If you want to improve your quality of life, it is highly recommended that you adhere to a disease specific diet which will help you prolong the life of your kidneys and avoid progression to more advanced kidney disease. A healthy kidney diet includes three major aspects that are of paramount importance:
• Sodium. Sodium is not just salt; it is one of the body's main electrolytes, so the excessive presence of this makes your kidneys and consequently cardio-vascular system work much harder. Tracking sodium levels is very important in this case, so try to avoid salty food.
• Potassium. This is another very important electrolyte; diseased kidneys are unable to remove potassium from the body effectively leading to high blood levels that can be life threatening. Examples of foods high in potassium: avocados, beans, fish, citrus juices, bananas, potatoes, and spinach.
• Phosphorus. This electrolyte is removed mainly by your kidneys. If not removed effectively, elevated levels will lead to serious problems such as cardiovascular disease. Example of foods high in phosphorus: beef, hard cheeses, junk food, soda, milk and dairy products, certain beans, and canned fish.
Good nutrition plays a vital role in the maintenance of adequate levels of sodium, potassium, and phosphorus to assist the optimal functioning of your kidneys especially when you have CKD depending on the stage of the disease. However, you have to specify your diet with your doctor in this regard, as different people may have different dietary restrictions. Remember to visit your doctor to further discuss specific dietary recommendations to ensure your kidneys (and you) remain happy and healthy.
