Living with an autoimmune condition can often feel like your body is working against you—but there is hope. At Dr. Linette Williamson’s integrative practice, we help patients in Poway and surrounding San Diego County take a proactive and personalized approach to autoimmune health, beginning with something foundational: your diet.
What Is an Autoimmune Disease?
In simple terms, an autoimmune disease occurs when your immune system—designed to protect you—mistakenly attacks your body’s own healthy tissues. It’s like a case of mistaken identity where the immune system can no longer distinguish between harmful invaders and your body’s organs, joints, or glands.
This internal conflict can lead to a wide range of symptoms including chronic inflammation, fatigue, digestive discomfort, joint pain, brain fog, and skin issues. And because autoimmune diseases affect each person differently, they’re often difficult to diagnose and manage using conventional medicine alone.
Common Autoimmune Conditions We See
At our clinic, Dr. Linette has over 15 years of experience helping patients with a wide spectrum of autoimmune conditions, including:
- Rheumatoid Arthritis – Causes joint pain, swelling, and stiffness
- Hashimoto’s Thyroiditis – Affects the thyroid gland and metabolism
- Lupus (SLE) – Can involve the skin, joints, kidneys, and more
- Multiple Sclerosis (MS) – Impacts the nervous system and mobility
- Psoriasis and Psoriatic Arthritis – Skin and joint inflammation
- Inflammatory Bowel Diseases (Crohn’s, Ulcerative Colitis) – Chronic digestive inflammation
While each autoimmune disorder is unique, they all share a common thread: chronic immune dysregulation and inflammation that can be supported through functional, holistic strategies—starting with the foods we eat every day.
Why Diet Is a Foundational Pillar in Autoimmune Care
Food can either be a trigger or a tool in your autoimmune healing journey. Certain ingredients—like refined sugar, gluten, processed foods, and industrial seed oils—are known to increase inflammation and irritate the gut lining, which may worsen autoimmune flares.
On the other hand, an anti-inflammatory, nutrient-dense diet can help:
- Support gut health and reduce intestinal permeability (leaky gut)
- Regulate immune function and decrease flare-ups
- Provide vital nutrients needed for cellular repair and energy
- Improve overall quality of life by addressing fatigue, pain, and brain fog
At Dr. Linette’s integrative clinic, we emphasize personalized nutrition plans that are tailored to each patient’s immune system, sensitivities, and lab markers—rather than one-size-fits-all diet fads.
Autoimmune Trends in Poway & Greater San Diego County
We’ve seen a steady rise in autoimmune-related symptoms among patients in Poway, Rancho Bernardo, Escondido, and other nearby communities. Whether due to increased environmental toxins, chronic stress, poor gut health, or genetic predisposition, more individuals—especially women between ages 30–60—are seeking holistic alternatives to manage their autoimmune conditions.
Patients are often frustrated by being told their labs are “normal” or being placed on immunosuppressive drugs without addressing the root cause. That’s why our integrative model is so impactful—it goes deeper to identify nutritional, hormonal, digestive, and environmental triggers that contribute to autoimmune flare-ups.
The Role of Food in Autoimmune Health
The Immune System & Gut Connection
Did you know that nearly 70% of your immune system is housed in your gut?
The gut is more than just a digestive organ—it’s a command center for immune regulation. Lining the gut wall are immune cells that monitor what comes in through food and environment, acting as gatekeepers to protect the body. When this system is healthy, your immune response is well-balanced. But when the gut is compromised, immune function can go haywire—and that’s often when autoimmune symptoms begin to surface.
What Is Leaky Gut, and Why Does It Matter?
One of the most common gut issues linked to autoimmune diseases is leaky gut syndrome (also known as increased intestinal permeability).
In a healthy gut, the intestinal lining acts like a finely woven net, allowing nutrients through while keeping out larger molecules like toxins, undigested food particles, and harmful bacteria.
However, factors like poor diet, chronic stress, infections, and medications (like NSAIDs and antibiotics) can cause that lining to become damaged or "leaky." When that happens, unwanted substances enter the bloodstream, triggering an immune response. Over time, this chronic immune activation can lead to systemic inflammation and autoimmune flare-ups.
