Reverse   My guest on today's podcast is a multi-time, incredibly popular repeat guest, and hosts one of the most popular alternative health website on the internet. He is my brilliant and controversial friend Dr. Joseph Mercola.      Dr. Mercola has been a guest on many previous podcast episodes.     Dr. Mercola just released a special report at , and he has some very interesting ideas in that free report that we explore and unpack in today's podcast. During our discussion, you'll discover: -Beginning the day with Vitamin D...5:15       -The physiological benefits of Vitamin D...7:15         -Vitamin D as a steroid hormone...10:40         -Why Vitamin D deficiency is a growing problem...14:35         -The impact of Vitamin D on the immune system...23:30         -How Vitamin D regulates the innate immune system...30:10       -The connection between Vitamin D and antimicrobial peptides (AMPs)...34:15         -How a Vitamin D deficiency increases the risk for acquiring COVID-19...36:25       -Proper dosing of Vitamin D to avoid toxicity...44:10       -Dr. Mercola's recommendations to stop COVID cold...51:50 -New, interesting and novel things currently captivating Dr. Mercola's interest...56:15 After publishing my recent giant fish oil article , I've been getting plenty of questions about fish oil lately, including: -Based on human clinical research, what are the actual proven benefits of fish oil? -What kind of dosages/types of fish oil were used in studies? -Are there concerns about rancidity/oxidation when taking fish oil? -What kind of amount and EPA/DHA ratio is ideal? -Are there people who shouldn't take fish oil? -Are there certain nutrients or supplements that should be taken with fish oil? -How can one test their omega fatty acid status? And much more. So I finally decided to get a couple of true, unbiased fish oil experts on my show. is my first guest. He is an internationally recognized expert on omega-3 fatty acids and how they can benefit patients with heart disease. He obtained his Ph.D. in Human Nutrition from the University of Minnesota and did post-doctoral fellowships in Clinical Nutrition and Lipid Metabolism with Dr. Bill Connor at the Oregon Health Sciences University. His interest in omega-3 fatty acids began with his postdoctoral work when he published his first study on the effects of salmon oil on serum lipids in humans (1980). Since that time he has been the recipient of five NIH grants for studies on the effects of omega-3 fatty acids (EPA and DHA) on human health. He has more than 300 publications relating to fatty acids, including omega-3s, in medical literature and was an author on two American Heart Association scientific statements on fatty acids: “, and “ both published in the journal Circulation. Dr. Harris is a Professor in the Department of Medicine in the Sanford School of Medicine at the University of South Dakota and the President and CEO of OmegaQuant. Dr. Harris's daughter, , PhD, RD is my second guest. Kristina received her PhD in Nutritional Sciences from Pennsylvania State University in 2013 and completed her training to become a Registered Dietitian in 2014. As a graduate student, she studied under Dr. Penny Kris-Etherton, an internationally-recognized expert in fats and nutrition. She worked as a postdoctoral fellow at the University of Colorado-Denver under Dr. John Peters in the area of worksite wellness before returning to the omega-3 field. Kristina joined the family business Analytics as a Research Associate in 2014, with a particular focus on omega-3s in maternal health, helping create the Prenatal DHA test and the Mother’s Milk DHA test. In 2020, she became Assistant Professor (non-tenure) in the Department of Internal Medicine at the University of South Dakota Sanford School of Medicine. (2020-2022). She lives in Sioux Falls, South Dakota with her husband, two kids, one old dog, and four grandparents. During this discussion, you'll discover: -The 2 sources of Omega-3 fatty acids...8:35 Plant derived fatty acid ALA, alpha linolenic acid( 18 carbons); an acid in the omega-3 family – not the same thing as the fish derived omega-3 Fish derived EPA (20 carbons) and DHA (22 carbons) Cannot get much of the good stuff from ALA (seeds and nuts) Algal oil from micro algae (single cell organism, not kelp) that make EPA/DHA naturally; at the base of the marine food chain Omega-3 fatty acids are made by plants, not fish Some companies grow these algae in big ponds, harvest the omega-3 fatty acids and put in capsules Vegan derived EPA/DHA products has exactly the same molecules as EPA/DHA derived from fish, but does not come from fish, it comes from algae Process is expensive Aquaculture industry is driving the demand for algal oil 70~80% of fish oil produced is fed back to the fish Other sources of fish oil are genetically modified land plants Canela seed oil; Australia is at the forefront to put