Exploring effectiveness of salt substitutes in elderly care facilities

Experiments at 48 elderly care facilities in China find that salt substitutes lowered diastolic blood pressure and resulted in fewer cardiovascular events, according to a paper titled “Salt substitution and salt-supply restriction for lowering blood pressure in elderly care facilities: a cluster-randomized trial,” published in Nature Medicine. Rachael M. McLean has published a News & Views piece in the same journal discussing the findings.
