Food Sensitivities
Food sensitivities aren't permanent sentences. They're signals that your gut barrier is compromised and your immune system is reacting to food proteins that shouldn't be in your bloodstream. Fix the barrier, calm the immune response, and most sensitivities resolve.
Food sensitivities — distinct from true allergies — are driven by intestinal permeability, gut microbiome imbalance, and immune dysregulation that cause delayed inflammatory reactions to foods that should be tolerated. Signal-Based Medicine™ tests for IgG-mediated food reactions while addressing the underlying gut dysfunction that creates sensitivities in the first place.
Symptoms
- Bloating after eating
- Fatigue (especially post-meal)
- Brain fog
- Joint pain
- Skin issues (eczema, acne)
- Headaches
- Sinus congestion
- Mood changes
- Digestive distress
- Weight gain or inability to lose weight
Root Causes
True food allergies (IgE-mediated) are immediate and can be life-threatening. Food sensitivities (IgG-mediated) are delayed, dose-dependent inflammatory reactions. They develop when a compromised gut barrier allows food proteins to contact your immune system. The reaction isn't to the food itself — it's to the food being in a place it shouldn't be (your bloodstream). That's why elimination diets without gut repair lead to an ever-shrinking list of 'safe' foods.
Testing
- IgG food sensitivity panel
- Zonulin and permeability markers
- GI-MAP
- Secretory IgA
- Inflammatory markers
- VITAL Index assessment
Treatment Approach
We identify your reactive foods AND repair the gut barrier that's creating the sensitivities. Short-term elimination reduces immune activation while we restore intestinal integrity, microbiome balance, and immune regulation — allowing food reintroduction.
Frequently Asked Questions
Are food sensitivity tests accurate? IgG food sensitivity testing identifies foods your immune system is reacting to. It's most useful when combined with gut barrier assessment — because the goal isn't permanent avoidance but understanding why your body is reacting and fixing the underlying cause.
Will I have to avoid these foods forever? Usually not. Most food sensitivities resolve when the gut barrier is repaired and immune function normalizes. We use short-term elimination while addressing root causes, then systematically reintroduce foods.
What's the difference between food allergy and food sensitivity? Food allergies (IgE) are immediate, can be severe or life-threatening, and are typically lifelong. Food sensitivities (IgG) are delayed (hours to days), dose-dependent, and often reversible when gut health is restored.
