Kidney calculi patients should eat more fruits, such as apples, watermelons, oranges, bananas, grapefruit and oranges. Among the reasons for the formation of kidney calculi, diet is a very important reason, that is, eating too much food is easy to form some kind of stones. For example, in coastal areas, people like to eat seafood and animal offal, or some people like to drink beer, so people are prone to form uric acid stones; People who usually like to eat meat or eggs and drink milk are prone to cystine stones; Some people like to eat snacks, such as strawberries, chestnuts and pine nuts. These people are prone to form oxalate stones.

However, the fruits such as apples and watermelons mentioned just now do not belong to these three foods. Even if it is eaten for a long time, it has no adverse effects on the body. They are not only difficult to form stones, but also contain more water, which has diuretic effect and can promote the discharge of stones. For these three kinds of foods that can form stones, it is suggested that kidney calculi patients should eat less at ordinary times.
