Sodium content refers to the amount of sodium present in food or beverages, typically measured in milligrams. Sodium is an essential mineral that helps regulate fluid balance, nerve function, and muscle contractions. However, excessive sodium intake can lead to health issues, such as high blood pressure and heart disease. Many processed foods, such as canned soups, snacks, and deli meats, often have high sodium content due to added salt for flavor and preservation. The American Heart Association recommends limiting sodium intake to less than 2,300 milligrams per day for most adults to maintain overall health.
