Foods to Boost Kidney Function

The kidneys are paired organs that assist your body in waste removal, urine production and blood processing. When kidney function, medically called renal function, is affected by injuries, infections or kidney diseases, your body becomes unable to filter waste and blood products properly. Adjusting your daily regimen to include more kidney-friendly foods is important to boosting kidney functions, says the National Kidney and Urologic Diseases Information Clearinghouse.


Healthy Fats

Healthy fats, such as olive oil, canola oil, polyunsaturated vegetable oils, seeds and nuts provide dense amounts of calories and nutrients. Many people with kidney conditions struggle to maintain appropriate caloric levels. According to the National Kidney Foundation, poor caloric intake can put your body at risk for a weakened immune system and malnutrition. To combat this problem, incorporate healthy nuts, seeds and oils into snacks and daily meals regularly. Healthy fats also help your body absorb nutrients efficiently, which promotes overall body functioning. Consuming healthy fats with other foods such as fruits and vegetables can increase nutritional benefits.


Protein intake helps your body fight disease and repair body tissues. The National Kidney and Urologic Diseases Information Clearinghouse says that unhealthy kidneys often fail to properly remove protein from your waste, unlike healthy functioning kidneys. A reduced-protein diet can improve kidney health and reduce the workload on your kidneys. Protein is necessary for healing from kidney diseases and your overall health. Choose foods with modest protein amounts, such as rice or soy milk, low-protein nuts or pasta, legumes, leans meats, fish, poultry and egg whites. Adhere to modest portion sizes if you wish to consume protein-rich foods or if you have impaired kidneys. The National Kidney Foundation recommends that you view meats as a side dish instead of the main dish for optimal health benefits.

Vegetables and Fruits

Vegetables and fruits supply your body with powerful antioxidants, which prevents infection and supports a healthy immune system. Individuals with kidney disease or associated conditions should closely monitor their potassium levels to ensure that they remain in a healthy range, says the National Kidney and Urologic Diseases Information Clearinghouse. A low-potassium diet is recommended if your levels are excessive. Apples, berries, plums, cabbage, yellow squash and zucchini are low-potassium foods and nutrient rich. Incorporate an array of colorful vegetables and fruits into your diet for best nutritional wellness and benefits.
