The Immune System Gone Rogue: A Simple Explanation
A simple look at autoimmune disease, inflammation, and the factors that influence immune health.
When I was diagnosed with celiac disease, I finally had an explanation for why my body had been struggling for so long.
Like many people facing an autoimmune diagnosis, I felt relieved to have answers but overwhelmed trying to understand what it all meant. One of the biggest misconceptions about autoimmune disease is that the body is simply "attacking itself."
The reality is a little more complicated. Your immune system is designed to protect you, but in autoimmune conditions it becomes confused, mistakenly identifying healthy tissues as a threat.
Why is the immune system struggling in the first place?
Food-Related Contributors to Autoimmune Inflammation:
Ultra-processed foods found most prevalent in the United States over any other nation:
Excess added sugars
Refined carbohydrates
Industrial seed oils (highly processed vegetable oils)
Artificial food dyes and colorings
Artificial sweeteners
Preservatives and food additives
Emulsifiers (found in many packaged foods)
Gluten (for susceptible individuals)
Excess alcohol
Pesticide residues
Highly processed meats
Trans fats
Low fiber intake
Nutrient-poor, calorie-dense foods
When you get a diagnosis, it can feel like, “Here's your diagnosis. Here's your medication. We'll monitor you and see you back in a few months."
While medications can be essential and life-changing, many patients are left wondering what they can do day-to-day. That's often where nutrition, stress management, sleep, movement, gut health, and other lifestyle factors become part of the conversation.
Start Here: The Biggest Offenders to Reduce Inflammation
When working to lower autoimmune symptoms, it helps to start by removing the most inflammatory and disruptive foods first:
Alcohol – Does increase gut permeability, disrupt sleep, burden the liver, and amplify inflammation.
Industrial seed oils (corn, soybean, canola, sunflower) – Highly processed fats promote inflammatory pathways— even just in your daily coffee creamer!
Trans fats / ultra-processed fats – Found in many packaged and fried foods; strongly linked to systemic inflammation.
Gluten (for sensitive individuals or autoimmune conditions like celiac) – Can trigger immune activation and gut inflammation in susceptible people.
Then Focus On Adding Support:
Increase fiber from real foods – Vegetables, berries, legumes, chia/flax, and whole foods help feed beneficial gut bacteria, support detox pathways, stabilize blood sugar, and promote regular elimination.
Women need to eat 22-30 grams of fiber EVERY DAY
Men need to eat 30-38 grams of fiber EVERY DAY
Fiber isn’t sexy or flashy in the way that weight loss shots or other “magic” pills are. It should be!
Fiber is crucial for immune health
Feeds good gut bacteria – Fiber acts as fuel for beneficial microbes that help regulate immune function.
Supports the gut barrier – A healthy microbiome helps maintain the lining of the gut, where a large part of the immune system lives.
Reduces inflammation – Gut bacteria break down fiber into short-chain fatty acids that help calm inflammatory signals.
Helps clear waste – Fiber supports regular elimination, reducing recirculation of waste products in the body.
Balances blood sugar – Stable blood sugar helps prevent immune stress and inflammatory spikes.
Fiber helps keep the gut ecosystem balanced—and a balanced gut is one of the most important foundations of a regulated immune system.
When you are dealing with autoimmune symptoms that keep showing up, sometimes you just need a clear starting point. A custom session helps narrow down your biggest triggers and what to actually focus on first, so you’re not guessing your way through it.
