Group 1 - Sodium is an essential element for the human body, playing a crucial role in maintaining fluid balance and ensuring normal nerve and muscle function. However, excessive sodium intake can be harmful to health [1] - Daily sodium intake primarily comes from three sources: home cooking, dining out/takeout, and processed foods. To avoid excessive salt consumption, it is necessary to address these three areas [1][2] - In home cooking, using salt-limiting tools such as salt shakers and measuring spoons can help control sodium intake. Additionally, substituting regular salt with low-sodium salt, which contains 60%-70% of the sodium found in regular salt, can reduce sodium consumption while still satisfying taste [1] Group 2 - When dining out, restaurant dishes typically have a higher salt content than home-cooked meals. It is advisable to reduce the frequency of eating out and ordering takeout. If necessary, customers can request "lightly salted" options from restaurants and avoid high-sodium dishes [2] - When purchasing pre-packaged foods, consumers should carefully check the sodium content on nutrition labels and prioritize products with lower sodium levels. It is also recommended to limit the purchase of processed meats, salted nuts, and preserved fruits, which are high in hidden salt [2]
