Low-Purine Diet
IntroductionWhy this diet?Foods to avoidBest betsResourcesBibliographyA low-purine diet is often prescribed for individuals with gout andLesch-Nyhan Syndrome (a rare genetic disorder that occurs in 1/100,000people). People with diabetic nephropathy need to restrict proteins, aregimen that includes, but is not limited to, the restrictions imposed by alow-purine diet.
Why do people follow this diet?In people who have gout, uric acid production in the body is increased whileits elimination is reduced. The excess uric acid builds up in thebloodstream, is deposited in the small joints or soft tissues, and causessymptoms that resemble arthritis. Purine is a compound that is mainly foundin animal protein and is metabolized to uric acid in the body. A high-purinediet, obesity, regular alcohol consumption, and diuretic therapy can allcontribute to elevated uric acid levels in individuals with gout.Preliminary research suggests that insulin resistance may also play a rolein the development of gout. A low-purine diet and medications-such asnon-steroidal anti-inflammatory drugs, corticosteroids, and allopurinol-arecommonly used to treat gout. An effective diet is important to avoid orreduce complications and lessen the expense of drug treatment. Restrictingcalorie intake and alcohol consumption, and losing weight (if overweight),can also reduce uric acid levels. It is also important to drink plenty offluids to increase uric acid excretion from the body. Alternative sources ofprotein should be included in a low-purine diet.
What do I need to avoid?To avoid purine ask about ingredients at restaurants and others’ homes, andread food labels. The following list is not complete. Consult with ahealthcare professional before making any significant changes to your diet.
