The kidneys are paired organs that help the body process blood, aid in production of urine and help the body rid itself of waste. When kidney function, also called "renal function," is dampened by kidney diseases, infections or injuries, the body can't filter blood and waste products properly. According to the National Kidney and Urologic Diseases Information Clearinghouse, a dietary lifestyle that supports kidney function is crucial for those diagnosed with or at risk for kidney disease.
Protein
Protein intake helps the body repair bodily tissues and fight diseases. According to the National Kidney and Urologic Diseases Information Clearinghouse, unhealthy kidneys often fail to remove protein from waste the way properly functioning kidneys do. A reduced-protein diet can lessen the workload of the kidneys and improve kidney health. Protein is necessary for health and healing from kidney diseases, however, so choosing foods that provide modest amounts of protein, such as soy or rice milk, legumes, low-protein pasta or nuts rather than protein-rich foods, such as meat, eggs and poultry, most often is a useful dietary technique. If you have impaired kidneys and wish to consume protein-rich foods, adhere to modest portion sizes. The National Kidney Foundation suggests viewing meats as a side dish rather than the main dish for best results.
Healthful Fats
Healthful fats, such as polyunsaturated vegetable oils, olive oil, canola oil, nuts and seeds, provide nutrients and dense amounts of calories. According to the National Kidney Foundation, many individuals with kidney disease struggle to keep caloric intake up to appropriate levels. Poor caloric intake can put the body at risk for malnutrition and a weakened immune system. If proper caloric intake is a challenge for you, incorporate healthful oils, nuts and seeds into meals and snacks regularly. Dietary fats also enhance nutrient-absorption in the body. By consuming healthful fats with other healthful foods, such as vegetables, nutritional benefits can increase.
Fruits and Vegetables
Fruits and vegetables supply the body with nutrients such as antioxidants, which support a healthy immune system and prevent disease. According to the National Kidney and Urologic Diseases Information Clearinghouse, individuals with renal diseases should monitor potassium levels in their blood to ensure that they remain within a healthful range. If levels of potassium are excessive, a low-potassium diet is recommended. Apples, cranberry juice, canned fruit, berries, plums, cabbage, mustard greens and brocolli are nutrient-rich, low in potassium foods. Incorporate a variety of acceptable fruits and vegetables into your diet regularly for best nutritional and wellness benefits.
