Surprising Findings
Higher dietary inflammation was not linked to worse knee pain scores (KOOS), despite strong assumptions in public health messaging.
Most wellness content claims anti-inflammatory diets directly reduce joint pain—this study contradicts that for knee osteoarthritis, showing no clear association.
Practical Takeaways
If you have knee osteoarthritis, focus on losing weight and managing overall health conditions—your diet may help more by reducing BMI and comorbidities than by directly easing knee pain.

When your diet messes up your gut bacteria, it can cause your whole body to be inflamed, which might make your muscles and joints hurt—but eating anti-inflammatory foods like veggies, fish, and nuts can help calm that down and ease the pain.
For older adults with knee arthritis, eating more inflammatory foods doesn’t seem to make their knee pain or function worse, but it does tend to go hand-in-hand with being heavier, having more other health problems, and feeling pain in more joints.
Most people over 45 with knee arthritis are women, they’re around 65 years old on average, and most of them are overweight or obese.
Most people over 45 with knee arthritis also have other health problems—like high blood pressure—and almost 8 out of 10 say their back or other joints hurt too, not just their knee.
People with knee arthritis in their 40s to 80s tend to eat foods that slightly spark inflammation, like processed meats and sugary snacks—but when you adjust for how much they eat overall, their diet is a bit less inflammatory than it first looks.
