The eFEct of an Anti-Inflammatory Diet for Knee oSTeoarthritis (FEAST) Trial: Baseline Characteristics and Relationships With Dietary Inflammatory Index.

Randomized Controlled Trial

Human

2025 Aug

This study looked at what people ate and how it related to their knee pain and other health issues. It found that eating more inflammatory foods didn’t make knee pain worse in most ways, but did link to being heavier, having more health problems, and feeling pain in more body parts — just like the claim says.

Similar Assertions

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.

If you're overweight and have painful knees from arthritis, following a healthy, anti-inflammatory diet—like eating more whole foods and omega-3s while cutting back on sugary carbs—over 9 weeks might help reduce your knee pain, make it easier to move around, and improve how you feel overall.
