Pork Consumption Raises Kidney Stone Risk While Seafood Lowers It

A recent Chinese study found that increased consumption of pork correlates with a higher risk of developing kidney stones, while eating marine fish appears to reduce this risk.

The researchers analyzed data from 830 adult Chinese participants, including 299 individuals diagnosed with kidney stone disease and 531 without the condition. Participants completed detailed questionnaires about their dietary habits. The investigators then assessed the association between the intake of various types of meat and fish and the likelihood of kidney stone formation.

Results showed that individuals consuming large amounts of pork were over three times more likely to develop kidney stones compared to those who ate less pork. Conversely, participants who regularly consumed marine fish had an approximately 67% lower risk of kidney stone disease.

The study also indicated no confirmed link between the consumption of processed meats and kidney stone disease after adjusting for other influencing factors.

The researchers emphasized that their study is observational and does not establish a definitive causal relationship. However, they highlighted that the findings suggest the choice of animal protein sources may play a significant role in preventing kidney stones, warranting further investigation.

Previously, Professor Vigen Malkhasyan, a specialist in urology and oncology in Russia, recommended avoiding or reducing intake of certain oxalate-rich foods to prevent kidney stones. These include cocoa, black tea, chocolate (especially with high cocoa content), leafy vegetables such as spinach, sorrel, parsley, celery, green pepper, and beetroot, as well as fruits like figs and rhubarb, and nuts including almonds, walnuts, cashews, and hazelnuts, along with buckwheat.
