The adequate intake (AI) level of sodium is set at 1,500 mg per day for adults. This level is formulated based on the amount needed to maintain optimal physiological functions while considering the relationship between sodium intake and health conditions, particularly hypertension. Sodium is an essential nutrient that helps in various bodily functions, including fluid balance, nerve transmission, and muscle function.

The recommendation for an AI level recognizes that individual needs can vary, but this value helps to establish a baseline that aims to prevent deficiencies and support overall health. This is important in dietary guidelines to promote healthy eating patterns.

In contrast, some amounts provided in the other choices fall short of or exceed the AI level based on public health recommendations. The establishment of the 1,500 mg upper limit aligns with guidelines from health organizations, ensuring that it addresses typical dietary habits while avoiding negative health outcomes associated with both low and excessively high sodium intakes.
