Consuming a chronic renal failure diet that includes the correct proportion of all nutrients can do wonders to maintain the health of your kidneys. Avoiding fruit juices, dry fruits, as well as foods that are high in phosphorus is advised when the organ isn't functioning as it should. Patients who are suffering should carefully keep track of their salt intake and avoid eating packaged food which can inadvertently increase their salt intake and damage the organ. Certain chronic diseases, such as high blood pressure and diabetes, can cause harm to the organ. If you manage these problems correctly, these issues can be repaired and kept in check.
