The Harmful Effects Of Weedkiller (Glyphosate) On Our Health And Our Future with Stephanie Seneff

Coming up on this episode of the Doctor's Pharmacy.

It's out there. You can't avoid it, unfortunately, and we're all getting sick as a consequence of it. I think it's the major driver behind the rise in the huge list of diseases in this country, you know, diabetes, obesity, autism, Alzheimer's, various cancers. It's quite shocking. These things are all rising dramatically in prevalence over time, exactly in step with.

The rise in glyphosate usage on corn crops. Hey everyone, it's Dr. Mark. I know a lot of you out.

There are practitioners like me, helping patients heal using real food and functional medicine as your framework for getting to the root cause.

What's critical to understanding what each individual.

Person and body needs is testing, which is why I'm excited to tell you about Rupa Health. Looking at hormones, organic acids, nutrient levels, inflammatory factors, gut bacteria, and so many other internal variables can help us find the most effective path to optimize health and reverse disease. But up till now, that meant you are usually ordering tests for one patient from multiple labs.

And I'm sure many of you can.

Relate how time consuming this process was and then it could all feel like.

A lot of work to keep track of. Now there's Rupa Health, a place for.

Functional medicine practitioners to access more than 2000 specialty labs from over 20 labs like Dutch, vibrant America, Genova, Great Plains and more. Rupa Health helped provide a significantly better patient experience and it's 90% faster. letting you simplify the entire process of getting the functional medicine lab tests you need and giving you more time to focus on patients. This is really a much needed option in functional medicine space and I'm so excited about it. It means better service for you and your patients. You can check it out and look at a free live demo with a Q&A or create an account at RupaHealth.com that's R-U-P-A-Health.com Now supplements are one of those things that I'm always being asked about. Is it worth spending money on them? Do we need them if we really eat well? Can your body even absorb them? The answer to the most of these questions is, it depends. There are definitely certain supplements I'd never recommend taking because they aren't made in a way that your body can take advantage of and you just pee them out. And there are definitely some supplements we can benefit from because our food supply, even if we're eating whole organic foods, because that doesn't just provide enough of the nutrients that we need for optimal health. A major one of those nutrients that I suggest people supplement with is magnesium. Most soils have become depleted of magnesium, or there's not organic matter enough to draw the magnesium out of the mineral rich soil into the plants. So it's a tough mineral to get enough of through the diet. 80% of Americans are actually deficient or insufficient in it. And since it's crucial for hundreds of reactions and enzymes in the body and impacts everything from metabolism to sleep to neurological health, energy, pain, muscle function and more, it's really important we strive to get enough of it. Magnesium also plays a role in our stress response and everyone I know could use a hand in better managing stress to promote better overall health. I like to call magnesium the relaxation mineral. My favorite new magnesium is from a company called Bio-Optimizers. Their magnesium breakthrough formula contains seven different forms which all have different functions in the body. There's truly nothing like it on the market. I really noticed a difference when I started taking it. I've tried a lot of different magnesium products out there. I also love all their products and how they're gluten free, soy free, lactose free, non-GMO free of chemicals fillers and made with all whole real natural ingredients. Plus, they give back to their community. For every 10 bottles sold, they donate one to someone in need. Now, that's pretty awesome. Right now, Bio-Optimizers is offering my listeners 10% off your order. Just go to magbreakthrough.com/hyman. That's M-A-G-Breakthrough B-R-E-A-K-T-H-R-O-U-G-H.com/hyman and use the code HYMAN10 to receive this amazing offer.

I think you'll love it as much as I do.

Now let's get back to this week's episode of the Doctor's Pharmacy.

Hey everybody, it's Dr. Mark Hyman. Welcome to the Doctor's Pharmacy. That's Pharmasooth and F-A-R-M-A-C-Y, a place for conversations that matter. And if you care about your health and the environment, if you care to learn about glyphosate, otherwise known as Roundup or the weed killer that's causing havoc to our health, planetary health, our microbiome, the microbiome of the soil, and many, many other issues, then you should listen up carefully because we have an extraordinary guest today, Stephanie Cenat, who is a senior research scientist at MIT, Massachusetts Institute of Technology. She's at the Computer Science and Artificial Intelligence Lab. She has a bachelor's degree from MIT in biology with a minor in food and nutrition science, a master's degree in engineering degree and a PhD degree, all from MIT. You stayed true to MIT. And also a degree in electrical engineering and computer science. So this is one smart lady and her really, Focus these last years has been on the role of toxic chemicals and micronutrient deficiencies in health and disease. And I followed her work. I'm a big fan of hers. She really focuses now on this herbicide glyphosate, otherwise known as Roundup. It's a weed killer, and it is the most prevalent agrochemical used. It's on 70 of all crops. And she also is looking on how these affect different minerals and sulfur and other things. She's authored over three dozen peer reviewed papers on these topics. She's for an incredible new book, which you all have to get called Toxic Legacy: How the Weed Killer Glyphosate is Destroying Our Health and the Environment. And it's out, so make sure you pick up a copy. This is a game-changing book. And some people have compared this book to Silent Spring by Rachel Carson to really reveal the underbelly of what these chemicals are doing to human and planetary health. And the more I learn about it, the more scared I get about it. And I don't think we're out of the woods, even if it's banned, because there's other chemicals that are being Now developed by major agrochemical companies to replace it as kind of better than, but often that isn't really the case. So welcome, Stephanie, to the Doctors Pharmacy Podcast.

Thank you for that wonderful introduction.

Okay, so now let's get right into it. Glyphosate is this active ingredient in Roundup. It's the most commonly used weed killer in the world. There's about 300 million pounds of this herbicide sprayed on farms and food every year. Is that just in the United States or that globally?

I think it's probably more globally. Yeah, 9 billion globally, I think.

9 billion. 9 billion.

Kilograms. Kilograms.

