Say No to Salt
Reduce the salt in your diet. It may help lower blood pressure and protect your kidneys. Not salting the food on your plate may not be enough. Most of the salt in Americans' diets comes from processed foods. Avoid convenience foods and use fresh ingredients when you can. Season with herbs and spices instead of salt when you cook.
Adults age 51 and older, and individuals with high blood pressure, diabetes, or chronic kidney disease should reduce their sodium intake to 1,500 mg a day -- that's less than half a teaspoon of salt.
