Impossible Burger: Industrial Scam with a Side of Glyphosate

A couple of articles have come across my radar lately that are worth noting, and they fit in with some conversations I've been having, both casually and work-wise. Those conversations have to do with genetically modified organisms (GMOs), laboratory-produced synthetic meat products—the industry likes the hygenic "clean meat" label because it doesn't have the "dirty" association with farms and killing animals for food—and glyphosate, the active ingredient in the pesticide Roundup made by Monsanto, which has been found guilty of causing plaintiffs' cancers in three recent trials, as well as being labeled a carcinogen by the state of California.

Impossible Burger.

The articles involve the Impossible Burger, which its manufacturer enthusiastically lauds as "making meat using plants, so that we never have to use animals again. That way, we can eat all the meat we want, for as long as we want. And save the best planet in the known universe." It claims to taste just like meat, too, and to "bleed" (i.e. leak juices) when cooked just like a normal hamburger.

All this good news has the tech-bros in Silicon Valley and the VC dudes weak in the knees and climbing over each other to finance products that can be industrially manufactured by the zillions and sold to a public clamoring for healthy, climate-friendly, humanely produced food.

Aerial spraying of pesticides.

What the manufacturer, Impossible Foods, has neglected to say amid all this hoopla is that the soy proteins used in its burgers are derived from soybeans that were genetically modified to resist applications of Monsanto's Roundup—sold as "Roundup Ready" seeds—that is used to kill weeds that might compete with the soy plants in the field and/or impede harvest. Roundup is also sprayed on fields just before harvest to dessicate, or dry out, the soy plants before harvest.

The organization Moms Across America, with a mission to educate the public about the dangers of GMOs and toxins in the food supply, recently published an article titled "GMO Impossible Burger Positive for Carcinogenic Glyphosate" that describes tests done by Health Research Institute Laboratories showing that the levels of glyphosate detected in the Impossible burger "were 11 times higher than the Beyond Meat burger [a competing lab-produced product]. The total result (glyphosate and its break down AMPA) was 11.3 parts per billion (ppb). Moms Across America also tested the Beyond Meat Burger and the results were 1 ppb.

Monsanto's Roundup with glyphosate, a known carcinogen.

"This new product is being marketed as a solution for 'healthy' eating, when in fact 11 ppb of glyphosate herbicide consumption can be highly dangerous," according to Zen Honeycutt, the founder of Moms Across America. "Only 0.1 ppb of glyphosate has been shown to alter the gene function of over 4000 genes in the livers, kidneys and cause severe organ damage in rats."

It must be noted here that almost no mention is made of agricultural workers and the dangers they and their children face from exposure to this toxic pesticide, which can cause damage during pregnancy and developmental delays in addition to causing cancer and other health issues.

The article goes on to list the ingredients in the Impossible Burger, which it says could contain as much as 80 percent genetically modified ingredients like sunflower oil, potato protein, yeast extract, cultured dextrose, modified food starch and many others in addition to the soy protein.

Another problem with the soy protein in the Impossible Burger is described in an article from the Organic Consumers Association. It states that "in the messy world of soy studies, where 'soy' can be defined as almost anything with soy in it, there are just as many studies showing no or only marginal benefits, and in some cases, potential for harm" from diets high in soy. Contrary to the beneficial reputation of fermented soy products like tofu or miso, these highly processed soy proteins are made from defatted soybean flakes that have been washed in either alcohol or water to remove the sugars and dietary fiber. "Alcohol is the most common process, as it produces products with a neutral taste. But the beneficial isoflavones in soy are removed by this method. Soy protein concentrate has the lowest level of healthful isoflavones—including daidzein, genistein and glycitein—of any form of processed soy."

But the biotech industry isn't taking all this lying down. An article describing the steps manufacturers are taking to undermine media reports states that "the biotech industry is particularly focused on taming controversies surrounding GMOs and the chemicals that are used on genetically modified crops, including Monsanto’s weedkiller glyphosate. The world’s most widely used herbicide, glyphosate is critical for the successful cultivation of GMO corn and soybeans. A recent study found that the chemical’s use by farmers has jumped fifteen-fold since 1996.