Sorry. You always have to watch the units. 9 billion. That's an incredible amount. I don't even know what 9 billion kilograms looks like, but it's mind-bogglingly big. It's on 70% of all crops and it's been around for a while, but not that long, right? In the 70s, it started being used and was actually used to sort of clean pipes. I was supposed to clean all leaded pipes and stuff and all the gunk out of water pipes, but it turned out as it came out of the other end, it started killing all the Weeds. And they're like, oh, there's a weed killer. So talk about the history of glyphosate, why farmers use so much of it, and why it's so toxic and bad for us.

Yes, well, it was, you're right. 1961, it was patented as a pipe cleaner, and it wasn't Monsanto, but Monsanto figured out it could kill weeds, and they patented it in 1969 for that specific role. And then '74 was when it got rolled out in America. We started being able to buy it. and they didn't use that much up until the late 1990s, which was when they figured out how to engineer crops to resist it. That was a huge breakthrough in agriculture. That caused a huge increase in the use of glyphosate, exponential growth over time in those next decades. Since then, really, it's just been growing phenomenally because it's been successful in just spray the weed killer all over the crop. The crop doesn't die, the weeds die. It's very convenient for agriculture and it's made our food cheap. United States uses 20%. of the world supply and we're only 4% of the world population. So you can see that we get a lot more exposure than people elsewhere in the world. We have the most per person of any country in the world.

That's terrifying. I've actually checked my urine glyphosate levels and I'm like, I pretty much focus on eating organic food. I don't try to eat any GMO foods. I mean, I'm not perfect because if I go out to a restaurant, I don't know what I'm getting. And I was shocked that I was in the 50th percentile for glyphosate in my body.

It's really disturbing, isn't it? I had a similar experience. I was shocked that I had any at all, and I tested, I was positive. And I eat organic. I eat certified organic for many years. So it's just, you know, it's out there. You can't avoid it, unfortunately. And we're all getting sick as a consequence of it. I think it's the major driver behind the rise in the huge list of diseases in this country, you know, diabetes, obesity, autism, Alzheimer's, various cancers. It's quite shocking. These things are all rising dramatically in.

Prevalence over time, exactly, in step with the rise in glyphosate.

Usage on core crops.

Yeah, it was interesting. Rachel Carson wrote Silent Spring. She talked a lot about the birth defects and also the sort of developmental effects of these chemicals, which got people to really think about them. But the glyphosate is a little different. It doesn't seem to cause developmental effects, but it causes all these other issues like cancer and destroys our microbiome. So can you talk about what it actually does to the human body, but also the soil? Because I think it's very similar in its adverse effects around harm the microbiome of the soil and harming our microbiome, which turns out to be a very important part of our biology and may link all those diseases you mentioned.

That is so true. And that's what I've realized is that, and of course others have too, because the number of papers on the microbiome is going up very rapidly in the last 10, 20 years. People are finding how important those microbes are because they're not working correctly. People are getting so many diseases that trace back to mitochondrial to the microbiome disruption. And glyphosate, unfortunately, preferentially kills the beneficial bacteria. That's crucial. It kills off Lactobacillus and Bifidobacteria, which are really important in the baby to really get started with drinking milk. Lactobacillus is very important because it has a lot of enzymes that specialize in breaking down casein in milk, the milk protein. And so when those enzymes are missing, the baby can't digest milk. And that has lots and lots of consequences. We get things like casein intolerance, gluten intolerance. I think it's due to this lactobacillus being disturbed by glyphosate and disrupting their ability to help us digest these foods that we're eating. Then of course, these pathogens take hold because the beneficial bacteria are weak and depleted. Then the pathogens induce a leaky gut, inflammatory gut, the immune cells come in and things go south from there. People just have a lot of problems with their gut. I have a whole chapter on the gut in my book and that was a really hard chapter to write. I had to read a lot of to kind of coalesce into a story. But I finally got what I was happy with as a story for all the different things that GliF is A does, much more than what I've just said now, of course, related in part to the inability to break down proteins. And that becomes very serious because it can end up with autoimmune disease when those proteins that you eat are not broken down in your gut. Then that induces a leaky gut. And then that also allows those proteins to get out into the general circulation, which then causes antibodies to those proteins. antigens. And then through a process called molecular mimicry, they become autoantibodies and attack your tissues. So you get autoimmune disease.

Yeah, what you just unpacked there was so important. I just want to underscore it because when you are exposed to glyphosate, it seems to directly impact the microbiome by killing off your inner garden in ways that prevent it from actually protecting you the way it's supposed to from disease. And the glyphosate seems to be responsible for to increasing this widespread phenomena of leaky gut, which means that the barrier in the gut is broken somehow, and the proteins and the toxins from the bacteria and also food proteins leak, literally leak into your bloodstream, interact with your immune system and create a systemic response of inflammation. And all the diseases that you mentioned, cancer, liver disease, autism, you know, heart disease, diabetes, I mean, these are all inflammatory diseases. So, so take us down that road a little bit more. in depth about how glyphosate, despite it being claimed as safe by the food companies for humans, animals, and the environment, why it's not safe and how specifically the evidence is mounting around how it's connected to these various diseases. And we see that even in courts, and while this may not be played out in regulatory changes, it's being played out in the courts where 14,000 lawsuits have been filed against glyphosate, and there's been billions in settlements against the Monsanto bear now, which actually owns Monsanto. So can you talk more about the science of how much do we know, how well is this proven, is this just hearsay, or is there good data linking glyphosate with these problems?

