Final answer:
A food must contain no more than 140 mg of sodium per serving to be labeled as "low sodium." This helps individuals stay within the recommended daily intake and maintain a healthy diet.
Step-by-step explanation:
For a food to be labeled as "low sodium," it must meet specific nutritional criteria set by regulatory bodies. According to guidelines, foods that are low in sodium contain no more than 140 mg of sodium per serving. Consuming foods with low sodium content is essential for maintaining healthy blood pressure levels and overall health. The recommended daily intake of sodium for an average adult should be less than 2,300 mg, with an ideal limit being closer to 1,500 mg for certain groups at risk for heart disease. It is also important to compare sodium in various foods like soups, bread, and frozen meals, opting for those with lower sodium levels.
