A primary care patient has borderline dietary calcium (600 mg/day) and very high sodium intake. Which counseling priority most directly addresses immediate risks and long-term bone health while applying the major/trace distinction?

Tell the patient to eliminate all dairy immediately and rely solely on multivitamins to maintain bone health because supplements are always preferable to dietary modification for major minerals.

Focus only on adding trace mineral supplements such as iodine and selenium because addressing trace minerals will automatically correct calcium and sodium imbalances and is thus the most efficient approach.

Advise reducing sodium intake to lower cardiovascular risk and reduce urinary calcium loss, and simultaneously counsel on increasing calcium-rich foods to approach recommended intakes for bone health, because both major minerals interact and are high-priority targets.

Recommend simply increasing water intake to dilute sodium without altering diet composition or calcium intake because dilution alone will fully mitigate both blood pressure and bone density risks.
