‘GMOs Decoded’ –Krimsky’s latest screed

‘GMOs Decoded’ –Krimsky’s latest screed

GMOs Decoded is Tufts Professor Sheldon Krimsky’s latest skeptical discussion on the virtues of plant biotechnology. Unlike his previous book, The GMO Deception, Krimsky here appears at first to take a more nuanced approach, by taking about eight of his fourteen chapters to explain the details of various biotechnology issues.

The book opens with a Foreword by nutritionist Marion Nestle, which you can read here in her column. Nestle has never been a fan of biotechnology so her comments are fairly anodyne.

Then, in the Introduction, gives away the game by noting that “there is a strong scientific consensus among elites over GMOs.” He goes on to say that “Although some scientists have declared the debate…over,” referencing Jon Entine’s Forbes article which references von Eenennaam and Young’s trillion animal feed study, This major study in the Journal of Animal Science studies feed records for over 100 billion animals fed either GE or non-GE foods, and found no unfavorable effects on the animals.

Then Krimsky notes that “other scientists declare with equal confidence that there is no scientific consensus on GMO safety.” His reference is to a paper in the trivial non-journal Environmental Sciences Europe, by prominent GMO disinformationists: Nicholas DeFarge, Michael Antoniou from Seralini’s group, and Indian pseudo-science mystic Vandana Shiva, among others. The paper presents no research but merely a report on a petition signed by “300 scientists worldwide.” (I have that list and most of the signatories are not scientists.)

The Seralini problem

Critiques of biotechnology, or colloquially “GMOs,” really was heightened by Giles-Eric Seralini’s 2012 paper in Food and Chemical Toxicology featuring tumor-laden Sprague-Dawley rats: Long-term toxicity of Roundup herbicide and a Roundup-tolerant genetically-modified maize.” Even the title made the objective confusing.  Wayne Parrott’s criticism describes the paper’s problems clearly.

The paper had so many problems from animal husbandry to poor experimental design that protests and a re-review caused the journal to withdraw the paper. It was eventually reprinted (without review) in Environmental Sciences Europe where you can find it now.

Seralini’s group has continued to publish papers critical of biotechnology, all of questionable validity, and many very difficult to follow. His co-workers and colleagues have been publishing these papers ever since, and Brazeau has dubbed them the “Seralini pseudo-science syndicate.” And none of his lab’s papers have been replicated be others.

The footnotes

You can learn a great deal about a book’s approach by scanning the footnotes, which occupy pages 156-181 in Krimsky’s book. It doesn’t take long to discover that the footnotes are larded with 15 references to Seralini’s disinformation machine.

Charles Benbrook who was for a few years at Washington State University, but whose salary was paid by the Organic Center and has close ties anti-GMO activists, appears in 5 footnotes, and his paper (published in a predatory pay-to-play journal) claiming negative impacts of GM crops has been roundly debunked by Brookes, Carpenter and McHughen.

Jonathan Latham, publisher and author of the anti-biotech Independent Science News appears twice arguing that transgenic plants can sometimes mutate dangerously. He has been severely criticized by Katiree.

There are, however, many footnotes to well-regarded sources such as Brown and Federoff’s Mendel in the Kitchen and papers by legitimate scientists like Wayne Parrott and Alessandro Nicolia, for example.

The chapters

The book starts out soberly as an outline of various genetic breeding techniques: traditional, molecular and their differences. Chapter 4 details difficulty in producing the Flavr-Savr tomato and FrostBan  bacteria. Chapter 5 covers herbicide resistant  crops and brings up no-till farming, which can improve soil health. However, it suggests that herbicide resistant weeds may require tilling. However, this has obvious solutions in crop rotation. The chapter also brings up Benbrook’s discredited paper claiming increases in herbicide use that are significantly overstated. This chapter also brings up the IARCs discredited claim that glyphosate can cause cancer.

Chapter 6 fairly and accurately covers disease resistant crops, but in Chapter 7 covering insect resistant crops, Krimsky goes afield in his summary of Starlink Corn, spending  several pages scaring us, only to finally report that there was no evidence that Starlink corn caused any illnesses. Krimsky then cites Antoniou and Robinson from Seralini’s stable to claim GM-fed rats suffered liver and kidney damage in a 3-generation study that you can safely ignore.

Chapter 8 on GMO Risk Assessment makes claims that “scientists differ,” but suffers from a dearth of supporting footnotes on who and what these differences are. There is a lot of “some groups” but “other groups” but little supporting explanation.

Chapter 9 on Contested Viewpoints argues that trans-genes may be placed differently and could result in plants having different properties, including varying toxicity, but cites Latham twice and actual scientists in Kuiper et. al. You have to actually check the papers to see that there is little to be concerned about here. He also raises the question of whether pre-market testing is actually done, as if this is not a requirement for approval. Krimsky also gets “substantial equivalence” wrong, but Kuiper explains it clearly.

  • Substantial Equivalence is a starting point for a safety assessment
  • Make a comparison between the GM organism and its closes traditional counterpart.
  • Identify intended or unintended difference on which further safety assessment should be focused.

By contrast, Krimsky says that a transgenic crop and its conventional counterpart about which toxicology information is known are compared. “When extensively analyzed, if the transgenic crop exhibits no changes …compared to its parent strain it can be treated as substantially equivalent to that strain. After that determination is made, further safety or nutritional concerns are expected to be insignificant.”

This is just not the same idea at all!

The chapter also mentions a 13-week pilot study on the effect of Roundup on the gut microbiome of rats in a study performed by the Ramazzini institute in Italy. While they did claim to find some changes in the microbiome, the Ramazzini institute seems to have a spotty reputation, having been criticized for poor reliability in another recent study on aspartame, and in the glyphosate case, Brazeau criticizes them for finding “results that match their priors but not anyone else’s research.” (They also did a questionable report on cell phone radiation.)

Much of the rest of the chapter deals with worries that have never been found to be an actual problem.

Chapter 10 rehashes all the arguments for labeling GMOs and some of the issues various states have encountered, closing with the fact that Congress passed a “labeling law” that amounts to a QR code you can scan with your phone, and is thus pretty harmless.

Chapter 11 deals with the 2016 National Academies Study on Genetically Engineered Crops. Krimsky admits that the evidence of the report reinforces the fact that GM crops are safe to eat and do not pose any risks. However he carefully picks advantageous quotes to suggest that biotechnology does not improve yields. One would wonder why famers are then willing to pay more for them. If you read through the report or its summary you will find a number of carefully written conclusions suggesting that it is mostly difficult to measure the effects of yield because it is difficult to find identical cropland to compare GM and non-GM crops, and whether the GM and non-GM varieties were true isolines to be comparable. The report also discusses the strategy for preventing evolution of herbicide reisistant weeds and Bt resistant insects.

In fact, the report suggests that in the U.S. and in China, insect-pest populations “are reduced regionally and that this benefits both adopters and nonadopters of Bt crops.” And it is important to note that Bt brinjal (eggplant, or aubergine) has significantly improved farmers’ lives in both Bangladesh and India.

Krimsky also spends 3 pages defending Seralini’s disgraced paper, claiming that was “not a carcinogenicity study” to defend the small number of rats used. In fact, critics have said that Seralini’s paper had no particular objective in advance and he let the S-D rats grow until they naturally developed tumors and published their pictures.

Finally, Krimsky attacks the integrity of the NASEM panel itself, pointing to a reference that claims 6 out of 20 members had conflicting financial interests. Of course that paper is by Krimksy himself.

Chapter 12 discusses the development of Golden Rice, which the author calls a “promise unfulfilled.” It has now been approved by the US FDA, however.

