Kidney stones in the diet should pay attention to the following points:

One, pay attention to increase fluid intake, recommended daily fluid intake of more than four liters, so that the daily urine volume to maintain more than 2.0-2.5L.

Second, there is no need to limit the normal intake of calcium, the normal range and appropriate high-calcium diet has therapeutic value in preventing recurrence of urinary stones, but calcium supplementation outside of the diet may be detrimental to stone prevention.

Three, limit the dietary intake of oxalic acid, such as almonds, peanuts, beets and other oxalic acid-rich foods, of which spinach is high in oxalic acid, and patients with calcium oxalate stones should be careful to avoid eating spinach.

Four, limit sodium intake, high sodium diet will increase urinary calcium excretion.

Fifth, limit the excessive intake of protein, high protein diet will cause increased urinary calcium and urinary oxalate excretion, at the same time to reduce urinary citrate excretion, and reduce urinary pH, is one of the important risk factors for inducing the formation of calcium-containing stones in the urinary tract.

Sixth, increase the intake of fruits and vegetables, fruits and vegetables intake can dilute the stone-forming risk factors in the urine, but does not affect the concentration of urinary potassium and citrate.

seven, increase the diet of coarse grains and fiber, rice bran can reduce urinary calcium excretion, reduce the recurrence rate of urinary tract stones.

VIII, reduce the intake of vitamin C, vitamin C can form oxalic acid after conversion, easy to form calcium oxalate crystals.

Nine, limit the high purine diet, purine-rich foods such as sardines, anchovies, animal offal and so on.
