The kidneys are important organs that carry out functions essential for health. They process blood constantly, removing waste products and extra water which are stored in urine until it is excreted. The kidneys also help maintain proper blood pressure by producing a hormone called renin that regulates the total volume of blood. The kidneys produce two other hormones -- one that stimulates production of red blood cells and another that is important for healthy bones. There are several strategies that are helpful in keeping the kidneys functioning normally and avoiding kidney disease. Consult a doctor before making major dietary changes to determine an appropriate regimen.
Increase Fluid Intake
Drinking lots of fluids is very healthy for the kidneys. It helps flush toxins and wastes out of the body and is protective against kidney stones, according to the National Kidney and Urologic Diseases Clearinghouse. The website states that the amount of fluid needed by a person depends on several factors, including the environmental temperature and a person's exercise level. In general, 6 to 8 glasses of water daily is a healthy amount. The Clearinghouse indicates that citrus juices are also good choices, especially for anyone who has ever had kidney stones. Their citrate content helps inhibit crystal formation in urine.
Eat Cranberries
Urinary tract infections are very common, especially among women. The National Center for Complementary and Alternative Medicine recommends consuming cranberries and cranberry juice to maintain kidney health and prevent infection. It states that the way in which cranberries help the kidneys is not fully understood but may involve compounds in the berries that prevent bacteria from attaching to lining cells in the urinary tract. It also indicates that cranberries are well tolerated and risk-free if consumed in modest amounts.
Limit Salt Intake
The kidneys are important for maintaining a proper balance between salt and water in the body. Eating too much salt may increase blood pressure and make the heart work harder. It may also stress the kidneys, which could have difficulty keeping sodium levels balanced, according to MayoClinic.com. The website indicates that an adult should not consume more than 2,300mg of sodium daily. Limit your salt intake by avoiding processed foods that are typically high in salt, such as lunch meats, some canned vegetables and soups, and fast food. Check food labels for sodium content and consider using less salt than indicated in recipes when cooking at home.
