Most Replayed Moment: Mouthwash REVERSES The Benefits Of Exercise! Dr Nathan Bryan

If I've just listened to everything you've just said there, and I want to improve my oral microbiome, what should I be doing? Well, I think the most important thing we've earned is what you shouldn't be doing. Yeah. Right. It says, no, what should we do? It's what we shouldn't be doing. Number one, we have to get rid of fluoride. You know, just this past weekend, I was speaking at a dental conference in Salt Lake City, and there were people there from the National Toxicology Program, which in the US is the organization tasked with, if there's any kind of risk of exposure of a environmental toxicant, they're charged with doing the toxicology studies to see if there's an increased risk. What is the risk? And is there a safe level that is without risk? And what they report is that fluoride, there's no benefit of fluoride, and it's all risk. It lowers IQ in kids by as much as seven points, and it shuts down your thyroid function. And it's a neurotoxin. And as I mentioned before, most toothpaste has fluoride in it, and if you read the back of your toothpaste, it will tell you, at least in the US, I don't know about in other countries, but it says, if you swallow this, call poison control, because it's a poison, they're putting poison in toothpaste. And then if you also pay attention, it says, only put a pea-sized amount of toothpaste on your toothbrush, a pea-sized. But everybody that I know fills the entire bristle of the toothpaste with toothpaste. So that's about 10 or 15, sometimes 20 pea-sized amounts of toothpaste. And a pea-sized amount of toothpaste contains about half a milligram of fluoride. Now, if you're using 10, 20 times more than that pea-sized, now you're exposed to five milligrams, 10 milligrams of fluoride, and you don't even have to swallow it. This is a very small molecule, a molecular weight of 19. So it's absorbed directly across the bucule mucosa, the oral cavity, and it becomes systemic. I'm not going to use it anymore. No, you shouldn't. What should I use instead? You have to use a non-flornated toothpaste. And what about things like tongue scrapers? Now, tongue scrapers, the data, again, that's time-tested, that's an ancient practice. And even in our study, we found that people who do tongue scraping have a more diverse oral microbiome, and they seem to have better oral health. What is this? My girlfriend's been banging on to me. She's always bloody right. My girlfriend's been banging on to me about tongue scraping for the last two years, and I've kind of just ignored her. I've just kind of... Yeah, baby, sure. And when she's not in the bathroom, I'm not using her tongue scraper, because it just looks strange. And for me, based on what I knew about the oral microbiome in the microbiome, generally, I'm like, should I be scraping off all my bacteria? Well, if you're going to plant a garden, do you plant a garden on untilled soil? I don't know. Nothing about gardening. Yeah. So maybe... I grew my own food. Okay. So you have to till the soil. Right? You got to break up the soil so the seeds actually can be aerated, and you break up that bio film. Yeah. You take the back of the dorsal tongue. I mean, almost to the point of the gag reflex, and you just pull that, ideally, copper tongue scraper forward, and you're going to see this goop coming in there, but it's kind of like tilling the soil, and it's increasing the diversity of the dorsal part of the tongue, the microbiome. So my girlfriend was right. In that regard, yes. But what we found was in that one kid, we saw the greatest increase in blood pressure. If you tongue scrape and use antiseptic mouthwash, that's the absolute worst scenario. Interesting. So if you think about this, you're tongue scraping, you're opening up the pores, and now you're using mouthwash, it's better to easily penetrate deep in the crypts of the tongue, and more effectively kill the bacteria. So you want to tongue scrape, and then use a toothbrush without fluoride toothpaste? Absolutely. And no mouth. No antiseptic mouth rinse. Thank you. And what about going to dental hygienists and things like that? Do you think that's an advisable idea? Because once every quarter or so, I'll go and see dental hygienists just to get everything sort of cleaned out. No, I think that's a good proactive practice, but because you need to look at the health of the gum tissue and the gingival tissue and a routine clean and scraping the plaque off the teeth and making sure you have good mineralization of the enamel of the tooth is good, but never let them do a fluoride rinse on you. Is there anything else on the subject of the oral microbiome in its relationship with nitric oxide that I need to be aware of before we move on? There's also data showing that if you use mouthwash, you