This study is a 12-week dietary intervention trial conducted in patients with rheumatoid arthritis. Participants will be assigned to three different dietary groups: gluten-free diet, Mediterranean diet, and control diet. The aim is to investigate the effects of these dietary patterns on disease activity, quality of life, and dietary inflammatory index.
Disease activity will be assessed using the DAS28 score, while quality of life will be evaluated using the SF-12 questionnaire. Dietary inflammatory index (DII) will be calculated based on dietary intake data collected throughout the study period.
Participants will be followed regularly during the 12-week intervention period, and changes in clinical and nutritional outcomes will be analyzed to determine the impact of dietary patterns on rheumatoid arthritis progression and patient well-being.