At Dr. Linette's clinic, we specialize in identifying and treating leaky gut through advanced diagnostics, targeted nutrition, and gut-repairing therapies.
Why Identifying Individual Food Sensitivities Is Crucial
Every person’s immune system is unique, which means autoimmune triggers vary widely from one patient to another. That’s why a blanket diet recommendation isn’t enough.
At our Poway-area clinic, Dr. Linette takes the guesswork out of the process by using:
- Comprehensive food sensitivity testing
- Stool and microbiome analysis
- Personalized elimination and reintroduction plans
This approach helps uncover hidden sensitivities that may not show up on standard allergy tests but are still contributing to inflammation and autoimmunity.
Patients are often surprised to discover that foods they considered “healthy”—like eggs, almonds, or tomatoes—might be aggravating their symptoms. Once these triggers are removed and the gut begins to heal, many experience significant improvements in energy, mental clarity, digestion, and pain levels.
Top Autoimmune Diet Tips From Dr. Linette Williamson
Eliminate Common Inflammatory Foods
Many autoimmune symptoms are rooted in hidden food triggers that increase gut permeability and activate immune responses. The first step is to remove the most common offenders:
- Gluten (especially from wheat, barley, rye)
- Dairy (milk, cheese, yogurt)
- Refined sugars
- Corn and soy
- Nightshade vegetables (like tomatoes, peppers, eggplants – depending on your condition)
Try a short-term elimination diet (typically 3–4 weeks) followed by a systematic reintroduction to identify specific sensitivities. Dr. Linette provides testing and support throughout this process to ensure it's safe and effective.
Focus on Gut-Healing Nutrients
A healthy gut lining is essential for immune balance. Healing the gut reduces inflammation, improves nutrient absorption, and helps prevent future autoimmune flares.
Incorporate:
- Bone broth – rich in collagen and amino acids
- Fermented foods like sauerkraut, kimchi, and coconut yogurt for probiotics
- Prebiotic fiber from foods like asparagus, garlic, and green bananas to feed good bacteria
Targeted nutrients that help repair the gut include:
- L-glutamine – fuels gut lining cells
- Zinc – supports immune and tissue integrity
- Omega-3 fatty acids – reduce inflammation
Dr. Linette carefully selects high-quality supplements to support your healing, based on your lab work and medical history.
Adopt a Colorful, Whole-Food Diet
Think of your plate as a rainbow of healing nutrients. Vibrant, whole foods provide antioxidants, polyphenols, fiber, and phytonutrients that naturally reduce inflammation and support immune resilience.
Include:
- Berries, leafy greens, cruciferous vegetables
- Root vegetables, wild-caught fish, healthy fats (like avocado and olive oil)
- Herbs and spices like turmeric, basil, and ginger
Whenever possible, choose organic and locally grown produce. Supporting the Poway Farmers Market not only nourishes your body but also connects you with your community’s cleanest, freshest foods.
Boost Immune-Regulating Nutrients
For patients dealing with autoimmune conditions, certain vitamins and minerals are essential for calming an overactive immune system:
- Vitamin D – critical for immune modulation
- Selenium – supports thyroid and antioxidant defense
- Magnesium – involved in over 300 enzymatic reactions
- Curcumin (from turmeric) – powerful anti-inflammatory
- Quercetin – supports histamine regulation and cellular repair
Dr. Linette offers custom supplement protocols that are based on functional lab testing, so you only take what your body truly needs.
Stay Hydrated and Limit Toxins
Staying hydrated helps your body flush out toxins and reduces joint stiffness, headaches, and fatigue—common symptoms in autoimmune conditions.
Drink filtered water throughout the day, and avoid:
- Plastic bottles (especially those containing BPA)
- Processed foods packaged in plastic or lined cans
Support your body’s natural detox pathways with:
- Cruciferous vegetables like broccoli, cauliflower, Brussels sprouts
- Dandelion greens, beets, and lemon water to assist liver function
Detoxification is not about deprivation—it’s about supporting your body’s natural ability to cleanse and heal, which is central to Dr. Linette’s approach to autoimmune wellness.
