  • low-purine diet to reduce urinary excretion of uric acid (shellfish, mushrooms, and


organ meats), limit protein, Allopurinol.



  • Avoid food contain oxylate: spinach, strawberries, chocolate, tea, peanuts, and wheat


bran


Historically, patients with calcium-based renal stones were advised to restrict calcium
in their diet. However, recent evidence has questioned the advisability of this practice,


except for patients with type II absorptive hypercalciuria (half of all patients with


calcium stones), in whom stones are clearly due to excess dietary calcium.


It is thought that a high-protein diet is associated with increased urinary excretion of


calcium and uric acid, thereby causing a supersaturation of these substances in the


urine. Similarly, a high sodium intake has been shown in some studies to increase the


amount of calcium in the urine.


Foods high in purine (shellfish, anchovies, asparagus, mushrooms, and organ meats)


are avoided
