What fruits can't you eat if you have kidney stones?

Patients with kidney stones should avoid eating fruits rich in oxalic acid, such as persimmons, grapes, strawberries, etc., because oxalic acid can easily combine with calcium to form stones, aggravating the condition.

In detail, stone disease includes kidney stones, gallstones, etc., which are mainly related to mineral metabolism disorders in the body. Some fruits have high oxalic acid content. After entering the body, these oxalic acids will combine with calcium and deposit, increasing the risk of stone formation. For example, fruits such as strawberries and grapes contain high oxalic acid and are prone to form calcium oxalate stones; the tannic acid in persimmons may also aggravate the deposition of kidney stones. For patients with gallstones, high-fat, high-cholesterol fruits such as coconuts are not recommended because they may stimulate bile secretion and aggravate stone symptoms.

Patients should pay attention to choosing fruits that are low in oxalate or beneficial to stone disease, such as apples and pears, and ensure adequate daily water intake to help dilute urine and reduce stone formation. At the same time, they should adjust their diet according to the doctor's advice and receive relevant treatment when necessary, such as drug-dissolving stones or surgical lithotripsy.