Yes. Well, when you start with the gut microbes, and of course glyphosate is a metal chelator, that was the first way that it was patented. And when it binds to minerals, it makes them unavailable to the gut microbes. That's part of the impact of how it disrupts them. It hits on a particular enzyme called EPSB synthase in the shikimate pathway. And that's a very, very important biological pathway in plants. And it's also very common in the microbes in our gut. Something like a study showed 54% of the gut microbes would be affected by this specific problem of the shikimate pathway getting disrupted. That pathway produces the aromatic amino acids. And those are three of the coding amino acids that go into the proteins. We depend upon getting them from our food or from our microbe production of them because our cells don't have that shikimate pathway, they can't make those proteins. They can become deficient and those proteins, those amino acids are really critical. The aromatics, this tryptophan, tyrosine, and phenylalanine, they're super critical for our health. For example, tryptophan is a precursor to serotonin and melatonin. Those are neurotransmitters that are extremely important for proper brain function. Melatonin sleep disorder is going up dramatically in step with a rise in glyphosate because probably in part because of disruption of melatonin supply. And serotonin is the mood hormone, you know, it's related to depression, violent behavior, it's deficiency. And they come out of that shikimate pathway. Also thyroid hormone, it comes out of the shikimate pathway as well, a different amino acid, tyrosine rather than tryptophan. And so thyroid hormone is going to be disrupted. Many studies have shown that glyphosate disrupts thyroid homeostasis. So the hormones are getting disrupted, the amino acids are being depleted. Also, those enzymes go to B vitamins, niacin and riboflavin. Niacin and riboflavin are precursors to molecules called NAD and FAD, which are very, very important for metabolism. And their deficiency is going to disrupt the mitochondria. And I think mitochondria- and you can't make energy. Right, you can't make energy. Mitochondrial dysfunction is central to so many diseases. And I think it's also central to glyphosate's effects. on the body. If I had to say one thing, I would say mitochondrial dysfunction as a key feature of what glyphosate does. And many papers have shown that it causes oxidative stress, it causes depletion of glutathione, it causes glutathione to be oxidized, which is important because glutathione is a.

Really important antioxidant only if it's reduced. Wow. So that's just a lot you unpacked there. Let me see if I got this right. If you're exposed to glyphosate, it harmfully affects the bacteria in your gut that produce really important amino acids that regulate your gene expression. And the pathway it disrupts is a shikimate pathway, and that leads to abnormal gene expression and not being able to actually do the things your body's supposed to do.

And.

It also seems to deplete glutathione, which you mentioned, which is a critical molecule for regulating inflammation, detoxifying antioxidant. It's really the center of our biology. and if it disrupts that, we're kind of screwed.

Right, glutathione is so important. And we're seeing so many people talking about, you know, taking glutathione as a supplement, taking anacetyl cysteine to as a precursor to glutathione. Methionine is the core essential sulfur-containing amino acid, and it is a precursor to cysteine, which goes to glutathione. Methionine synthesis is disrupted by any E. coli, by glyphosate. There was a study that showed that. So it prevents the microbes and also prevents the plants from producing methionine from inorganic sulfur. So this gives you again a deficiency in the sulfur containing amino acids. So we have a deficiency both in the aromatics and in the sulfur containing amino acids. And they're so important for so many things. It's just uncountable practically the ways that that would impact, particularly your metabolism, of course also protein synthesis and of course all the hormones that are affected. And the B vitamins, all of those things are going to be affected by these disruptions by glyphosate.

And, I mean, you're an MIT scientist. This is not some crazy fringe idea. You're an evidence-based scientist. It's looking at the data and coming to these conclusions. Well, first before we get into why the government hasn't figured this out yet, let's talk about other diseases and how good the evidence is. How good is the evidence around cancer, for example? or diabetes or autism or any of these autoimmune issues that you're talking about.

Yeah, cancer is actually the hardest one to explain. And maybe the weakest one, in fact, I would say cancer, of course, evolves out of mitochondrial dysfunction, so eventually it causes it. Studies have shown that it enhances other chemicals effects that would lead to cancer. In other words, it's a secondary effect. There are studies that have shown that. And there are also studies that have shown that it causes cancer cells, breast cancer cells in vitro proliferate when they're exposed to extremely tiny levels in parts per trillion, parts per trillion levels of glyphosate induced proliferation in cancer cells. I think it does cause several different cancers, but it's a much more difficult thing to explain than some of the other diseases. Liver disease is quite easy to explain. If you accept my theory, which we maybe should get into at this point because that's crucial, my theory for its extremely unusual mechanism of toxicity, so, and.

Just to back up for people, a liver is your detoxifying organ. And, and you hinted at how glyphosate interrupts sulfur metabolism, which is a critical part of our biology. And in functional medicine, you know, there's, there's a real focus on our sulfur biology because it's critical for detoxifying all the environmental compounds are exposed to, for metabolizing our own internal toxins and, and people who have low glutathione, which is the sulfur based compound are sicker. I remember reading one study that if you looked at people who are hospitalized versus not hospitalized, if you have this general lower levels of glutathione based on a gene that is important in regulating it, 50% of the time you're going to be more likely than up in the hospital. So it's kind of a marker for overall health and well-being. And I personally have a lot of experience with glutathione because I had mercury poisoning and it gets very depleted. And I had to learn how to restore my sulfur metabolism and also something called methylation, which is the B vitamins, because they're very interlocked. And when you think of your biochemistry, for those listening, it's like this big network of biochemical reactions, but right at the center of it is these two core systems that run all the time, literally every second, millions and millions of times a second, billions of times probably called methylation and sulfation. And these pathways, I've written a lot about them in books and articles, but this is the key to health. It's the key to gene expression, to immune function, to detoxification. to cognitive function. I mean, it just goes on and on and on. So when this is screwed up, it's not just like some, you know, sort of minor pathway that gets disrupted in human biology. It's a major pathway. So with that background, can you explain how glyphosate disrupts sulfur metabolism a little more clearly and, and, and explain, you know, what really the role of, of the sulfurs in maintaining health and why we should be terrified about glyphosate and sulfate. Right.

