Low-sodium refers to foods or diets that contain reduced levels of sodium, a mineral commonly found in table salt. Sodium is essential for bodily functions, but excessive intake can lead to health issues like high blood pressure and heart disease. A low-sodium diet typically limits sodium intake to 2,300 milligrams or less per day, as recommended by health organizations. Many processed foods, such as canned soups and snacks, often contain high levels of sodium for flavor and preservation. Choosing fresh fruits, vegetables, and whole grains can help maintain a low-sodium diet. Reading labels and opting for products labeled as low-sodium or no salt added can also assist in managing sodium intake.
