Food Sensitivity Profile 1: A Guide to Identifying Hidden Food Triggers and Healing the Gut

Introduction: Why Food Sensitivity Testing Is Essential

Millions of people live with unexplained fatigue, brain fog, skin irritation, joint pain, or digestive issues—often without realizing that food sensitivities may be the hidden driver. Unlike classic food allergies, which trigger immediate reactions, food sensitivities are delayed, immune-mediated responses. They can appear hours or even days after eating a food, making them extremely difficult to identify without testing.

The Food Sensitivity Profile 1 test evaluates immune reactions to 96 of the most common foods in the Western diet using IgA and IgG antibody responses. By mapping your body’s immune reactivity, the test highlights which foods may be fueling inflammation, damaging your gut, and worsening chronic symptoms.

What Is Food Sensitivity Profile 1?

Food Sensitivity Profile 1 is a blood-based panel that measures IgA and IgG antibody responses to 96 commonly consumed foods. These include:

• Dairy proteins: beta-casein, casomorphin, cow’s milk, goat’s milk, whey

• Meats: beef, chicken, lamb, pork, turkey

• Fish & shellfish: cod, salmon, tuna, crab, shrimp, lobster

• Grains: barley, oats, rye, wheat, corn, rice, buckwheat, amaranth

• Legumes: peanuts, soy, kidney beans, navy beans

• Nuts & seeds: almond, cashew, walnut, pecan, sesame, mustard

• Fruits & vegetables: apple, banana, blueberry, tomato, broccoli, spinach, onion, garlic, and more

The test is offered as either blood draw or dried blood spot for convenience.

Unlike food intolerances (enzyme deficiencies like lactose intolerance), food sensitivities involve the immune system. Antigens in food proteins bind to antibodies and form immune complexes, which can trigger inflammation throughout the body.

Who Should Get Food Sensitivity Profile 1?

This test is appropriate for patients with:

• Digestive dysfunction: bloating, diarrhea, constipation, IBS

• Skin conditions: eczema, psoriasis, acne, chronic rashes

• Neurological symptoms: headaches, migraines, brain fog, cognitive changes

• Respiratory issues: asthma-like symptoms, bronchitis

• Musculoskeletal complaints: joint pain, stiffness, muscle swelling

• Autoimmune disorders: celiac, Crohn’s, ulcerative colitis, Hashimoto’s thyroiditis

• General inflammation: fatigue, systemic pain, low-grade fever

Food sensitivities affect an estimated 15–20% of the population, and many suffer for years without answers. For these individuals, Food Sensitivity Profile 1 provides clarity.

Benefits of Food Sensitivity Profile 1

1. Identifies Hidden Food Triggers

   • Many patients eat trigger foods daily without realizing they contribute to chronic symptoms. This test helps break that cycle.

2. Guides Personalized Diet Plans

   • Instead of generic elimination diets, the test pinpoints the exact foods your body reacts to.

3. Reduces Inflammation & Heals the Gut

   • Removing reactive foods can reduce leaky gut and allow the intestinal lining to repair.

4. Improves Energy, Mood, and Focus

   • Patients often report improved brain fog, fatigue, and mood once hidden food sensitivities are removed.

5. Supports Long-Term Disease Management

   • Addressing sensitivities lowers immune burden, benefiting autoimmune, cardiovascular, and metabolic health.

How the Test Works: Antibodies Measured

• IgA – the body’s first line of defense at mucosal surfaces like the gut and lungs; elevated IgA indicates gut-driven immune activity.

• IgG – the most abundant antibody; reveals delayed food reactions that drive systemic inflammation.

• IgG4 – measured on extended panels; linked to tolerance and chronic exposure.

• C3d – complement activation marker that signals heightened inflammation when immune complexes form.

What the Results Look Like

The report includes:

• Food Personalization Summary: non-reactive foods (safe) vs reactive foods (to avoid).

• Categories tested: dairy, meats, fish, shellfish, grains, legumes, nuts, seeds, fruits, vegetables, spices.

• Result ranges:

  • Green (In Control) = ≤10

  • Yellow (Moderate reaction) = 10.1–20

  • Red (High reactivity) = >20

Each reactive food also comes with notes on common food sources and hidden exposures (for example, cow’s milk proteins in baked goods, sauces, and processed foods).

Treatment Protocol Based on Food Sensitivity Profile 1

1. Elimination Phase (6–12 weeks)

• Remove all high and moderate reactivity foods from the diet.

• Replace with nutrient-dense, low-reactivity foods identified as safe.

• Support gut healing with:

  • BPC-157 – promotes mucosal repair.

  • KPV – reduces intestinal inflammation.

  • Curcumin Complex – natural NF-κB modulator.

  • Omega 1300 – anti-inflammatory support.

2. Gut Repair & Microbiome Support

• Add probiotics or prebiotics tailored to Gut Zoomer results if run in parallel.

• Consider digestive enzymes (e.g., Complete Digestive Support) if food breakdown markers suggest insufficiency.

• Ensure adequate zinc, vitamin D, and glutamine to fuel gut healing.

3. Reintroduction Phase

• Gradually reintroduce moderate-reactivity foods one at a time after the elimination phase.

• Monitor symptoms carefully; keep a food diary.

• Foods still triggering symptoms remain excluded longer term.

4. Maintenance & Long-Term Strategy

• Retest in 6–12 months to evaluate progress and tolerance shifts.

• Use results to build a sustainable, anti-inflammatory nutrition plan.

• Monitor related biomarkers (CRP, ferritin, thyroid antibodies) to track systemic improvements.

Clinical Outcomes Seen with Food Sensitivity Testing

• GI health: IBS, bloating, diarrhea, and constipation improve after eliminating reactive foods.

• Skin health: eczema, acne, and rashes reduce once immune triggers are identified.

• Energy & cognition: patients experience less brain fog, headaches, and fatigue.

• Autoimmune management: lowering antigen load helps calm overactive immune systems.

• Respiratory function: some see improved asthma-like symptoms when reactive foods are removed.

Conclusion: Testing, Not Guessing

Food sensitivities are a hidden but powerful driver of chronic inflammation. The Food Sensitivity Profile 1 test offers patients and providers a clear, personalized roadmap to uncover food triggers, reduce immune stress, and restore health.

If you are struggling with gut issues, fatigue, headaches, skin flares, or autoimmune disease, Food Sensitivity Profile 1 may be the key to unlocking relief. With accurate testing and guided protocols, patients can heal their gut, lower inflammation, and improve long-term wellness.
