• Is blue light damaging your eyesight?

  Over the past decade, most of us have converted our home lighting to light-emitting diode (LED) bulbs, as they save a significant amount of energy, requiring 75-90% less energy than older incandescent lights. Personally, I converted the 50 or lightbulbs in my house to nearly all LEDs.Most current LEDs emit, of course, visible light. But they also emit a significant amount of blue light and very little red and infrared (IR), in contrast to old-fashioned incandescent bulbs that emit some blue and a lot of red and IR. Remember when you had to change an incandescent bulb when it died? If you tried to unscrew it, it could burn your hand because the bulb was extremely hot. That’s the effect of red and IR that generates heat. Change a LED bulb and you can do so immediately, as the bulb is cool, even after dying just moments earlier. This is due to the absence of significant amounts of red and IR.While well-intended to save energy, it is now becoming clear that the wholesale conversion to blue-emitting LED lighting has been exerting adverse health effects, especially visual. So let’s begin talking about the role of light, specifically blue wavelengths in this episode of the Defiant Health podcast, then about the role of red and IR in a future episode. _______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

• Managing Endotoxemia: Key to SO Many Aspects of Health

  I’ve touched on the topic of endotoxemia in past episodes of the Defiant Health podcast. In this episode, let’s dive deeper into this topic that is absolutely crucial to understanding and managing SO many aspects of health, from subduing anxiety and panic, to depressive, to joint pain and skin rashes, to gastrointestinal conditions, even weight management. What is endotoxemia? Fecal microbes, so-called Gram-negative species because of the way these microbes take up stain for examination under a microscope, species such as E. coli and Salmonella, have something called lipopolysaccharide endotoxin in their cells walls. Other species, so-called Gram positive species such as Enterococcus, Staphylococcus, and Streptococcus, that stain in a different manner, have something called lipoteichoic acid in their cell walls. When these microbes die, both Gram-negative and Gram-positive, these toxic factors are released into the intestines. If these fecal microbes are confined to the colon, where they belong, a section of GI tract adapted to their presence, the entry of these toxic components are limited and current evidence is unclear in how importat this process is. The real trouble occurs, however, when fecal microbes have invaded the 24-feet of small intestine, a process we label small intetinal bacterial overgrowth, or SIBO, because the small intestine—the stomach, duodenum, jejunum, and ileum are not well-adapted to the invasion of fecal species. Here, they die, release their toxic components, which then enter the bloodstream, the process labeled endotoxemia. People with SIBO therefore have high blood levels of endotoxin. This is how microbes in the GI Tract export their effects to other parts of the body. Let’s discuss this process and how you can take control over your emotions, mood, sleep, energy, weight, and numerous other aspects of health. _______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

• Why managing skin pH is crucial for skin health and appearance

  I’ve been showing thousands of people how to restore this microbe lost by the majority of modern people, Lactobacillus reuteri. But, of all the spectacular improvements in health we can gain by managing our microbiomes, such as an increase in empathy and generosity, reduction in anxiety and depression, deeper sleep, increased libido, restored youthful musculature and strength, the females in my audience have repeatedly said something like, “Well, that’s all well and good, but I’m mostly interested in the skin benefits.” So I’ve spent a good deal of time, energy, and resources in exploring this question, including performing a small human clinical trial to better understand how and why restoration of L. reuteri, especially when combined with other non-microbial synergistic factors, can restore youthful healthy skin. One issue that has emerged to the forefront in our quest to better under skin health and appearance is the issue of skin pH. We may not think about skin this way, but healthy skin is acidic. The pH of healthy skin in someone not plagued by eczema, acne, rosacea, psoriasis, or other skin conditions is typically around 4.5. Recall that neutral is 7.0 and the blood is mildly alkaline at a pH of 7.4. Unhealthy skin, in contrast, skin with various skin rashes, has a pH of around 5.5—given the logarithmic nature of the pH scale, unhealthy skin is therefore 10-fold less acidic than healthy skin, a huge difference. This difference in pH is a crucial determinant of what you skin looks and feels like, whether you will be prone to these sorts of skin rashes or whether you can enjoy smooth youthful skin. So let’s dive into that topic, the importance of managing skin pH._______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

• The curious phenomenon of bacterial translocation that is key to so many health conditions

  I’ve spent some time reflecting back on all my years practicing in hospitals, often not sleeping for extended periods, sometimes days, covering hospitals floors and ICUs, resuscitating people who experienced cardiac arrests, taking them to the cath lab to open arteries, but also witnessing people with all sorts of other health conditions: cancers, wound infections, sepsis, delirium, the various stages of dementia, and hundreds of other debilitating disease. I now recognize that, looking back, so many health conditions can be better understood in light of the contribution of the microbiome, i.e., the trillions of microbes occupying the gastrointestinal tract from mouth to anus, the nasal sinuses, the airways, the brain, the prostate, the vagina and uterus, the skin—virtually every part of the human body. We all know about acute bacterial infections. But I’m talking about something different. While microbes exert effects via a number of different routes—think the gut-brain axis, the gut-skin axis, the gut-muscle axis, effects exerted via hormones, inflammatory mediating proteins, and bacterial breakdown products. But beyond this, there is a curious phenomenon in which bacteria and fungi themselves, by a number of means, travel through the body to take up residence and cause trouble. But the “trouble” is not an infection in the conventional sense, but something different, less acute, less urgent, less dramatic, but nonetheless playing a big role in your health. This is the fascinating and scary phenomenon called “translocation,” the topic for this episode of the Defiant Health podcast. _______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

• Seven Reasons to NEVER Eat Wheat Again

  Those of you who follow my discussions that started with the Wheat Belly series of books already know that there is a long list of reasons why humans made an enormous blunder when we first resorted to the consumption of the seeds of grasses, meaning wheat and related grains. We know this from the anthropological record of human disease, we know this from modern science that has exposed the many problems that arise with their consumption from tooth decay to arthritis. But in my many conversations with people, I find that, because we are all bombarded with the opposite message from TV commercials, media reports, even doctors and dietitians, much of the rationale and science that tells us that wheat consumption is awful for health becomes diluted, or discounted, or ignored. My Wheat Belly arguments, for instance, have been dismissed as just another “gluten-free” message that has no bearing outside of celiac disease. Or that there are bad health consequences of banishing an entire category of food. Or that, if the U.S. Dietary Guidelines for Americans tell us that grains must be a part of the human diet, it must therefore be true. Of course, this is all not true: misinterpretations, misrepresentations, sometimes outright lies, all to prop up continued consumption of a class of “foods” that accelerate disease, aging, and should have no place in the diet of humans. So for this reason, I am going to be guilty of repeating myself and once again reiterating why the arguments against the inclusion of wheat and grains are overwhelming, the health impact of their consumption shockingly awful, and the health benefits of their abandonment huge and life-changing. _______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._______________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed
