Healthy adults should limit sodium intake levels to less than 2,300 milligrams per day, according to the Dietary Guidelines for Americans. African-Americans, people suffering from high blood pressure, kidney disease or diabetes, and adults over the age of 51 should limit sodium intake to 1,500 milligrams per day.
Most Americans consume around 3,400 milligrams of sodium each day and they get the majority of their salt from processed foods. Although sodium is essential to remaining healthy, too much can result in health issues. The kidneys have to work hard to remove excess sodium from the body and this in turn can lead to conditions such as chronic kidney disease, congestive heart failure and cirrhosis of the liver.
