Protein Restriction Guidelines
When the human body metabolizes animal proteins, several promoters of urinary stone formation are produced. High protein intake can increase urinary levels of calcium and uric acid, as well as decrease urinary citrate. Therefore, we recommend that our patients with a history of stones restrict the amount of protein in their diets. Specifically, you should not exceed more than 80 grams of protein per day.
