Hardly anyone uses this surprisingly simple fix for high blood pressure

Salt substitutes, which replace sodium with potassium and can help manage blood pressure, are underutilized by Americans with hypertension. Research presented at the American Heart Association's Hypertension Scientific Sessions shows that less than 6% of U.S. adults use these inexpensive alternatives. Usage has declined from 5.4% in 2013-2014 to 2.5% by early 2020. Even among those with poorly controlled hypertension, most continue to use regular salt, missing an opportunity for better blood pressure management.
