    Protein, especially animal protein, is rich in phosphorus, and also contains glycine and hydroxyproline as raw materials for oxalic acid. A high protein diet can generally increase the urine excretion of phosphorus, calcium, oxalic acid and uric acid, which can increase by 20%—40&# xFF05;, while urinary citrate excretion is reduced by 27%, increasing the risk of urinary stone formation by a factor of 2.5. Healthy people's daily protein supply is 1g/kg, chronic kidney patients 0.6-0.8g/kg, mainly high-quality protein.
