Salmon checks every box for kidney stone patients: near-zero oxalate, high-quality protein, and omega-3 fatty acids that reduce systemic inflammation. Wild salmon has a slightly better fat profile than farmed, but both are excellent choices. Among animal proteins, salmon arguably offers the best overall profile for stone formers because the anti-inflammatory omega-3s may provide secondary benefits beyond just being oxalate-free. Keep portions to 3-4 ounces — the animal protein guideline still applies. If you eat fish twice a week and make one of those meals salmon, you're doing well. Bake it, grill it, or pan-sear it. Avoid heavy cream sauces that add sodium, but a squeeze of lemon (citrate bonus) and some herbs is perfect.
