FOR PRACTITONERS
LEARN IMMUNOLOGY BEHIND CHRONIC SYMPTOMS, INFLAMMATION, & COMPLEX CASES
MOST NUTRITION PROGRAMS TEACH WHAT TO RECOMMEND. IDN HELPS YOU UNDERSTAND WHY THE BODY IS INFLAMED, WHY SYMPTOMS PERSIST, AND HOW TO THINK THROUGH COMPLEX CASES WITH MORE CLARITY.
Functional nutrition practitioners are often taught to focus on gut healing, food sensitivity testing, supplements, detox support, and metabolic markers. These tools can help, but they are not always enough.
When a client is not improving, reacting to everything, struggling with autoimmunity, chronic inflammation, fatigue, hormone shifts, gut dysfunction, viral load, or unexplained symptoms, you need a deeper framework.
That framework is immunology.
At Heal From Food, Stacy Seslowsky, RD, LDN, MS teaches healthcare practitioners how to understand immune activation, inflammation, mitochondrial stress, gut-immune signaling, and clinical patterns so they can build more thoughtful, targeted, and effective nutrition strategies.
HOW I CAN HELP
The missing puzzle piece in many Functional Nutrition Cases Is Immune System Literacy
IDN simplifies complex immune concepts so you can understand what is happening beneath the symptoms. You will learn how the immune system responds to injury, infection, stress, food, gut dysbiosis, autoimmunity, and chronic inflammatory signals and how to translate that knowledge into nutrition, supplement, lifestyle, and testing decisions.

SERVICES FOR PROFESSIONALS
HOW I WORK WITH PRACTITIONERS
IDN Course
An 8-week professional training that teaches dietitians and nutritionists how to apply immunology to chronic inflammation, autoimmunity, gut dysfunction, metabolic health, hormones, and complex clinical cases.
In IDN, you will learn how to think through immune activation from the ground up — including innate and adaptive immunity, acute and chronic inflammation, antigen presentation, cytokines, T-cell polarization, immune responses to pathogens and food, autoimmunity, mitochondrial stress, and case-based clinical application.
The goal is not to turn you into an immunologist. The goal is to help you become a more precise, confident, and clinically thoughtful practitioner.
IDN Community Forum
For IDN graduates who want ongoing clinical discussion, continued learning, and practitioner community.
The monthly forum gives graduates a place to ask questions, discuss cases, review new research, and continue applying immunology-informed functional nutrition in real practice.​​
Precision Health Architect Series
This dynamic series of four masterclasses is designed to revolutionize how you approach complex health challenges, combining cutting-edge genomics, nutritional biochemistry and immunology with practical application. Our unique, integrative approach empowers practitioners to transform their practices and witness significant improvements in patient well-being.
Mentorship
For practitioners who want help applying functional nutrition and immunology concepts to real cases.
In mentorship, Stacy helps you think through patient cases, organize priorities, review food and supplement strategies, interpret available labs, identify when additional testing may or may not be useful, and troubleshoot when a patient is not tolerating the plan or not responding as expected.
