The tendency to have high blood pressure is inherited. If you have relatives who have high blood pressure, it would be a good idea to eat less salt. In the United States this represents about one out of six or seven people. Excess weight adds to the risk and the extra food eaten by overweight people may increase their salt intake. African-Americans, Hispanics, and older people are at higher risk than Native Americans, Asians, or younger people.

The rest of our fresh foods contain some sodium naturally. Processed foods are usually considered high in sodium, however, many new products are lower that they were several years ago.

Some water in the Duluth area has naturally occurring high levels of sodium.
