If there were a "safest fruit for kidney stones" award, bananas would be a strong contender. One medium banana has about 6 mg of oxalate — well under the 25 mg safe threshold. They're also cheap, available year-round in every grocery store, portable without packaging, and require zero preparation. For anyone building a kidney-stone-safe diet from scratch, bananas belong near the top of the shopping list. The potassium content is a bonus: potassium citrate is sometimes prescribed for stone prevention because it alkalizes urine, and while a banana won't replace medication, the dietary potassium is directionally helpful. If you're looking for a grab-and-go food with zero oxalate anxiety, this is it. Just don't fry them or coat them in chocolate — the banana itself is innocent.
