Kidney Stone Prevention: Low Animal Protein (Meat) Recommendations
Jun 3, 2026
The below recommendations are not applicable to all patients and all stone types. Please consult with your provider to determine if these suggested dietary adjustments are applicable to you and your stone.
Why does animal protein matter?
- Eating meat, including poultry and fish, adds acid to your body. This can change the pH of your urine (pee).
- Animal proteins increase uric acid in your body. Uric acid is a waste product that’s created when your body breaks down chemicals called purines in food and drinks. Too much uric acid in the body can lead to kidney stones.
How much animal protein should I eat?
- Try to eat less animal protein during the week or eat smaller portions.
How can I eat less animal protein?
- Make 2 or more days each week “non-meat” days. You can use dairy and eat plant-based protein foods like beans.
- Only eat 1 serving of meat, fish, poultry or seafood each day.
- Keep portion sizes of meat, fish, poultry, or seafood to no more than 1/4 of your plate (or 3 to 4 ounces by weight).
- Do not eat organ meats, waterfowl, game meats, and certain types of seafood (anchovies, sardines, herring). These are high in purines.
