Your Brain Has an Immune System – Free Webinar with Dr. Eric Zielinsky
If your thinking sometimes feels foggier than you would like, a familiar name slips your mind, or an afternoon slump makes concentration harder, it can be tempting to write those moments off as “just getting older.” This event offers another question to consider without assuming that any one symptom has a single cause.
Your brain and immune system are not separate worlds. The session looks at the brain’s resident immune cells and the ongoing conversation among the brain, gut, and immune system, giving you a clearer framework for understanding why researchers are paying attention to these connections.
Public health researcher Dr. Eric Zielinski will also explain trained immunity in plain language and walk through a 90-day study in which participants changed one factor and took the same lab test before and after the study period.
You’ll hear what that study found for a measure of brain age, how Dr. Zielinski interprets changes in immune markers, and where beta-glucan fits into the discussion. The live format also gives you an opportunity to bring your own questions to the Q&A.
Why Attend “Your Brain Has an Immune System: What a 90-Day Study Revealed About Brain Age and Trained Immunity”
Changes in focus, recall, mood, or mental energy can have many influences, so it helps to avoid reducing them to a single explanation. This training adds immune function to the conversation by examining the brain’s resident immune cells and the ways the brain, gut, and immune system are discussed together.
The 90-day study gives the session a concrete research question to work through. Dr. Zielinski will describe what happened when participants changed one factor, how the same lab test was used before and after, and what the study found for a measure of brain age without turning one study into a promise of personal results.
The event can also help you make sense of a term that is becoming more common in immune-health discussions: trained immunity. By hearing the study, the immune-marker pattern, and the brain-health questions explained in plain language, you can leave with better context for the live Q&A and for conversations with a qualified healthcare professional.
What You’ll Learn
In this session, you’ll start with the brain’s resident immune cells and the idea that brain health and immune health are connected, so you can follow the rest of the discussion without needing a technical background.
From there, Dr. Zielinski will connect the gut, immune system, and brain and explain what researchers mean by trained immunity, which means the study findings can be understood in a broader immune-health context rather than as an isolated number.
Along the way, you’ll hear how the 90-day study was structured, what happened to a measure of brain age, and why some immune markers moved in different directions, so the live Q&A can focus on the questions that matter most to you.
Here’s just a little bit of what you’ll learn:
- What the brain’s resident immune cells do and why Dr. Zielinski includes them in the brain-health conversation
- How the session connects the gut, immune system, and brain
- What researchers mean when they talk about trained immunity
- How the 90-day study used one change and the same lab test before and after
- What the study found for a measure of brain age
- Why Dr. Zielinski will discuss immune markers that moved up as well as down
- How poor sleep, stress, processed food, and environmental chemicals are discussed as part of the overall load
- How foggy thinking, slower recall, and mood changes fit into the event’s educational discussion
- Where beta-glucan fits into the study and Dr. Zielinski’s personal routine
- How to bring your own question into the live Q&A
Who This Is For
This live training may be useful if you have noticed occasional brain fog, slower recall, flat moods, or dips in mental energy and want broader educational context for the connection between brain and immune health. Those experiences can have many causes, and the event does not diagnose what is behind them.
You do not need to be a “science person” to follow the session. Dr. Zielinski’s role is to make the research understandable in plain language, so the event can suit beginners as well as health-conscious viewers who already know something about gut health, brain health, or immune support.
- You want a plain-language introduction to the brain’s resident immune cells
- You are curious about the gut-brain-immune connection
- You have heard the term trained immunity and want to understand the event’s perspective on it
- You want to hear how a 90-day study was structured and measured
- You are interested in the study’s brain-age measure and immune-marker findings
- You prefer health education that distinguishes study findings from personal guarantees
- You want the opportunity to ask Dr. Eric Zielinski a question live
About Dr. Eric Zielinski
Dr. Eric Zielinski is a public health researcher and Better Way Health educator. In this live training, he focuses on the relationship between immune function and brain health, including the brain’s resident immune cells, trained immunity, and findings from Better Way Health’s 90-day study.
His teaching style emphasizes making research easier to follow in plain English. He will walk through the gut-brain-immune connection, explain how he interprets changes in immune markers, and place the study’s brain-age measure in context rather than reducing the conversation to a single headline result.
Dr. Zielinski also plans to discuss the beta-glucan used in the study, including how he uses it himself, and he will take attendee questions live. The session is educational and is not individualized medical or supplement advice.
