Today, I am honored to connect with Dr. Dominik Nischwitz, a German dentist, pioneer of biological functional dentistry and ceramic implantology, founder of DNA Aesthetics, and the Vice President of the International Society for Metal-Free Implantology. He's also an author with a particular focus on how optimal health starts in the mouth. In our discussion, Dr. Nischwitz explains why the oral microbiome is, in fact, the upper gut. We explore the impact of oral dysbiosis, hormonal changes in oral health, concerns about root canals, cavitations, and old wisdom tooth sites. We clarify that mercury amalgams are not benign and are known neurotoxins, and explain why big-mouth overhauls must be carefully planned. We also discuss the debate of fluoride versus hydroxyapatite, cosmetic dentistry concerns, and more. This is another invaluable conversation that you will likely want to listen to several times. IN THIS EPISODE, YOU WILL LEARN: Dr. Nischwitz explains the oral microbiome What is dysbiosis? How changes in estrogen and nitric oxide production affect the gums and oral tissues Dr. Nischwitz explains why he believes that conventional dentistry is outdated, and highlights the benefits of biodentistry Why so many people fear dentists The risks associated with root canals How cavitations can become infected and lead to chronic inflammation and other health issues Why mercury in dental fillings is so dangerous The importance of having mercury fillings removed safely by a certified biological dentist Why is hydroxyapatite safer than fluoride?

Today, I have the honor of connecting with Dr. Robynne Chutkan, one of the most recognizable gastroenterologists in the United States. She is also the author of Anti-Viral Gut, one of the books I enjoyed reading most in 2022! Knowledge of the microbiome dates back to the 1600s when Anthony van Leeuwenhoek observed bacteria in his dental plaque through a microscope. However, it has taken us several centuries to understand the interdependence and beneficial nature of those bacteria. The terms "microbiome" and "microbiota" are often used interchangeably. They refer to the organisms and genes that live in and on our bodies, predominantly in the GI tract. Those organisms include bacteria, viruses, protozoa, fungi, parasites, and archaea, which, despite their microscopic size, collectively weigh about 4 to 5 pounds.  Today, Dr. Chutkan and I dive deep into the physiology of the microbiome and discuss how that interplays with immunology. We discuss the benefits of hydrochloric acid, the impact of proton pump inhibitors and other medications on gut microbiome health, and the role of dysbiosis and the Estrobolome. We get into how the pharmaceutical industry has influenced both medical practice and the outlook of healthcare providers, and we talk about the impact of sleep, exercise, stress, and alcohol on the gut. Dr. Chutkan also shares top tips from her anti-viral diet book for supporting the gut. (One of her tips is to consume 30 plant types per week for a healthier gut microbiome.)  This show has been one of my favorite podcasts that I have recorded in the last year. I hope you enjoy listening to it! IN THIS EPISODE YOU WILL LEARN: What is the microbiome, and why is it important? Why do we need to understand the interrelationship between the oral microbiome, the gut microbiome, and the vaginal microbiome? The importance of stomach acid. How do proton pump inhibitors affect gut health? The three big things that interfere with digestion. How pharmaceutical companies have taken over medical education. The role of statins in women. Importance of the Estrobolome test. Three different types of estrogens in the body. Why exercise is an important contributor to gut health. The net impact of low-quality sleep on immune function. Dr. Chutkan shares her top tips for a healthy gut microbiome.

I am thrilled to connect with Dr. Lindsey Berkson today. The audacious and tenacious Dr. Berkson is a distinguished hormone scholar from the highly praised Center for Bioenvironmental Research at Tulane. She is the author of 21 books, and her impact on medical literature continues to grow. With her thoughtful manner and infectious enthusiasm for learning, she educates women about their bodies and health. Our discussion today highlights the importance of supporting the hippocampus and doing targeted cardiovascular exercise. We explore hormone replacement therapy, the timing hypothesis, and why oxytocin is more than just a bonding hormone. We cover endocrine-disrupting chemicals, detoxification, gut health, inflammation, and ways to support immunity, and we examine how oxytocin influences digestion, gut motility, and gut-brain access. We also explain how oxytocin protects our stem cells, prevents gut trauma after colonoscopies, reduces gut inflammation, and supports healthy transit time. Dr. Berkson’s new book, The Oxytocin Medicine, is truly an incredible resource and one I will reference often. It is most inspiring! IN THIS EPISODE, YOU WILL LEARN: How a shrinking hippocampus alters women’s identity and resilience The value of cardio-respiratory fitness and pushing limits for driving resilience How conservative hormone dosing may fail to protect women’s health in perimenopause and beyond Women’s Health Initiative messaging created a widespread fear of estrogen. Why Dr. Berkson challenges the timing hypothesis  The difference between synthetic progestins and naturally made progesterone Oxytocin and how it functions as a system-wide hormone Importance of detoxification during the perimenopause to menopause transition  Consistent patterns are common among women who age with physical and cognitive resilience.
