The Claim

In adults with rheumatoid arthritis, adherence to a Mediterranean diet or the Irish Healthy Eating Guidelines for 12 weeks results in a mean reduction of 1.5 and 2.1 units, respectively, in the energy-adjusted dietary inflammatory index (e-DII), indicating a shift toward a less inflammatory dietary pattern, without associated improvements in patient-reported pain or physical function.

In plain English

Among adults with rheumatoid arthritis, following either a Mediterranean diet or the Irish Healthy Eating Guidelines for 12 weeks lowers a measure of dietary inflammation by 1.5 to 2.1 units, but does not change reported pain levels or physical function.

See the scientific wording

In adults with rheumatoid arthritis, adherence to either a Mediterranean diet or the Irish Healthy Eating Guidelines for 12 weeks significantly improves the energy-adjusted dietary inflammatory index (e-DII), with mean reductions of 1.5 units in the Mediterranean group and 2.1 units in the Healthy Eating Guidelines group, indicating a shift toward a less inflammatory dietary pattern, though this change is not linked to measurable improvements in patient-reported pain or physical function.

Why this might work

Eating more fish, vegetables, fruits, whole grains, and olive oil replaces harmful fats in cell membranes with omega-3 fats, which stops the body from making inflammatory chemicals. These foods also strengthen the gut lining, preventing toxins from leaking into the blood, and provide antioxidants that block signals that trigger inflammation. Together, these changes lower the overall level of inflammation in the body.

  1. Study: Comparison of mediterranean and healthy eating guideline interventions on the dietary inflammatory index in rheumatoid arthritis: results from a dietary randomised controlled intervention trial

    This study found that people with rheumatoid arthritis who ate either Mediterranean food or followed Ireland’s healthy eating rules for 12 weeks had less inflammatory diets, but their pain and movement didn’t get better. So the diet changed what they ate, but not how they felt.
