Patients with kidney stones do not have particular dietary prohibitions, but it is generally advised to avoid long-term, large consumption of foods that promote stone growth. For instance, one should not regularly consume foods high in calcium, such as dairy products like milk and cheese, or soy products like tofu, soy milk, etc. These foods should be consumed in smaller quantities. Also, it is advisable to eat less food high in oxalates, such as celery, spinach, and others. If the stones are uric acid stones, it is recommended to reduce the intake of foods high in purines, such as seafood, as well as beer, beverages, and animal offal. These foods have high purine content and should be limited to prevent or reduce the formation of uric acid stones.
