Walnuts do not cure kidney stones, but rather walnuts contain more oxalic acid, long-term, large intake can increase the body’s oxalic acid content, which can easily lead to the increase in stone size, or the formation of new stones. When suffering from kidney stones, you should reduce the consumption of walnuts and other nuts, including pine nuts, hazelnuts, etc. The majority of kidney stones are calcium oxalate stones, calcium phosphate stones, a small number of xanthine stones, infected stones, cystine stones, etc. Therefore, the intake of purines and oxalic acid should be reduced in daily life to prevent the formation of stones, and drinking more water to maintain a dilute urine is also an important measure to prevent stones. Various kinds of nuts, spinach, celery, chocolate, cocoa, prunes, strawberries, etc. are rich in oxalic acid in daily life and are more likely to suffer from kidney stones after a long time and large intake. Various seafood products, animal offal and long time and large amount of alcohol consumption can lead to abnormal metabolism of uric acid level and easily lead to the formation of xanthine stones.
