![]() Purine content in alcoholic drinks, seasonings and supplements Table 4: Purine content in seafoods (fish and crustaceans, fresh and canned), and vegetables (legumes). Table 3: Total purine content in raw and cooked foods. Purine sourcesĪccording to a study that compared free and total purine bases content in meat products (steak, beef liver and haddock fillets) before and after cooking, cooking appears to increase the level of free and total purine bases in a diet. Table 2: Purine content in chicken, pork, lamb, and beef parts. Purine content also varies depending on the type of meat cuts or organ. ![]() Table 1: High or low purine food sources. Generally, there is a positive association between protein and purine content in diet. Meat and meat products have high total purine content, where as cereal foods contain low purine content. Total purine content is based on the sum of all the four purine bases. ![]() In the following tables are estimates of total purine content in a variety of food items, presented in descending order. Total purine content (mg per 100 gram food) Food Purine Content Groups and Gout RiskĪccording to a Japanese study, foods can be classified into five groups based on the total purine content and level of risk to hyperuricemia and gout. The Japanese Society of Gout and Nucleic Acid Metabolism, to prevent an abnormal high level of uric acid in blood (hyperuricemia) and gout, recommends to keep purine consumption to under 400mg per day.Īccording to the Japanese Society of Gout, a blood urate level below 7mg/dL is considered to be normal and above it, hyperuricemia and gout risk. The Dietary Guidelines for Americans has no recommended daily intake for purines or uric acid. A recent study also found a positive association between fructose (a type of sugar found in fruits) and sweetened beverages and gout.Īccording to some studies, a purine-free diet decreases blood uric acid level, on average, from 1.0 to 1.2 mg/100 ml whereas, consumption of 4 g of ribonucleic acid (RNA), purine, per day, increases blood uric acid level from 1.5 to 2.0 mg /100 ml. Moderate intake of purine-rich vegetables or protein was not associated with an increased risk of gout. Whereas higher level of consumption of dairy products, especially skimmed types, was associated with a reduced risk of gout. Gout is a form of arthritis caused by accumulation of uric acid crystals in joints, such as in the big toe.Ī 12-year study that followed eating habits and gout incidence in a large number of men found that eating purine rich food, such as meat and seafood, was associated with high risk of gout. When it accumulates to a high level in the blood, hyperuricemia, however, it can cause gout, and other health problems. Uric acid is an antioxidant and has beneficial effects, such as as a free-radical scavenger. Purine metabolism, breakdown of purine molecules, in the liver, produces uric acid. They are essential for life and are found in all plant and animal cells. The first four purines, in combination with pyramidines, make up the genetic codes DNA and RNA, and energy molecules, such as ATP, GTP and coenzyme A. Purines are organic molecules that include nucleotides (adenine, guanine, hypoxanthine, xanthine), and caffeine.
