The replacement of regular salt with a salt substitute can reduce incidences of hypertension, or high blood pressure, in older adults without increasing their risk of low blood pressure episodes, according to a study published in the Journal of the American College of Cardiology (JACC). Researchers from Peking University Clinical Research Institute in Beijing, China found that people who used a salt substitute had a 40% lower incidence and likelihood of experiencing hypertension compared to those who used regular salt.
