This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This 12-week study explores whether a Mediterranean-style diet—enhanced with fermented foods like kefir and kombucha—can help reduce inflammation and improve quality of life in people with rheumatoid arthritis. Half of the 100 participants will receive a personalized eating plan with weekly support from dietitians, food deliveries, and cooking workshops. The other half will receive general healthy eating advice to compare results.
Research suggests that what we eat can influence the bacteria in our gut and affect inflammation in rheumatoid arthritis. This trial is testing whether a specific diet pattern, along with foods known to support healthy gut bacteria, could be a practical way to help manage the disease alongside current medications.

If you are randomly assigned to the diet intervention group, you'll work with a registered dietitian to create a personalized eating plan based on the Mediterranean diet with added fermented foods. You'll receive weekly check-ins with your dietitian, food deliveries, and access to cooking workshops over 12 weeks. Throughout the study, researchers will measure changes in your inflammation markers, gut health, disease symptoms, and overall quality of life through blood tests, stool samples, and questionnaires. The control group receives general healthy eating guidance for comparison.
