Does Omega-3 Reduce Inflammation?

Everyone's heard the omega-6 to omega-3 ratio talked about like it's a measurement of how inflamed you currently are. It isn't — and even the researcher who invented the actual validated alternative test says so directly. I break down what the ratio actually measures, the real mechanisms behind omega-3's anti-inflammatory effects (there's a whole pathway most content never covers), and then pressure-test the three major cardiovascular trials that somehow all reached different conclusions testing nearly the same thing. What's covered: Why the omega-6:3 ratio is a poor metric — arachidonic acid isn't driven by how much omega-6 you eat, and it isn't the villain it's made out to be The real mechanism: eicosanoids, resolvins, and a direct gene-suppression pathway (NF-κB/PPAR-γ) that almost never gets mentioned REDUCE-IT's 25% cardiovascular risk reduction — and the genuine methodological controversy behind it Why STRENGTH failed using a seemingly better-absorbed formulation, and what it revealed about atrial fibrillation risk VITAL's "failed" headline that buried a real 28% reduction in heart attacks The genuinely uncomfortable finding: the original reasoning behind the 8-12% Omega-3 Index target hasn't held up as well as people assume What to actually eat, test, and supplement — and the real gap between the UK's 450mg guideline and what optimal looks like Studies & Sources: Harris WS.
