In acute renal failure, if the urine output is normal or not very strong, there is basically no special restriction on diet.

Another is the diet of chronic renal failure, chronic renal failure, if it is not combined with other diseases, generally need a high quality low protein diet. What is meant by high quality protein, high quality protein refers to animal protein, such as lean meat, eggs, milk. High quality low protein is less quality protein, can not eat, but can not eat too much, every day to eat two or two lean meat, a packet of milk, an egg, something from the animal to eat these can.
