Since the main component found in kidney stones is calcium oxalate stones, it is necessary to eat less food high in calcium and oxalates in our diet. Common foods that are high in calcium include soy products such as tofu, soy milk, and dairy products like cow's milk and cheese, which should be consumed in moderation. Additionally, it is advisable to eat fewer foods high in oxalates, such as celery, spinach, strawberries, and chocolate. Moreover, if the stones are uric acid stones, it is important to consume less seafood, animal organs, beer, and other foods high in purines. It is best to drink more water every day and urinate frequently to dilute the urine, which can reduce the formation of stones.
