Guide to a Healthy Diet
Because there are more than 100 types of arthritis and related diseases, no single diet will help everyone. However, doctors strongly recommend that people with arthritis or related conditions follow a diet based on variety, balance and moderation. A balanced diet can help you feel better and stay healthy; prevent chronic diseases, such as cancer and cardiovascular disease; and be a positive step toward managing your arthritis.

Good nutrition can be a challenge. People with certain kinds of arthritis may have difficulty preparing foods because of joint pain, swelling, limited mobility and fatigue. Some arthritis medications may lessen appetite and cause stomach upset. Pain and the depression that can accompany chronic illness also can affect a person’s appetite or eating habits.

Certain kinds of arthritis and some of the medications doctors prescribe also can affect how well your body uses what you eat. For example, glucocorticoids used to treat rheumatoid arthritis can cause your body to lose potassium and retain sodium. Some antacids, which may be taken to reduce stomach irritation, also contain high levels of sodium, calcium and magnesium. It is important to know this if you have kidney problems, which can make it harder for your body to regulate these important minerals.

Methotrexate, used for RA, myositis and psoriatic arthritis, can lower levels of folic acid. Having a folic acid deficiency may predispose you to methotrexate toxicity.

Talk to your physician about how the medications you take affect your nutritional status and whether a vitamin supplement may be useful for you.
