Rheumatoid arthritis, an autoimmune disorder causing joint pain and bone deformities, has long been a focus of research. While there is no cure, new findings highlight how gut health may play a role in managing the disease.
Recent studies, reviewed in *Nutrients*, examine the connection between rheumatoid arthritis and gut microbiome imbalances. Researchers are particularly interested in how certain bacteria in the gut, such as Prevotella copri, might contribute to inflammation and joint damage. Elevated levels of P. copri in the gut have been linked to early-stage rheumatoid arthritis, pointing to its potential role in the disease’s progression.
Additionally, Collinsella, another bacterium, has been associated with systemic inflammation in rheumatoid arthritis patients. Conversely, beneficial bacteria like Lactobacillus casei have been shown to reduce inflammatory markers and improve symptoms.
As reported by medicalnewstoday, the review suggests that diet may play an important role in managing rheumatoid arthritis by influencing gut bacteria. High-fiber foods can boost the production of short-chain fatty acids (SCFAs), which help lower inflammation and support immune function. A high-fiber diet has been linked to improved rheumatoid arthritis symptoms, while a low-fiber diet is associated with a 25% higher risk of developing the condition.
Foods like whole grains, fruits, vegetables, and omega-3-rich fish (e.g., salmon) are recommended for reducing inflammation. The Mediterranean diet, known for its heart health benefits, may also alleviate joint pain by promoting beneficial gut bacteria.
Experts caution that while the link between gut dysbiosis and rheumatoid arthritis is promising, more research is needed. Nevertheless, dietary changes, such as increasing fiber intake, limiting red meat, and reducing processed foods and sugar, may help manage symptoms.
Dr. Raj Dasgupta and Dr. Roger Sen, experts not involved in the study, emphasize the importance of personalized approaches and consulting healthcare professionals before making significant dietary changes.