lose the cardiovascular benefits of exercise. So think about this. We know that diet and exercise is the best medicine. And many people aspire to do that. They go and they try to eat good. They avoid the temptations of sugars and sweets. They exercise every day to try to increase their longevity and cardiovascular health. If you do that and you're using mouthwash, you no longer get the benefits from exercise. And we've already established you don't get the nitric oxide benefits from diet. So two out of three Americans wake up every morning and use mouthwash. And two out of three Americans have an unsafe elevation of blood pressure. What's the mechanism now? Well, because you're killing the oral microbiome that's partly responsible for production of nitric oxide, and nitric oxide, you get constriction of blood vessels, and it leads to high blood pressure. That's crazy. And is there a link between our hormone levels, things like my testosterone levels, and the nitric oxide? Yes. So this is the two way street. So in men testosterone activates nitric oxide production. Okay. In women, estrogen activates and stimulates nitric oxide production. Okay. So as long as we have optimal sex hormones, and as long as the enzyme and the lying in the blood vessel can functionally produce nitric oxide, that explains the cardio protective benefits of hormone replacement therapy. Got you. So taking testosterone or estrogen therapies helps to increase my nitric oxide levels. As long as the enzyme is functional and coupled, which means that we have to understand the insomology and about chemistry of that reaction to where when it's exposed to testosterone, the cell can actually make nitric oxide in response. And there's a two way relationship as well with exercise, then, because I've read in your book that exercise activates and stimulates nitric oxide production, but you also just told me that if you want to get the great benefits of exercise, you need nitric oxide in the first place, because else your blood cells are going to be very narrow, less oxygen traveling through you. You're going to do a worse workout as well, originally. Yeah. Well, think about, I mean, there's other agonist too, like vitamin D. I mean, most American's are deficient vitamin D. People with low testosterone have a rectal dysfunction. Why is that? Because they're not stimulating nitric oxide production and they're not dilating the blood vessels. So they develop ED. So all of this, no matter what it is, with related to vitamin D deficiency, which is activated or stimulative nitric oxide, if it's low hormones, if it's poor diet, sedentary lifestyle, all of that can be explained by insufficient nitric oxide production. Well, when I think about the role that food plays in my nitric oxide production, what should I be eating to increase my nitric oxide levels, or to keep them at a healthy level? I think the same answer is for that too. It's not so much what we should be eating, it's what we should not be eating. Okay. So we'll cover those step by step. Number one, you have to avoid sugar and high glycemic index foods, because sugar is a toxin, it's a poison, and let's think about what sugar is. So when we eat sugar or drink sugar beverages, whether it's sucrose, whether it's fructose, whether it's high fructose cornstripe, the end result inside the human is we see an increase in glucose. So elevation in blood sugar or blood glucose is diabetes, right? And now there's continuous glucose monitors that you can get anywhere, and everybody does this. So if you eat something and it causes an increase in your blood sugar, blood glucose, then you should avoid that, because glucose, as the name applies, is glue, right? It's sticky. And if we, if you have a soda and you spill it on your countertop, you come back the next day, it's sticky, right? That's what happens inside the body. That sugar sticks to everything, it sticks to proteins, it sticks to enzymes, it binds to hemoglobin. And sugar stuck to hemoglobin is what we call hemoglobin A1C. And what is that? It's a marker of long-term glucose control. If you have a hemoglobin A1C of greater than 5.7, you're diabetic. So it's not just hemoglobin, it sticks to, it sticks to the enzyme that makes nitric oxide. And in biochemistry and enzymology, enzymes have to be able to undergo conformational changes, right? So it transfers electrons from one donor to an acceptor and that's how biochemistry is done. But if sugar stuck to that enzyme, it locks it in some confirmation and it can't do its job for instance, it can't make nitric oxide. So sugar is an absolute poison and it kills many enzymes and binds to everything. And it lowers nitric oxide production? Absolutely. That's why diabetics have a 10-time higher incidence of heart attack, stroke, all-cause mortality, mortality. That's why they develop