The diet requirement is complicated as the patient has to maintain intake of various nutrients in fixed and appropriate proportions depending on the stage of kidney disease – aiding in treatment of renal failure.
You need to understand and to cater the need of calories from different foods that are not high in protein and sodium to help you either to maintain or gain weight.
Doctors advise controlled intake of proteins in renal failure, the reason being that the wastes produced in the blood can be minimized and help your kidneys function longer.
Sodium (salt) is associated with increased blood pressure, and in a diet for kidney failure you will be encouraged to limit your intake. You can try spice and herbs – fresh and dried and lemon juice instead of using salt.
