Seafood is low in oxalate across the board, with most fish measuring under 5 mg per serving. Like meat, the consideration is the animal protein content — and for some patients, the purine load of certain fish, which matters for uric acid stones rather than calcium oxalate stones. Fatty fish add a genuine benefit in omega-3s. The practical place of seafood in a stone diet is as a portioned protein source: low oxalate, moderate protein, and a healthy fat profile.
