The purpose of the study is to assess whether, in individuals with rheumatoid arthritis, a low-fat, vegan diet improves pain and other subjective symptoms more effectively than a control supplement or a placebo. The principal measure is pain as measured by Visual Analog Scale (VAS) and disease activity as measured by number of painful swollen and tender joints, respectively. The study duration is 36 weeks.
This study tests that a low fat, plant-based (vegan) diet free of foods commonly identified as triggers improves mood, using the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), and the Beck Depression Inventory II (BDI-II).
