People with rheumatoid arthritis often find relief by eating fish, colorful produce, whole grains and olive oil, according to WebMD. These foods are all part of a typical Mediterranean diet.
Adding fish to the diet of someone suffering from arthritis helps because the polyunsaturated fats in fish, which include omega-3 fatty acids, suppress cytokines that cause inflammation, explains WebMD. Colorful produce such as blueberries, squash, carrots and tomatoes helps those who suffer from arthritis because they contain a lot of antioxidants. These antioxidants also fight inflammation, which is the main cause of pain in arthritic joints.
Whole grains such as oatmeal, barley and brown rice are also important to add to the diet to reduce discomfort due to arthritis, according to WebMD. These whole grains help to lower the levels of C-reactive protein in the body, one of the main markers of inflammation. In people suffering from arthritis, this protein level rises during flare ups, but whole grains help to combat this. Adding olive oil to the diet is also important for people suffering from arthritis, as it helps the body to stop producing the chemicals that bring on inflammation. When there is no inflammation present, those with arthritis don't have pain.