neurological or peripheral neuropathy. That's why they have non-healing wounds. There's no nitric oxide. That's why they're developing diabetic retinopathy. They're the generation. Pancreatitis. I mean, all of that can be traced back to a lack of nitric oxide production because the sugars stuck to the enzyme, the sugar destroys the oral microbiome and completely changes the ecology of the bacteria and completely shuts down nitric oxide production. Just a bit of a tangent there. You mentioned, that's why they have open wounds that don't need... Yeah, diabetic ulcers. Okay. You know, nitric oxide's playing a healing role in wounds and scar. Absolutely. So I've got this scar on my head. I was playing football the other day. Someone ran into the back of my head and they passed out and got taken away by an ambulance. But I was just left with this big, like, scar on the back of my head, which I've had like glue stitched. Yeah. So I'm wondering, I'm like, if I... Apply the nitric oxide syrup. It'll stimulate blood flow to that. It'll improve cellular turnover and heal that wound and basically remediate the scar. And how do I do that? Is it... Yeah. You see, take one pump from each side. So one pump from this side? We'll turn it around, one pump from the other. Yeah. And now if you apply that and mix it together, as soon as you mix it together, it starts to generate nitric oxide gas. So then that gas will diffuse into that tissue. It's going to increase blood flow and it's going to mobilize stem cells and it's going to improve cellular turnover and completely remodel that and heal that. And if it were an infection in there, it would kill the infectious bacteria. Okay. Well, we shall... Second boss. We shall see if that works. So back on this point of food then, sugar is bad. Sugar is bad. Yeah. You got to eliminate sugar. And I think the benefits of it, like a straight ketogenic diet or a straight vegan vegetarian diet, is just the elimination of sugaring carbs. Yeah. Right? But I think to answer your question, what should we be eating? I think you've got to eat a balanced diet in moderation. You know, Americans are overfed. All you've got to do is walk around and see the epidemic of obesity. Good high quality protein, good quality fats, and little or no carbs. And it's really that simple. And why did you write a book about beetroots? Yeah. The beet hit the, really the airways back in 2012 in the London Olympic Games. There was a lot of data coming out at the time of the benefits of beetroot juice on enhancing athletic performance. But there was a benefit of the nitric oxide being produced that could explain the improvement in athletic performance. The problem is these athletes were drinking leaders and leaders of beetroot juice and causing a lot of gastric discomfort, causing diarrhea. Their urine and their feces would turn red and a lot of people interpreted, misinterpreted that as gastric bleeds or urinary bleeds. And then when I started looking at the products on the market, most of the beet products, the desiccated beet powders provided zero nitric oxide benefit. They didn't contain any nitrate, no nitrite. They were just, we call them deadbeats. They're deadbeat product. And so I thought if people, if consumers are out there looking for beets because they've been shown to enhance their performance, but that enhancement and performance was dependent upon the beets ability to improve nitric oxide production in the body, then the non-scientist out there wouldn't know what to look for. They're buying products that aren't providing any benefit to them. And so years ago, we would do randomized placebo-controlled clinical trials and we would take some of these commercial beet products that you can go to your local nutrition store or pharmacy, buy off the shelf and we would use those as placebo in our clinical trials because it's the perfect placebo. So what I tried to do in that book is educate, okay, what is it about beets that are so important, the mechanism and what is necessary in those beets that can improve nitric oxide production. So again, everything I do is intended to educate and inform the consumer so that they know how to make informed educated choices on the products they're taking or the foods they're eating or their oral hygienic practices. I'm trying to find the page in your book, but there was a page in your book where you describe beetroot as the most under-appreciated food in the history of eating. Yeah, that may be in the Beet the Odds, but if you go back to historical times and you look at the hieroglyphics of the ancient cavemen, people thought they were drinking wine because they would have these red stuff in this before battle. But what these ancient Egyptians were doing was they were drinking beet juice to improve their performance before they went into battle