Chapter 13 discusses conflict among scientists regarding GMOs as if it actually existed. The overwhelming worldwide consensus, including every major national scientific association, is that GM crops pose no harm. He mentions “uncertain risks,” and the “GMO divide” which he himself has tried to manufacture. He recycles the canard that “farmers do no own their own seeds” as if hybrid seeds had never before existed, and of course mentions international crackpot Vandana Shiva who questions  patenting living organisms. Oh, and don’t forget “corporate hegemonic control.”

Chapter 14 presents Krimsky’s completely expected, but erroneous summation. He attacks the values of science and “trans-scientific concepts,” (whatever they are!). He suggests that “it’s an evolving story in India,” despite the overwhelming success of Bt brinjal, and questions whether yields actually improve. Of course he trots out Robin Mesnage, one of Seralini’s henchmen to argue that corn (maize) sprayed with Roundup produces different metabolites, and claims farmers have untold economic losses because of unexpected GM contamination.

Conclusion

Krimsky starts out soberly enough trying to explain the various techniques that have been developed and some of their successes. But he can’t help himself, and by Chapter 5 he is back beating the same poor old horse, and gradually slipping more misinformation into each succeeding chapter. Nothing really new here, unfortunately.

Roundup verdict in California: nothing to do with science

Roundup verdict in California: nothing to do with science

You have probably read about the verdict in California where a jury awarded the plaintiff, Dewayne Johnson $280 million in damages because he developed non-Hodgkins lymphoma while working as a groundskeeper and using Roundup.

You never know how juries make their decisions, as attorney and farmer, Amanda Zaluckyj explains. But we can be sure, that science had nothing to do with it. Maybe they chose to disregard the science because they sympathized with Mr Johnson’s severe lymphoma. But, as Monsanto pointed out in the trial, Johnson’s lymphoma was diagnosed some 10 years before he began using Roundup.

johnsons cancer monsanto

Maybe they didn’t  like Monsanto. The Organic Consumers Association, and US Right To Know have been pushing this anti-biotechnology line for years in order to scare people into using their pricier organic products. Henry Miller has even connected these attacks to the Russian government.

But the science is very clear and has been for years. Glyphosate, the main ingredient in Roundup has about the same toxicity as salt or aspirin. It has been in use since 1974 and is incredible effective and incredibly safe.  Here’s one review on toxicity and here’s another on carcinogenicity.

Probably the only actual report of Roundup causing cancer was made by the IARC, a small French research unit, who when they lost their budget, joined the WHO as a small research division. The trouble with that group is that they were not scientifically driven, but politically driven, considering only a few cherry-picked papers out of the hundreds of papers available on Roundup. And their conclusion was driven by lobbyist Christopher Portier, who formerly worked for the Environmental Defense Fund. Portier is not, however, a toxicologist.  So, when the IARC declared that  Roundup was “probably carcinogenic” they were not considering scientific data, but driven by politics.  I wrote about this in detail here.

Soon after this, the WHO overrode the IARC, and, along with the UN, declared that Roundup was NOT carcinogenic, based on available scientific data. The EFSA quickly agreed.

Courtrooms are not a good place for science,  because juries do not try to understand the scientific method or scientific findings, and instead try to connect with the emotions of the case: poor, sick groundskeeper versus large agricultural company. Who would you predict would prevail?

Fortunately, Monsanto is appealing and we hope will prevail against these preposterous claims. You might also read Cameron English’s excellent analysis of this case here.

No, cell phones do not cause cancer!

No, cell phones do not cause cancer!

Let’s start with a homely example. If a friend comes to you claiming to have a wonderful new pudding recipe, made only from grass clippings, your first response would be “how would that work?” You know that grass is really fibrous and doesn’t have a lot of flavor.

So, if another wacky friend comes to you claiming that cell phones cause cancer, you could ask the same question: “how would that work?” Because you know that the microwaves used in cell phones are so low in energy that they cannot disrupt any chemical bonds.  Prominent physicist and educator Bob Park dealt with this in 2001, in the journal article “Cell phones and cancer: how should science respond?

As Park points out, all known cancer causing agents work by breaking chemical bonds, producing mutant strands of DNA. The energy of such elector magnetic radiation runs from low energy microwaves through the visible spectrum, up to ultraviolet and eventually to X-rays, with the energy is determined by the wavelength, with the shorter wavelengths being more energetic. Only at the ultraviolet wavelengths and beyond do the photns that make up such radiation have enough energy to break bonds. Microwaves, infrared, and visible radiation just can’t do it, and thus, cannot cause cancer.

Knowing that one simple fact makes it easy to question alarmist articles like the one in last week’s issue of The Nation, on a conspiracy theory on how Big Wireless made us think cell phones are safe.  The report, by Mark Hertsgaard and Mark Dowie details a conspiracy to shut up cell phone critics, which even if true does not establish the cell phones are dangerous. It is simply another example of The Nation reporting outside its political specialty, but ignoring established science.

But why believe Park and me? The American Cancer Society has a high readable report:  Cellular Phones that comes to the same conclusion.

But what about if you are in a room full of cell phones and make hundreds of calls a day? Is that any more dangerous? What about Michael Cohen’s 16 cell phones? To answer, consider the following thought experiment, which, I think, came originally from Bob Park.

Suppose that Napoleon stands at the Strait of Dover with his soldiers and orders them to throw rocks towards England. No one can throw a rock 21 miles, so nothing much happens. So, thinking he just needs more force, Napoleon brings in several more divisions of soldiers and has them all throw rocks towards England.

What happens? A lot of rocks fall into the water, but none get to England, because none of the soldiers is strong enough to throw a rock 21 miles. The same applies to all those cell phones. None can break a bond so even the whole group can’t cause cancer.

Hertsgaard and Dowie cite a well-designed 2016 experiment by the National Toxicology Program in which rats are raised in specially designed crates where they were irradiated with 2 different levels of cell phone radiation (or none for the control group)  for 10 minutes on and 10 minutes off for 9 hours a day, from birth to 2 years. Some rats got CDMA modulated radiation and some got GSM modulation. The original 2016 report was described in Scientific American, and it raised some concerns.

The final revised 2018 result, after adjusting for litter effects, was that there was no positive association between cell phones and brain neoplasms for female rats, male mice, or female mice. They found an association for male rate and only for CDMA modulation. Further, the irradiated male rates lived longer than the controls. In other words, this appeared to be a random effect of no significance. All of this is explained in detail in an article on Science Based Medicine.

While earlier 2016 preliminary analyses seemed to indicate an actual effect, it disappeared when the statistics were adjusted for litter effects (animals from the same litter would be expected to have similar responses).

So, physics is still true, and alarmism has lost out again. Your cell phones are safe.

Sweet potatoes were naturally made using GMO techniques

sweet-potato-fries-with-sea-56276If you look at the packaging for Alexia Sweet Potato Fries (which are actually very good) you will see “Non-GMO” and that annoying GMO Free butterfly label.  This is called fear-based marketing. We don’t use that scary GMO stuff (whatever that is) in our potatoes. But in the case of sweet potatoes, nature beat them to the punch.

Farmers breed plants all the time to get new, stronger and tastier varieties by crossing them. This is tricky because you usually then have to “back-cross” your new variety with its parents to make it more like its parent. And this can result in exchanging of over 10,000 genes! This was the way the pioneering plant biologist Norman Borlaug bred the wheat that saved Mexico and later India. For this he was awarded the Nobel Peace Prize.

Another way farmers and breeders have used is irradiation of seeds. This is kind of a crude technique, called mutation breeding, but it is how we got the current Ruby Red Grapefruit. You just have to plant the seeds and see what comes up. Then you save the good ones.  You can also perturb the seed using mutagenic chemicals (such as colchicine) to cause it to mutate. This is just as uncertain, but we have gotten a lot of nice flowers and a few vegetables that way.

