The Claim

In adults with rheumatoid arthritis, a 12-week dietary intervention based on the Mediterranean diet or Irish Healthy Eating Guidelines results in a mean weight loss of 0.6–0.9 kg and a modest reduction in BMI, but these changes do not account for improvements in dietary inflammatory potential or patient-reported outcomes.

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In adults with rheumatoid arthritis, following a Mediterranean diet or Irish Healthy Eating Guidelines for 12 weeks leads to a small weight loss and slight drop in BMI, but these changes alone do not explain why inflammation-related dietary scores and patient symptoms improved.

See the scientific wording

In adults with rheumatoid arthritis, a 12-week dietary intervention based on the Mediterranean diet or Irish Healthy Eating Guidelines leads to significant weight loss (mean reduction of 0.6–0.9 kg) and modest BMI reduction, but these changes are not sufficient to explain improvements in dietary inflammatory potential or patient-reported outcomes.

Why this might work

Eating more oily fish, fruits, vegetables, whole grains, and olive oil replaces harmful fats in cell membranes with anti-inflammatory fats, which stops the production of 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. This lowers overall inflammation in the body without needing weight loss.

  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

    People with rheumatoid arthritis who ate healthier for 12 weeks got less inflammation from their diet, but didn’t feel better — and it wasn’t because they lost weight. The improvement came from eating more fruits, veggies, and healthy fats, not from losing pounds.
