Gut-Inflammation, Allergies, and Metabolic Health Masterclass

Understanding the Gut-Inflammation Connection

Your metabolism is the sum total of all the metabolic reactions happening in your body — shaping how you feel today and determining your health trajectory for years to come. When food sensitivities go unaddressed, the result is chronic meta-inflammation: a smoldering, systemic inflammatory signal that disrupts insulin signaling, promotes weight gain, accelerates cardiovascular risk, erodes bone density, impairs brain function, and ultimately drives mitochondrial dysfunction at the cellular level. It starts in the gut — and it starts with what you eat every day.

Five Immune Pathways — Why Testing All Five Matters

15 to 20% of adults have some form of food sensitivity or intolerance, yet most testing panels only scratch the surface. The EAT144 test measures all five immune pathways — giving practitioners and patients a complete, accurate picture of how the immune system is responding to food.

IgE
Classic food allergy

The traditional food allergy marker. Drives immediate hypersensitivity reactions, mast cell activation, basophil elevation, histamine release, and in severe cases, anaphylactic risk.

IgG4
Allergen marker

Acts as a blocker for IgE — reducing the severity of immediate reactions. But when IgG4 is chronically elevated, it signals persistent allergen exposure and can contribute to the development of autoimmunity over time.

IgG
Delayed sensitivity

Reactions can take up to 72 hours to appear — making it nearly impossible to connect symptoms to a specific food without testing. A major driver of low-grade systemic inflammation, insulin resistance, and weight gain that most people never identify.

C3bd
Complement amplifier

The complement immune system runs independently — but when activated, it dramatically amplifies IgG responses and drives pro-allergenic TH2 immune activity. More C3bd reactivity means the immune system stays locked in a state of high alert, making all other sensitivities worse.

IgA
Mucosal barrier health

Secretory IgA is your gut's first line of defense. When elevated, it signals the mucosal immune system is in an active battle. When depleted, the mucosal barrier has been worn down — leaving the gut exposed to bacterial toxins, food-derived peptides, and systemic inflammation.

EAT144
144 foods tested

Most panels test approximately 88 foods. EAT144 tests 144 — using microarray technology rather than ELISA for greater sensitivity, a wider dynamic range, and more reliable results. CCD blockers eliminate false-positive IgE readings, and concentrated extracts produce a cleaner, more refined signal.

What You'll Learn

Key Topics Covered

How chronic stress elevates IL-6, upregulates claudin-2, and breaks down tight junctions — making gut permeability a direct consequence of a dysregulated stress response

The downstream effects of LPS endotoxemia: insulin resistance in muscle, liver, and adipose tissue; neuroinflammation; microglial activation; and impaired beta cell function

IgG food antibodies in obese children linked to increased carotid intimal thickness and elevated atherosclerosis risk — published evidence from 2008

Clinical trial data: an IgG-based elimination diet produced 8.6 kg of weight loss and 5 kg of body fat reduction in six months, versus 1 kg in the calorie-restricted group — with improved sleep and reduced glucose

The gut-brain connection: how food sensitivity-driven inflammation reduces neurogenesis, impairs neurotransmitter metabolism, and contributes to brain fog, anxiety, and mood disorders

Adipokines, obesity, and the vicious cycle: how excess visceral fat generates inflammatory compounds that further erode the gut barrier and deepen insulin resistance

"The one thing that people need to do every day is eat. And if you're eating foods on a regular basis that are triggering inflammatory signaling, you're pushing down this funnel towards cellular, mitochondrial disruption and damage to your DNA."
