Is it better for food to have high or low sodium content?

The level of sodium in food is not absolutely good or bad; it depends on an individual's health status and needs. Adequate sodium intake is essential for maintaining physiological functions such as fluid balance, nerve transmission, and muscle contraction. However, excessive sodium consumption increases the risk of health problems such as high blood pressure, heart disease, and stroke. Therefore, for the general population, moderate sodium content in food is ideal—sufficient to meet physiological needs while avoiding excessive intake. For individuals who need to restrict sodium, such as those with hypertension, choosing low-sodium foods is more appropriate. The sodium content in food should be selected according to individual circumstances, and maintaining an appropriate intake level is key.
