Control your inflammation
In the case of rheumatoid arthritis and psoriatic arthritis, for example, “control[ling] inflammation is the goal of treatment,” says Dr. Askanase. Adhering to a diet that’s rich in inflammation-fighting foods may also help. These include oily fish that are high in omega-3 fatty acids (such as salmon), dark leafy greens, colorful veggies (think: tomatoes, peppers, and beets), low-fat dairy products, and whole grains.
