Food Inflammation Testing

Understanding Food Inflammation Testing: A Comprehensive Guide

Are you experiencing unexplained fatigue, digestive issues, brain fog, or chronic inflammation? The foods you eat every day could be the hidden culprit. Food sensitivities affect more than 100 million people worldwide, yet they remain notoriously difficult to identify because symptoms can be delayed up to 72 hours after eating the offending food.

At Natalie McGrath’s practice, we utilize advanced food inflammation testing to help you uncover the root causes of your symptoms and create a personalized path to optimal health.

What Is Food Inflammation Testing?

Food inflammation testing, specifically the FIT 176 (Food Inflammation Test), is a revolutionary diagnostic tool that goes far beyond traditional food allergy testing. This patented test uses technology that measures both IgG antibodies and immune complexes, identifying food sensitivities, inflammation, and leaky gut from a single test.

Unlike conventional IgE allergy tests that detect immediate reactions, the FIT 176 test identifies delayed food sensitivities that can trigger chronic inflammation and contribute to a wide range of health conditions.

How Is the FIT Test Different?

The FIT test stands apart from other food sensitivity tests in several critical ways:

Multi-Pathway Approach

The test uses a patented multiple pathway approach that measures IgG1-4 and complement activation via the marker C3d, which accurately indicates inflammation at the gut lining. This comprehensive approach eliminates the false positives commonly associated with IgG-only testing, providing more accurate and actionable results.

Comprehensive Food Panel

There is an option to test sensitivities of  22, 132 and 176 different foods, colorings and additives spanning most major food groups, including:

• Dairy products
• Grains and gluten-containing foods
• Fruits and vegetables
• Meats, poultry, and fish
• Nuts, seeds, and legumes
• Shellfish and seafood
• Spices and herbs
• Food additives and colorings
• Microbials including Candida

 

Who Should Consider Food Inflammation Testing?

The FIT test is particularly valuable for individuals experiencing:

• Digestive issues: bloating, gas, constipation, diarrhea, IBS
• Chronic inflammation: joint pain, arthritis, muscle aches
• Autoimmune conditions: thyroid disorders, celiac disease, rheumatoid arthritis
• Neurological symptoms: migraines, brain fog, difficulty concentrating
• Skin problems: eczema, psoriasis, acne, rashes
• Weight management challenges: difficulty losing weight despite diet and exercise
• Fatigue and low energy: unexplained tiredness and lethargy
• Mood disturbances: anxiety, depression, irritability

Food sensitivities and related diseases affect at least 100 million people worldwide, with prevalence increasing to more than 50% in adults and more than 70% in children in recent years.

Understanding the Science Behind the Test

IgG Antibodies and Food Sensitivities

IgG food sensitivity is triggered by the binding of complement to IgG food antigen complexes, causing an inflammatory response, which is a delayed hypersensitivity reaction in which symptoms appear anywhere from hours to days after eating the offending food.

This delayed response is why food sensitivities are so challenging to identify without proper testing. You might eat a trigger food on Monday and not experience symptoms until Wednesday, making it nearly impossible to connect the dots without comprehensive testing.

The Role of Complement Activation

The FIT  test measures both IgG antibodies and complement fragments. Immune complexes activate Complement which becomes bound to the immune complex lattice, and activation of Complement causes tissue inflammation and the symptoms associated with food sensitivities. This dual measurement significantly increases the test’s accuracy over IgG-only tests.

 

The Testing Process

The FIT  test is simple and convenient:

1. Sample Collection: The test can be performed via a simple finger prick blood spot test or blood draw, making it accessible for at-home collection
2. Laboratory Analysis: Samples are analyzed in a CLIA High Complexity Laboratory with FDA-registered and ISO 13485-compliant standards
3. Results: Turnaround time is typically 7-10 business days
4. Interpretation: You receive a comprehensive, color-coded report that’s easy to understand

 

Implementing Your Results: The Elimination Diet

Once you receive your FIT 176 test results, the next step is implementing an elimination diet based on your specific sensitivities. Eliminating all identified IgG-positive foods after testing can reduce stress on the immune system, decrease inflammation (helping to heal “leaky gut”), resolve food cravings, and reduce the potential for eating disorders.

The elimination process typically follows this approach:

1. Remove Reactive Foods: Begin by eliminating foods that show moderate to severe reactions (levels 2-4+)
2. Healing Phase: Allow 3-6 months for gut healing and inflammation reduction
3. Symptom Monitoring: Track improvements in your symptoms throughout the elimination period
4. Reintroduction Protocol: Gradually reintroduce foods one at a time to assess tolerance
5. Maintenance: Develop a sustainable long-term eating plan based on your body’s responses

The Connection Between Food Sensitivities and Chronic Conditions

Research and clinical evidence increasingly support the link between food sensitivities and various chronic health conditions:

Autoimmune Diseases

Food sensitivities can trigger and exacerbate autoimmune conditions by increasing intestinal permeability and promoting systemic inflammation. Identifying and removing trigger foods may help reduce autoimmune symptoms and flare-ups.

Gastrointestinal Disorders

Many individuals with IBS, inflammatory bowel disease, and other digestive disorders have underlying food sensitivities contributing to their symptoms. Addressing these sensitivities can lead to significant improvement in gut health and digestive function.

Neurological and Cognitive Issues

The gut-brain axis means that inflammation triggered by food sensitivities can impact cognitive function, mood, and neurological health. Many people experience improvements in brain fog, migraines, and concentration after identifying and eliminating trigger foods.

Weight Management

Chronic inflammation from food sensitivities can interfere with metabolism, hormone balance, and the body’s ability to lose weight. Addressing food sensitivities often helps resolve stubborn weight issues that haven’t responded to traditional diet and exercise approaches.

Why Choose Professional Testing Over Elimination Diets?

While elimination diets have their place, professional food inflammation testing offers several advantages:

• Precision: Identifies specific foods causing inflammation rather than guessing
• Efficiency: Saves months of trial and error with various elimination protocols
• Comprehensive: Tests 176 foods simultaneously, including additives and colorings often missed in self-guided eliminations
• Objectivity: Provides measurable, scientific data about your body’s immune responses
• Gut Health Assessment: Includes markers for leaky gut, providing a complete picture of digestive health

Taking the Next Step Toward Better Health

If you’re struggling with unexplained symptoms, chronic inflammation, or digestive issues, food inflammation testing could be the key to unlocking your path to wellness. The FIT  test provides the comprehensive data needed to make informed decisions about your diet and health.

At Natalie McGrath’s practice, we’re committed to helping you identify the root causes of your health concerns and develop personalized strategies for healing. Food inflammation testing is just one of the powerful tools we use to support your journey toward optimal health.

Ready to Discover Your Food Sensitivities?

Understanding how your body responds to different foods empowers you to make choices that support rather than sabotage your health. With the FIT  test, you can move beyond guesswork and gain clear insights into the foods that are helping or harming your body.