so that they were ready, they were energized, they improved their circulation. So that's the historical study on beets. And obviously, these were beets grown at a time when there were no herbicides, pesticides and the soil was probably fertile, so these beets were full of nutrients, probably full of nitrate that provided the benefits of that. And unfortunately, today, the beets that are grown, at least in America, really are nutrient depleted just like most of the food. So would you recommend people eat beetroots? No, because, again, through our survey that we published in 2015, we realized that you really can't eat enough beets to get enough nitrate to improve your performance. And the other caveat is that if you're using mouthwash, you've got fluoride in your toothpaste or fluoride in your drinking water that you're mixing the beet powder in, you're not going to get an nitric oxide benefit from it. There's a graph in front of me here, which I printed off, which shows the rise in antacid medications. Oh, yeah, from 2004 to, so a 20-year period, we're seeing what is it, almost a quadrupling of the use of antacids, and this is globally, or is this in the US? That's worldwide, I believe. Yeah, worldwide. Now, this is a problem. I mean, these, these antacids, what is an antacid? So it's a medication that's given orally to suppress stomach acid production. Yeah. And as a biochemist and physiologist, I can't think of nothing more damaging than to inhibit stomach acid production. Because stomach acid isn't required to break down proteins into amino acids, whether it's you're eating animal protein or plant-based protein, it's required for nutrient absorption. You need stomach acid to absorb B vitamins. You need stomach acid to absorb selenium, chromium, iodine, magnesium, iron. I mean, most nutrients, micronutrients are absorbed in the lumen of the stomach. And if the stomach is not making stomach acid, then these nutrients are not absorbed. And most Americans, 75% of Americans are deficient in magnesium. 95% of Americans are deficient in iodine. I mean, it's a huge problem. These are the browns like gavaskung. Now, these are like the prylosec, the prevacids, the nexem, the prescription medications are Omepersol, Pantopersol. These, today in the U.S., I think, is probably worldwide. You don't even need a prescription for these from your physician. You can go to your local drug store and you can buy these, what we call proton pump inhibitors or PPI's. Where about tombs? Over the current. So there's a difference. And so, tombs and things like baking soda are a buffer, sodium bicarb or calcium carbonate. And it's a buffer. So if you have an acute bout of hypersecretion of acid, you can take a tombs or some buffer, some base, alkaline substance, to neutralize the acid. Neutralizing acid is completely different than inhibiting its natural production in the polyurexyls of the stomach. So what is the difference between, so have you heard of gavaskung before? Yes. Yeah. What's the difference between, like, a gavaskung? Well, there's certain classes of anacids. There's what we call H2 blockers. There's proton pump inhibitors. And then there's the natural buffers that are just kind of neutralizing the acid environment in the stomach. Gavaskung, I'm trying to think, what class that falls under. I don't think it's widely used here in the U.S. I mean, the main drugs used here are prolacic nexem, prevacid. Those are the over-the-counter. And then the main prescription medications are the omeprosol and the pentoprosol. Gavaskung is a commonly used antacid brand, and the active ingredients are aluminium-hyde peroxide and magnesium carb carbonate. Oh, so Gavaskung. So number one, it's got aluminum in it, which should absolutely be avoided. But yeah, it just looks like a buffer. It's got an hydroxide, aluminum hydroxide, which is a strong base. So it's neutralizing the stomach acid production. But it's a neutralizing agent, but anything that contains aluminum, you should absolutely avoid. I mentioned it a few times today, but my girlfriend's a breath practitioner, she runs a business called barliebreathwork.com, ashtagad. And one of the things she's talked to me a lot about is mouth breathing. And I know there's a relationship between nitrog oxide and how we choose to breathe, whether it's through our nose or through our mouths. Can you explain to me that link? When we talk about the enzyme that's found in the lining of the blood vessels, we sort of this segment. That same enzyme is found in our epithelial cells, in our upper airways, in our sinuses. So just like exercise can activate nitrog oxide production in the lining of the blood vessels, deep breathing, nasal breathing activates that enzyme in the epithelial cells of our sinuses. And so when we do nasal breathing, it's activating the enzyme to make