"One tactic industry allies employ to discredit questions about GMOs is to narrow the discussion to food safety. Pro-GMO scientists and writers mock experts and critics, by portraying them as loonies who think eating a bag of corn chips is akin to ingesting a bottle of arsenic. But this is a misleading line of attack, since GMO concerns are wide-ranging, including how well they are tested for safety, their impact on agriculture and the ecosystem, and the toxicity of glyphosate."

The article quotes author Michael Pollan as saying, "The industry’s PR campaign to reframe the GMO debate and intimidate journalists through harassment and name-calling has been remarkably successful in my view."

It remains to be seen if the recent guilty verdicts have any effect on people's willingness to subject not just themselves, their children and their pets to these pesticides, but their communities and the air, water and climate that we all depend on.

Pet Food: Best Choices for Pets (and the Planet)

For some time I've been wanting to write a post about pet food, a $30 billion industry in the United States with many of the same problems as our human food system in its dependence on processed food made from corn, soy and grains—most genetically modified, requiring the use of pesticides and herbicides to grow them. With statistics on the incidence of cancer in pets reaching an alarming 50 percent, it is an appropriate discussion to have. This post from owner Christine Mallar of Green Dog Pet Supply sums up many of my own concerns about this industry, and it is posted here with her permission.

You may have heard something online or from your vet about the issue of dogs eating grain-free foods sometimes showing low levels of taurine in their bloodwork. At Green Dog, we’ve had a number of customers who have said that their vet told them to switch to a food containing grains. One local vet in our area just sent out an email about "Heart Disease and Grain-Free Foods," and also advocating the use of "meat by-products" in pet foods, and we’d like to address both of these topics to help you learn more and make educated decisions.

Grain-Free vs. Grain-Friendly Diets

The truth is, all processed dry pet food diets are compromised nutritionally due to high-heat, high-pressure extrusion and the need for starchy carbs to bind them and make those little crunchy nuggets. Critical amino acids like taurine that are found in muscle meats and organs are fragile and very heat sensitive, and so become damaged by processing. Another variable that might exacerbate these diet-related heart problems could very well be the overuse of legumes in dog foods. Some brands use a lot of them because they contain plant proteins that are less expensive than meat proteins, but plant proteins don’t contain those vital amino acids. Large quantities of peas may very well be blocking absorption of those important amino acids found in meat that do vital jobs in your dog’s body like support its heart function. (Article on health problems associated with grain-free pet food.)

One thing that frustrates us is that many traditional vets work closely with brands like Purina and Hills, companies that are eager to use this opportunity to switch nervous consumers back to their formulas that contain corn, wheat, and soy. Some of these well-intentioned vets are simply advising customers to switch to any food containing grains. Please note that foods made with grains also are using plant proteins to save the company money by taking the place of more species-appropriate proteins from meat, and these plant proteins also do not contain those valuable amino acids like taurine, just like in grain-free foods.

Both corn and wheat are high-carbohydrate and high-glycemic ingredients and can also cause food sensitivities and allergic reactions in dogs. We often see dogs with new troubles come to us after having been on a diet like this, and we are able to reverse these new issues when we remove the foods that contain corn, wheat, and soy and switch to kibbles that have higher quality sources of meat proteins.

More importantly, ingredients such as corn, wheat and soy are likely to contain contaminants that don’t cook out.

