Uric Acid Build Up
Organ meats, such as liver, heart and kidney, are very high in purines. Beef liver, for example, contains more than 286 mg of purine in 100 g and beef kidney contains more than 230 mg in an equal amount. In comparison, a low purine food such as cooked rice provides only 6 mg of purines per 100 g.
Certain types of fish and seafood are also very rich in purines. Oily fish, such as sardines, anchovies, salmon and mackerel are good examples. A 100 g serving of sardines contains almost 350 mg of purines and an equal amount of salmon provides 250 mg. Some shellfish such as clams are moderately rich in purines; 100 g of clams contains about 135 mg of purines.
Vegetables that are legumes are also purine-rich. Examples are black-eyed peas with 230 mg in a 100 g serving, lentils with 220 mg and split peas with 195 mg. Other beans, however, are much lower in purines. These include garbanzo beans with 56 mg purines in 100 g.
