13. Understanding the Impact of Purine-rich Fish on Kidneys

Fish is a nutritious food enjoyed by many, but certain types of fish, such as sardines, have a high purine content that can be potentially harmful to the kidneys when consumed in large quantities.
Purines present in sardines are converted into uric acid in the body, which can contribute to the formation of uric acid stones in the kidneys. This poses a risk, particularly for individuals prone to uric acid stone formation.

Studies conducted by the American Urological Association have linked purine intake to health problems. Higher consumption of purine-rich foods like sardines has been associated with hyperuricemia and hyperuricosuria in individuals without kidney stones. Additionally, purine-rich foods can stimulate the excretion of calcium oxalate, which can lead to the formation of calcium oxalate stones.
While sardines are an excellent source of essential omega-3 fatty acids, which are beneficial for overall health, it is advisable to limit their consumption to once or twice a week. Other purine-rich foods to be mindful of include anchovies, organ meats, bacon, scallops, shrimp, and baker's yeast. If you are at a higher risk of kidney problems, it is recommended to avoid these foods.