The last way is using biotechnology to insert just the gene we want for the trait we want. This is the most precise method, but not everyone (except most scientists) is convinced that there aren’t some sort of unknown side effects. They usually use a bacterium called “agro” (for agrobacterium tumefaciens) which is a sort of a ring of DNA called a plasmid. This bacterium can insert genes into plants, and that is where the bulges come from you see on oak trees, called oak galls.

Now if biologists make that ring of DNA longer by including the genes they want in the plant they can persuade agro to do their insertions for them and this is the way most genetically modified crops are made today.

Here’s the news. This wasn’t our idea! That intellectual property belongs to a sweet potato! Virologist Jan Kreuze of the University of Washington in Seattle reported that they examined the genes of some 291 varieties of sweet potatoes from around the world, and found in all of them foreign genes from bacteria. Further, they found genetic sequences analogous to those in agro. And while they found these in sweet potatoes, they did not find them in close relatives.

Now, sweet potatoes are just the swollen parts of the plant’s roots and the authors theorize that this modification is what gives sweet potato plants this bulge; both are lacking from the close relatives. So sweet potatoes did their own “genetic engineering” some 8000 years ago, and farmers selected the plants with the best “bulge” to plant each year. And clearly after 8000 years we can be pretty sure there are no ill effects from eating them.

This is a pretty good indication that such genetic modification is perfectly safe, and every major scientific organization world wide agrees that this is true. You can find declarations from the AAAS, the AMA, and the EFSA.  Every major scientific society and national scientific organization has indicated that GMO foods pose no harm of any kind. Here is a good review in Scientific American by Pamela Ronald. And the position of the American Association for the Advancement of Science is very clear in stating that GMO crops pose no harm.

So, ignore those meaningless “non-GMO” marketing labels, and avoid products making those specious claims when you can. You may actually save money, too.

 

 

‘The Nation” spreads farming misinformation like a manure spreader

DSC_0006The Nation is a venerable  magazine, having been founded in 1865, and for over 150 years has been providing political commentary, mostly on US administrations and events. While it writers skew to the left, this is not entirely the case and major writers have included Henry James, Henry Wadsworth Longfellow, Frederick Law Olmsted, W.E.B. Dubois, E.M. Forster, Emma Goldman, Sinclair Lewis, Willa Cather, H.L. Mencken, Upton Sinclair, Margaret Mead, Mark van Doren, Edna St. Vincent Millay, Bertrand Russell, Pearl S. Buck, Albert Einstein, I.F. Stone, Eleanor Roosevelt, Hannah Arendt, Jean-Paul Sartre, Harold Clurman, Edmund Wilson, W.H. Auden, Anne Sexton, Martin Luther King, Jr., Gore Vidal, and Toni Morrison.

With that cast of literary luminaries, you would think they could handle an issue on The Future of Food, focusing primarily on agriculture.  Unfortunately, the left tends to be agriculturally and scientifically illiterate, and much of what the contributors to this issue say is just plain nonsense.

Danny Meyer

Starting with an interview with noted restaurateur, Danny Meyer, written by food extremist Anna Lappe, we learn that in creating Shake Shack,

Our meat is free of antibiotics and artificial growth hormones; the eggs and chickens we use are cage free; the French fries are non-GMO.

How much could go wrong in one sentence?

  • All meat must be free of hormones and antibiotics by the time it is sold. Small amounts of growth hormones may be used in beef, but it must have washed out of the animal’s system before it can be sold. And you would find 1000 times more estrogen in 8 oz of cabbage than in 8 oz of beef. Hormones cannot be used in dairy cattle, veal calves, pigs or poultry.
  • All neat chickens are always cage free. And while chicken used for eggs can be raised free range or in various kinds of cages, a serious study in the Journal of Poultry Science has shown that the birds do best in conventional cages.
  • And what exactly does non-GMO potatoes mean? “GMO” is a breeding process, not an ingredient. The slogan is just fear marketing,  since thousands of peer-reviewed papers have shown that GM foods pose no harm. The JR Simplot company has developed the Innate Potato which is resistant to late potato blight and  produces lower amounts of acrylamide when fried. Why wouldn’t this be the more healthy offering?  Fear-based marketing based on organic industry sloganeering.

Zoe Carpenter

Zoe Carpenter’s lead in column asks (twice) whether consolidation in the agricultural sector will mean that farmers will pay more for inputs like seeds and earn less. The seed business is not a monopoly. There are any number of suppliers farms can choose from and if they choose a more expensive seed, it is because if performs better for them.

Raj Patel on Fair Trade

We have already written extensively on Fair Trade, which, no matter how well intentioned, has not turned out to be more profitable for farmers. This is because farmers are guaranteed a floor price, and they will sell their lowest quality crops into the fair trade market, and sell their best quality crops on the open market. It also has no effect on how temporary workers are treated. And the idea that organic bananas are produced without pesticides is a fantasy spread by the organic industry. Organic farmers just use organic approved pesticides. And, of course, as Bruce Ames showed years ago, plants generate 10,000 times more pesticides themselves than are ever detected from spray residues.

John Boyd on Small Scale Farming

Boyd echoes the canard that farmers who buy genetically modified seeds can no long replant them the next year. But as Amanda Zalukyj points out, farmers really don’t want to save seeds. It’s a huge effort to clean and save seeds, and this practice “went out the window” with the advent of hybrid seeds in the 1930s. These varieties don’t breed true in the next generation anyway.

Dana Perls on GMOs

Perls echoes disproven claims about GMO crops requiring “massive increases in the use of toxic herbicides.” Much of this claim comes from a discredited paper by Benbrook which failed to take account of the relative toxicity of newer herbicides like glyphosate. However, noted weed scientist Andrew Kniss has studied this issue in some detail.

In summary, this analysis suggests that GMOs have had a positive effect (or at the very least neutral or non-negative effect) with respect to herbicide use intensity and mammalian toxicity…

Perls also makes very unscientific claims that vanillin produced using genetically engineered yeast is not “natural,” because “synthetic biology” is involved. She also claims it drives out 200,000 rain forest farmers. Which do you think is better overall for the environment?

Hacking the Grain- Madeline Ostrander

This genuinely fascinating article about attempts to create perennial grains to replace wheat is well worth reading. However, it starts with the mistaken assumption that large fields of s single crop (which they call a “monoculture”) are somehow bad. Andrew Kniss debunks this in some detail, noting that Pollan and his followers never explain why this is so bad. He admits that all of Ireland was growing the exact same potato, reproduced vegetatively so that there was just a single genetically identical potato grown throughout the country. That is why the Phytophor infestans blight wiped potatoes out so completely.

This is not a problem in grain farming, however, because while there may be many thousands of acres of corn or wheat, they are not all genetically identical.

It is important to recognize that you do not need perennial wheat or corn to avoid tilling the fields, which releases a lot of carbon into the atmosphere, and upsets the delicate layering that good soil should have.  No-till farming is regularly done using low impact herbicides like Roundup (glyphosate) to reduce annual weeds and then plant using a seed drill instead of a plow. You can use glyphosate-resistant seed or not as you wish. I actually use this technique in my home vegetable garden.

The rest of Ostrander’s article is a fascinating description of the development and breeding of a perennial grass, they call “Kernza,” which has the potential to be milled and baked much like wheat flour.  The lead scientist on Kernza domestication, Lee DeHaan is profiles on the Land Institute page, and you can read more about his research here.

