Patients with mild abnormal kidney function (elevated blood creatinine) should eat about 40 grams of protein daily, and should choose high-quality protein, i.e. protein rich in essential amino acids; eggs and dairy foods are preferred, one egg contains about 6 grams of protein, one bowl of milk (about 200 ml) contains about 6 grams of protein, 50 grams of lean meat contains about 8 grams of protein, chicken contains slightly more protein than lean meat, and fish slightly less. According to the above, it is not difficult to calculate the daily protein intake of a chronic kidney patient with azotemia. Plant-based protein should be consumed as little as possible because it contains fewer essential amino acids, so do not eat peanuts and beans and their products. If you eat less protein, you must eat more carbohydrates (such as sucrose, grape enamel) and fats (preferably eating vegetable oils) to supplement. In addition, attention should be paid to the supply of food rich in B vitamins and vitamin C-rich foods. As azotemia worsens, the amount of protein consumed should also be reduced. However, patients on dialysis do not need to restrict protein intake.