I think glyphosate disrupts sulfate synthesis, sulfate activation, sulfate transport, and sulfate delivery. It disrupts every step of the way for sulfate. And as you mentioned, mercury actually gets sulfated to detox it. If you can't sulfate the mercury, you're in trouble. I think that we have a systemic deficiency in sulfate in the glycocalyx, which is this lining of all the cells, like in the blood vessels. There's all this sulfate that populates the sugar molecules, complex sugar molecules in the lining of the blood vessels. Those need to be heavily sulfated to have the blood circulation work correctly and also for the cells to be able to receive signals and to bring in different things they're going to take in to digest. It's just really Central, having enough sulfate in them around the exterior of the cell. It also gives the red blood cells negative charge, which is important for the Zeta potential in the blood. There's all these things that are connected to sulfate. And I talk a lot about sulfate in my book. It's actually been central to my understanding of where biology has gone wrong. And I felt sulfate was in trouble with autism and with heart disease many years ago, long before I knew about glyphosate. So the sulfate and the glyphosate really came together very nicely for me, for me to recognize how glyphosate is causing autism and probably heart disease through sulfate issues. And as you mentioned, the sulfation, sulfation is very important for detoxing many of these fat soluble chemicals. that they go to the liver, it takes them, it's the liver's job to detox them and it takes them up, it adds sulfate, oxidizes them, it adds sulfate. The enzymes that, the SIF enzymes that take, that do that first step of detox are also suppressed by glyphosate. That's been shown in multiple studies. It suppresses the enzymes in the liver that modify these fat-soluble molecules to make them, to detox them and to make.

Them water-soluble so they can be removed through the urine. they also- Wait, wait, wait, wait, wait, wait. So, so what you're saying basically is when toxins come in the liver, they have to be detoxified by the liver. And there are enzymes that do that that are like the helpers. What you're saying is that glyphosate screws up those enzymes so those chemicals can't.

Get processed down the assembly line of detoxification. Yes, and of course then those chemicals become much more toxic. So glyphosate makes many, many other chemicals much more toxic than they would otherwise be because it disrupts the liver's ability to detoxify them. And of course, glutathione is part of that problem because a lot of things get glutathione, glutathione, to get removed as well. There's methylation, glutathionylation, sulfation. These are all steps that are taking the liver to make these, to change these molecules into something that's less toxic. And that process gets broken down by glyphosate. So it's really quite remarkable, all the things that it can do to disrupt your health. The sulfate, the whole sulfate story in part, it's because these chicken mate pathway, because the chicken mate pathway produces those aromatics. For example, serotonin gets produced in large amounts in the gut, actually, and also melatonin. They both are producing large amounts in the gut. They are sulfated before they're shipped out, and then they arrive in the brain in a sulfated form. So I think the serotonin is actually transporting sulfate to the brain. This is something I talk a lot about. There's all these molecules that get sulfated in transit, not just the toxic chemicals, vitamin D, cholesterol, various sex hormones, they're all sulfated when they're shipped out. Then all these aromatics that come out of the shikimate pathway. Those molecules become deficient, which means that the sulfate transporters become deficient, which means that the brain doesn't get enough sulfate. Autism is very strongly linked to heparin sulfate deficiency in the brain ventricles. That's really been a core feature of autism that's been shown in both mice and humans. I think it's just because there's not enough sulfate being delivered. to the brain. And the body does something very interesting to get around that, which is quite fascinating and also quite disturbing, which is that it produces hydrogen sulfide gas in the liver, in the gut. The autistic children produce hydrogen sulfide gas, which then floats up to the brain and then gets oxidized in the brain to make sulfate. So it's a way to transport sulfate, a very sneaky way to transport sulfate, by turning it into a gas, turning.

The sulfur molecule into a gas, hydrogen sulfate.

It also makes the kids poop's really smelly and stinky. Yes, and it also gives them brain fog because hibernation is all involved with hydrogen sulfide gas. And it's basically people go into hibernation because they've got hydrogen sulfide floating in their brain. Their brain is, and then of course you have to have oxidizing agents to oxidize it to sulfate, which gives you the inflammations, the inflammatory process in the brain that's characteristic of autism. This kind of, you know, chronic low-grade encephalopathy that's a feature of autism is.

Because the autistic brain is constantly trying to make sulfate from hydrogen sulfide gas. Okay, wow. This is just so much information. I'm just loving this. I think just unpack it a little bit for people. You know, when you eat foods with glyphosate, which is 75% of all or 70% of all crops, and often it's used on GMO foods like soy, but even non-GMO foods is used on like wheat. It is a whole host of different ways in the body that it screws things up, right? So what you're saying, it screws up this pathway that makes the neurotransmitters that help regulate gene expression important for cognitive function. It disrupts glutathione, which is critical for detoxing mucification, regulates immunity and oxidative stress. It also affects protein synthesis and immune function and can create a leaky gut, destroy the microbiome. So you've got all these mechanisms, not just one, but many mechanisms by which glyphosate destroys human health.

Right. Yeah. And people say, how can one chemical cause so many diseases? I showed all those charts. Nancy Swanson was the first one who started doing those charts. I don't know if you saw those of rise into various diseases strongly, absolutely. practically perfectly correlated with the rise in glyphosate usage on corn crops over time. It was just stunning. And p-values are 0.00000, I mean several zeros before the first significant digit of the correlations between these two trends in disease versus the rise in glyphosate usage. And, you know, people would say, well, they would say correlation doesn't necessarily mean causation. Then they would say, how could one chemical cause so many diseases? And I was wondering that myself, but now I understand how, and it this metal, it disrupts the whole minerals are completely messed up. The iron, manganese, zinc, they become both toxic and deficient at the same time because of its ability to bind to them and hold on to them, prevent the natural system from transporting them properly. And then it's the sugar mate pathway getting wrecked, and that's all these aromatic amino acids and all the derivatives that are so important for our health are getting reduced. And then, and then it's actually the sipe enzymes in the liver. These are all, have all been shown, you know, in multiple studies that it's doing this, the sipe enzyme in the liver getting suppressed, which is cytochrome P450 enzymes, which is stage one detoxification depressed. And then this inability for the gut microbes to convert inorganic sulfur into organic sulfur, which is going to give you methionine. And methionine, of course, is the methylation pathways. It's the sulfation pathways. Those are all going to be disturbed because of deficiency in methionine.