genes into oil producing land plants, like soy beans -What makes essential fatty acids so essential...15:45 Cell membranes, made up of fatty acids, surround every cell in the body For structural aspect of the cell Provides starting products for different signaling pathways, affects how cells communicate internally and externally Membrane fluidity; more carbon and double bonds makes cell membranes more flexible and fluid Cell membranes are comprised of dietary fats The body can’t make the essential omega-6 fatty acids (linoleic) and omega-3 fatty acids(ALA and EPA/DHA); these comes from the diet Trans-fats are also dietary fats Other fats, like saturated fats and monounsaturated fats, are affected by metabolism -Omega-3 fatty acids being oxidized once it enters the body is a misconception...19:36 Oxidation has different meanings to a biochemist and a food scientist: Oxygen molecules are added to the fatty acids by enzymes in order to be activated Lipid peroxidation destroys, produces unwanted by-products; does not happen inside the body because of the different anti-oxidants that protect against this type of oxidation Article: The body has ways of cleaning up things it doesn’t want -Ratio of omega fatty-acids in the body and what the ratios should be...25:32 Good ratio of EPA to DHA is when eaten in fish EPA taken alone increases EPA and decreases DHA a little bit; increased omega-3 index - the measure of EPA/DHA in red blood cells (RBC) Pure DHA taken alone increases both EPA and DHA in RBC DHA is the predominant omega-3 fatty acid in membranes 85% DHA to 15% EPA in RBC In fish oil, total dose (EPA+DHA) is the important thing A study found the ideal optimum fatty acid levels (EPA+DHA) to be 8~12% index Ratio of omega-6 to omega-3 -Ethyl Ester and Triglyceride forms of Omega-3 fatty acids...33:20 Different ways Omega-3 fatty acids are processed and concentrated Ethyl ester is the first highly concentrated form; first to be concentrated into a capsule Triglycerides form is the more natural form (how it would be present in the fish) Most fish oil supplements in the U.S., if it does not say it is in triglyceride form, is an ethyl ester No standardized way to know if it is triglycerides or ethyl ester Biggest difference as far as bioavailability goes is if supplements are taken with meals Ethyl esters, if taken without a meal might not be absorbed at all; absorbed well if taken with a meal, preferably a meal that contains fats Triglycerides are not affected by that meal component as ethyl esters All pharmaceutical brands of fish oil are ethyl esters More EPA and DHA molecules in a 1 gram capsule if in ethyl ester form Distinction only came up around 15 years ago when ethyl ester form of fatty acids was seen as not well absorbed by the body when taken on an empty stomach Taking ethyl ester form supplements without food might not get the desired omega-3 index result -What genes convert ALA or plant-based oil into EPA/DHA...45:15 Genetic conditions that affect omega-3 fatty acid levels FADS genes produce the enzymes that convert ALA to EPA and DHA Enzymes also convert linoleic acid to arachidonic acid (polyunsaturated omega-6 fatty acid) Natural variations by populations in the kinds of mutations that are present in the FADS genes can affect levels, particularly of arachidonic acid Omega-3 EPA/DHA are not much affected by the FADS genes Major genetic effect driving omega-3 levels in the population is not known Is there a genetic effect on the absorption of omega-3 in the population? No study on why a certain population has a huge absorption response while in another population, there is hardly any response Nomenclature: Omega-3 ­– a fatty acid where the 1ˢᵗ double bond counting from the omega carbon is in the third position Omega-6 – a fatty acid where the 1ˢᵗ double bond counting from the omega carbon is in the sixth position Cannot be inter-converted Plants can convert omega-6’s into omega-3’s, animals cannot -Ratio of omega-6 to omega-3 fatty acids...52:17 “Ratio of omega-6 to omega-3” is imprecise – it’s not clear what type omega-6 or omega-3 is referred to; for example, there are 7 omega-6 fatty acids in the blood It also presumes that ALA and EPA/DHA have the same biologic activity or they have the same value when they do not The same is also true on the omega-6 side To say “total omega-6 to total omega-3 ratio” would also be confusing; it does not say what type fatty acids are there; it does not tell anything about it's effect on health - some fatty acids are beneficial and some are not You can have very high levels of omega-6 and omega-3 in your blood, or you can have very low levels, and yet have the same ratio It also presumes that all omega-6’s are bad and all omega-3’s are good, which is not true Omega-3 fatty acids being good is not questionable What’s questionable is the goodness or badness of omega-6’s; linoleic acid is not made in