If you are looking for a tasty healthy treat, reach for an orange – or a tall glass of orange juice. Why? Recent research has shown the importance of vitamin C and other antioxidants in reducing the risk of osteoarthritis and its progression. Another bonus: oranges and other citrus fruits are good sources of folic acid, which can help alleviate the side effects of the arthritis drug methotrexate and reduce the risk of cardiovascular disease in women who have lupus.
