In Good Health

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 lig...

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 i...

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 neu...

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 c...

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...

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...

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 unde...

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 Seslow...

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 oxida...

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?

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 u...
