One of my big caveats to all of my clients is stressing the importance of nutrient dense foods. This is for a number of reasons. For one, nutrient deficiencies drive hunger. This is a survival benefit. Our body will continue to tell us to eat until it has all of the nutrients necessary to complete its daily tasks, which is the other major reason I stress the importance of nutrient dense foods. We need nutrients to help run every system in our bodies. Also, these nutrients give us the firepower to fight oxidative damage and keep us living a healthy life.
Is the modern lifestyle slowly stripping away our abilities to get nutrient dense foods? Genetically modified foods (GMO) take up the majority of the shelf space in our modern supermarkets. Modern farming practices are also stripping the soil of key nutrients as well as adding new chemicals into the mixture. Just as modern foods are new to our body’s ecosystem leading to many different health issues, the same is true for the ecosystems of the foods that we eat.
One of the most common chemicals used is glyphosate. Glyphosate is an herbicide, and in fact it is one of the first herbicides that crops are genetically engineered to resist. This is likely to increase its prevalence in our food products. There is much contradictory evidence out there on whether glyphosate is safe for human consumption or not. This can be expected as big money corporations use glyphosate to increase their crop yields.
You might know glyphosate by another name. Roundup is a popular product that contains this chemical. Studies have been looking at the effects glyphosate has on humans. One side of the argument claims that glyphosate alone may not be harmful to humans, but when combined with other chemicals such as polyoxyethyleneamine (POEA), as seen in products such as Roundup; it can be harmful to humans.
Ingesting greater than 85mL can cause serious health issues including death. Other ailments associated with the ingestion of glyphosate mixtures are respiratory distress, gastrointestinal distress, kidney issues, liver problems, and skin irritation (1). Ingesting this amount of glyphosate is only seen in cases where it was intentional.
Monsanto argues that glyphosate is harmless to humans because we do not contain the shikimate pathway. The shikimate pathway is a metabolic pathway used by bacteria, fungi, algae, and parasites. We may not contain this metabolic pathway directly, but our gut bacteria do. We have more bacteria in our bodies than we do human cells. This may be the case of big companies twisting science around to keep maximizing profits at any cost.
There are a lot of interesting health trends that began to occur at the same time we began to use herbicides such as glyphosate. Autism rates have been one major health concern that continues to get worse with the increase in glyphosate usage. This is just a correlation and does not show causation. This correlation warrants further investigation to glyphosate’s potential role in the increase in autism that we are seeing.
Stephanie Seneff, a researcher at MIT, has been doing a lot of fascinating research on this topic. In one of her presentations she showed if the current trend in the rise in autism continues, by 2032 50% of the children in the United States will be diagnosed with autism (2). She also shows correlation between glyphosate usage and breast cancer.
Current research has shown that glyphosate negatively affects our gut microbiome by suppressing our p450 enzymes (3). This research is showing that the negative effects of glyphosate are not to our human cells, but to our gut bacteria. Our p450 enzymes are responsible for protecting us from foreign materials that enter the system. This leaves us susceptible to damage from environmental toxins. This research suggests that this decrease in p450 enzymes and increased vulnerability to environmental toxins can lead to Alzheimer’s, cancer, autism, heart disease, depression, obesity, diabetes, and other diseases of Western society.
Impairment in p450 enzymes is hypothesized to be an issue in patients with Celiac’s Disease (CD). This is due to the increased usage of glyphosate in wheat products as well as some of the other similar characteristics that CD patients share with inhibited p450 production. This includes deficiencies in vitamin D, iron, cobalt, copper, and manganese, as well as deficiencies in tyrosine, methionine, and selenomethionine (4). Again, this is nothing more than mere correlation, but an interesting correlation none of the less.
This is not the only hypothesized issue with glyphosate. There is conflicting research out there on whether glyphosate resistant plants contain mineral deficiencies. These are GMO crops that are engineered to resist the damage that could otherwise be caused by the herbicide. Glyphosate can then bind to nutrients and decrease their availability.
Also, when glyphosate binds to minerals and is consumed by animals, it will pass through the digestive tract undigested and be redistributed through the feces of that animal. This is one way that GMO plants and glyphosate can be redistributed to clean soil. These mineral deficiencies can also make the animals sick much like we can see in humans. This leaves us with a nutrient deficient food supply.
Our guts are not the only thing that has a microbiome. Our soil also has a microbiome. Herbicides and fungicides, and other chemical products used to protect plants alter this microbiome. This alters the available minerals and nutrients that the soil will pass along to the crops since certain strains of bacteria and fungi are responsible for giving the crops their nutrient content. This may be one explanation to the rise in nutrient deficiencies that we are seeing.
Current research is looking at how to manipulate the soil to best increase plant health and the nutrient density of foods (5). It looks as if the soils surrounding the roots and the roots themselves have this two way street of nutrient exchange that current farming practices may be altering in a negative manner.
We need to make changes to our current farming practices to before we go too far and cannot go back. Modern herbicides and fungicides are destroying the microbiome of our soil and decreasing the available nutrients in our food supply. There are also interesting correlations between diseases of Western society and the widespread use of the herbicide, glyphosate. There is no risk from avoiding glyphosate by eating only non-GMO foods, but may be a great reward in the end.
Try to buy local organic produce and meats when you can. It is always a good idea to visit the farm and look into the farming practices yourself to make sure you are getting what you think you are getting. In the end your long term health may thank you.

