When I was in the middle of my own decade-long health struggle, the first change I made was my diet which is usually where I see clients start. I removed gluten and dairy, and when that didn’t work, I went on a full AIP (autoimmune protocol) for years (there’s SO many reasons why that’s a bad idea!). While my diet changes absolutely helped reduce some of my symptoms, it never fully resolved anything. I still had many, many food sensitivities, major gut issues, fatigue, anxiety, and the list went on. At first I thought I needed to “try harder,” but no matter how strict I was, changing my diet was ultimately not the solution. It wasn’t until I looked past just food, and at the real reasons why I was continuing to have so many unresolved symptoms that I actually felt a major shift.
If you’ve already changed your diet and you’re still dealing with fatigue, pain, brain fog, or hormonal imbalances, this doesn’t mean you’re doing something wrong. It usually means you’re missing multiple issues beyond just changing what you eat.
Quick Summary
- Diet is a powerful tool for calming inflammation and supporting gut health, but it’s rarely the whole picture in autoimmunity.
- Hidden infections, environmental toxins (like mold), chronic stress, and hormone imbalances can all keep your immune system activated regardless of how clean you eat.
- Genetics only loads the gun but it’s environmental and physiological triggers that pull it.
- Functional lab testing helps identify the causes for immune system dysfunction, so you’re not guessing.
Why Food Feels Like It Should Be the Answer
I understand why diet gets so much attention. It’s the piece of the puzzle you can control, and we know it absolutely makes a difference when paired with additional functional testing, protocol, and lifestyle changes. You can’t see your gut lining or measure your body’s stress levels, but you can decide what goes on your plate. So when you’re searching for answers, diet is often the first and sometimes only recommendation you’re told to make. However, most people are told to eat a generic “anti-inflammatory” diet or they find the latest trendy diet on social media that claims to fix everything.
The problem with generic nutrition advice is that it does not take into account what your body specifically needs. While what you eat does influence inflammation, blood sugar stability, and gut health, you could be eating very health foods that are contributing to your symptoms. I’ve also seen people go straight to only testing for food sensitivity to figure this information out, but that still does not answer or solve the bigger problem that contributed to the autoimmunity and immune dysfunction. It’s simply once piece of the puzzle, and if you’re only changing diet (even with food sensitivity testing), you may initially feel better but eventually you’ll start to notice your symptoms creep back in.
What’s Actually Driving Your Immune System Dysfunction
Autoimmunity happens when your immune system loses the ability to tell the difference between your own tissue (“self”) and something it should be attacking like bacteria or pathogens (“non-self”). Diet can support the immune system, but it can’t fix every reason that system went off course in the first place, including the role inflammation plays in fueling autoimmune flares. Here’s what else is usually in the mix.
Your Genes Load the Gun, But They Don’t Pull the Trigger
Autoimmune conditions can run in families, but genetics do not tell the whole story. Just because you have the genetic propensity for an autoimmune condition, does not mean you’re guaranteed to get it. You can live your whole life with a strong disposition for an autoimmune condition, but never experience symptoms or a diagnosis. Twin studies are one of the clearest ways researchers notice this since identical twins share virtually all of the same genes. Yet when one identical twin develops an autoimmune condition, research shows the other twin only develops it about 25-50% of the time (1). This tells us that your environment and your physiology has to activate that genetic susceptibility. Diet can influence that environment, but again, it’s only one piece of it.
Hidden Infections Can Confuse Your Immune System
Chronic or reactivated infections are common and often-overlooked in autoimmunity. One example of this is Epstein-Barr virus (EBV). A study from Stanford Medicine, published in Nature, found that part of EBV closely resembles a protein found in the brain and spinal cord closely enough that the immune system can mistake one for the other and begin attacking the body’s own nerve cells (2). This process is known as molecular mimicry, and happens when a virus or bacteria has a structure so similar to your own tissue that your immune system can’t reliably tell the two apart. The virus or bacteria often “hides” in your cells or organs, but your immune system still knows it’s present and will start attacking the invader and your own cells at the same time. No amount of dietary change resolves an active infection your immune system is still fighting in the background.
