BRS5(KC3) - Barrier-Supportive Nutrient Sufficiency
1. Ambition
Maintain barrier-supportive nutrient sufficiency so epithelial renewal, mucosal immune containment, and selective gut permeability remain stable.
2. Shared Biological Pool
- Omega-3 fatty acids ← oily fish, algae, eggs
- Vitamin A precursors and retinol ← eggs, liver, orange vegetables
- Zinc ← seafood, meat, legumes, seeds
- Glutamine-supportive amino-acid pool ← fish, eggs, poultry, legumes
3. Biological Importance
Gut-barrier function depends on microbial metabolites and on adequate structural and immune-supportive nutrient context [Mohammad and Thiemermann, 2021; Khailova et al., 2017]. When support is weak, epithelial integrity and selective permeability become harder to maintain, increasing vulnerability to inflammatory spillover and unstable gut-brain signalling.
