A. This statement is not correct. Limiting calcium intake is not recommended for preventing calcium oxalate stones. In fact, adequate dietary calcium can help reduce the risk of stone formation.

B. This statement is not correct. Foods high in oxalate, such as spinach and nuts, should be limited to prevent calcium oxalate stones.
