Autoimmune Disorders

Food Intolerance and Autoimmune Disorders: Understanding the Link

Autoimmune disorders occur when the immune system mistakenly attacks the body’s own tissues, leading to chronic inflammation and organ dysfunction. Examples include

  • Rheumatoid Arthritis: Joint flares linked to immune-triggering foods
  • Hashimoto’s Thyroiditis: Food-driven inflammation affecting thyroid balance
  • Psoriasis & Lupus: Gut-skin-immune axis involved in symptom severity
  • Multiple Sclerosis: Possible role of gut-derived inflammation in nervous system attacks

While genetics and environmental factors play key roles, emerging research shows that food intolerances—particularly IgG-mediated hypersensitivities—can contribute to immune system imbalance and inflammation, worsening autoimmune conditions like

Immune System Overactivation

In IgG food intolerance, the immune system produces IgG antibodies against specific foods. Unlike immediate IgE allergies, IgG reactions are delayed and can lead to chronic, low-grade inflammation.

This persistent immune activation may:

  • Overstimulate immune pathways
  • Trigger cross-reactivity (the immune system confuses food proteins with body tissues)
  • Exacerbate autoimmune flare-ups

 Gut Health, Leaky Gut & Autoimmunity

Many autoimmune disorders are associated with gut barrier dysfunction (leaky gut). When the gut lining is compromised:

  • Undigested food particles and toxins can enter the bloodstream
  • This triggers immune responses, including IgG antibody production
  • The cycle of gut inflammation and immune activation may fuel autoimmunity

How IgG Testing (ImuPro) Supports Management

The ImuPro test helps detect food-specific IgG antibodies, identifying which foods may be contributing to chronic inflammation.

  • Removing these trigger foods may:
  • Reduce immune burden
  • Calm inflammatory pathways
  • Improve gut health and digestion
  • Support symptom relief in autoimmune conditions
