Should Humans be Concerned About Glyphosate?

Even if you’re not sure what it is, you undoubtedly know something about glyphosate. Before the world’s attention became completely fixated on COVID-19 and the global quarantine, glyphosate was in the news nearly every day. Why? This common weedkiller has been linked to cancer. More specifically, to non-Hodgkin’s lymphoma (NHL). As CNN reported, one study from last year showed that it increases your risk of NHL by 41%.

Even with the virtual blackout on non-virus-related news, reports about the harms of glyphosate have been rolling in. Here are just a few headlines:

The Grim Truth About Glyphosate
by Jennifer Margulis and Justine Rosenshield

What is glyphosate?

Glyphosate is a man-made chemical, patented as a metal chelator, an antibiotic, an anti-parasite, and an anti-fungal, among other things. Mostly used as a weedkiller today, glyphosate kills weeds very effectively. 

Monsanto is the multi-billion dollar chemical company that brought glyphosate to the market in 1974 under the trade name Roundup. Monsanto’s patent on it ran out in the 2000s. So instead of just being in Roundup, glyphosate is included in hundreds of other weed-killing chemical formulas made by other companies. According to the National Pesticide Information Center, there are over 750 products containing this herbicide.

Where is glyphosate?

Glyphosate is sold in approximately 125 countries around the world. 

It has been banned or restricted in over 20 countries. 

Glyphosate is used both commercially and privately, on and around farms, golf courses, in schools, parks, community areas, railways on pavements and pedestrian areas and domestically around homes, driveways, terraces and in gardens and allotments.  

Commercial farmers use glyphosate to clear fields of weeds before sowing seeds. They also use it on most genetically modified crops. Farmers also apply glyphosate as a drying agent on many non-GMO crops, both in the United Kingdom and the United States. 

Shortly before workers harvest certain crops, like wheat and oats, farmers spray the plants with glyphosate. This pre-harvest practice, called desiccation, helps these crops dry evenly. Farmers believe that it also facilitates and speeds up harvesting. But the fact that glyphosate spraying is done just before harvest means these foods we eat are left with significant glyphosate residue. 

Research has shown that:

• 28 out of 28 popular oat bars tested positive for glyphosate 
• 41 out of 69 honey samples tested positive for glyphosate 
• 10 out of 10 wines tested positive for glyphosate  

The only way to ensure you are avoiding glyphosate in your food is to buy organic. However, you may not be able to avoid it even if the food you eat is 100 percent organic. Unfortunately, even organic food has been found to be contaminated with glyphosate because it’s so prevalent in our water and can also travel through the air. 

How does glyphosate kill weeds?

Glyphosate’s main weed-killing mechanism is said to be due to its ability to interrupt a metabolic pathway called the shikimate pathway. 

The shikimate pathway, say what? If you’re not a microbiologist, you may not have ever heard of this.

This pathway, found in microorganisms and plants, is actually a sequence of seven metabolic steps. Many fungi and bacteria, archaea, algae, protozoa, and plants use the shikimate pathway to create certain aromatic amino acids. Amino acids are the building blocks of proteins. These amino acids include Tryptophan, Phenylalanine, and Tyrosine. Without these amino acids, the organisms die. 

Mechanisms of harm for humans 

So it’s no wonder that glyphosate causes many different problems for humans. “Glyphosate is a profound Zonulin stimulator,” Zach Bush, M.D., explains. Another word you may not be familiar with, Zonulin is an important protein, which helps with intestinal permeability.

If your body makes too much Zonulin you end up with an ongoing leaky gut. Zonulin is produced systemically, opening up protective barrier systems all around the body. Leaky barriers are at the root of many chronic diseases, including general inflammation and autoimmune disorders, Alzheimer’s, chronic kidney disease, heart disease, allergies, and cancer.

Gluten, which is in wheat, rye, barley, oats, and other grains, also stimulates Zonulin production. When you combine gluten with glyphosate you create a perfect storm.

Chances are you know someone who is sensitive to gluten. Maybe that someone is you. It may be that the high levels of people with sensitivity to wheat these days is because of the glyphosate in our wheat, not the wheat itself.

Glyphosate disrupts and destroys crucial elements of our own microbiome. Even at levels deemed by authorities as safe!

Harming beneficial bacteria

Studies show that glyphosate targets beneficial bacteria leaving pathogenic bacteria free to flourish and dominate in our bodies. This is the opposite of what we want: We humans depend on beneficial bacteria to help us regulate our immune systems, digest our food, synthesize vitamins (including biotin, folate,  vitamin K, and B12). 