“Mass Exposure” by Rene Ebersole

In the worst article in the magazine Rene Ebersole recycles all the discredited canards about Roundup (glyphosate) being dangerous. Ebersole starts with the assertion that an “international scientific committee” ruled that glyphosate is a probably human carcinogen. She is referring to the IARC, a small French group that took refuge under the umbrella of the WHO when their funding ran out.

Unfortunately, the group’s credibility fell, when it was realized that they ruled that compounds were “probably” carcinogenic” without considering any dosage issues. As we noted, they ignored decades of government studies, cherry picking just a few that seemed to fit their agenda. Further, it became known that activist Christopher Portier, who was still working with the Environmental Defense Fund, inserted himself into the deliberations and went about telling European governments of these false findings.

The German Federal Institute for Risk Assessment (BfR)  disputed these findings. There are dozens of studies and reviews showing no finding of genotoxicity or carcinogenicity.  And as James Gurney reported, the papers they cherry-picked were full of scientific weasel words like “induced a positive trend,” and the statistical test “often gives incorrect results.”

And, responding to the IARC report, the European Food Safety Association(EFSA) reviewed studies including those from the BfR and concluded:

“…glyphosate is unlikely to pose a carcinogenic hazard to humans and the evidence does not support classification with regard to its carcinogenic potential according to Regulation.”

More to the point, the IARC report has recently been further discredited, when it was discovered that the conclusions were edited or changed, as summarized by Ridley, and that Portier had received $160,000 from law firms involved in suing Monsanto.  And just yesterday, Hank Campbell reported that the US Congress is so disgusted with these irregularities that it may be considering “pulling the  plug” in future IARC funding.

Ebersole goes on to claim that Monsanto is being sued because Roundup “Caused them to develop non-Hodgkins lymphoma (NHL).” They have no actual evidence, and Derek Lowe, writing in Science explains the difference between hazard and risk,  and concludes that there is little evidence linking glyphosate and NHL.

Finally, Ebersole quotes Carey Gillam who describes herself as “research director for US Right to Know.” Gillam is not a scientist. She was once a journalist working for Reuters, but after producing a steady stream on attacks on Monsanto, she was dismissed and now works for US Right to Know, a propaganda organization supported by the organic food industry. Further, Gillam has just published Whatewash: The Story of a Weedkiller. This book has not been well received among actual scientists, however, who consider it just more of or propaganda.

Ebersole seems to have overlooked the actual science regarding the safety of glyphosate, and also neglected to point out (as Ridley does) that lawsuits against Roundup are becoming a profitable industry for some law firms hoping to extract money from Monsanto. Bad luck, though, that Roundup has been off patent since 2000, and most of it is made offshore.

In conclusion, this is one of the worst issues of The Nation in years, where fact checking has simply gone home for the week, allowing the spread of bad information and bad science.

 

 

Non-GMO oyster crackers: they are really in the soup

Non-GMO oyster crackers: they are really in the soup

We had some delicious clam chowder at one of our favorite restaurants this weekend. Even the oyster crackers were good: until I noticed the label. There was the stupid Non-GMO Project Verified logo with the even less credible butterfly alongside. Look Westminster Bakers, you make a great product, so why sully it with scare tactic marketing?

The funny thing is that Westminster must have just recently added this scary butterfly logo to their packages, because a search for their crackers brings up a lot of pictures without the anti-GMO label. You only find it on their actual company site.

So what does that mean for oyster crackers that only contain 7 ingredients: unbleached wheat flour, water, canola oil, cane sugar, salt, yeast and baking soda? Let’s stipulate upfront that “GMO” is a breeding process for making plants with particular traits. “GMO” is not an ingredient.

The plants: corn, soy, sugar beets, some squash, papaya, alfalfa, and sorghum have traits that allow farmers to grow them more economically and with fewer pesticides. Non-browning apples and potatoes have also been developed. Every major scientific organization worldwide has concluded that these genetic modifications pose no harm. These organizations include the National Academy of Sciences, the AAAS, the World Health Organization, the European Food Safety Association and hundreds of others, that check for people health in every country, they can improve with the help of diet and supplements as kratom powder.

Let’s take a look at the ingredients in these excellent crackers:

  • Wheat – there is no GMO wheat on the market.
  • Salt – Nope
  • Water – Nope
  • Baking soda – Nope
  • Yeast – Nope (there are some genetically modified brewers yeasts, but none used by bakers)

Sugar comes from either sugar cane or sugar beets. Much of the sugar beet crops grown in the northern US are bred to resist herbicides like glyphosate, to reduce the need for plowing and weeding. Further this also reduced the amount of herbicide actually used to less than a soda can full per acre.

 

GMO sugar  ———–  Non-GMO sugar

But sugar is a simply crystalline compound that is easily purified. Above are drawings of conventional sugar and genetically modified sugar. Can’t tell the difference? That’s because there isn’t any. Sugar doesn’t contain any proteins or any DNA to modify: it is just a simple organic compound that can be extracted from cane or beets. Whether the plant was bred to resist one or more herbicides doesn’t matter: the sugar is exactly the same. The idea that there is such a thing as “GMO sugar” is silly. Either way, it is just sugar. The label “GMO sugar” is what we call an anti-marketing label. It is used to scare you away, when there is just nothing there to be scared of. Fear-based marketing is fundamentally dishonest; this is a prime example of anti-GMO hooey!

Canola oil is another funny story. Rapeseed was grown for many years for its oil, used mostly for lubrication. This was particularly valuable in the UK during World War II. However, rapeseed oil had a bitter taste from a series of mustardy compounds called glucosinolates, which may be tasty in brassicas, but not desirable in cooking oils. In the 1970s, Downey and Steffanson of the Saskatoon Research Laboratory laboriously separated the oil part of rapeseeds from the embryo section, and analyzed the oils by gas chromatography, selecting the seeds with the lowest glucosinolate and erucic acid concentration. They planted and crossed these seeds to produce a new plant that produced Canada Oil, or canola for short.

Soon herbicide resistant versions of canola plants were developed by mutation breeding and natural selection. This was very important, because you didn’t want to include the old rapeseed plants in your oil and if they could be killed while keeping the canola plants unharmed it would make growing canola much more economical.

Later glyphosate and glufosinate resistant plants were developed by the usual biotech means, and were made available. The funny part is that canola plants are absolutely promiscuous, and the pollen can blow for miles. This means that there is a good chance that every canola plant in North America may be resistant to these herbicides and thus, by the lights of the idiotic Non GMO Project, a “GMO plant.” So basically all canola oil in North America is GM. And who cares? There is no protein, no DNA in canola oil so it doesn’t matter.

 It’s just another anti-marketing label. 

Now, there is some canola oil available in the Netherlands that is carefully produced to assure its “non-GMO-ness,” but who cares? Does Westminster buy this? Who knows? Or cares?

Westminster Bakery is almost 200 years old and is justifiably proud of their history and traditions. They claim to be using “the same basic, wholesome ingredients” as their Master Baker devised 200 years ago. Call this marketing hyperbole, though, since canola oil is only about 43 years old.

Organic Consumers Assoc: ‘worst organization in the world’

Organic Consumers Assoc: ‘worst organization in the world’

I received this telemarketing call Friday evening. It came from an 818 number that seemed to be from Pomona, California, and the caller ID said “Organics Fund.” This appears to be the Organic Consumers Fund, a fund-raising arm of the Organic Consumer’s Association. They apparently called to lie to me some more about GMOs.

Alex: “Hello, this is Alex, and I’m calling from the Organic Consumers Fund.  We’d like to thank you for your support [I never gave them a dime].

“We now have a national GMO labeling bill, but it just isn’t enough. Manufacturers only have to put a QR code on the package. We think the information should be spelled out.”

