Whether or not a person with kidney stones can eat tomatoes depends on the type of stones. If it is oxalate stones, it is better to choose to eat less or no tomatoes, while there is no problem to eat tomatoes for other types of stones. Kidney stones include calcium phosphate stones, urate stones and oxalate stones. If the stone type is oxalate stone, you need to limit the intake of tomato, otherwise it may increase the incidence. Because tomatoes are high in vitamin C, excessive intake can lead to the formation of oxalic acid in the body, which in turn promotes the development of oxalate stones. But if it is other types of stones, such as calcium phosphate stones or urate stones, eating tomatoes is usually not affected. Patients are advised to visit regular hospitals for timely treatment. In terms of diet, it is important to ensure balanced nutrition as well as emphasize on disease management; it is also important to drink plenty of warm water and exercise actively for early recovery.
