BRS3(PM7) - Gut-Derived Inflammatory Signalling
1. Definition
Inflammatory signalling driven by endotoxin translocation and barrier dysfunction, linking gut ecology to systemic and neural inflammation.
Within BRS3, this PM captures inflammatory load entering from the gut side of the system, where barrier integrity, microbial ecology, and endotoxin burden shape downstream immune signalling [1][2][3].
2. Intervention Breakdown
Food-State Dominant
3. Functional Role
↓ LPS translocation; ↓ neuroinflammatory signalling
4. Mechanistic Basis
Summary
BRS3(PM7) links fibre-rich, fermented, and plant-diverse food patterns to lower endotoxin-linked inflammatory signalling and reduced gut-derived contribution to BRS3(FM1) - Anti-Inflammatory Signalling Tone [1][2][3].
Gut barrier context and inflammatory spillover
(Endotoxin-linked inflammatory load)
When gut-barrier function weakens, endotoxin and related inflammatory inputs may enter circulation more readily, increasing low-grade systemic inflammatory signalling [1].
(Dietary modulation context)
Prebiotic fibres, fermented foods, and broader plant diversity may support a lower-LPS environment through microbial and barrier-related effects, while zinc, vitamin A, and omega-3 provide additional supportive context.
(Cross-system placement)
Although native to BRS3 because the output is inflammatory tone, this PM depends strongly on gut-barrier and metabolic context imported through the cross-BRS links listed in §5.3.
5. Underlying Mechanisms and Requirements
5.1 Co-factors
- butyrate support
- omega-3
- vitamin A
- zinc
5.2 KCs (Key Constraints)
5.3 Cross-BRS Links
- BRS5(PM3) - Gut Barrier / Tight Junction Integrity
- BRS5(PM4)
- BRS6(PM2) - Insulin Sensitivity & Glucose Disposal
6. Dietary Levers
Diet
- Prebiotic fibres ← legumes, oats, onions, garlic, diverse plant foods
- Fermented foods ← yogurt, kefir, fermented vegetables
- Plant-diversity pattern ← varied whole plant foods supporting lower LPS burden
7. Lifestyle Levers
Lifestyle
- Sustained pattern quality matters more than short-term gut-focused additions.
- Sleep disruption, stress overload, and highly erratic eating may worsen gut-derived inflammatory pressure indirectly.
8. Scoreable Inputs & Modulation Signals
This PM is scoreable through gut-supportive diversity and lower-endotoxemia pattern signals.