And instead, the sulfur gets reduced to hydrogen sulfide gas, which then causes all these other problems. So it just jams up your biochemistry. It's just like throwing a sand in an engine, basically.

Right, right, yes.

Amazing. Hey everyone, it's Dr. Mark. Most people don't realize that our exposure.

To light has a huge impact on our health. And that's because we're wired to respond to the changing position of the sun, which regulates our body's circadian rhythm and either helps us to feel energized and awake or lets us know it's time for bed.

Bet.

But our modern always-on culture means we're now surrounded by conventional LEDs and fluorescent bulbs and digital devices with bright lit screens that emit junk light around the clock. My friend Dave Asprey actually coined that phrase, junk light, to describe the excess of blue light as well as green and violet light that disrupt our circadian rhythms. Junk light reduces our ability to produce melatonin, which is a key hormone for regulating our internal clock, sleeping well, and even aging well. It's important to realize we actually need to be exposed to certain amounts of blue light in the daytime otherwise we may feel too sleepy or tired. It's the excess of all that blue light along with other types that leads to a long list of potential problems. So how can we get just the right amount of light throughout the day? Well, going outside is of course key.

But we almost all work on computers.

These days and have our phones with us 24/7. And that's why I was really excited to learn about the True Dark Daylight Glasses. True Dark Daylights are meant to be worn during the day. They come with either clear lenses that block 40% of blue light or yellow lenses that block 75% of blue light. Some of these daylights also act as transition sunglasses that in addition to blocking toxic blue light indoors also have photochromatic lenses that are darker when exposed to natural sunlight outdoors and block 99% of UVA/UVB rays. So they double as sunglasses. With True Dark Daylights you help prevent eye strain and headaches from overexposure to junk light but you stay awake and alert TrueDark also has a Twilights connection for nighttime to help you get deeper sleep. These glasses use red lenses to block the full junk light spectrum, including blue, green, and violet light. Right now, you can get 15% off at truedark.com/hyman with the code DRHYMAN15. That's truedark.com/hyman with the code DRHYMAN15. Now let's get back to this week's episode of the Doctor's Farmacy.

And a few other things I want to sort of touch on, which is glycine. Glycine is important amino acids. I know you're going to say that. And it does affect our protein synthesis and tell us how our body has swapped out glyphosate for glycine and what that does.

Yes, and that's a central topic of my book. That's almost the point of my book is to try to convince the audience that that's true because I've gotten, I've been saying this, Anthony Samsa was the first one who suggested to me that might be happening, that it's substituting for glycine during protein synthesis. And at first I was skeptical because it has an extra piece attached to its nitrogen. It is a complete glycine molecule and it does disrupt glycine in various ways that's known. But it also potentially could be substituting for glycine during protein synthesis. And there's no reason to stop it, it turns out, because proline is a coding amino acid that also has an attachment to its nitrogen and it's still able to find. There's another linkage that the nitrogen can hook up with the other because the amino acids have to hook up in a chain, and the nitrogen is involved in the hook. They're like paper dolls holding hands, and the nitrogen needs to hold hands. It has something in the way, another molecule in the way, but if there's enough room around, it can fit. So it turns out there are specific circumstances under which it will substitute. And this gets a little complicated in terms of the science, but it's quite, quite interesting because the enzyme in the shikimate pathway that gets disrupted by glyphosate has a glycine residue. at the site where it binds the phosphate piece of phosphoenolpyruvate. So that enzyme binds that molecule at a place where glycine is highly conserved. And if you take that glycine out and replace it with alanine, which is just an extra methyl, a very small change, glyphosate can't affect it at all. All of a sudden, it's completely immune to glyphosate. Once you remove that glycine, and they've shown that it is at that place where that glycine is that it disrupts the protease. They've shown that that's the spot, and they know that if they can either remove that glycine or they can crowd it, they can put in other amino acids close by that'll crowd the glycine and then the glyphosate won't fit anymore. So the argument they say is that glyphosate is replacing the substrate PEP. What I say is that it's replacing the glycine. So we have a very different view of how that enzyme is getting disrupted. If you say it's displacing the glycine, and if you say it can displace the glycine and other enzymes that have the same property. And there are many, many enzymes with very important functions that have glycine at a place that's highly conserved that binds phosphate, even that binds PEP, the same substrate. And I suspect it's affecting many of those enzymes. It's that particular group of enzymes that are getting extremely disturbed by glyphosate and that have enormous roles in metabolism. And that's how you're going to get.

Mitochondrial dysfunction, all kinds of so it screws up your immune system, it screws up your mitochondrial energy, it screws up your gut, creates oxidative stress, it screws.

Up your detox system. What doesn't it do? I know, that's the big question. Cancer is an interesting one, and there are cancers that are going up dramatically. Pancreatic cancer, thyroid cancer, liver cancer, and kidney cancer. It definitely affects a lot of the endocrine system, basically. The glands, that's what I want.

Yeah, huge. So there's 9 billion kilograms of this stuff sprayed around the world, 300 million pounds or kilograms done in the United States, is a lot. We're exposed to this in significant quantities, right? And so what is the amount that is going to cause harm? Oh, I know. That's the real question, right?

