A study published in Osteoarthritis and Cartilage (Vol. 20, Issue 5, pp. 382–387) examined joint inflammation in arthritis patients with an average age of 60 using contrast-enhanced MRI. Researchers measured synovial thickening and cartilage damage—objective markers of joint inflammation.
They found a clear relationship between blood fatty acid patterns and inflammation. Higher circulating omega-3 fatty acid levels were associated with less joint inflammation, while higher omega-6 fatty acid levels were associated with more inflammation. In short, inflammation was inversely related to omega-3 intake and directly related to omega-6 intake.
Bottom line: a higher omega-3–to–omega-6 ratio was linked to healthier joints and less inflammatory damage—highlighting diet as a meaningful driver of arthritis activity, not just a background factor.
