Abstract

Aim: Rheumatoid arthritis is an inflammatory illness characterized by persistent and systemic inflammation. There is just a little amount of research on nutrition and RA progression. The goal of this research is to see whether there's a link between main eating trends and RA activity. Methods: In Kermanshah, Iran, 183 individuals with RA were studied in cross-sectional research. The American College of Rheumatology's 2010 criteria were used to diagnose RA. The disease activity score 28 and nutritional information from a reliable 147-item food frequency questionnaire were used to assess RA activity. Factor analysis was used to extract dietary patterns. Results: The researchers discovered three main eating trends, which they named. Individuals in the highest tertile of a high protein anti-inflammatory dietary pattern that emphasizes consumption of dairy products, red meats, white meats, vegetables oils, condiments, vegetables and fruits as well as low in salts and refined grain had lower DAS-28 scores than those in the first tertiles (T3 = 2.09 ± 0.14 vs. T1 = 3.75 ± 0.13; P-value = 0.001) after controlling for potential confounders. Patients in the top tertile of the low fiber dietary pattern had higher DAS-28 scores than those in the bottom tertile (T3 = 3.40 ± 0.15 vs. T1 = 2.95 ± 0.15; P-value = 0.036) than those in the bottom tertile. Conclusion: This research found an inverse connection between RA activity and adopting a high-protein anti-inflammatory dietary pattern. Furthermore, adopting a low-fiber dietary pattern may be linked to increased RA disease activity. To confirm such a relationship, further research is needed in the future. © 2022 European Society for Clinical Nutrition and Metabolism