Me: “You mean you want to scare people with some misleading label?”

Alex:  “We think that consumers have a right to know what is in their food.”

Me: “You do know the ‘GMO’ is a breeding process, not an ingredient, don’t you?”

Alex: “Yes, and people deserve to know that this was used on their food.”

Me: “And do you realize that there are thousands of technical papers concluding the GM food poses no harm?”

Alex: “We think people should be able to decide for themselves.”

Me: “So you want to use these labels to scare people into buying overpriced organic foods?”

Alex: “We want people to be able to make up their minds.”

Me: “And decide to spend money on expensive foods? What else have you got?”

Alex: “We also have a campaign to save the declining bee population.”

Me: “You do realize that the bee population has been growing for the last seven years, don’t you?”

Alex: “Well, thanks anyway.”

The Organic Consumer’s Association

This group, led by crackpot food-scare activist Ronnie Cummins has been spreading misinformation about biotechnology for years, and sends wildly inaccurate newsletters almost weekly making unjustified claims about the dangers of GM foods and scary nonsense about Roundup. You would not be surprised to discover that the preponderance of their budget comes from contributions from organic food companies such as Stonyfield Farms, Horizon Organic, and Organic Valley. Their sole purpose is to promote organic food sales by slandering biotechnology and anything else not organic.

While the OCA continues to hammer away about the “dangers of GMOs,” the overall scientific consensus is that they pose no harm. That is the position of every major scientific organization in the world, including the WHO, the AMA, and the EFSA. And for more on who funds GMO denialism, read Michelle Miller’s excellent piece here.

On honeybees

They OCA does have a crazy 2014 position paper claiming that “GMOs are killing birds, bees and butterflies,” but it is complete nonsense. Colony collapse disorder peaked in 2006, but as this Washington Post article explains, bee populations have risen each year since then. The article conflates GM seeds with neonicotinoid seed coatings, and while neonicotinoid insecticides can harm bees, they are not a significant contributor to bee deaths, according to the USDA. The major causes of bee deaths are parasites like varroa mites, pathogens like nosema and European foulbrood, and poor nutrition when bees are moved from one monocrop area to another. Data showed no consistent relations between pesticides and CCD-affected colonies.

The worst organization in the world

In addition, the OCA has taken a consistent and utterly unscientific position toward vaccination, it is an accomplice in persuading immigrants to avoid vaccination.

As reported in the Minneapolis Star-Tribune, a cluster of Somali immigrants near Minneapolis became concerned about the apparent incidence of autism in their population. Some asked discredited (and disbarred former doctor) Andrew Wakefield to speak to the Somalis about his entirely debunked idea that vaccines could cause autism. This theory was thoroughly debunked in a 2004 report by the National Academies of Medicine and by the Center for Disease Control.

However, a weekend misinformation session attacking vaccines including speakers from the Organic Consumers Association who have absolutely no qualifications to speak on this topic, but are very good at scare tactics.

Statistically, it turned out that the autism rate among Somali children was no different than anywhere else in the world, but because of these scare tactics, nearly 60% of Somali 2-year olds have not had their MMR vaccine, and so far 68 cases of measles have been reported in Minnesota, (58 of them in Hennepin County). Measles is one of the most contagious childhood diseases, and about 1 in 20 children with measles get pneumonia and this can lead to death.

Any organization that spews this antivaccine nonsense to a vulnerable population with less access to good medical facts, deserves the epithet of “Worst Organization in the World.”

And an organization that consistently lies about food safety is no better.

 

 

Teaching organic farming in the classroom

Teaching organic farming in the classroom

According to the California Foundation for Agriculture in the Classroom grants of up to $1000 are now available for teachers to “creatively enhance the understanding of organic agriculture for kindergarten through eighth grade students.” The purpose is to integrate organic agriculture into regular classroom instruction. The grants are jointly supported by the California Certified Organic Farmer’s Foundation, and the application deadline is May 15, 2017.

From the scientists’ point of view, teaching students about organic agriculture would be intriguing because while historically, hyperbaric oxygen therapy for stroke, experiments led to the procedures, organic farming is essentially pre-scientific and much is based on the naturalistic fallacy.

However, there is a lot to be learned by studying the ideas and best practices of organic agriculture, and herewith we present an outline for an ideal curriculum.

Indore

Much of the earliest work by Sir Albert Howard at the Indore Farms he supervised in India had to do with the development of compost from vegetable and animal waste, and his first book in 1931, The Waste Products of Agriculture may have been his most important work. Howard noted that decomposition of compost only took place at neutral pH and added lime to achieve this. He believed that good soil aeration and quality humus were all that one needed to prevent disease, which was not supported by later scientist’s work, and his book, An Agricultural Testament contained a number of such ideas which caused him to lose support among botanists.

Sir Albert correctly believed that understanding of the mycorrhizae that lived on most plant roots was important and should not be left to mycologists, but his attacks on overspecialization in agricultural science as well as flaws in his later theories caused him to lose much of his initial scientific reputation, but this only increased his stature among non-scientists.

Lady Eve Balfour

Lady Eve Balfour was one of the first women to study agriculture at a British University and upon graduation she used her inheritance (she was part of the prominent Balfour political family) to buy farm land in Haughley Green in Suffolk, where she began experiments comparing her organic methods with conventional farming methods. Many of her experiments were published in her book The Living Soil in 1943.

Lady Eve was also the founder of the Soil Association, which although small in size, is a major proponent of organic farming in Britain, and she eventually donated her Haughley Green farms to the Association. She also attempted to moderate some of Sir Albert Howard’s extreme positions, but because of some of her other extreme spiritualist positions, Howard refused to join the Soil Association.

The Soil Association has also taken some extreme positions that are unsupported by science, suggesting that animals be cared for by homeopathic means (which cannot possibly work) and taken extreme positions on genetically modified crops which have no scientific basis.

J.I. Rodale

In the United States, Jerome Cohen, writing under the pseudonym of J. I. Rodale, took up promotion of organic farming and gardening with his Rodale Press and Rodale Institute, beginning in 1948, with his book The Organic Front, published by his own press. While Rodale promoted organic farming tirelessly, his views were hard to take very seriously because of his huckster style of writing:

Along comes your scientific agronomist, who should know better, but who recklessly throws a monkey wrench into this microbial universe, by dousing it with strong, corrosive chemical fertilizers. He believes that the conveyor belt method must be introduced into every aspect of farming.

Rodale took on all sorts on anti-scientific views, suggesting that the polio vaccine was a bad idea, and that rimless glasses and salt water cause cancer. He was also a racist. While he boasted that he would live to be 100, he died at 72, bizarrely during a taping of The Dick Cavett Show, although that episode never aired.

Rodale’s has also undertaken a study of organic versus conventional farming, which they published in a glossy brochure, but have never published in any peer-reviewed journal. An article by Pimentel and colleagues in Bioscience analyzes their findings: that organic and conventional farming techniques have similar yields and that in drought conditions, organic crops may do better. Pimentel also examined the economics and found that the two systems generated similar income, but only if you include a 10% organic price premium.

In another recent trial, they rotated their organically grown crop out and planted other soil enriching crops in 2 of the 3 years, and compared the yield with conventional crops grown without rotation. This was hardly a comparable trial.

The National Organic Program

Until the year 2002, farmers choosing to use organic techniques followed one of several sets of standards, but encouraged the USDA to set nation-wide standards so that organic crops would be comparable. The Agricultural Marketing Service within the USDA codified these standards as the National Organic Program, carefully noting that

Our regulations do not address food safety or nutrition. 

While the general fiction put about by the organic industry is that organic crops are grown without pesticides, this is demonstrably untrue, as there are quite a number of permitted substances listed as permitted. This is discussed in some detail by Porterfield.

