Arachidonic Acid / EPA Ratio
The AA/EPA ratio compares arachidonic acid, an omega-6 precursor of pro-inflammatory eicosanoids, with EPA, a precursor of anti-inflammatory mediators. A high ratio indicates a pro-inflammatory fatty acid balance typical of Western diets, while a lower ratio suggests better inflammatory balance. It can be lowered by reducing omega-6-rich oils and increasing EPA intake.