I think it needs zero. I think we need to ban it worldwide and we need to work hard on figuring out how to get it out of the soil. out of the air and out of the water. We have a huge problem right now. We've got all kinds of glyphosate gathering up because it takes it a long time to... well, it can get broken down quickly under optimal conditions. And of course Monsanto says that that's what's always there. Two weeks later it's gone. That's what they say. It is definitely not true experimentally in many different kinds of soils. It'll last for years. There was a study that showed that after two years, 60% of it was still there. there. So it, you know, and it stays in the ocean. If it gets deep and there's no sunlight, sunlight helps to break it down. There are certain microbes that can metabolize it, but most microbes can't. So it has to be specialized microbes. I think we need to do research to actually figure out which microbes can we safely put in the soil to help break it down, because actually many of the pathogens can break it down, like the fungus. We have all kinds of problems with fungus infections. in both animals and plants and fungus can break it down. So I think that's a reason why it's thriving.

Incredible. So the amount we need is not very much, right? If you were going to look at the data, is there any data on how much glyphosate is in people? And if you look at the population, have they studied like, what is the body burden of glyphosate and is it in amounts that are really relevant or not?

Yeah, that's a big question. Of course, it's a question of what you think is relevant. And one thing, it has been found in people, it's been found in large amounts, and in fact, it's been found correlated with disease. There was a study that showed people who had liver, fatty liver disease, which is an epidemic, and the people who had fatty liver disease, they were tested for glyphosate in the urine, and they had statistically more than the ones who didn't have the disease. And among the ones who had it, the ones that had worse disease had statistically significantly more than the ones who had less worse disease.

Wow.

That's just fatty liver.

And there was a study- It's 90 million, by the way, 90 million people.

In America are affected by that. Yeah, it's huge. And I think life states really dead on. And a study on rats exposed them to levels of glyphosate that were below regulatory limits and caused fatty liver disease in those rats at those levels. The other thing that's coming out at least lately, which is really shocking, is extremely low levels of glyphosate causing endocrine effects that are long lasting. There are these amazing experiments coming out recently where people expose pregnant rats to glyphosate at levels that are so low the rat doesn't look like it has any problems. The rat is perfectly fine. The babies are born. Everything's good. The pups grow up. They have their own offspring. They grow up and you see all kinds of problems.

So in other words, it's showing up in the second and third generation. So in the grandchildren of the rats that got exposed, there's the epigenetic changes that are passed through the lineage to other generations. So you're not only dealing with what.

You'Re exposed to, you're dealing with what your grandmother was exposed closed to.

Yes.

And of course, we're now getting second, third generation showing up because it's been since 1975.

Yeah, it's pretty terrifying. It really is.

I mean, I feel we have to ban this chemical worldwide right now. I mean, if we have any hope for the future, I feel like we really need to wake up and realize this is the thing that's causing all the problems that we're seeing. And it shocks me that we see all this obesity. Like this country is just so many problems with obesity. and, and we just think, oh, we're just watching too much TV and eating too much popcorn. I mean, that's just, like, really ridiculous to think that could be the reason why we have such a tremendous inability to keep the weight off. Yeah.

Well, there's a whole science field called the study of obesogens. And obesogens are environmental chemicals that cause obesity. I've written a lot about this over the years, even, you know, 15, 16 years ago, I wrote about it, because I used to see it in my patients. And when you start to improve their detoxification and get rid of these chemicals from their body, they actually do better. Their metabolism improves, their weight loss comes off. But what you're really saying is that most of us have levels of glyphosate in our bodies, including you and I, that do impair human health. And I'm sure people listening are wondering, what the heck can I do about it other than, you know, like if Dr. Hyman and Stephanie, who's an MIT professor who's made her life's work to study this, have high levels, what the heck am I going to do?

I know. It seems really hopeless. I was so depressed when I found that I was contaminated. It wasn't high. But it was there, it was measurable. And it's just really depressing that you can't avoid it, which I think is the case. If you live in America, I mean, there are places in the world where you probably can, but it's very difficult to find a place here that without it. It's in the rain. It's in the rain, it's in the.

Water, it's in the atmosphere, it's in their food.

There was a study in Brazil found it in the atmosphere, found it in the nanoparticles in the air in Brazil. as well.

Is the majority, though, from our food that we get it?

I think so, but I'm not sure. I mean, that's always been my big question. I think people who live next to fields where it's being sprayed are in serious trouble and they're going to get things like chronic obstructive pulmonary disease because they're breathing, breathing glyphosate. But I think most of us are getting it through our food and possibly through our water. I mean, there's a question of a water supply and it could also be from the air. And I'm concerned about that with respect to biofuels because I'm really quite wondering if biofuels introducing glyphosate into the air in cities where they're being burned because they're coming from, like for example, ethanol, bioethanol is coming from GMO roundup ready corn or sugarcane sprayed with glyphosate right before the harvest. So it could be in the atmosphere. I mean, it is in the atmosphere and it could be from the air that you're getting exposure into the lungs.

And that's another word that I have. So is there a way for us, is there anything we can do, eat, take supplements, anything that can help us reduce our glyphosate levels, take a sauna, wheat grass enema, What are we going to do?

Yeah, I mean, I'm a big fan of sunlight and of course vitamin D is so important, but I believe sunlight also helps you to make sulfate in the skin. I talk about that in my book, quite fascinating science. And so sunlight exposure, I think, is extremely useful for improving your immune function. Your immune function is really central to your health. Many people in America have a weak innate immune system and that's causing a lot of their diseases. Their diseases are actually are there to help boost the immune function. They serve the immune cells to help improve their health. I believe, you know, all these diseases like arthritis and things, gut dysbiosis and et cetera. So we'd be taking, for example, sulfur.

Producing sub compounds that help boost glutathione like lipoic acid and acetyl cysteine. Yes, right. We'd be taking the methylene vitamin B.

Vitamins to help with that sulfur and glutathione. Right, make sure you have a methylene. I like to just eat really, really healthy foods, you know, certified organic, whole foods, lots of green vegetables, lots of supplements.

But is that enough though? I mean, is that enough because you've been doing that already? So, I'm thinking, okay, from my functional medicine perspective, how can I fix these problems?

