Comparison of the effects of soy milk and cow's milk intake on the levels of inflammatory markers, proinflammatory cytokines and oxidative stress in patients with rheumatoid arthritis
The purpose of this study is evaluation the effect of soy milk intake on the levels of inflammatory markers and oxidative stress in patients with rheumatoid arthritis. This randomized crossover clinical trial was performed on 30 patients. This study had two 4-week intervention periods: 1) regular diet with soy milk (200 ml per day) and 2) regular diet with cow’s milk (200 ml per day). For putting the subjects in different groups, random sequencing generated in SPSS software was used. The wash‐out period was two weeks. From the patients who received soy milk in the first intervention period was asked to replace cow's milk instead of soy milk, and vice versa. Each patient received both diets. Variables including anthropometric indicators, blood pressure, inflammatory markers and oxidative stress were measured before and after of each intervention.
