10 Common Habits That Can Damage Your Kidneys

3. Salt

A healthy diet should include a maximum of 2300 mg of sodium per day (about a teaspoon of salt). If you eat too much salt, your kidneys have to work harder in order to eliminate the excess of sodium, so they might start retaining water which could lead to high blood pressure.

To keep your kidneys healthy, you could add spices and herbs to your foods instead of abusing the salt shaker. You could also reduce the consumption of processed and packaged foods, like canned soups or vegetables, frozen pizza, and salad dressings, as they usually contain lots of salt.