Pesticides

Some consumers think that organic foods are somehow safer because they are not grown using synthetic pesticides, but plants make their own pesticides all the time and most of the synthetic pesticides in use are similar to the ones plants already make: toxic and carcinogenic in large quantities. But as Bruce Ames has shown, the plant-made pesticides occur at 10,000 times the concentration as the traces of pesticides added during farming.

Organic nutrition

You might think that organic crops grown with minimal pesticides and so forth might be more nutritious, but research has shown that there is essentially no difference. Dangour and coworkers systematically reviewed articles on nutrient content and found that “here is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs.” Similarly, Brevata and Smith-Spangler “found little significant difference in health benefits between organic and conventional foods.”

Organic Yield

Since organic rules prevent the use of synthetic pesticides and fertilizers, you might ask if the yields differ between organic and conventional crops. There are a number of research articles indicating that organic yields are 50% to 80% of those from conventional farming. The diagram below is from de Ponti’s article “The crop yield gap between conventional and organic agriculture.”

COmparison yields

A similar gap was reported by Seufert. DePonti reported an average 80% organic yield and Seufert a 68% yield. And, the USDA’s report on yields was only a little better.

Carbon Footprint

When you plant and grow crops, and harvest them, you are taking away nourishment from the soil. You need inputs to replace those nutrients. In organic farming, this is usually composted manure and other plant debris. But the composting process itself produces greenhouse gases, as Savage notes. Farmers typically apply about 5 tons of composted manure per acre. In fact, the greenhouse gases generated for one acre are equivalent to those generated in manufacturing enough fertilizer for 12.9 acres. This doesn’t seem to be scalable.

Organic Farming causes more pollution

A study at Ben-Gurion University studied the groundwater runoff in a group of new greenhouses, some using manure fertilization and some using drip fertilizer irrigation. They monitored a zone well below the roots and just above the groundwater for nitrogen contamination, and found that nitrogen pollution in the groundwater was 10 times as much in the organic greenhouses as in those using drip irrigation to fertilize the plants.

No-Till Farming

One of the greatest advances in soil maintenance has been no-till farming, where the ground is not plowed up and turned over every season. When you use crops that are resistant to herbicides such as Roundup, you can kill the weeds before planting and plant using a seed drill without disturbing the soil. This preserves the soil structure and prevents soil runoff. Unfortunately, genetically modified crops that are resistant to herbicides are not currently permitted by organic standards. If soil care is important, this standard needs to be changed.

Organic Marketing

Organic foods are marketed throughout the United States by the Organic Trade Association, and the Organic Consumer Association (which regularly spreads misinformation). The definition of “organic” in the US is products “produced without the use of toxic and persistent pesticides and synthetic nitrogen fertilizers, antibiotics, synthetic hormones, genetic engineering or other excluded practices, sewage sludge, or irradiation. “ Since a number of pesticides have been approved for organic use, this is clearly misleading. The Environmental Working Group also is a major promoter of organic products, through its “Dirty Dozen,” which attempts to paint pesticide residues far below danger levels as being unsafe. It also clearly contradicts the findings of Bruce Ames we discussed above.

Thought Questions for Students

  1. What advantages do you see in organic crops?
  2. Are you concerned about pesticide levels on conventional crops?
  3. Why does the organic industry say that no pesticides are used?
  4. If a farmer has 1000 acres of farmland, and hopes to grow 160,000 bushels of corn, how much corn would he be able to grow if he switched to organic methods?
  5. If a farmer wants to make the same profit, how much would he have to raise his prices to grow organic corn on the same amount of land?
  6. Farmland is expensive. Would the farmer be justified in buying more land to grow the same amount of crops? Do you think there is unused farmland he can buy?
  7. In this article, Henry Miller argues that organic farming isn’t sustainable. Do you agree?
  8. In this article, Roger Cohen refers to organic farming as a “fable.” Is that fair?
  9. If you have a limited budget for buying food, as most of us do, would you be willing to pay 10% more for organic foods? How about 50% more? Why?
  10. Organic farmers can reduce their carbon footprint by using an Anaerobic Digester to compost their manure. How much do they cost? How big a farm do you need to pay for one?
  11. Roger Cohen argues that “organic” is actually just an ideology? Is that an exaggeration?
  12. How else could no-till farming work?
  13. By 2050, we project that only 2.5% of US cropland will be certified organic. Is that enough?

The best 2016 science and pseudo-science stories

Science

Gravitational Waves. One of the most striking scientific discoveries of 2016 was the observation of gravitational waves. Predicted by Einstein’s theories 100 years ago, ripples in space-time were finally observed last year by physicists at the  Laser Interferometer Gravitational-Wave Observatory (LIGO), using instruments at Hanford, Washington and Livingston, Louisiana. They announced that they had indeed observed this waves as two black holes spiraled into each other 1.3 billion light years away. The Advanced LIGO systems were completed only a week or so before this black hole collision took place, but they represent a long term investment by the National Science Foundation, and design work done by nearly 1000 scientists. Funding was also provided by Germany (Max Planck Society), the U.K. (Science and Technology Facilities Council, STFC) and Australia (Australian Research Council).

Ebola outbreak over. The WHO declared that the Ebola outbreak in West Africa is at an end and that all known chains of transmissions have been stopped. Flare-ups may still occur and monitoring will continue. In addition, a promising Ebola vaccine has been reported in The Lancet.

Citrus greening. Citrus greening disease attacks orange trees, causing green, inedible fruit, and is spread by the Asian citrus psyllid. It is spreading widely in Florida as well as in Texas  and even California and research into controlling it is in high gear. Essentially, you have to find or create trees immune to the disease, and that is what has been done at the University of Florida. Researchers report having herpes simplex I symptoms a long term and expensive solution, but at least some approach has been “fruitful.”

CRISPR. The gene editing technology CRISPR came into its own in 2016. This technique allows scientists to edit genes without inserting foreign material, using the Cas9 enzyme. Scientists Jennifer Doudna at UC Berkeley and Emmanuelle Charpentier of Umeå University in Sweden found that they could exploit the Cas9 protein by feeding it a pattern of RNA. The Cas9 would then seek out this pattern and snip out that pattern in any genome it was presented with. Related work showing that this could be done in mice was published about the same time by Feng Zhang of the Broad Institute.  You can read a very good explanation of CRISPR/Cas9 by Brad Plumer and Javier Zarracina here. This simple, and relatively cheap technique can be used to create new foods, treat diseases. This follow-on article suggests some of the further advances that CRISPR might be used for, including cancer and Alzheimer’s treatments. If you suffer of any health issues such as anxiety or depression you can find kratom powder for sale online wich is a natural drug that van help you.

Of course, which of the two groups (Berkeley and Broad Institute) have the patent rights to CRISPR is now the subject of an interesting court case, explained here by C&E News.

Homeopathic medicines. Homeopathic “medicines” are usually substances diluted so far that no active components remain. The FTC issued a new Enforcement Policy on Marketing Claims for Homeopathic Drugs.  Essentially, companies must have actual scientific evidence of their efficacy for any health-related claims they make.

Pseudo-Science

How do we do science? Science is the result of a collection of measurable observation under careful control, and usually represents many observations by many research groups. Science is different from politics, where various philosophies can lead to different conclusions. Science is not a set of beliefs, it is a system of careful studies, reviewed by others and published in major technical journals. The results of scientific studies may result in corrections over time: science is inherently self-correcting, but it is not dependent on scientist’s personal political or moral outlooks.