the body and has to be eaten Studies have shown that high levels of linoleic acid in the blood always predict lower incidence of heart disease and diabetes, and conversely Focus on the omega-3 index is that EPA/DHA are what is missing in our diets; there are plenty of omega-6’s -Link between Omega-6 and inflammation and chronic disease...1:00:18 High consumption of oxidized PUFAs , primarily found in vegetable oils which are high in omega-6 fatty acids Omega-6 fatty acid that gives rise to eicosanoids in the inflammatory pathway is Arachidonic acid, a synthetic product of linoleic acid Eicosanoids is associated with increased incidence of inflammation and chronic diseases like arthritis, cancer, etc. Synthesis of arachidonic acid is very regulated; tissue levels remain the same regardless the amount of linoleic acid consumed, to a point (it eventually runs out if linoleic acid consumption is stopped) Higher levels of linoleic acid in the blood means you are eating more of it, which comes from vegetable oil; the only way to get high levels in your blood is to eat more For heart disease and diabetes, higher levels of linoleic acid is good for the heart and metabolism; less people develop these diseases if they have high levels of linoleic acid The best way to decrease the ratio is to increase your omega-3 side; by increasing EPA/DHA, EPA replaces, to some extent, the arachidonic acid Having more long-chain omega-3 in the membranes lowers omega-6, correcting the proportion -Contaminants in fish oil, cleanliness, sourcing, concerns about packaging, shelf life, heat exposure during the manufacturing process...1:06:13 Article: Adding anti-oxidants makes a lot of sense Nitrogen blanketed environment during encapsulation Fish oil “gone rancid” does not necessarily mean the omega-3 fatty acids are gone, it just smells bad; the bad smell is caused by any of 6 molecules The best way to know the fish oil supplements are working for you is by testing -And much more!

He is the co-founder and chief innovation officer at and the co-founder and executive director of . In addition to his clinical psychiatry practice, Dr. Rabin is currently conducting research on the epigenetic regulation of trauma responses and recovery to elucidate the mechanism of psychedelic-assisted psychotherapy and the neurobiology of belief. He received his MD in medicine and PhD in neuroscience from Albany Medical College and specialized in psychiatry at the University of Pittsburgh Medical Center. He has been married to Kathryn Fantauzzi, CEO and co-founder of , since 2016. Together they live in Monterey, California.         Joining Dr. Rabin on this show is Dr. Joseph Maroon, Clinical Professor and Vice Chairman and Heindl Scholar in Neuroscience at Department of Neurosurgery at University of Pittsburgh. In addition to being a world-renowned "burnout expert", and completing eight Ironman triathlon events since turning 50, he is involved in development of minimally invasive surgical procedures for diseases of the brain, orbit and spine, the prevention and treatment of traumatic injuries to the central nervous system, innovative approaches to pituitary and other brain tumors, complimentary and alternative medicine approaches to inflammatory diseases associated with aging, the prevention and treatment of sports related injuries and is co-developer of ImPACT, a neurocognitive test that is now the standard of care for concussion management in the NFL, NHL, MLB, NASCAR and over 12,000 high schools and colleges in the United States. It is the only FDA approved test for concussion evaluation with 23 million athletes base line tested to date. Dr. Maroon is also the neurosurgical consultant for the Pittsburgh Steelers for 30 years and first neurosurgeon directly appointed in the NFL.         Over the last several years, Dr. Rabin has been amassing a dream team, which has become , a 501c3 nonprofit coalition led by some of the world’s leading experts across many diverse fields of AI, nutrition, psychedelics, and clinical medicine that supports evidence-based strategies for harm-reduction in medicine and public health. He believes that the future of healthcare in the 21st century is going to change substantially as a result of the current pandemic and, it is pretty clear that we are woefully underprepared for this as a healthcare system. The most significant change will be that most forms of non-urgent medical care will be delivered directly to patients/clients in their homes via telemedicine.       He is already seeing this shift in mental health to include ketamine-assisted tele-therapy and the integration of wearable technologies. As such, the future of healthcare is looking more and more digital and psychedelic with each passing day.         This podcast will focus on AI, psychedelics, and the convergence of Eastern and Western medical disciplines in the current and post-COVID times.

