A plant-based diet comprised of fruits, vegetables, grains, and legumes may alleviate painful symptoms associated with rheumatoid arthritis (RA), according to a new review published in the journal Frontiers in Nutrition. Researchers with the Physicians Committee reviewed clinical trials and observational studies and found strong and consistent evidence that a plant-based dietary pattern can reduce inflammation and improve symptoms associated with RA. Possible mechanisms for pain relief include reduced inflammation, joint swelling, and BMI and improved gut bacteria as a result of consuming a plant-based diet. While more research is needed, the review adds to the evidence that diets rich in plants may be beneficial for autoimmune conditions. Other studies have found that a plant-based diet may be protective against other inflammatory conditions, including hypothyroidism, hyperthyroidism, and multiple sclerosis.
