Patients with calcium oxalate kidney stones (the most common type of kidney stone) should not overly restrict their diets to exclude calcium and oxalate, as many high-oxalate foods are very healthy, explains the National Kidney Foundation. Instead, the foundation recommends eating and drinking calcium and oxalate foods together during a meal, as these substances are less likely to bind to each other during the digestion process. Those with high amounts of calcium in the urine, should reduce their sodium intake, as increased sodium levels deplete the body of calcium, which is flushed out through the urine.

More generally, the National Kidney Foundation suggests consuming juices high in natural citrate and reducing sugar intake to prevent stone formation.