My guest on today's show is Adam Wenguer, who has grown to be a friend of mine after we met training at a gym in Miami, Florida. Adam grew up in Miami, in a Cuban Jewish household. He started Martial Arts at a young age and continues extensive Jiu Jitsu practice as a brown belt as well as training in Boxing and Muay Thai kickboxing. Adam attended the University of Florida in 2006.         After suffering a spine and leg injury in College, Adam was treated with pharmaceutical opioids which led to an intense but all too common addiction. On his path to recovery he became immersed in Zen Buddhism, Health & Wellness, and began his life long path into Spirituality. This eventually led Adam to graduate with a degree in Applied Physiology & Kinesiology as he sought to bring greater physical healing to others, as he had done for himself.         As a Strength/Conditioning and Health Coach at a well known 5 star wellness resort, he worked with wide array of professional athletes, company executives and individuals seeking optimal health. Many of his client were suffering from the same ailments: including sleep issues, anxiety, inflammatory disorders as well as a general emotional and spiritual disconnect. This led Adam to wanting to take a more holistic approach towards educating and treating his clients with the use of natural compounds such as CBD. In 2017, Adam founded Element Health which is now one of the leading suppliers of the highest quality Full Spectrum CBD products in the world.         Adam spends a majority of his time with his wife Kristen and their 3 dogs in their beach community of Surfside, FL. In his free time he continues to train and compete in Martial Arts. He is also heavily involved in the study of plant medicine and the shamanic approach to healing.

I recently read "". From a leading neurologist, neuroscientist and practitioner of Ayurvedic medicine, comes a rigorous scientific investigation of the healing power of sound, showing readers how they can use it to improve their mental and physical wellbeing.       Why does a baby’s cry instantaneously flood a mother’s body with a myriad of stress hormones? How can a song on the radio stir up powerful emotions, from joy to anger, regret to desire? Why does sound itself evoke such primal and deeply felt emotions?       A vibration that travels through air, water and solids, sound is produced by all matter, and is a fundamental part of every species’ survival. But there is a hidden power within sound that has only just begun to be investigated. Sound Medicinetakes readers on a journey through the structure of the mouth, ears, and brain to understand how sound is translated from acoustic vibrations into meaningful neurological impulses. Renowned neurologist and Ayurvedic expert - and of course, my guest on today's podcast - Dr. Kulreet Chaudhary explains how different types of sound impact the human body and brain uniquely, and explores the physiological effects of sound vibration, from altering mood to healing disease.         Blending ancient wisdom with modern science, Dr. Chaudhary traces the history of sound therapy and the use of specific mantras from previously unknown texts—traced back to the Siddhas, a group of enlightened yogis who created a healing tradition that served as the precursor to Ayurvedic medicine—to explain the therapeutic application of sounds for a wide range of conditions. During this show, you'll get practical, step-by-step lessons for using music and mantras, whether you’re a beginner or searching for a more advanced practice, to improve your health in body, mind, and spirit.       Dr. Kulreet Chaudhary’s combined expertise in both modern neurology and the ancient science of health known as Ayurveda has uniquely positioned her as an expert able to pull from the broadest possible base to treat her clients. She is passionate about raising awareness for the need of a paradigm shift in contemporary medicine that focuses on patient empowerment and a health-based (rather than disease-based) medical system. Dr. Chaudhary is a regular guest on the Dr. Oz show, where her teachings about Ayurvedic medicine have been applauded by a national audience.       