The basics
A low-purine diet is often prescribed for people with gout and Lesch-Nyhan Syndrome (a rare genetic disorder that occurs in 1 out of 100,000 people). People with diabetic nephropathy need to restrict proteins, a regimen that includes, but is not limited to, the restrictions imposed by a low-purine diet.
- Completely avoid very-high-purine foods such as anchovies, broth, and dried legumes.
- Eat very little high-purine foods such as some fish, poultry, or meat.
- Eat modest amounts of moderately high-purine foods such as oatmeal, soy, and spinach.
- Consult a healthcare professional before you make major changes to your diet. Avoiding foods high in purines can lead to a very-low-protein diet if you don’t substitute appropriately.
Best bets: Cereals, eggs, cheese, fruit, nuts, milk, and many vegetables
Why do people follow this diet?
In people who have gout, uric acid production in the body is increased while its elimination is reduced. The excess uric acid builds up in the bloodstream, is deposited in the small joints or soft tissues, and causes symptoms that resemble arthritis. Purines are compounds that are mainly found in animal protein and are metabolized to uric acid in the body. A high-purine diet, obesity, regular alcohol consumption, and diuretic therapy can all contribute to elevated uric acid levels in individuals with gout. Preliminary research suggests that insulin resistance may also play a role in the development of gout. A low-purine diet and medications—such as nonsteroidal anti-inflammatory drugs, corticosteroids, and allopurinol—are commonly used to treat gout. An effective diet is important in avoiding or reducing complications and lessening the expense of drug treatment. Restricting calorie intake and alcohol consumption, and losing weight (if overweight), can also reduce uric acid levels. It is important to drink plenty of fluids to increase uric acid excretion from the body. Alternative sources of protein should be included in a low-purine diet.
