Final answer:
An incorrect nutrient descriptor for sodium would be one that suggests an unhealthy amount per serving as low in sodium. Proper guidance is provided by the nutrition facts label, which should reflect less than 140 mg of sodium per serving or less than 5% daily value for a food to be considered low in sodium.
Step-by-step explanation:
The nutrient descriptor for sodium on a food label that is incorrect would be any statement that does not align with the established guidelines for sodium intake. Specifically, foods that are considered low in sodium contain less than 140 mg per serving, or 5% daily value. It's recommended that the total sodium intake should be less than 2300 mg per day. Given that the average person only needs about 500 mg of sodium every day and that most people consume much more, often up to 10 times as much, any label suggesting a higher than recommended per serving sodium content that would be considered healthy or low in sodium would be incorrect.
To avoid excess sodium, it is advised to compare the sodium content listed on the nutrition facts label of items like soup, bread, and frozen meals, and to choose options with lower numbers. Additionally, one should stop adding salt at the table and start checking the sodium content on food labels more diligently. With processed and packaged foods being major sources of sodium, reading labels can help manage and reduce sodium intake.
