Summary

This study tests whether a personalized diet, based on the latest Nordic Nutrition Recommendations, can reduce disease activity and cardiovascular risk in people newly diagnosed with rheumatoid arthritis. About 150 participants will be randomly assigned to either a diet following these recommendations or a nutrient-rich diet, alongside their usual medications. The trial will track inflammatory markers, blood pressure, cholesterol, and body composition over nine months to see if dietary changes can complement standard treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Personalized diet based on Nordic Nutrition Recommendations 2023 or a nutrient-rich diet
What this could lead to
If successful, this could provide evidence-based dietary advice to help manage RA symptoms and lower cardiovascular risk.
What could go wrong
The trial is relatively small and early, and diet effects may be modest or vary among individuals. Adherence to the diet over time could be challenging.