Further, the idea that science can be suspect because of who funds it reveals considerable naivete about how research grants are obtained and how research is actually done. Professor Allison van Eeenenaam of UC Davis Animal Science explains this very well in this excellent article.

Vaccines: Andrew Wakefield was a gastroenterologist who published a fraudulent paper in 1998 claiming that the MMR vaccine could cause autism. This paper has been refuted many times (and retracted) by careful studies and Wakefield was barred from medical practice. Nonetheless the rumors caused by his crackpot paper, has done considerable damage, as too many people believed the rumors that vaccines were somehow dangerous. In fact, it was demonstrated that Wakefield’s paper was an elaborate fraud, designed to make money.  The CDC firmly notes that all research has shown that vaccines do not cause autism, citing the supporting research.

Nonetheless, there are pockets of non-vaccinating families, often living near each other which represent a serious health hazard.  Organizations of non-vaccinating parents have formed, and even have a Facebook group!  Clusters on such parents are sure to spread disease and it is not unreasonable to ask your child’s friend’s parents if their child is vaccinated before allowing them to play with your child.

This is essentially science denial based parenting and it has been difficult to break through, although more and more pediatricians are refusing to treat children whose parents refuse to vaccinate them.

This non-vaccination of children is supported by pseudo-science based practitioners such as naturopaths, who should know better. And this has led to Wakefield making a propaganda film called VAXXED, which purports to give some support to this practice. The film has received scathing reviews, notably by Dr Paul Offit , co-inventor of the rotavirus vaccine, and by the Washington Post.  Nonetheless, some stars in the entertainment industry still claim to these disproven claims.

But to bring us up to date, we just learned of an article by an actual doctor at the Cleveland Clinic, Daniel Neides, who seems to have jumped onto the pseudo-science bandwagon and attempts to connect vaccines and autism, despite overwhelming evidence to the contrary.  Today, the Cleveland Clinic apologized for Neides column and promises discipline. However, the column is still there spreading misinformation. We would suggest termination of Neides at once,

But not to make you think the Neides is along in this crackpottery, the ever-reliable lunatic Mark Hyman (MD?)  has said much the same things, and also claims staff privileges at the Cleveland Clinic.

Organic foods

Organic foods are spreading through supermarkets like tribbles. They are a high-profit class of foods, marked up by both the farmers, and the grocers, so they have every reason to expand their availability. Some stores tart up their organic aisles with special flooring to make you think of “luxury.” But “organic” is a marketing term, as was explained by Agriculture Secretary Dan Glickman when the National Organic Program was announced. It does not say anything about food safety, nutrition or quality. It is  a series of agricultural practices based primarily on prescientific ideas about farming.  Organic trade groups continue to trumpet the lie that organic crops are “free of pesticides,” when the USDA allows dozens of pesticides to be used on organic crops.

And in a 2009 review by Dangour, et. el., they found no nutritional differences between organic and conventional crops. A similar study in 2012 by Smith-Spangler found much the same thing. And as far as pesticide residues go, Bruce Ames seminal paper shows that the pesticides manufactured by the plants themselves are 10,000 times higher in concentration than any agricultural pesticide residues, and thus these residues are more or less irrelevant.

Organic crops also have significantly lower yields, which is part of the reason they cost more. Typically organic crops yield 60-80% as much per acre as do conventional crops. They also are less environmentally friendly.  Organic is not in any way “better.” In fact, writing in Forbes, Henry Miller calls it a “colossal hoax.”

GMO Crops

Genetically modified crops have been in use in many countries for nearly 20 years now, and there has not been a single verified case of any sort of harm to humans or animals in that time. In particular the study of 1783 papers by Nicolia and the billion animal study of van Eenennaam have laid this canard to rest permaenently.

However, the organic industry has mounted a continuous scare campaign about the dangers of GM crops, leading to mendacious labeling such as “GMO free,” when in fact “GMOs” are not an ingredient but a breeding technique. The idea that there is any difference between animals fed GM crops and those fed conventional crops is simply absurd: there is no detectable difference of any kind.

In fact, just like “organic,” the “GMO free” label is a marketing label, attempting to extract more money from consumers by scaring them. The only result of this campaign is higher prices. But because of this relentless scare campaign, only 37% of the public believe GMO foods are safe to eat according to a Pew Research Center survey, while 88% of scientists do. And, in fact, there is a generation gap here as well with millennials more likely to seek out on GM foods. This has led to the ridiculous claims such as those by Hunt’s that you won’t find any GMO tomatoes in their products. That’s because there are no GMO tomatoes on the market!

Climate change. The year 2015 was the warmest on record. The year 2016 was likewise the warmest year on record. Virtually all climate scientists are convinced that climate change is occurring and caused  by humans, and that if we do not make significant modifications in our use of carbon-based fuels, the Earth will end in disaster, and fairly soon. Already, the ocean regularly invades the sewers of Miami Beach. It won’t be long until coastal flooding begins to make cities less habitable.

The Republican Party in the United States is the only major political party in the world who pretends to deny these obvious scientific facts, both because of lack of interest in science and because of their funding by the energy industry.  As Upton Sinclair has written,

“it is difficult to  to get a man to understand something, when his salary depends on his not understanding it.”

 

 

 

Are GMO producers covering up ‘just like’ Big Tobacco?

corntassels2016One of the popular slogans of anti-GMO protesters has been that there is a “cover-up” going on by GMO seed companies about the actual harm of GMO crops, just like the kind of cover-up that Big Tobacco carried out for 40 years on the dangers of smoking. You will hear this sort of talk from Dave Murphy from Food Democracy Now, who can sound pretty extreme in print (see this article in the Huffington Post) but when interviewed on MSNBC sounds somewhat more reasonable, even while talking through his hat. (Recently the Huffington Post was rated the worst anti-science web site by Skeptoid.)

However, in that interview, the best e cigarette companies are engaged in “cigarette science,” and not telling the “real truth.” The trope that a science cover-up on GMO crops is going on just like Big Tobacco carried out is common in anti-GMO protest signs and literature.

Tobacco history

We went back and looked at some of the history of the science on tobacco smoking and lung and heart disease. As more states decide to legalize hitman glass or medical marijuana, cannabis is becoming more accessible to a broader range of people, and gaining mainstream appeal. For new patients or novice users who can’t roll a joint, don’t want the mess of grinding up bud, or would rather not smell like weed, vaping offers a convenient, discreet, and tidy alternative. Most people who have tried vaping they stick to it because its healthier and tastes better, I recommend you to try out best selling e juice. Surprisingly, the research goes back to at least 1950 (1), where the authors found that smokers were substantially more likely to develop lung carcinoma. This was one of only two papers on this subject in PubMed in 1950, but the number grew in subsequent years to hundreds and then thousands of papers per year, all pointing to the same conclusions. Visit Medpot for the most reliable resource of medical plants.

So, in fact, the carcinogenicity of cigarettes was well known over 60 years ago, while it may have been discounted publicly by tobacco companies, there was no cover-up at that time. What is in e juice products? E-juice is the liquid put in vaporizers that creates the vapor itself. It can be made with nicotine, and it can be made without nicotine, but it really depends on the preference of the person.

However, when people began to ask questions about the dangers of second hand smoke (“passive smoking”), tobacco companies took an aggressive approach to neutralize the impact of this research. While Schmidt (2) indicated that the carcinogens in passive smoke were a serious problem, Grandjean et. al. suggested that there was unlikely to be a problem, but by 1981 researchers were pointing towards benzo(a)pyrene as a prime culprit in tobacco smoke. (4)

In 1998, as part of the resolution of a lawsuit by various attorneys-general against tobacco companies, the Tobacco Master Settlement Agreement resulted in significant funds being transferred to the states and the tobacco companies ceasing various marketing practices (check another kind of health-related lawsuit at http://sideeffectsofxarelto.org/current-xarelto-lawsuits/). At the time, the entire archives of the Tobacco Institute and related front organizations became available to researchers.

