Vitamin C
In a study in Arthritis & Rheumatism, osteoarthritis sufferers who consumed the most vitamin C (an average of 500 milligrams per day) reported less knee pain and were three times less likely to experience a progression of their symptoms over seven to ten years than those consuming the least—possibly due to the vitamin's protective effect on cartilage and bone. Try snacking on C-rich foods like guavas and red peppers.