Glycine is another one, you know, taking glycine, that's one that I've talked to functional medicine specialists who like glycine as a supplement. Yeah, I love it. Yeah, because that's going to help to.

Counteract the glyphosate substitution for the glycine, which is so important to try to prevent. you can take amino acids of glycine. You can take sulfur boosting compounds like NAC, lipoic acid, selenium, milk thistle, Epsom salt baths, Epsom salt baths, vitamin D. These are all things people can do and plus just cut out your exposures.

As much as possible. And then probiotics.

Yeah. Yeah.

Cut out exposure is crucial. Try everything you can to cut out exposure. And then probiotics, especially, it's curious that there was a study on cows that found that sauerkraut juice was beneficial for cows that were, I can't imagine these cows eating saucerkraut, but they were sick and they had glyphosate in their urine and they gave them several things. But saucerkraut juice was one of the things they gave them. And I don't know how they thought to do that, but I found that quite interesting because I was wondering whether, and it hasn't been proven, whether the microbes in the saucerkraut juice were able to metabolize the glyphosate. I feel like if you could get microbes growing in your gut that can metabolize glyphosate, you would be a lot better off. And so, there are species of acetobacter that can metabolize glyphosate. So one could hope they might be in apple cider vinegar, you know, Munted foods. It's a possibility. It hasn't been proven, but it's something that I find appealing.

So, so we need a multi-pungent approach, right? Yes. Okay, so let's sort of switch gears a little bit for a minute. So we talk about the human health impacts, but let's talk about the environmental impacts. Why is glyphosate such a threat to our environment, the wildlife and biodiversity, and.

The microbiome of the soil? And why is that important? Right. I mean, that just goes so far, doesn't it? I mean, because the soil, if the soil isn't healthy, then the plant isn't healthy, then the food isn't healthy, and it just cascades downward. There's so many animals that are in trouble right now. There's such a mess with the insects, you know, the bees, the bee colony collapse syndrome, the butterflies are disappearing. I believe many of those problems that glyphosate is a major player in many of those problems. People have always looked elsewhere and certainly there are other chemicals that are affecting them. You know, the insecticides are an obvious one for the bees, but lately it's becoming clear that glyphosate is a player in the bee colony collapse syndrome. and it's quite clear with a monarch butterfly because glyphosate is used to kill its major source of food as a weed. You know, the milkweed is a weed that grows in the corn crops and they use glyphosate to kill it. The butterfly depends on the milkweed as, as its diet. The milkweed is poisoned with glyphosate. So, so is the butterfly. Monarchs are disappearing. Insects are way down. It's just, it's. And, of course, the amphibians, they're very sensitive to glyphosate because they they breathe, they take in water through their skin and, and they think their skin is very porous, so they get, they get the glyphosate probably goes right in through their skin.

So it affects wildlife, it affects pollinators, it affects reptiles, biodiversity. I mean, we need pollinators for, for fertilizing agriculture. Um, it's a lot of ways in which it screws things up. To me, one of the most important ways is the soil. And we've talked a lot about soil, the importance of the health of the soil, the organic matter in the soil determines the quality of the food we eat, our quality of our health. It's also necessary for the sequestration of carbon in the soil.

Right.

We're holding water for reducing the effect of chemicals. So glyphosate seems to have a really horrible effect on soil and the soil microbiome as well as our own microbiome. So can you talk about that and why that's important?

I can, yes. In fact, In fact, it disrupts the ability for the plants to take up the nitrogen fixing bacteria get disrupted. So the nitrogen is not easily taken up by the plants. And this means you have to use more nitrate fertilizers and that they stick around. And then when there's a rainstorm, they wash out into the waterways. And this, and actually we have a huge problem with the overgrowth of cyanobacteria because of the nutrients that are being supplied. They sort of block the sun and then you get into, and they use up the oxygen. So you have this hypoxic environment in the waterways that ends up reducing producing nitrous oxide from that nitric oxide. From that nitrate fertilizer, it produces nitrous oxide, which is a hundred times worse than carbon dioxide as a greenhouse gas. So that's getting released. So it's messing up climate change as well. In fact, glyphosate just suppresses an enzyme, which is the most common enzyme in the world. It's called Rubisco. It's a nice name. R-U-B-I-S-C-O. Rubisco. It's an enzyme that's present in many plants, and it's essential for converting carbon dioxide into organic matter. So it's preventing the plants from capturing the carbon dioxide in the air and putting it into the soil. And that's, of course, a crucial way to avoid carbon release, carbon, you know, global warming from these greenhouse gases. I think I suspect that glyphosate is playing a major role in the crisis we're seeing with carbon dioxide. I don't know if you heard, but the carbon dioxide levels on the top of this mountain in Hawaii have the highest levels ever measured happened this April, this month, despite the fact that we've shut way down on the, you know, because of their lockdowns, we have a lot more, a lot less burning of fossil fuels in our vehicles. And despite that, the levels keep going up. I think that I think glyphosate is a major player in climate change. And I'm frustrated that nobody seems to.

Be looking at that.

Because of its effect on the soil health, you mean?

Yeah.

Capturing carbon from carbon dioxide in the air, capturing it, turning it into organic matter, putting it into the soil. This is a process that goes on in all the plants all over the planet. and when glyphosate is there, it suppresses their ability to do that.

Yeah, I mean, a lot of, a lot of people listening to this podcast have heard me talk about regenerative agriculture and the importance of soil health. And we've got a lot of soil experts on the podcast. And, and, and, you know, we've talked about the reasons for degraded soil health, tillage and lack of COVID crops and lack of animal integration and lots of other things, but, and even nitrous nitrogen fertilizers. But glyphosate seems to be one of the worst actors in terms of damaging the microbiome of the soil, which is intimately linked to our health and our biome, but also is critical, as you said, without the organic matter in the soil, which is really the microbes and the carbon from the plants, we can't want to extract nutrients from the plants. Well, we can't hold carbon in the soil, we can't hold water in the soil, and we need all these agrochemicals. So in a sense, glyphosate is the kingpin that can help unlock this.

