Can patients with kidney stones eat persimmons?

Generally, patients with kidney stones can eat persimmons, but in moderation. Detailed analysis is as follows:

Persimmons are low in purines and oxalates. Moderate consumption generally does not directly cause stone formation or worsen existing conditions. They also provide essential nutrients such as vitamins and dietary fiber, which help maintain normal body metabolism. However, it's important to choose fully ripe persimmons, as unripe ones contain higher levels of tannic acid, which may burden the gastrointestinal system. Additionally, each serving should not be excessive. It is recommended to consume half to one persimmon at a time to avoid excessive sugar intake.

Patients should also pay attention to the following when consuming persimmons: avoid eating them on an empty stomach. In an empty stomach state, tannic acid in persimmons can easily combine with stomach acid and calcium in the body, possibly forming indigestible substances. Although these substances are not directly equivalent to stone components, they may still affect body metabolism. Persimmons should not be consumed in large quantities together with high-calcium foods to reduce the chance of tannic acid binding with calcium. If the patient's stone type is calcium oxalate stones or if they are experiencing an acute stone episode, it is recommended to consult a physician before deciding whether to consume persimmons. If abdominal pain, bloating, or other discomfort occurs after consumption, intake should be stopped immediately and medical advice sought.
