Studies at Tufts University have shown that people with rheumatoid arthritis have an increased need for vitamins B6 and folate (also a B vitamin). Because of the process of inflammation, it appears that these nutrients are depleted at a faster rate than in people without the disease. You can find B vitamins in foods such as baked potatoes, bananas, poultry, beef, fish and vitamin supplements. Folate can be found in green leafy vegetables, citrus fruits, and whole grain foods such as bread, pasta and brans.
