Vitamin C is one of the nutrients most responsible for the health of collagen, a major component of cartilage. In addition, research suggests that people who eat a diet low in vitamin C may have a greater risk of developing some kinds of arthritis. For those reasons, it is important to make vitamin C-rich foods — such as guava, bell peppers (yellow, red, orange, and green), oranges, grapefruits, strawberries, pineapple, broccoli, kidney beans, kiwi, and cauliflower — a part of your daily diet. (High-dose vitamin C supplements can actually be harmful for osteoarthritis sufferers, so talk to your doctor about what's right for you.)
If you suffer from arthritis, ease painful symptoms by eating plenty of foods and ingredients that naturally reduce inflammation.