Glyphosate and Aflatoxins in Pet Food

Genetically modified (GM or GMO) crops are sprayed with large quantities of Roundup—its active ingredient is glyphosate [which in two recent trials was found to have caused cancer in the (human) plaintiffs]—with corn being especially problematic as it almost certainly contains dangerous [and carcinogenic] aflatoxins. These are dangerous grain molds, toxic to humans and animals, even in very small amounts. The most recent stats from 2017 show that 88 percent of all corn tested nationally was contaminated with aflatoxins, and in some previous years (2012) it was 100 percent contaminated. A testing agency stated: "With more than ten years of experience monitoring the occurrence of mycotoxins in livestock feeds, [animal nutrition company] BIOMIN has shown that co-occurrence of mycotoxins (the presence of more than one mycotoxin) is the rule and not the exception." The FDA allows mycotoxins to be at 20 parts per billion (ppb) in pet foods, however, studies show that even small amounts of mycotoxins can be dangerous to pets. From the International Journal of Food Microbiology, Drs. Herman J. Boermans and Maxwell C. K. Leung published the report “Mycotoxins and the Pet Food Industry: Toxicological evidence and risk assessment” in 2007. One of the biggest issues of concern discussed is that existing studies of mycotoxin contamination in pet food overlook the day-to-day consumption of small amounts of mycotoxins; resulting in “chronic diseases such as liver and kidney fibrosis, infections resulting from immunosuppression and cancer.” In 2005 a Diamond Foods aflatoxin recall resulted in 100 dog deaths.

We don’t have a problem with some grains in foods, and at Green Dog we carry a few lines that have ingredients like oats and barley and rice. All of the kibbles we carry generally have a high percentage of their protein content derived from muscle meats and organs and not plant proteins (even the ones that use some peas). However, you don’t have to run to a food containing grains.* The amino acids in all extruded kibbles suffer damage from heat processing. Ask your pet food store what percentage of your pet food’s guaranteed analysis of protein is derived from meat proteins (as opposed to plant proteins). If it doesn't have that information available, you can: 

  1. Call the pet food company and ask this question. If they won’t tell you, consider switching brands.
  2. Look for a baked kibble (as opposed to extruded) as more of the amino acids survive baking intact. Stella and Chewy’s is one baked kibble we carry.
  3. No matter what, consider adding some fresh taurine-rich foods to your pet’s dry food. It’s easy, can be inexpensive, and your pet will love it! See here for suggestions.

Re: Meat By-Products

One thing we take issue with is the statement that "meat by-products” get a bad rap and are actually just good organ meats. Organ meats are desirable ingredients, and are far more expensive than what are generally termed meat by-products. Good organ meats would be listed on the label as their own named ingredient, i.e. “beef liver” or “beef hearts," etc., and would be USDA-inspected and passed for human consumption.

When you look closely at FDA regulations concerning pet food ingredients, meat by-products are defined as rendered product that is legally allowed to be a mix of any species of animal, including animals that “died otherwise than by slaughter." These include animals that died from disease, euthanized animals, condemned or spoiled meats, and roadkill. Rendering facilities are waste management facilities, with separate standards for handling and storing ingredients meant to be rendered. The FDA states clearly that these ingredients are acceptable in pet foods. When looking at your ingredient list, it’s important that you see the species of animal mentioned with the proteins and the fat, i.e. avoid “animal fat” and choose “chicken fat."

At Green Dog, we love human-quality organ meats for pets, and strongly advocate for their use to help supplement naturally occurring amino acids like taurine, cystein and methionine that support heart function, but we avoid by-products in pet foods, as even named ingredients such as “chicken by-products” are not handled with the same safety or quality standards as USDA-inspected and passed meats and organs.

Final Thoughts

It’s true that in a recent update the FDA says that between Jan. 1, 2014, and Nov. 30, 2018, it’s received reports of 325 dogs and 10 cats diagnosed with Dilated Cardiomyopathy (DCM). Most were eating grain-free kibble, but some were on kibble with grains, vegan diets, and some homemade diets. The figures include 74 dogs and two cats which had died. At the same time, as the FDA notes, diet-associated reports of DCM have affected a very small proportion of the estimated 77 million pet dogs in the country. In the update on its investigation, the FDA said that "tens of millions of dogs have been eating dog food without developing DCM" and “based on the data collected and analyzed thus far, the agency believes that the potential association between diet and DCM is a complex scientific issue that may involve multiple factors."