And it also causes the soil to erode much more easily, erode, so we lose topsoil. No, because it doesn't have enough organic matter to hold it in place and hold water.

That's true. Now Monsanto, which is now gone and is a new company, has been bought by Bayer, which is the same company makes your aspirin, by the way.

Yes.

But it's a big agrichemical company. They seem to have bought this when it was undergoing a lot of review and lawsuits and took on a huge risk and and yet they seem to be okay with it. And they also have been looking like maybe they might shut down glyphosate, but they've come up with another compound called Liberty Link, which is another herbicide that they want to replace glyphosate with. And it's starting to be used all over America and globally. What's your take on that? 'Cause it's like, you know, it's a new thing, maybe it's better, maybe it's worse, but I don't trust it.

Is that one glyphosate? glucosinolate?

I'm not sure the chemical name for it.

You can look it up, but it's- I was thinking it is, but I need to do a quick Google search to see. Yeah. Glucosinolate is also an amino acid analog, by the way. It's an amino acid analog of glutamate. And I suspect it's going to have a similar property of substituting for glutamate during protein synthesis, just as glyphosate is substituting for glycine.

It's possible that it's going to do that.

All these chemicals are bad. Yes, it's glucosinolate. It's glucosinolate.

Glutamate.

It's an amino acid analog of glutamate. Of course, glutamate, you know, glutamate is a major player in autism because there's excess glutamate in the brain. It causes neuroexcitotoxicity. Glutamate is bad news.

I mean, none of these herbicides are good. It's a new better one, but it's not good. So, so what do we do? We have to change our agriculture to a more regenerative system that doesn't need all that crap. And when you look at the farmers like Gay Brown, Alan Williams, and a lot of the regenerative farmers, they're actually phasing out all these compounds. They're phasing out these roundup ready seeds and they're phasing use of agrochemicals and they're seeing better yields, increased soil carbon, lower water use and water retention in soil is better, improving the nutritional density of the products. They're making more money and they're actually drawing down sequestering carbon as part of the cycle of regenerating soil. So, I mean, why is the government not doing this? And other countries have really, other countries have really taken a stand on this. What countries have banned it and what do we need to do to get it banned here?

Right. So Bermuda has banned it since I think to 2000, at least 2015. Bermuda has just not used glyphosate. I think they care about their coral and trying to protect it. Sri Lanka and El Salvador banned it some time ago off and on. They kind of banned it and unbanned it because of kidney failure among the agricultural workers that were being exposed to glyphosate. And Mexico is such a darling. I'm so happy to hear that Mexico just declared maybe last year they're going to phase glyphosate out by 2024. And they're also going to phase out the GMO corn as well. So Europe has been trying to ban it. And that's kind of a sad story because I think Austria banned it and then basically, or they passed a law to ban it. And then I think higher ups at the European Union basically said, you can't do that or you did it wrong or something. So, you know, the European Union is trying to gain wrestle control over all those countries so that individual countries can't make individual decisions. which I think is really sad.

So Mexico, the environmental working group, I mean, sorry, the EPA has basically sort of taken a backseat on this and has said it's safe and it's not an issue. And there were emails that were discovered under the Freedom of Information Act in a lawsuit that found that the Trump administration was emailing Bayer saying, don't worry, we got your back on glyphosate.

I heard that.

I know. like, whoa. So maybe your book will help us to call this out in a way that people can understand and that will catalyze lawmakers and policymakers. And I personally am going to help you with my efforts in Washington to help educate lawmakers about the dangers of life of state and begin to sort of hopefully turn the tide on this. And it really comes down to one, supporting a different form of agriculture, like regenerative agriculture, but also, but also, to really help with driving the regulations that have to stop the use of it in this country. But 9 billion pounds is a hell of a lot. Kilograms, actually, that's more than 9 billion pounds. So basically, here we go. We've gotten bird's eye view, just really touched on it in the most superficial way, really. body should get this book, Toxic Legacy, which is the subtitle is how the weed killer glyphosate is destroying our health and the environment. It's out, get it wherever you get your books, Amazon. It's such an important book for our time. And I think hopefully it'll be a catalyst to one help people change their own behavior and change policy. And as sort of the take homes for people listening is that one, it disrupts so many of the body's key systems, mitochondria and energy, your immune system, your microbiome, your hormones, your oxidative stress, your detoxification pathways. But the good news is we know a lot through our understanding of biology and functional medicine how to help the body detoxify. So while you may not be able to get rid of it completely, you can reduce your exposures by eating regenerative organic. You can make sure you are up regulating your pathways that need to be up regulated, such as the glutathione pathway with lipoic acid, selenium, milk thistle, and acetyl cysteine, even glutathione sublinguals. daily, as well as the B vitamins. We know you also need things like Epsom salt baths, vitamin D, and lots of other things to help. So I'm sure all that's in your book. I'm super excited to get this out in the hands of everybody, and I'm so thankful you've done the hard work and the science behind this and taking this on because you could be a Target for something, you know, because of what you're saying. So thank you so much, Stephanie, and, and I love having you on the podcast. Any last thoughts or words you'd like to share about your work or what people we can learn more.

It's hard to say, but I just really want to have hope for the future and I'm so excited about the regenerative agriculture. I think we need to be positive. We need to understand that it's not hopeless. And if we do manage to get the product banned and not adding more, and then we learn how to remove what's there, and then we learn how to fix the soil and grow healthy food and then be healthy and reduce our healthcare costs. I mean, there's nothing not to like about that. We just need to get lots of people on board, need to get the government on board to recognize that toxic chemicals have no place in our food supply.

Well, thank you so much. And the book is now number one in the agriculture industry on Amazon. I encourage you to just definitely get it. It's so important a book.
