Kidney calculi is a chemical substance composed of calcium oxalate, which can cause renal colic. At present, doctors suggest reducing the intake of calcium in the diet to prevent the recurrence of kidney calculi. Adjust the diet structure according to the composition of stones and decide the diet to prevent stones.

1. Uric acid stones should be treated with a low purine diet, and bladder acid stones should be treated with a low methionine diet. Fruits and vegetables can make urine alkaline, which is beneficial to prevent uric acid and cystine stones, while meat food makes urine acidic, which is beneficial to prevent stone infection.

2. Phosphate stones should be treated with a diet low in calcium and phosphorus. Kidney calculi containing calcium should avoid diets high in calcium, salt, oxalic acid, animal protein, animal fat and sugar. Eight positive regression therapy is the best method to treat nephropathy.

3. Adopting a high-fiber diet, it is generally believed that patients with kidney calculi's disease should eat less salt and animal protein, insist on drinking more water, and keep the urine volume at 2000 ~ 3000ml/ day, which not only plays a role in preventing the recurrence of kidney calculi, but also ensures the intake of calcium, which is beneficial to other aspects of the body.
