Broad Spectrum of Food Reactions
- Adverse reactions to foods cover a wide range of symptoms beyond classic allergies, including bloating, heartburn, and fatigue.
- These reactions encompass both immune and non-immune mediated processes.
Immune Responses Vary Widely
- Food allergies are an IgE-driven immune response causing classic allergy symptoms like hives and throat closing.
- Non-IgE immune reactions exist and cause damage without classic allergic reactions.
Non-Allergic Immune Food Responses
- Some immune-mediated food reactions like celiac disease involve immune attack on intestinal lining without classic allergies.
- These non-IgE immune reactions can damage tissues and are hard to detect with standard allergy tests.
