Evidence-based analysis — cod, fresh, Seafood
cod, fresh contains 98 milligrams of total purines per 100 grams of edible portion. This places it firmly in the moderate-purine category. The measurement includes all four purine bases — adenine, guanine, hypoxanthine, and xanthine — analyzed via HPLC method as established by Kaneko et al. (2014).

Japanese gout guidelines recommend keeping total daily dietary purine intake under 400 mg. A typical 150g serving of cod, fresh provides approximately 147 mg of purines — about 37% of the daily budget.
Of the four purine bases, hypoxanthine has the strongest uricogenic (uric acid-raising) effect. The ratio of hypoxanthine to total purines varies significantly by food type — animal tissues tend to have higher hypoxanthine ratios than plant foods, which may partially explain why animal purines are more strongly associated with gout attacks in epidemiological studies.
Dietary purines are natural compounds found in all foods, but concentrations vary enormously — from near-zero in eggs and dairy to over 500 mg/100g in dried fish and organ meats. The four purine bases (adenine, guanine, hypoxanthine, xanthine) are absorbed and metabolized to uric acid in the liver. However, not all purine bases are equal in their uricogenic effect — hypoxanthine has the strongest impact, and animal tissues tend to have higher hypoxanthine ratios than plant foods. This is one reason why epidemiology consistently shows that meat and seafood purines are more strongly associated with gout than vegetable purines.
The Japanese dietary guideline of 400 mg/day total purine intake is the most widely cited reference. Individual sensitivity varies: some patients flare at lower intakes, especially during acute episodes. The ACR 2020 gout guideline emphasizes purine restriction as a core dietary strategy alongside weight management and alcohol limitation.