Dr. Chaudhary was the Director of Wellspring Health in Scripps Memorial Hospital for ten years, and remains a pioneer in the field of Integrative Medicine. Dr. Chaudhary has successfully developed a powerful system to manage chronic neurological disorders such as multiple sclerosis, Parkinson’s disease and migraine headaches, by incorporating fundamental changes in diet, behavior, and stress, in addition to the standard allopathic approach to these issues. This program has been so successful that many patients now use it not just for neurological issues but also for a wider range of health concerns, including weight issues and chronic disease.       Dr. Chaudhary is the author of The Prime and Sound Medicine and has appeared as a medical expert on numerous programs including The Dr. Oz Show and Home & Family. She is also a neuroscientist and has participated in over twenty clinical research studies in the areas of multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, ALS, and diabetic peripheral neuropathy. Her research includes groundbreaking work in stem cell therapies for diabetic peripheral neuropathy and drug development for the treatment of ALS.

I get fresh air whenever possible, and I workout regularly. I've been on point with nutrition. I'm willing to invest in the sauna at some point, but in the meantime, I'd like to know the best way to detoxify from these daily toxins, other than finding a new career.           Blood flow during sauna sessions...1:06:50 Sheldon asks: I just recently listened to your podcast with bodybuilder Milos Sarcev. He mentioned that he takes his essential amino acids, creatine dextrose, pre and during workout to gain muscle mass because of the increased blood flow to the muscles during a workout. My question is, do you get the same benefit by doing the same thing, pre and during a sauna sessions with the increased blood flow?       My friend Ron Penna recently emailed me about a guy named Brad Marshall who...         "...has a fascinating take on why we get fat called the ROS (Reactive Oxygen Species) Theory of Obesity and how ROS signaling as a result of eating saturated fats is critical for satiety. Provocative stuff and the more I read the more I’m pretty sure he is onto something. Joel Greene thinks Brad is crazy on this point but I have a feeling he will end up being right on most if not all of it. You can read more here: "         Essentially, our entire meat supply (pork and chicken especially) is much higher in polyunsaturated fats than they should be and the only real way to change it is to change what we feed them. .  He also has been working on . It has to be wrong but he makes VERY interesting arguments about it."         Naturally, I just had to get this guy on the show. Brad Marshall is the author of the Blog and the creator of .  Mildly obsessed with food and its history, his work focuses on trying to place current ideas about diet, including keto and carnivore diets into the framework of traditional Dietary patterns.  For instance, the French diet before 1970 combined flour, sugar, butter and wine and the population was lean.         Brad wrote which posits that ROS generation in the mitochondria of fat cells could provide the mechanism that explains why a traditional chinese peasant diet - low fat with 85% of calories from starch; a French diet combining butter, wine and flour and a modern keto diet could all be expected to produce leanness but combining flour with polyunsaturated fats is a recipe for obesity.  The core idea comes from the Protons thread of Peter Dobromylskyj’s blog .  Brad tested this hypothesis with his dietary experiment The Croissant Diet.         Brad is also the founder of , which is dedicated to producing pork and poultry products that are low in Linoleic acid, the n6 polyunsaturated fat (PUFA) whose intake has seen a dramatic worldwide increase in the last century.  Animals cannot make PUFA and so we can create pork and chicken that is nearly free of them.  You are what your animals eat.       Brad has a genetics degree from Cornell, a certificate from The French Culinary Institute, has studied cancer at Memorial Sloan-Kettering Cancer center and worked as a programmer for the Berkeley Drosophila Genome Project.  He spent the last 15 years raising rotationally grazed pastured pork on his farm in upstate New York while running a butcher shop, local food restaurant and USDA inspected meat processing facility.

