Maintaining healthy kidneys is important in preventing the onset of other disorders related to the heart, immune and digestive systems. The key function of the kidneys is to filter blood of waste products and to maintain adequate blood volume, in order to facilitate the transport of oxygen, nutrients and hormones to other organs. Failed kidneys can cause toxins to accumulate in the body, which compromises blood quality and leads to lowered immune system functioning. According to the National Kidney and Urologic Diseases Information Clearinghouse, maintaining a healthy diet is significant in promoting good kidney health.
Cranberries, Strawberries and Blueberries
Free radicals are generated through normal metabolism or exposure to toxins in the environment. Antioxidants neutralize the free radicals to protect the body and promote healthy kidney functioning. Berries are foods containing high levels of oxygen radical absorbance capacity, or antioxidants. According to DaVita, a national kidney care provider, eating a diet rich in berries promotes kidney health and also provides protection to compromised kidneys. Cranberries help protect against bacteria causing bladder infections and blueberries reduce kidney inflammation. Raspberries inhibit tumor formation as well as prevent cell damage and strawberries prevent oxidative damage. Berries are also good sources of vitamin C for promoting immune system health, as well as fiber for regulating digestion.
Meat and Protein Sources
Protein is important for maintaining muscles, cell growth and healing the body. However, eating balanced portions from healthy sources of protein is essential in maintaining the kidneys, notes the National Kidney Foundation. Animal proteins contain higher content of purines, which increase the amount of uric acid stone formation in the kidneys. Choose proteins with lower fat content such as egg whites, fish and low-fat dairy. Egg whites offer a low phosphorus option for protein, which is important in people with compromised kidneys. MayoClinic.com indicates that elevated phosphorus in the kidneys leads to calcium deficiency and bone disease. Fish contains omega-3 fatty acids, a healthier source of fat, which reduces kidney inflammation and aids in lowering cholesterol. Salmon, mackerel and tuna are fish options to fulfill protein requirements while keeping the kidneys healthy.
Vegetables
Potassium is important for regulating heartbeat and maintaining muscles; however, too much potassium can prevent the kidneys from processing toxins adequately. Eating foods low in potassium is important for kidney health and certain vegetables supply low levels of potassium while also providing vitamins and fiber. Bell peppers, cabbage and cauliflower are rich in vitamin C, B6 and folate. Onions, squash and carrots also offer lower levels of phosphorus and potassium for maintaining kidney health, notes MayoClinic.com. If you have calcium oxalate kidney stones, avoid spinach and rhubarb to prevent further complications.
Beverages
The National Kidney and Urologic Diseases Information Clearinghouse indicates that drinking plenty of water daily is also important for maintaining healthy kidneys. On average, drinking 64 oz. of water daily is sufficient; however, this varies depending on activity level, weight and current medical conditions. Drinking one daily glass of orange juice or caffeinated beverages, such as tea or coffee, can prevent against kidney stone formation if used in moderation.
