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 talk with their doctor about how much to reduce their sodium intake. In general, people with diabetes should decrease to less than 2,300 mgs per day, however your doctor may recommend lower amounts.
