridiculous thread.

      I await real science from you. And please, no logical fallacies. It doesn’t help.

      • Rob Hines

        Nah I’ll just leave you to think about your ignorance of Monsanto. “Logical fallacies,” haha, ok. Yours is an argument from delusion. I pointed out that you’re ignoring how bad Monsanto are and have been, I’ll just simply leave you with that. I could link you several papers, but they’ve already been dismissed by the biotech minions already, and that would just repeat, so no point. It’s all that you people can do, attack, because if you let one study through, maybe the floodgates will open, right? Like I said, it’s like politics. It’s pointless, you people are either completely stupid, bought and paid for, or happily creating confusion for the fun of it. If you went after the studies that support GMO’s in the same way you do with those that have shown problems, you’d have hardly anything to source.

        Yes, I get that you’ll say “I have nothing to source”, I do have things to source, but I know you’ll just dismiss them so won’t waste my time. You’re programmed to dismiss them, you probably don’t even have the willpower to be balanced, you’re so invested in your delusion.

        You’re a lair, and you know it. You can’t have studied this for so long and not seen what Monsanto is doing. It’s ok, we’re not going around in circles because I’m out of here.

        Oh, and have fun with your “logical fallacy” and “psychology” games. At least it makes you appear intelligent to some, right? Goodbye.

        • “Argument from delusion” is not a logical fallacy dumbass. Anything else other than the ad hominem personal attacks. Didn’t think so. NEXT.

      • A comprehensive review of peer-reviewed articles of animal feeding studies of GMOs in Environ Int. 2011 May;37(4):734-42 identified about the same number of researchers raising concerns about GMO safety as those suggesting they are safe. Unless you can prove the article is bogus, this hardly represents a consensus. Compare this with the 2012 study of peer-reviewed articles about climate change by James Powell which found only 24 articles out of 13,950 that rejected the notion of global warming.

        Frankly, I don’t believe you are interested in “real science”. I think you’re an advocate. I say this as someone with a Ph.D. in Organic Chemistry from Columbia University, a two-year post-doc at Harvard in the laboratory of a Nobel Prize winner and as the author of 53 U.S. patents in agricultural chemistry on behalf of a major international agricultural chemical corporation. I worked for that company during the period Monsanto was first introducing Roundup and later their first Roundup-resistant product. We knew it was all about selling more Roundup and that any claims about enhancing crop productivity for the benefit of the public was disengenuous at best.

        • The old logical fallacy of the ad hominem attack. Because you have no evidence, you have to resort to silliness and name-calling. Not sure that really matters.

          And your personal Appeal to Authority (which happens to be you) is laughable and kind of off-putting. But if we’re going to compare dick size by our degrees, well, I guess my janitorial degree from a community college pales. I feel sad. I feel like my dick is much shorter.

          The AAAS and NAS disagree with you. There are climate deniers, evolution deniers and HIV deniers who have PhDs that match or exceed yours. Doesn’t mean they’re right, especially if the consensus is totally opposite.

          BTW, please explain to me how a GMO can harm a human being. Oh wait, you’re an organic chemist. Probably couldn’t identify a gene if it bit you on your long dick.

          My degree happens to trump yours for human physiology by a lot. And I just went to janitorial school. And I did pretty, got straight C’s.

  • Gunadi

    If the AAAS statement is the scientific consensus on GM foods, which is clearly confined to the effects on human health, does this imply there is no scientific consensus on possible ecological effects?

    • The broad scientific consensus (despite the denier claims) is for the safety of GM foods on human health, as you state. Your implication that there is no scientific consensus on ecological effects means that there just hasn’t been enough study done. But given the huge lack of plausibility of human effects, confirmed by real science, there’s nothing that would indicate plausibility of environmental effects. And let’s not play that logical fallacy card, Argument from Ignorance, that since there isn’t a consensus about environmental safety then there could be an environmental issue. There hasn’t been one uncovered yet.

      • Gunadi

        I asked a question and did not present an argument as you suggest. Also the lack of plausibility of human effects has been confirmed by science? So you are saying that there have been scientific studies not only on the effects but on the plausibility of human effects? Now you are making things up. Please offer some citations. Also, in your response you make the same mistake you accuse me of. You imply that because there is no scientific consensus there are no ecological issues. This is science? Finally you touch on an issue that is behind the opposition to GM foods. Because there is no scientific consensus on the ecological effects, people adopt a precautionary approach (e.g. The EU moratorium on GM foods). The precautionary principle is certainly not unscientific and it may just be good policy given the uncertainty of future costs and benefits.

    Okay, “Skeptical Raptor” (oh my, that’s clever), you’re so nasty I hesitate to engage but I do want to say one thing so please, indulge me. Now I know my comments are without gravitas since I have merely an MS degree in nutritional science as compared to your doctorate in hubric studies from UDICK but are you aware that the head of the FDA is from Montsanto? Of course you are and I am sure you have profound insight regarding government policy and the relationship between industry and government based on your confidence in FDA standards. By the way, your “commentary” reminds me of the tobacco industry’s PR which stated until the mid 80’s that smoking does not cause cancer, despite overwhelming evidence to the contrary. Before you whine about the overwhelming evidence you have referenced supporting the safety of GMO why don’t you look just a bit more, particularly for studies coming out of France. Wait, don’t tell me, in your professional opinion commie France couldn’t possibly produce a legitimate research paper. I’ll get back to you with the industry-influenced research you know and love, in the meantime, you keep eating that GMO please 🙂

    • I don’t cater to conspiracy theorists. Who cares where he’s from? It’s cool that someone gave up his corporate career to serve the country. Anyways, the current Commissioner of the FDA is a Harvard Medical School grad who has worked in public health for her whole life, Margaret Hamburg. I guess you’ll have to invent another conspiracy theory.

      BTW, I don’t care one squat about someone’s degree. There are people here who comment who never went to college, and then there are Ph.D.’s and MD’s who studied science their whole life.

      Inventing some passive aggressive statement that you’ve got some low class degree from an online university or whatever is lame as hell. All that matter is 1) you present evidence, 2) you understand what a scientific consensus is, and 3) if you want to go against the consensus, then get off your fat ass and publish articles in real journals that provide evidence against the consensus. Otherwise, your asinine comments about my degree and my world class university education is just immature, ignorant, and evidence of your intellect.

      Oh, the Seralini study? OMFG, you’re an idiot.

      • Rob Hines

        You don’t care that the FDA are so linked with Monsanto, and have been for quite some time now? Yet you preach about “real science”, and ignore the fact that science has been corrupted by corporate funding so much, ok. (I’m sure you have the intelligence to research this and find quite a bit, which makes me a lot more suspicious about what you’re doing here.) Of course, this is a “conspiracy” mindset. Of course it is, because the more you attack people speaking out against GMO’s, the more you switch focus from the arguments and onto “psychology”, the less you have to face the sad truth that corps like Monsanto are up there with the most corrupt on the planet. The fact that you ignore how bad Monsanto is, and also ignore the way that they have links with so many government organizations and scientists that they fund, creates a massive, huge hole in your arguments.

        By ignoring what Monsanto has done, and by refusing to have any doubt about GMO’s, (any long terms studies on Humans in your links back up there?), and your almost infantile notion that science isn’t corrupt when so many other areas of life currently are, you’re the one living in ignorance here, and one day you’ll maybe accept that. The “science” on GMO’s has a long way to go, and no amount of links that you post is going to change that for the time being. Or ridicule.
