1, hypopurine. Patients with kidney calculi's disease should focus on low-purine foods in their daily diet, because foods containing purine will lead to imbalance of pH in the body. Causing oxalate deposition will lead to more serious lithiasis. Eating some foods with low purine can prevent stones from getting bigger. Common foods are melons, fruits, eggs, cereals and vegetables, such as rice, millet, potatoes, watermelons, persimmons, milk and yogurt.

2, low calcium. Kidney calculi patients should also pay attention to low-calcium diet in their daily diet, because a large intake of calcium-containing food will lead to more serious stones. The common calcium content of beef, pork liver, lean meat and chickens and ducks is relatively low. When eating a low-calcium diet, patients should also pay attention to avoid calcium deficiency caused by long-term intake, such as osteoporosis, physical weakness, easy cramping, leg weakness and so on.

The most important thing for kidney calculi patients in their daily diet is to drink plenty of water, which can reduce the concentration of oxalic acid and calcium ions in the body and avoid the formation of multiple stones.
