Kidney stone patients need to pay attention to the diet: 1. Increase calcium intake: research shows that enough calcium will be combined with oxalic acid and excreted by the feces, thus reducing the absorption of calcium by the intestinal tract, of course, will reduce the chance of stone production. Therefore, drinking more milk will not increase the number of stones, but help to reduce the chance of stones.　　2. Reduce the intake of oxalic acid: Spinach, tea and other foods containing more oxalic acid should be reduced.　　3. Reduce sodium intake: Eat a light diet and minimize the consumption of canned and processed foods. Eat more foods containing potassium, such as bananas and other foods.　　4. Reduce meat intake: Reducing the intake of animal protein can reduce the chance of stone formation.　　5. Drink more water and exercise: Drinking more water can speed up the metabolism of salts in the urine, so drink at least 3,000 C.C of water a day. More exercise can reduce bone calcium loss, which in turn reduces the production of stones.
