Adhering to a low-purine diet helps limit uric acid production and manage the symptoms of gout -- a painful condition occurring when uric acid builds up in your joints. On a low-purine or gout diet, you'll avoid foods high in purines -- naturally-occurring substance found in many foods, particularly of animal origin. Your health care provider may recommend seeing a registered dietitian to help you implement this type of diet.
High Purine Foods to Avoid
A low-purine diet typically restricts you to about 100 to 150 milligrams of purines per day. Foods with 100 to 1,000 milligrams of purine per 3-ounce serving include bacon, organ meats, yeast, yeast extracts, venison, minced meat and meat extracts. Certain fish are also very high in purines; these include anchovies, codfish, herring, haddock, mackerel and sardines. Other types of seafood you must avoid on a low-purine diet include shrimp, scallops and mussels.
Foods to Include
It's safe for you to eat plenty of fruits that supply fiber as well as lots of nutrients. You can also eat eggs and low-fat dairy foods. Most vegetables are low in purines. Some vegetables, such as asparagus, spinach, mushrooms and cauliflower contain a moderate amount of purines. You may need to limit the serving size of these moderate-purine foods. For example, limit oats to no more than six ounces per day, recommends the NYU Langone Medical Center. Limit moderate-purine vegetables to no more than one-half cup per day. It's also recommended that you eat enriched breads, rice, noodles, pasta and potatoes, according to the NYU Langone Medical Center.
An example of breakfast on a low-purine diet includes 1/2 cup of low-fat yogurt, one slice of whole-wheat toast and 1 cup of mixed fruit. For lunch, you might have a chicken sandwich, using 3 ounces of lean chicken breast, two slices of enriched bread and a side salad with reduced-fat dressing. A typical dinner on a low-purine diet might include 3 ounces of salmon, 1 cup of broccoli, one-half-cup of rice and a small salad with fat-free dressing.
In addition to avoiding high purine foods, you need to avoid or limit alcohol since it increases uric acid production. Limit meat to 3 ounces per meal, recommends the University of Pennsylvania Medical Center. Drink plenty of fluids, at least eight to 12 cups each day, since fluids help dilute uric acid in your blood. Limit high-fat foods and opt for lower-fat alternatives. For example, choose low-free dairy products like fat-free cottage cheese and low-fat yogurt. If you lose weight, do so slowly since weight loss increases uric acid levels.