Environmental Toxins & the Immune System
A 2021 scientific review out of Leipzig University found that mold and mycotoxins are of particular concern for people who already have a dysregulated immune system, since exposure can worsen chronic inflammation and autoimmune conditions (3). This is because mold and mycotoxins often create a huge cascade of inflammation and immune dysregulation, both of which contribute to autoimmunity. This piece of the puzzle is the one I commonly see with autoimmune issues, and it’s also the piece that no one wants to admit may be the problem. Other environmental toxins and toxicants that contribute to autoimmunity include heavy metals, radioactive elements, and everyday chemicals from plastics, pesticides, and personal care products. You can eat the cleanest diet in the world and still have a heavy toxic burden that keeps your immune system dysregulated.
Chronic Stress Affects Your Immune Response
People know they need to reduce stress, but are challenged to actually do it. Women who have autoimmunity often are in caregiver roles and place the care of others’ before themselves. They justify their stress levels because they need to help their loved ones, but they never take the time to help themselves. Multiple studies have found that up to 80% of people report unusually high emotional stress in the period before their autoimmune disease developed (4). Chronic stress activates your HPA axis (your hypothalamic-pituitary-adrenal axis which is your body’s stress-response system), dysregulates cortisol levels, and weakens your gut barrier. If your nervous system never gets the chance to come out of fight-or-flight, your immune system doesn’t get the chance to rebalance either, no matter how supportive your meals are. (If stress is a big piece of your puzzle, this is a great place to start.)
Hormone Shifts Add an Additional Consideration
Roughly 80% of people living with autoimmune disease are women, and researchers believe estrogen’s effects on the immune system are a major reason why (5). Estrogen can act on nearly every cell type in the immune system, and its fluctuation across your cycle, postpartum period, and into perimenopause is thought to help explain why so many of my clients notice their symptoms intensify during these hormonal transitions. These hormone-driven shifts in immune reactivity happen all on their own, separate from anything on your plate.
Why “Just Eat Clean” Isn’t a Plan
When changing diet is recommended as the only solution, it’s easy to start blaming yourself when you don’t see results. If you’re still struggling despite eating “clean” or an “anti-inflammatory” diet, this can lead to a negative mindset. People often think they’re not strict enough, not consistent enough, not trying hard enough, or even worse that changing their diet doesn’t matter at all. This is not the case. You are simply missing pieces of the entire picture that diet was never going to be able to fix on its own.
This is exactly why I start with targeted diet changes on day 1 of working with a client, so we know exactly which changes you need to make based on your functional lab testing. That’s the difference between guessing your way through diet changes, and eating in a way that’s built around your specific needs from the start.
My Approach Looks at the Whole Picture
In my practice, diet & nutrition is part of the foundations we support but never the entire plan. This is the basis of my root-cause philosophy, and here’s how I actually approach it with clients:
- Build the foundation. We start with the basics your body needs no matter what else is going on: nutrient-dense food, stable blood sugar, good digestion, and proper hydration.
- Uncover what your body is telling us. Functional lab testing shows us what’s really happening with gut imbalances, hidden infections, toxic burden, hormone patterns so we’re working from actual data & not guessing.
- Build your personalized plan. Once we know your specific drivers, we address them in the right order, at the right pace, so your body isn’t overwhelmed and nothing important gets missed.
This is the difference between managing symptoms indefinitely and actually getting your life back.
You Deserve Answers Beyond Your Food
If you’ve already done the hard work of cleaning up your diet and you’re still not feeling better, it’s not necessarily due to lack of effort. It’s a sign there’s more going on that deserves a closer look.
If you’re still guessing your way through this alone, please know you don’t have to. I’d love to help you figure out what’s actually driving your symptoms and build a plan around your real root causes and not just another diet change.
