In addition, we should take enough protein: the daily intake of protein is 1.2g/kg, and we should pay attention to the quality of protein. More than two-thirds of patients should be given high-quality biological protein, such as egg white, milk, lean meat, fish and so on. Limit salt intake: Reducing salt intake can prevent water retention, hypertension, congestive heart failure and dialysis complications. The intake of salt is generally 3-5g per day, and high-sodium foods such as pickles, salted eggs, sauces and various pickled products should also be avoided.