nitrog oxide. Now we're delivering that nitrog oxide gas into the the brockles, the lower airway. It's dilating those brockles. Moreover, it's dilating the pulmonary arteries. So now we're improving oxygen uptake, oxygen delivery. And that's why nasal breathing and deep breathing has been shown to lower blood pressure. This is a pretty crazy graph I took from Google as well, which shows just how interested people are now getting in the subject of mouth breathing. Oh, yeah. Again, going over the past 20 years. Yeah. No, I think there's a lot of people. I mean, obviously your girlfriend, there's a Patrick McKeown in the UK. I came in to Dragonstone. I did it, made him an offer in Dragonstone. Yeah. No, I think the benefits of that are pretty well. And mechanistically, we understand the benefits of it. So the mouth breathers are not only bypassing the natural nitrog oxide production pathway, but when you mouth breathe, it completely changes the microbiome. And so you're not only bypassing the nitrog oxide producing in the upper airway, but you're inhibiting nitrog oxide production in the mouth from the microbiome. Because you're fully oxygenating the mouth, it's changing the pH of the saliva and completely changes the microbiome and completely shuts down nitrog oxide production. Interesting. Interesting. So you have to, I mean, I'm a big fan of mouth taping. But for me, I know, and I watch my kids, but sometimes there's anatomical issues where there's obstructive airways and airway obstruction that has to be corrected by dental appliances or sometimes surgery. But the worst thing you can do is tape your mouth and your airway be constricted and suffocate. So before you do mouth taping, you need to get some imaging done from your dentist to make sure that your airway is open to where if you're forced to breathe through your nose, you can actually have oxygen exchange. And is there anything else that I could and should be doing to increase and improve my nitric oxide levels that we haven't talked about yet? Humming. You know, there are certain frequencies. We've done this and looking at nitric oxide coming out of the exhaled breath when you're humming. So certain frequencies can activate this enzyme and it's dependent upon the volume of the nasal sinuses. So there's not one frequency that would work in every single person because the volume of your airways and oral cavity and sinuses was probably much different than mine. Give me an example. Show me. Well, if you just, you know, like, ohms, like you do in meditation or just simple humming, you could actually, so if I had my ozone or gas phase analyzer here, I could hum and I could detect nitric oxide coming out of my exhaled breath because of the frequency. Because of the frequency and activating the nitric oxide synthase enzyme. But if you take older patients and we've demonstrated this, it's published years and other groups have demonstrated this, older patients that their enzyme isn't making nitric oxide, whether they do nasal breathing or whether they do humming, there's no nitric oxide coming out. So again, this is an activator and a stimulator, but it's dependent upon the function of the enzyme that makes nitric oxide. If your enzyme is broken, humming, nasal breathing, exercise isn't going to produce any nitric oxide. Is there anything else that I should be aware of if I'm trying to improve my nitric oxide levels? I think it's doing the things that disrupt it. Get rid of fluoride, get rid of mouthwash, stop using in acids, stop eating sugar, anything that leads to an elevation and blood sugar, a balanced diet and moderation, moderate physical exercise, 20-30 minutes of sunlight a day. Sunlight. Sunlight, there's certain, at both ends of the visible spectrum, both the UV spectrum and the full spectrum infrared. So those frequencies and vibrations, again, stimulate nitric oxide release. So the UV has enough energy to riddle, it'll knock nitric oxide bound to a assisting thiol and protein, and then the UV spectrum will release nitric oxide bound to metals. So you mean go out in the sunshine, but also those red light beds and stuff? Yeah, they're red light. I have a red light bed. I have an infrared sauna that uses red lights in it, and I use it every day. Full nitric oxide production. Yeah. And there's other benefits of light. You know, it can stimulate mitochondrial biogenesis, it improves energy production, it can lower blood pressure, but you also benefits of light therapy. And yet, we're programmed to not go outside, if we go outside, put on SPF 60 and intoxicate ourselves with these cancer-causing chemicals and sunscreen, I mean, it makes no sense. What you just listened to was a most replayed moment from a previous episode. If you want to listen to that full episode, I've linked it down below. Check the description. Thank you.
