BRS1(FM2) - Glycaemic Modulation of Neurotransmitter Balance
1. Definition
Influence of carbohydrate quality, meal sequencing, and glycaemic response on precursor partitioning and neurotransmitter bias.
2. Intervention Breakdown
Food-State Dominant
3. Functional Role
↑ insulin-mediated LNAA partitioning context; ↑ serotonin/catecholamine bias control; ↑ glucose stability
4. Mechanistic Basis (Implementation of PMs)
Meal-level carbohydrate quality and glycaemic response as modulators of LNAA transport and neurotransmitter bias.
PM2 governs LAT1 Competitive Transport Modulation.
Together, these PMs operationalise BRS1(FM2) as coordinated glycaemic modulation of neurotransmitter balance.
5. Underlying Mechanisms and Requirements
5.1 Cofactors and Substrates
| PM | Cofactors | KC substrates |
|---|---|---|
| BRS1(PM2) | B vitamins indirectly | choline, dietary protein, tryptophan, tyrosine, LNAAs (KC1) |
5.2 PMs (Primary Mechanisms)
5.3 KCs (Key Constraints)
5.4 Cross-BRS Links
- None listed
6. Dietary Levers
Diet
- Antagonistic glycaemic load ← refined sugars
- Fibre + low glycaemic load ← lentils
- Slow carbohydrates ← quinoa, sweet potato
- Slow carbohydrates + fibre ← oats
7. Lifestyle Levers
Lifestyle
- Meal timing and protein–carbohydrate composition may modulate neurotransmitter bias where relevant to this FM.
- Sleep regularity and stress-load management may influence downstream neurotransmitter tone (broader modifiers).
