About In Good Health

Stacy Seslowsky, RD, LDN, MS explores the intricate dynamics between the immune system, cellular signaling, and mitochondrial function. Each episode examines how unresolved immune responses drive chronic inflammation, metabolic dysfunction, and tissue injury. Integrating concepts from immunology, neuroendocrinology, and systems biology, this podcast aims to deepen understanding of how immune, nervous, and endocrine pathways intersect to influence health, disease progression, and the potential for recovery and repair across the healthspan.

   #11 The Truth About Cortisol, Inflammation & Blood Sugar

   Cortisol gets blamed for everything from weight gain to burnout, but the real story is far more interesting. In this episode, we break down why cortisol is actually a metabolic powerhouse and an anti-inflammatory ally, not just a stress hormone to suppress. You'll learn how to spot chronic cortisol dysregulation directly on a CBC report using the neutrophil to lymphocyte ratio, why morning light exposure might be the simplest tool in your clinical toolkit, and the surprising connection between serotonin and your patient's ability to get out of bed feeling alert. If you've ever told a patient to just lower their cortisol, this episode will change how you think about that advice completely.

   #10 Nervous System Dysregulation: The Root of Inflammation & Hormone Imbalance?

   In this episode, Stacy explains the connection between the immune system, nervous system, and endocrine system through the lens of psychoneuroimmunology. You’ll learn how chronic stress impacts cortisol signaling, sympathetic activation, vagal tone, inflammation, histamine symptoms, hormones, and CBC patterns like NLR and LMR. If you work with clients dealing with chronic inflammation, histamine intolerance, hormone symptoms, recurring infections, or autoimmune tendencies, this episode gives you a clearer framework for connecting stress physiology to immune function.

   #9 Histamine Overload and Mast Cells: The Root of Allergy & Congestion

   Why do some patients seem to react to everything? In this episode of In Good Health, I break down the immunology behind histamine overload, mast cell reactivity, chronic congestion, hives, flushing, gut permeability, and why these symptoms are often more connected than they appear. We’ll also cover how to use the CBC more strategically by looking at eosinophils, basophils, and key ratios like neutrophil-to-lymphocyte and lymphocyte-to-monocyte to guide root-cause thinking and next steps.

   #8 Innate Immune System Explained (Using Your Bloodwork)

   In this episode of In Good Health, we break down the innate immune system through the lens of a complete blood count (CBC), one of the most underutilized clinical tools in practice. You’ll learn how to interpret key immune cells including neutrophils, monocytes, eosinophils, basophils, and more, not just individually, but as patterns that reveal what the immune system is actually doing. We also connect immune activity to: Chronic stress and cortisol Oxidative stress and mitochondrial dysfunction Allergies, histamine, and hypersensitivity Autoimmunity (including early Th17 connections) Cancer and viral surveillance via natural killer cells This episode is especially helpful for practitioners, students, and curious learners who want to better understand CBC patterns, immune balance, and how chronic inflammation can develop from upstream cellular dysfunction. ⁠Click here to Access the CBC Reference Guide (subscrsubscribepage.io/CBCreferenceguideibepage.io/CBCreferenceguide)⁠ Stacy Seslowsky, RD, LDN, MS is now accepting new patients.

   #7 What Your CBC Reveals About Inflammation and Immune Balance

   In this episode, I explain how inflammation progresses after NF-kappa B signaling increases inflammatory cytokines like IL-6, TNF-alpha, and IL-1 beta. I break down the differences between the innate and adaptive immune system. You will learn how cells like neutrophils, monocytes, eosinophils, basophils, macrophages, dendritic cells act as the first responders, and how antigen presentation bridges into the adaptive immune response, and how immune memory is formed.

   #6 Heart Disease Starts With Inflammation (Not Cholesterol)

   Heart disease may not begin with cholesterol, but with dysfunction at the cellular level. In this episode, we explore how mitochondrial dysfunction drives oxidative stress, immune activation, and the earliest stages of plaque formation in the arterial wall. Understanding this sequence shifts our focus from symptom management to identifying and addressing root cause. Stacy Seslowsky, RD, LDN, MS is now accepting new patients.

   #5 When Bloodwork Looks Normal, But Symptoms Are Not

   Mitochondrial dysfunction is a key driver of fatigue, brain fog, and chronic symptoms even when blood work appears normal. In this episode, we explore the root causes of mitochondrial dysfunction, including nutrient deficiencies, low oxygen, toxins, chronic immune activation, and lifestyle stress. Learn how these factors contribute to inflammation at the cellular level and how identifying the underlying cause can help restore optimal health.

   #4 What Does Mitochondrial Dysfunction Feel Like?

   By identifying all the various pathways that take place in the mitochondria, we can better understand the signs and symptoms a person might experience if they had mitochondrial dysfunction within the specific tissues and organs wherein the mitochondria exists. As practitioners, we can assess and address this cellular dysfunction before chronic imbalance leads to a diagnosable disease. Stacy Seslowsky, RD, LDN, MS is now accepting new patients.

   #3 Inflammation Can Stem From The Mitochondria

   In this episode of In Good Health, Stacy Seslowsky, RD, LDN, MS explores how inflammation and immune activation can begin in the mitochondria. When the electron transport chain releases reactive oxygen species (ROS), it can activate key proteins and transcription factors that signal the immune system. While low levels of ROS are essential for cellular health, chronic overproduction leads to oxidative stress and immune dysregulation. By identifying early signs of mitochondrial dysfunction, practitioners can restore balance, reduce inflammation, and support optimal mitochondrial and immune system health. Stay tuned for a series of episodes on mitochondrial health as we further explore relevant clinical applications. Stacy Seslowsky, RD, LDN, MS is now accepting new patients.

    #2 What Could Go Wrong With Anti-Inflammatory Strategies

    Stacy Seslowsky, RD, LDN, MS describes roles of the immune system that go beyond fighting pathogens. There may be unwanted consequences of diets and supplements solely focused on reducing inflammation. What if inflammation is reduced inappropriately?

    #1 Inflammation Accurately Defined; What The Body Is Trying To Say?

    Inflammation isn’t the enemy, it’s communication. In this episode, we explore how inflammation is your immune system’s language for signaling stress, imbalance, and repair. Learn how to interpret what your body is trying to say through immune activation, rather than just trying to silence the symptoms. Perfect for dietitians, nutritionists, and functional or integrative practitioners who want to understand the why behind chronic inflammation and approach healing from an immunology-informed perspective.