Because of these documents and the many papers that have been published about them, we now know that the tobacco companies conspired to cover up the harm they knew was being caused by second hand smoke. They also used their law firms and advertising agencies to recruit apparently unbiased scientists to tout their points of view expressing skepticism about the dangers of second hand smoke.

In 2000, Ong and Glanz (5) described the tobacco industry’s efforts to discredit second hand smoke studies, and Drope and Chapman(6) described how this was done by reviewing tobacco industry documents. And the tobacco companies’ law firms and agencies constructed the term “junk science” to try to refute some of these studies as Ong and Glanz noted in 2001 (7).

Perhaps most disturbing was the industry’s attempts to recruit (and pay) independent scientists to repeat industry talking points. The scientists’ papers would still indicate that they were being supported by tobacco industry groups, but as Bero, Glanz and Hong revealed, this wasn’t that hard to get around, as they show by detailing payments to one scientist who published such papers. (8)

A complete history of the tobacco industry’s second hand smoke cove-up was published online by PR Watch.

Development of GM Crops

There are two major types of GM crops in wide use in the US and other countries: Bt maize (corn), cotton, potatoes and tobacco and Roundup resistant soy, corn, sorghum, canola, squash, alfalfa and sugar beets. Roundup-resistant wheat has been developed and found to be safe, but is not being marketed.

In addition, there are ringspot-resistant GM papayas, non-browning Arctic apples and the non-browning Simplot potato, as well as Golden Rice with Vitamin A bred into the plant to combat blindness in vulnerable populations.

Bt insecticides

The bacillus we now know as Bacillus thuringiensis was, according to a review by Je et. al. (9) discovered originally in Japan in 1901 by Ishiwati and rediscovered in Germany by Berliner in 1911 (10), when he isolated it from flour moths.

Bt was found to be toxic to various Lepidoptera that were known to be crop pests and it began to be used in France in 1938, (11) and interest in its use as an insecticide more broadly was due primarily to Steinhaus.(12). There are now a large number of varieties of the Bt, specific to a number of different insect pests. It was found by Angus (13) that during sporulation, it forms a crystalline protein that creates the toxicity.

The important breakthrough in Bt research was when Gonzalez (14) reported that the genes that coded for the crystal proteins were located on separate cell sections called plasmids, paving the way for the cloning of these genes and eventually for insertion of these genes into plant material. The first genes isolated coded Bt toxic to the tobacco hornworm (15), and soon several groups began creating transgenic plants with various Cry genes inserted. The first to reach the market was Bt cotton (16).

Koziel (17) and a dozen coworkers from Ciba-Geigy described the field performance of transgenic maize in 1993, and commercial Bt corn followed soon after the cotton.

Once the Cry genes which coded for various strains of Bt were inserted into foodstuffs, concern was expressed regarding their safety. Numerous independent short and long term studies have shown these foods to be completely safe, however (18, 19).

Roundup

Roundup or glyphosate herbicide was discovered and patented by Monsanto chemist John E Franz in 1970 (20). It’s effectively made by combination of glycine and phosphonic acid, hence the name shortened from glycine phosphonate. It is a contact herbicide, used to kill emerging weeds and is not used as a pre-emergent weed killer. Duke and Powles, in a mini-review (21) have called it a “once in a lifetime herbicide.” Franz received the National Medal of Technology (1987) and the Perkin Medal (1990) for this work.

Even before the development of Roundup resistant plants, Roundup was used by farmers to clear the fields before planting, obviating the necessity of tilling. Glyphosate is of extremely low human toxicity, comparable to aspirin or baking soda, and binds to the soil while it decomposes, so water supplies are not at risk. All the commercial patents have now expired, and it is made by a large number of companies.

Steinrucken and Amrhein (22) reported in 1980 that glyphosate killed plants by inhibiting synthesis of the enzyme 5-enolpyruvylshikimic acid-3-phosphate synthase, (ESPS) which is critical for the synthesis of the  aromatic amino acids phenylalaninetyrosine and tryptophan. If researchers could interfere with this process, they could create plants that could resist glyphosate.

After several years of experimentation in a number of groups, Klee, Muskopf and Gasser at Monsanto reported the creation of a glyphosate resistant petunia (23). This technique resulted in a general method for creating glyphosate resistant plants by cloning a gene that encodes ESPS and inserting it to various plants. Patents on this were filed in 1990 by Shah, Rogers, Horsch and Fraley (24). Fraley recently received the World Food Prize for leading this work.

Related approaches continued for some years and the first glyphosate tolerant soybeans were introduced to the market in 1996.

Research on Safety of Transgenic Plants

Substantial research on the safety of each of the genetically modified plants has been conducted and published by research groups inside and outside the various seed companies. A complete list of nearly 6oo peer-reviewed papers attesting to the safety of transgenic crops has been compiled and published by the Biofortified web site (25).

All of these papers are published in major peer-reviewed journals and thus as an aggregate represent the best scientific knowledge on these systems. Among these hundreds of papers representing thousands of experiments, there are really only two papers reporting health problems from genetically modified crops.

One of these, the paper by Giles-Eric Seralini (26) is the paper most frequently referenced in this regard. While Seralini and coworkers claimed to find that rats fed transgenic maize developed tumors, the Sprague-Dawley rats they used all develop tumors at the same rate as they observed. The paper has been denounced by dozens of scientists for poor experimental design and statistics. The European Food Safety Authority (27) published a final assessment, calling the study of “insufficient scientific quality for a safety assessment.”

Forbes contributor and molecular biologist Henry Miller and biochemist Bruce Chassey published a critical article of Seralini’s work as well (28).

The other recent paper purporting to find dangers in feeding transgenic crops to animals was published by Judy Carman, et. al, (29). Published in a low level on-line journal supported by the Organic Federation of Australia, and not even indexed in PubMed, it is of little scientific validity, and was immediately criticized by scores of scientists.

Carman’s study fed pigs either transgenic or conventional maize for 23 months and then examined their stomachs after slaughter. They claimed that GM-fed pigs had more inflammation, but their own tables show the opposite. Critics (30) also noted the visual inspection of stomachs is not the same as an actual histology study, and probably was meaningless. If you want to read the full info via this guide, visit Kratom News. But most significant, FSANZ, the Food Standards Agency of Australia and New Zealand concluded (31) that the data “are not convincing of adverse effects due to the GM diet and provide no grounds for revising FSANZ’s conclusions.”

Comparison with Tobacco Cover-ups

In the case of tobacco companies, the cover-up was clear, because independent research had established and continued to establish the dangers of smoking and of second hand smoke, while at the same time, tobacco sponsored research was attempting to suggest alternate explanations for the observed diseases associated with such smoke.

By contrast, there are not really any credible studies from any source showing any damage to animals (or people) from any current transgenic crop. There is no sign of any coverup of evidence or papers adopting alternate hypotheses, because no negative results have been found. Nor are there conflicting conclusions presented by independent studies versus industry funded studies.

Consequently, there is no analogy between the near-criminal behavior of the tobacco companies and the relatively open research environment in which transgenic crops have been developed. There just doesn’t seem to be any evidence of a conspiracy.

The only evidence we find of mendacity and conspiracy is in Seralini’s and Carman’s papers, which have been found to be wanting of solid, believable science. And strangely enough, the web site gmoseralini.org and gmojudycarman.org have an identical design and style. And as Byrne and Miller noted (32), the organic industry is spending upwards of $2 1/2 billion opposing transgenic crops.
