Kidney Function and Health

Think of your kidneys as the unsung heroes of the body, the organs willing to do the dirty work to keep you healthy. Each one is only the size of a fist—similar to the heart. The primary responsibility of the kidneys is to produce urine by filtering waste and excess fluid from the blood.

Beyond that, however, the kidneys are critical in maintaining the balance of hormones and other chemicals your body needs to function. The organs control your levels of acid, potassium and salt in addition to manufacturing hormones linked to keeping blood pressure and calcium in check. The kidneys even regulate red blood cell production.

Caring for your kidneys is luckily as easy as caring for yourself. Many of the healthy lifestyle choices you make every day are steps toward healthy kidneys. Those include managing your blood pressure and cholesterol in addition to regular exercise.

What you put into your body is also essential for kidney health. Incorporate plenty of whole grains, low-fat dairy and fresh fruits and vegetables into your diet and avoid excessive amounts of alcohol and sodium.

Drinking water helps your kidneys function at their optimum level. Water dilutes waste and helps clear out kidney stones before they get large enough to cause problems. But how much water is enough?

The Mayo Clinic recommends women consume 92 ounces of water per day. Men should drink 124 ounces. That number may be different while you are in a warm climate, are very active or have a disease that makes it difficult for your kidneys to process fluids.

To stay hydrated, try:

• Drinking water instead of sugary beverages such as juice
• Eating water-rich foods, such as soup, melon, cucumber and celery
• Avoiding drinks that can dehydrate you, such as alcohol
