Determination of total purine and purine base content of 80 food products to aid nutritional therapy for gout and hyperuricemia

The aim of this work is to facilitate the nutritional therapy of gout and hyperuricemia. In Japan, patients with gout or hyperuricemia are recommended to consume less than 400 mg of dietary purines per day. When receiving nutritional therapy for gout or hyperuricemia, purine-rich foods (200 mg/100 g) should be eaten in even lower quantities. The purine content of foods reported in this study are as follows: noodles, 0.6-12.1 mg/100 g; bread, 4.4 mg/100 g; peas or seeds, 19.6-67.1 mg/100 g; dairy, 0.0-1.4 mg/100 g; Japanese vegetables, 0.9-47.1 mg/100 g; seasonings, 0.7-847.1 mg/100 g; meat or fish, 19.0-385.4 mg/100 g; fish milt, 375.4-559.8 mg/100 g; and supplements, 81.9-516.0 mg/100 g. Foods containing very large amounts of purine (300 mg/100 g) included anchovy, cutlassfish (hairtail), cod milt, globefish milt, dried Chinese soup stock, dried yeast, a
