What Happens After Food Intolerance Testing? Why Nutritional Support Matters

What Happens After Food Intolerance Testing? Why Nutritional Support Matters

Results Are Only the Beginning

An IgG test shows how your immune system responds to foods, but lasting improvement depends on what you do next.

How Nutrition Guidance Helps

  • Spot patterns linking results with symptoms.

  • Build a balanced elimination plan that avoids nutrient gaps.

  • Reintroduce foods safely to fine-tune your diet.

  • Address other factors like stress, gut flora or histamine issues.

Why Results and Feelings Don’t Always Match

  • Negative test, symptoms remain – causes may be non-immune (stress, SIBO, FODMAPs).

  • Positive test, no symptoms – IgG can rise from frequent exposure alone.

  • Few positives, big relief – simply removing processed foods often calms inflammation.

Key Takeaway

Testing offers a snapshot, not a verdict. Pair results with professional support, symptom tracking and gradual dietary adjustments for the best outcome.