Can those fancy vibration platforms at your health club or gym really help you burn fat or lose weight, and is there any research behind that? Is there any significant hormonal response to whole body vibration (WBV)? What is the effect of vibration training on cardiovascular fitness, and how would it be used for that? Any effect on lymph fluid or immune health, similar to a trampoline/rebounder? How about for muscle recovery or delayed onset muscle soreness (DOMS)?  How does one actually use a vibration platform the right way? Can you stack WBV with other so-called "biohacking" modalities, such as photobiomodulation, EWOT, isometric training, etc?         Jason M.

is a massive book that I just finished (and briefly alluded to in my post ).         This highly controversial book will explain what really makes you ill and why everything you thought you knew about disease is wrong, based on Voltaire's quote that: "Doctors are men who prescribe medicines of which they know little, to cure diseases of which they know less, in human beings of whom they know nothing." The book reminds me of my recent interview .         The authors argue that the conventional approach adopted by most healthcare systems entails the use of ‘medicine’ to treat human disease. The idea, encapsulated by the above quote attributed to Voltaire, the nom de plume of François-Marie Arouet (1694-1778), will no doubt be regarded by most people as inapplicable to 21st century healthcare, especially the system known as modern medicine. The reason that people would consider this idea to no longer be relevant is likely to be based on the assumption that ‘medical science’ has made significant advances since the 18th century and that 21st century doctors therefore possess a thorough, if not quite complete, knowledge of medicines, diseases and the human body. Unfortunately, however, this would be a mistaken assumption; as this book will demonstrate.         Dawn Lester and David Parker are my guests on today's show, and they are the authors of . They have backgrounds in the fields of Accountancy and Electrical Engineering, respectively. These fields both require an aptitude for logic, which proved extremely useful for their investigation that has involved more than ten years continuous research to find answers to the question: what really makes people ill?         A popular saying, which is often attributed to Albert Einstein, claims that problems cannot be solved by using the same way of thinking that created them. The concept underlying this saying can be extrapolated to indicate that a problem can often be better understood by people outside of the discipline in which it occurs because they are not bound by any dogma or biases inherent within that discipline. The authors’ investigation of why people become ill was conducted from a different perspective from that of the medical establishment; it was therefore free from the dogma and biases inherent within ‘medical science’. This unbiased and logical approach enabled them to follow the evidence with open minds and led them to discover the flaws within the information about illness and disease that is promulgated by the medical establishment.         The results of their investigation are revealed within their book, and we explore those results on today's show.       During this discussion, you'll discover: -Why an accountant and engineer decided to write a book about health and disease...7:03         -Why David and Dawn's non-medical backgrounds were an asset to their research...14:15         -Why AIDS is rampant in Africa without drugs and antibiotics that cause it...21:10         -What we can learn from the 1918 Spanish Flu pandemic today...35:30         -The dangers of chlorine...46:00         -Giant rocks in space related to shifts in world health...49:30         -What causes disease (if it's not a virus)...57:05         -How David and Dawn have altered their diets since writing their book...1:01:00       -How to naturally battle health issues in our internal and external environments...1:05:30       -David's top health tips...1:11:45

This podcast has changed my life. Applying the ancestral practices of better living through fasting, prayer, meditation, gratitude, conscious and natural diet, movement, breathing, and cold therapy and the science backed research behind all these practices I can anecdotally confirm how powerful and life changing these practices are when incorporated in your lifestyle. I feel incredibly full of life and extremely grateful to have found out about this podcast and for Ben sharing his knowledge and skill in his research and interviewing his guest to create an incredibly knowledgeable podcast to the public.

Thank you for this episode. I'm a deep believer in nose breathing👃👃 as medicine and been meticulously monitoring my kids as babies for mouth breathing... Nose breathing is my way to breath and i can't do mouth breathing... It makes me sick. i am just discoving all kinds of pranayamas and getting slightly obsessive with breathing techniques.So thanks for the insights and more inspiration!!!
