Using a substitute could be a cost-effective option to cut back on the salt

Embargoed until: Publicly released:

Replacing regular salt with a salt substitute could be a potential cost-saving strategy, according to Aussie and international researchers. The team conducted a trial of 1,612 adults in 48 eldercare facilities across China, splitting the residents into one of four groups: two with salt reduction strategies; one with salt reduction and salt substitution strategies; two with either strategy; and one with neither strategy.  The team found the salt substitution strategies showed considerable potential to be cost-saving, while the salt restriction strategies did not show any difference. In the same trial, a second paper involving the same authors (to be published in a different journal with a slightly different embargo time) found the salt substitution also improved blood pressure. Taken together, these findings show salt substitution could not only be good for health, but also cost-effective.
