Coconut milk has about 2 mg per cup. The one watchpoint: coconut is high in saturated fat, which is a cardiovascular consideration separate from kidney stones. For oxalate, coconut products are safe. Use coconut milk in curries, shredded coconut in baking, and coconut oil for cooking without oxalate concern.
