A low-sodium diet is a dietary plan that limits the intake of sodium, a mineral commonly found in table salt and many processed foods. This type of diet is often recommended for individuals with high blood pressure, heart disease, or kidney problems, as excessive sodium can lead to fluid retention and increased blood pressure. To follow a low-sodium diet, individuals should focus on fresh fruits, vegetables, whole grains, and lean proteins while avoiding processed foods, canned goods, and salty snacks. Reading food labels is essential, as many products contain hidden sodium. Cooking at home with herbs and spices instead of salt can also help reduce sodium intake.
