Sodium is an essential nutrient required by the body for maintaining proper blood pressure and for providing channels of nerve signaling.
Deficiency of sodium is rare but can occur in people after excessive vomiting or diarrhea, in athletes who consume excessive amounts of water, or in people who regularly fast on juice and water.
Over-consumption of sodium is far more common and can lead to high blood pressure which in turn leads to an increased risk of heart attack and stroke.
The current daily value (%DV) for sodium is 2400mg, however, the American Heart Association recommends that people with high blood pressure eat less than 1500mg per day, or less than 3/4 of a tablespoon of salt.
Since sodium is required by all life to exist, it is naturally found in all foods and does not need to be added. Foods high in sodium include table salt, sauces, salad dressings, cured meats, bacon, pickles, bullion, instant soup, roasted salted nuts, snacks, fast foods, and canned foods.
Below is a list of high sodium foods, for more, see the extended lists of high sodium foods by nutrient density, list of high sodium foods to boost sodium levels, and the list of high sodium foods to avoid.
