Diet and nutrition play important roles in the management of kidney disease and overall health. If you are diagnosed with renal failure, or chronic kidney disease, you must monitor food intake because your kidneys do not effectively remove waste products. Your health care provider may recommend you modify your diet by controlling your protein intake. A registered dietitian can help you adjust your diet and recommend healthy food options.
Diet Significance
Check with your health care provider before starting any nutrient-restricted diet. She may recommend a low-protein diet to decrease the work load of your kidneys. A protein-controlled diet will also decrease waste in the blood that can build up due to poor kidney function. Following a low-protein renal diet will also promote healthy kidney function and delay progression of total renal failure, according to Drugs.com.
Protein Sources
Protein-rich foods include meat, poultry, fish, eggs and dairy products. Smaller amounts of protein are also found in beans, nuts and seeds. It is not necessary to completely avoid protein. Therefore, consuming several servings of protein-rich foods daily will ensure you get the minimal amount. A registered dietitian can help determine your exact protein requirements based on several factors such as age, weight and condition. To control protein intake, consume a variety of other foods such as fresh fruits, vegetables and starches such as cereal, rice, bread and pasta.
Nutrient Restrictions
In addition to protein, individuals with renal failure must also limit sodium intake. Elevated sodium levels in the body can lead to increased blood pressure and fluid retention, according to Jackson Siegelbaum Gastroenterology. Sodium is found in high concentrations in canned foods, processed meats, microwaveable dinners and condiments. At the grocery store, aim for foods that contain less than 100 mg of sodium per serving and are labeled "reduced-sodium". Other minerals such as phosphorus, calcium and potassium may also be limited if you have renal failure. A dietitian can give you a full list of acceptable foods based on your condition.
Considerations
A typical protein intake for a healthy individual ranges from 40 to 60 g of protein daily. Jackson Siegelbaum Gastroenterology suggests a low-protein diet that provides no more than 39 g of protein daily. Choose protein foods that are low in fat such as lean meats, skinless poultry and low-fat milk and cheese. Individuals with early stages of renal failure must also limit their fluid intake. Therefore, limit foods that contain high amounts of water such as soups, ice pops, gelatin, grapes, melons and lettuce.
Your protein recommendations may change if your disease progresses and you need to start dialysis.
