Cranberries are very low in oxalate at 2 mg per half-cup. They're also famous for urinary tract health, though the evidence for UTI prevention is stronger than for kidney stone prevention — these are different mechanisms. Fresh cranberries are intensely tart and usually need sweetening. Dried cranberries often have added sugar. Cranberry juice cocktail is mostly sugar with a little cranberry. From an oxalate perspective, all forms are safe. The sugar content of commercial cranberry products is the thing to watch.
