Lecture Notes on Immune Response, Allergies, and Gut Health

Overview of Allergies and Gut Health

• Lifelong allergies may improve with gut health rehabilitation.
• Patients often seek treatment for other conditions (e.g., IBS, autoimmune diseases) but experience allergy relief through gut and immune system healing.
• Understanding the nuances of allergies is crucial for addressing root causes.

Definitions of Key Terms

1. Food Allergy

• Classic example: Peanut allergy causing anaphylactic reactions (involves IgE antibodies).
• Reactions occur within minutes, usually identified in childhood.

2. Food Intolerance

• Example: Lactose intolerance due to enzyme deficiency, not an immune dysfunction.
• Typically present from a young age and can worsen with age.

3. Food Sensitivity

• Immune reactions mediated by IgG or IgA antibodies.
• Loss of tolerance to foods as individuals age, potentially due to gut health issues.
• Increasing cases of food sensitivities in modern populations.

Root Causes of Allergies

• The increase in allergic reactions and food sensitivities is attributed to environmental changes, not solely genetic factors.
• The relationship between gut health and allergies:
  • Poor gut health may lead to increased immune reactivity to foods.

Celiac Disease

• An autoimmune condition triggered by gluten, now prevalent in about 3% of the population, up from 1% 15 years ago.

Allergy Testing

1. Blood Panels

• Tests for IgE antibodies against environmental agents and foods.

2. Skin Prick Tests

• Direct exposure to allergens to see immediate reactions.

Limitations of Traditional Tests

• Tests may use synthetic versions of allergens, leading to inaccurate results.
• False positives and negatives can occur, making interpretation complex.

Thematic Information from Tests

• Patterns in reactions can indicate an overactive immune system but may not pinpoint specific issues.

Food Sensitivity and Immune Response

• Food reactions are not detected in traditional allergy tests, emphasizing the need for a broader understanding of immune reactions.
• Patients may improve by identifying and removing triggers from their diet and addressing gut health.

The Role of T Regulatory Cells

• T regulatory cells help distinguish harmful from non-harmful substances in the gut, influencing overall immune response.
• Chronic inflammation can arise from a dysregulated immune response and poor gut health.

Steps for Recovery

1. Remove Triggers

• Implement an elimination diet to remove gluten, dairy, corn, and soy.
• Temporarily eliminate all processed foods to reduce inflammation.

2. Repair Gut Health

• Focus on nutrients that aid the intestinal lining, such as collagen, probiotics, and omega-3 fatty acids.
• Supplements like vitamin D, zinc, and fish oil can enhance healing.

3. Reintroduce Foods Carefully

• Monitor reactions to reintroduce foods one at a time after the repair phase.
• Reintroduction helps identify specific sensitivities and guides future dietary choices.

Conclusion

• Acknowledge the impact of diet on health and encourage self-exploration.
• Seek professional guidance when testing and interpreting results for autoimmune conditions.
