Modern diets with an Omega-6 to Omega-3 ratio of 20-50:1, compared to the evolutionary ideal of 1-2:1, drive chronic inflammation and chronic disease by shifting lipid mediator production toward pro-inflammatory pathways.

Reduce your intake of seed and vegetable oils (corn, soybean, sunflower, safflower) which are high in Omega-6. Increase intake of Omega-3 sources like fatty fish, algae, or flax/chia seeds. Aim for a dietary ratio closer to 4-5:1 rather than the typical 20:1 found in modern diets to lower systemic inflammation.

ModerateSupportsMEDIUM confidence
Overconsumption of n-6 PUFAs with low intake of n-3 PUFAs is highly associated with the pathogenesis of many modern diet-related chronic diseases... Due to higher ratios of n-6/n-3 in modern diets, larger quantities of LA- and AA-derived lipid mediators are produced, becoming the main causes of the formation of thrombus and atheroma, the allergic and inflammatory disorders, and the proliferation of cells...
