    Your Omega 6:3 Ratio Explained

    You've probably heard that modern diets are dangerously skewed toward omega-6 — that we've drifted from an ancestral 1:1 ratio to something closer to 20:1, and that inflammation, heart disease and half of modern ill health follow from it. It's one of the most repeated claims in nutrition. It's also one of the most contested. In this episode, the FitnessGenes team digs into what omega-6 and omega-3 fats actually do in the body, where the ratio idea came from, and why a lot of researchers now argue that total omega-3 intake matters more than the balance between the two. We look at the FADS1 and FADS2 genes — which govern how efficiently you convert plant-based ALA into the EPA and DHA your body can use, and vary substantially between individuals — and what that means for whether you need fish, algae or a supplement to hit your numbers. Plus: how much omega-3 is actually enough, whether seed oils deserve their reputation, and what to look for on a supplement label.
