Kidneys are paired organs each of us have that primarily regulate urination. They can become infected or develop various diseases. According to the National Kidney Foundation, 26 million Americans have a form of kidney disease and many others suffer from kidney-related illnesses and infections. A diet that includes certain foods is important for preventing and treating kidney disease.
Bell Peppers
Red and green bell peppers are low in potassium, an electolyte that often runs dangerously high in those with kidney disease, according to the National Kidney and Urologic Diseases Information Clearinghouse. They also provide valuable amounts of nutrients, such as Vitamins C, A and B6, all of which can help combat disease. Fresh cut bell peppers can be eaten as snacks or in mixed vegetable salads or slice and grill them lightly to add to stir-fry or as pizza topping. Other examples of low-potassium vegetables include alfalfa sprouts, cabbage, cooked carrots, corn, cauliflower, kale, peas and onions.
Berries
Berries, such as blueberries, raspberries and strawberries contain powerful anti-oxidants, which may help prevent and eliminate disease. They may have a potential anti-inflammatory effect, which is helpful when the kidneys or other body parts bloat or swell. Berries, too, are low in potassium and since they are high in nutrients they can be enjoyed as a regular part of the diet. It is recommended to incorporate them into meals regularly and seek a variety of colors and types for the best nutritional benefits.
Healthy Fats
Healthy fats are important for those with kidney disease as many individuals experience unhealthy weight loss. The National Kidney Foundation suggests adding foods that are dense in calories, such as nuts, peanut butter, vegetable oil or creamer, for those who need to gain weight. If a person's weight is within a healthy range, modest amounts of healthy fat-based foods, or approximately one serving at each meal, will suffice.
Lean Protein
People with kidney disease or who are undergoing dialysis will likely have to restrict their protein intake. Protein is important for health and healing, however, so it should not be eliminated. If a doctor has suggested that a patient adhere to a low-protein or protein-reduced diet, she should choose a small amount of high quality protein at each meal. For example, a meal could include 1 to 2 oz. of fish or poultry, 1/2 cup milk or 1/2 cup legumes. As a meal-planning tool, the National Kidney Foundation suggests viewing protein as a side dish and carbohydrate and vegetables the main course.
Carbohydrates
Carbohydrates provide glucose, or energy, which the body requires for proper function and wellness. Kidney disease is one of the few disorders that may require reduced intake of whole grain carbohydrates due to their high phosphorus content. If a patient has been told to avoid phosphorus, he should stick to white breads, cereals, pasta and rice. If struggling to keep weight up to a healthy level, simple sugars, such as candy, frosting and other sweets may also prove beneficial. If a person has not been advised to increase body weight or avoid phosphorous whole grain, carbohydrates are preferable. In either case, the National Kidney foundation recommends six to 11 servings of carbohydrate foods every day.