Beneficial bacteria also help us absorb minerals and play a role in how we store and metabolize food. They make amino acids and neurotransmitters that enhance good mood, energy, alertness, focus, and motivation. Our beneficial bacteria also influence gut motility, blood flow, and the ability to self soothe and calm down after stress. In fact, we are more microbial than we are human. 

The human genome project has been decoding the human genome. We now understand that health is less about the genes we inherit and more about how the inner and outer environment affects which genes are switched on and off. This is called epigenetics. The key players inside our bodies include our non-human genes. We are these creatures. They are us. And anything that damages them damages us. 

9 more harms of glyphosate: a list you don’t want to read

Skim this if you’re feeling overwhelmed. But if you’re a science geek, take a look at the references. Consider printing out these scientific studies and reading them with a yellow highlighter in hand. It’s a depressing, but eye-opening endeavor. 

Glyphosate and glyphosate-based herbicides:

1. disrupt the endocrine system

   even at low levels.
   

2. induce breast cancer cells growth

   via estrogen receptors.

3. cause birth defects and fertility problems, as well as spontaneous abortion

4. affect sperm

   Sperm motility and the motility period are reduced after glyphosate exposure Human sperm counts have more than halved in the last 40 years since Roundup was on the market. There are lots of ways modern life is impacting fertility (most of them from environmental toxins brought to us by corporations, including glyphosate.

5. cause anxiety and depressive-like-behavior

6. disrupt the liver
   

   A rat study showed ultra-low does exposure bringing on fatty liver disease Liver disease is one of the leading causes of premature death in England. One in 3 Americans have it, a study from the University of California, San Diego demonstrates it is dose-dependent.

7. cause oxidative stress

   Oxidative stress happens when the cells cannot keep up with free radical production and is implicated in most chronic diseases. Research has shown glyphosate is a culprit.

8. contribute to antibiotic resistance

   Glyphosate is one of  the most widely used antibiotics on the planet and is dangerously contributing to antibiotic resistance, a very serious problem public health officials are dealing with right now.

9. implicated in generational toxicity

   A study done by researchers at Washington State University study looked at what it termed “generational toxicology,” which is where the physical injury shows up in later generations. In the 3rd generation, greater than 90% of the offspring had at least one or more diseases. Thirty percent of the pregnant females in the 2nd or 3rd generation either died or had offspring that died

Many signs suggest that glyphosate is already devastating human, animal, and botanical health. We have no idea of how much worse it might get, courtesy of this widely used and totally toxic chemical.

Glyphosate disrupts soil microbes

Glyphosate disrupts our microbiomes and it also harms the microbes in the soil too. 

Healthy soil is an alive ecosystem of organic matter, water, air, nutrients,  bacteria, protozoa, fungi, and their metabolites, carbon redox molecules, along with earthworms and other insects, animals, and plants. 

Each member of this ecosystem teeming with life plays a vital role in keeping soil healthy. This abundance of microbial life helps in decomposing and recycling organic matter to break it into elements various life forms can use, distributing soil nutrients, creating structures within the soil so that other life forms can breathe and flourish, and drawing carbon and water back into the soil.  

Without all these life forms, soil is just dust. The nutrients and minerals wash away. Nutrients and organic matter that remain in the soil become unusable to the life forms left. With no life in it, soil loses its structure. Air cannot circulate through it. And life further suffocates. 

Dire implications for the planet

Out of eight studies on earthworms, six showed significant negative impact on the reproduction, movement, and activity of different species of earthworms. 

According to a chilling report in The Guardian, the United Kingdom is just 30 or 40 years away from the fundamental eradication of soil fertility.

Why does healthy soil matter? Because good quality soil and well-managed lands have the ability to sequester large amounts of carbon. 

Healthy soil can hold up to 20 times its weight in water, which in turn benefits microbes, plants, and animals. Mismanaging soil health causes rising temperatures and contributes to the flooding and drought patterns we’re seeing across the planet. 

There are a lot of unanswered questions. But we know that greater length and frequency of glyphosate applications bring more negative effects. Scientists are concerned. We risk further polluting humans, causing crop diseases, hurting earthworms, and compromising soil ecosystems.  If we destroy microbial life we destroy the planet. One of the biggest losers is mycorrhizal fungi. Glyphosate reduces their spore viability and root colonization. 