re: There is no risk from avoiding glyphosate by eating only non-GMO foods, but may be a great reward in the end.
True, but people need to know that glyphosate uptake can easily be present in non-GMO crops, and I’m not speaking of pre-planting residues.
It is routinely used on mature grain crops for “dessication”, a euphemism for terminating growth in the crop for more convenient harvest timing. Glyphosate obviously gets into the crop, because it kills it.
The #1 non-GMO crop that is dessicated is wheat, which readers of this blog probably avoid already.
Seneff has argued that dessication may explain some of the ailment trends, but I don’t think the practice has been used long enough to support that conjecture.
Sage says
In reply to Boundless…. the use of glyphosate as a “burndown” applied to a field a few days before seeding the crop, has been done since the early 1990s at least, with many crops. Lentils are one crop that i know for certain had this done. And, pre-harvest application of glyphosate is also done on lentils and on wheat and on sugarcane and many other crops. It’s not uniformly done but it’s very common. Oats, as well. Some glyphosate is bound to reach the food product when this is done, as well as with the burndown pre-planting application, since glyphosate *does* uptake through roots, incontrovertibly.
Janknitz says
I have read Seneff’s claims that desiccation is a common practice for grain harvest but I’ve yet to see her claims corroborated. I’m curious if her claims are true. I don’t eat grains, and her claims would explain a lot, but where’s the evidence?
Something that is rarely discussed is the farm worker’s exposure to glyphosates. Studies on farm workers and their children in the Salinas Valley evidence the dangers of exposure. We owe a duty to the people whose hard labor puts food on our tables not to poison them and their children in the process.

re: … claims that desiccation is a common practice …
I first heard of it 3 years ago on Davis’ Wheat Belly Blog:

Sage says
The main issue i have with glyphosate being present in most of our foods — in wheat, soybeans, corn, corn syrup, sugar, lentils, garbanzos, sugar beets, oats and so much else — is that it appears very likely that glyphosate affects the human gut microbiome in ways that are harmful to human health. Not deadly but harmful and perhaps causing further complications and making disease more likely. This has NEVER been tested by any feeding study ever done. When someone claims that glyphosate has been “proven” to be safe by multiple feeding studies, ask them if there is any feeding study at all that actually checked for effects on gut microbiome population disturbances. I think they would be hard pressed to find that study as it’s never been done. Therefore, one cannot in good faith and full knowledge, say that glyphosate has been shown to be safe for human consumption. And yet, it’s in our foods, and most people get 100 micrograms per day of this very potent chemical that blocks a key metabolic pathway in the beneficial microbes in our gut. How is that ok?
Ron says
Seneff is an utter quack. The fact that she’s an “MIT researcher” is a pathetic appeal to authority. She has degrees in engineering and computer science. None of her study or work qualifies her to speak on epidemiology, toxicology, developmental delays, etc.
Her fun correlations don’t explain causation as she provides no mechanism for her ridiculous claims.
Robb Wolf says
Ron-
Not sure if it’s this piece but a proposed mechanism HAS been put forward. I’m still on the fence with all this, but the “appeal to authority” gig cuts both ways.

You know, I love that the web allows for so much knowledge to be transmitted. However, it also allows for fraudulent information, speculative “truths” and propaganda (usually sales related) as well as false socio-political information to be disseminated.
In the future please provide all your reference studies so that one can assess the factual information by reference.
Thank you
