The average daily intake of sodium in the US is about 3400 mg. Dietary guidelines recommend reducing it to <2300 mg/day in general, and to 1500 mg for African Americans, persons with hypertension, diabetes or chronic renal disease, and for all those >50 years old.1 Salt reduction lowers blood pressure, and lowering blood pressure reduces the risk of myocardial infarction, stroke and death.2