Mycorrhizal who?

Mycorrhizal fungi are the powerhouses of the soil. They play a vital role in soil structure, breathability, and communication. Unfortunately, they aren’t the only beneficial soil fungi that support plants with nutrients and access to water, particularly in times of drought, that are harmed by glyphosate. 

Without beneficial soil fungi, plants can become too weak to defend themselves against pathogens.  

Scientists now believe that glyphosate has also brought about the re-emergence of crop diseases and increased their severity. 

Glyphosate hurts bees

I wish we finished the gloom and doom. But we haven’t. Glyphosate has also been linked to the dwindling bee populations. 

In one study researchers found that glyphosate killed off the protective gut bacteria in bees, leaving them open to infection by opportunistic pathogens. 

“If insect species losses cannot be halted, this will have catastrophic consequences for both the planet’s ecosystems and for the survival of mankind,” Francisco Sánchez-Bayo, Ph.D., a scientist at the University of Sydney in Australia, told The Guardian.  

Francisco Sánchez-Bayo is an environmental scientist and co-author of a global scientific analysis of what is causing insect population declines. His review insists that the diminishing of insects threatens “catastrophic collapse of nature’s ecosystems.” He points to chemical use as one of the main drivers of insect extinction. And, unfortunately, glyphosate is also present in some organic honey.

A glyphosate-induced global crisis

Sir Robert Watson, Ph.D., is a British chemist and the chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. A champion of the earth and a key force behind reversing ozone depletion in the 1980s, Watson and his team issued the 2018 report, Science and Policy for People and Nature. This report highlights that the crisis we are now facing. As remote as soil bacteria and fungi might seem to our everyday lives, we depend on them. 

All life on Earth deeply connected and interdependent 

“Land degradation, biodiversity loss, and climate change are three different faces of the same central challenge: the increasingly dangerous impact of our choices on the health of our natural environment,” Watson explains.

“We cannot afford to tackle any one of these three threats in isolation–they each deserve the highest policy priority.” We must address them together, he says. 

Land degradation. Loss of biodiversity. Climate change. Glyphosate and glyphosate-based herbicides play into all three of these threats. 

In January 2019 a three-year study commissioned by the Lancet was published. The study, The Global Syndemic of Obesity, Undernutrition and Climate Change, looks at the connection between poor quality soil and poor quality, nutrient-depleted foods. Poor quality foods, in large part courtesy of glyphosate, contribute to poor human health. 

So what can we do about glyphosate poisoning people and the planet?

You probably didn’t need to read this far to realize that glyphosate is poisoning people and the planet.

Even if the big chemical companies that profit from this poison say otherwise, I think we can all agree that this herbicide is bad for humans, bad for microbial life, and bad for planet Earth.

So what can we do about glyphosate?

How do we get rid of it?

We must get glyphosate out of the food chain, water, soil, air, and oceans 

Ultimately this comes down to banning it, which means putting pressure on our governments to do that. 

But industry wields power. A profit-fueled and well-organized industry resists banning glyphosate. 

We also have to make sure that, once we stop the production of glyphosate, farmers don’t swap out glyphosate for equally toxic chemicals. 

The global solution lies in regenerative agriculture

Regenerative agriculture focuses on enriching soil and increasing biodiversity with best practices, not poisons. Regenerative agriculture leads to plants containing more nutrients and soils storing more carbon and water. But conventional farmers who douse their fields in toxic chemicals will need a lot of support to change their practices.

The healthiest food comes from farms with regenerative practices. When more consumers buy organic, more farmers adopt organic farming. If enough people switch to organic, it will become cheaper for everyone. 

Moms Across America is a non-profit working hard to get glyphosate out of the food supply.

The personal solution lies in us

We may not be able to avoid all exposure to glyphosate but we can minimize glyphosate by avoiding wheat products and eating fewer grains, buying only organic food, and spacing out or even indefinitely delaying vaccines (several vaccines have been found to be contaminated with glyphosate, which may explain some of the severe vaccine side effects we are seeing in our kids.) In addition, daily detoxification will also help.

Suggestions on some ways to detox can be found here. We also like this gentle and effective detoxification protocol.

It’s time to dramatically limit our exposure to glyphosate 

Eat real, whole, fresh foods and buy only organic. 

Insist your local grocery stores make organic food affordable for everyone. 

Encourage everyone you know to do the same.
