Two papers published in 2021 have shown that salt substitution can help reduce blood pressure [1] and improve all-cause mortality [2]. Both studies were performed in rural populations where exposure to salt in processed and ultra-processed foods (UPFs) is low. The population was randomized in both trials. One group received regular salt for daily use while the other had partial substitution with 25-30% of potassium chloride.https://ift.tt/COgkDTx
