World Kidney Day, March 10: Your body’s chief filters need attention

The kidneys act as the body's main filtering mechanism, cleansing blood of bad nutrients, keeping good ones, and removing excess water.

The kidneys also help to control blood pressure, produce red blood cells and keep your bones healthy.

An estimated 26 million American adults have chronic kidney disease (CKD) and millions more are at risk of getting it.

How to protect your kidneys

There is no magic food or remedy that protects kidneys. According to the National Institutes of Health, a healthy body equals healthy kidneys.

That means most of the recommendations for kidney health are things you have heard before:

Exercise

Maintain a healthy weight

Don't Smoke

Don't take excessive amounts of over-the-counter pain medicine such as ibuprofen or naproxen sodium.

Keep your blood pressure at a healthy level.

Control diabetes and keep sugar levels stable.

Reduce salt intake.

Eat a balanced diet.

Drink more water — especially if you take ibuprofen or naproxen sodium.

Most people don't know their kidneys are in danger or failing until it is too late. When symptoms finally occur — itching, fatigue, weakness, nausea and vomiting– it might be an advanced case. Ask your doctor if you should be tested for kidney disease.
