BRS3(KC3) - Essential Fatty Acid Balance
1. Definition
Availability and balance of omega-3 and omega-6 fatty acids required for inflammatory signalling and resolution pathways.
2. Constraint Role
Maintains omega-3/omega-6 substrate availability and balance for eicosanoid signalling, membrane resilience, and specialized pro-resolving mediator generation [1][2][3]. Supports effective operation of inflammatory-tone, lipid-protection, and resolution mechanisms when essential fatty acid balance remains adequate rather than chronically skewed.
3. Supporting Inputs/Substrates
- EPA/DHA ← oily fish, fish roe, algal oil
- Whole-food PUFA balance ← nuts, seeds, minimally processed plant-fat sources
4. Biological Importance
Essential fatty acid balance influences the substrate pool available for inflammatory signalling and for generation of specialized pro-resolving mediators [1][2]. Long-chain omega-3 fatty acids are also structural and signalling lipids relevant to brain and membrane function [3]. When omega-3 availability is low relative to inflammatory demand, or diets are skewed toward oxidized and imbalanced PUFA exposure, inflammatory tone and resolution capacity may be compromised.
5. Connected Mechanisms
- Functional Mechanisms
- Primary Mechanisms
6. Constraint Stressors / Burdens
- low EPA/DHA intake over time
- chronically imbalanced omega-6-dominant food patterns
- repeated intake of oxidized oils and fried-fat exposure
- low whole-food fat quality and limited marine-fat coverage
- lipid peroxidation burden damaging polyunsaturated fatty acid pools
