Consuming plant-based meat alternatives instead of animal meat reduces dietary acid load, evidenced by lower urinary excretion of sulfate, ammonium, phosphorus, and urea nitrogen, and higher urine pH and citrate levels in healthy adults.

If you are concerned about kidney health or urinary stone risk, switching from animal meat to plant-based meat alternatives (consuming at least 2 servings daily) can help reduce the acid load on your kidneys. This shift lowers harmful urinary acids and increases protective citrate, potentially offering benefits similar to eating more vegetables, without requiring a complete change in taste preferences.
