Foods to avoid for gout

Diets that are high in purines and high in protein have long been associated with an increased risk of gout, a type of arthritis. Uric acid levels can become elevated by eating a lot of purine-rich foods, by the overproduction of uric acid in the body, or if the kidneys do not eliminate excess uric acid. In the body, excess uric acid can precipitate out and form crystals in the joints, causing pain and inflammation.

Foods That Are Higher in Purines

Johns Hopkins lists the following foods as being higher in purines:

  • hearts
  • herring
  • mussels
  • yeast
  • smelt
  • sardines
  • sweetbreads

Foods Moderately High in Purines

  • anchovies
  • grouse
  • mutton
  • veal
  • bacon
  • liver
  • salmon
  • turkey
  • kidneys
  • partridge
  • trout
  • goose
  • haddock
  • pheasant
  • scallops

Interestingly, results from a well-known study led by Dr. Hyon K. Choi, reported in The New England Journal of Medicine, offered an interesting twist with regard to purines and gout. Choi's research team followed 47,150 men with no prior history of gout over a 12-year period. During that time, 730 men were diagnosed with gout. Study participants who consumed the highest amount of meat were 40% more likely to have gout than those who ate the least amount of meat. Study participants who ate the most seafood were 50% more likely to have gout.

In this specific study, though, not all purine-rich foods were associated with an increased risk of gout. There was no increased risk associated with a diet that included the following foods which are considered high in purines:

  • peas
  • beans
  • mushrooms
  • cauliflower
  • spinach

Choi's team also found that low-fat dairy products decrease the risk of gout, and overall protein intake had no effect. Ultimately, diets shown to be connected to gout are the same kinds of diet linked to cardiovascular disease.

Recommendations for Seafood Should Be Individualized

At this point, it may seem things are getting confusing. Isn't seafood typically recommended as part of a diet which is healthy for the heart? Yet research has revealed that there is a strong, undeniable link between seafood and gout. How does Choi reconcile what seems like conflicting information? He believes "recommendations for seafood should be individualized."

Sorting Out the Myths

More importantly, how does a person begin to sort the myths from the facts and decide what to buy at the grocery store? According to the University of Washington, Department of Orthopedics:

  • Obesity can be linked to high uric acid levels in the blood. People who are overweight should consult with their doctor to decide on a reasonable weight-loss program. Fasting or severe dieting can actually raise uric acid levels and cause gout to worsen.
  • Usually people can eat what they like within limits. People who have kidney stones due to uric acid may need to actually eliminate purine-rich foods from their diet because those foods can raise their uric acid level.
  • Consuming coffee and tea is not a problem, but alcohol can raise uric acid levels and provoke an episode of gout. Drinking at least 10 to 12 eight-ounce glasses of non-alcoholic fluids every day is recommended, especially for people with kidney stones, to help flush the uric acid crystals from the body.

Gout Medications

Medications for gout have reduced the need for dietary restrictions, but some dietary modifications can decrease the severity or frequency of gout attacks. Dietary modification may also be preferred by people who cannot tolerate gout medications.
