Macadamia nuts are the standout winner among nuts for kidney stone patients. Very low oxalate (among the lowest of all tree nuts), rich in healthy monounsaturated fats, and with a buttery flavor that makes them satisfying in small portions. If you're a nut lover who had to give up almonds, macadamias are your replacement. They're expensive, but you don't need many — a small handful is filling. Use them in trail mix, on salads, or as a standalone snack.
