The World Health Organization has a target of reducing global population salt intake by 30% by 2025. This has made Cochrane’s new systematic review on the efficacy and safety of low sodium salt substitutes (LSSS) timely. The Cochrane systematic review and meta-analysis examines the evidence regarding the use of LSSS on cardiovascular health in adults and children and included blood pressure as a primary outcome.
Rachael McLean, from the Department of Preventive and Social Medicine, University of Otago, New Zealand, discusses the latest Cochrane evidence and how it can support policymakers in their efforts to reduce sodium intake and how applicable the evidence may be in different settings and populations.
Rachael McLean explains:
“In some countries, more than 50% of the salt intake comes from salt used in the home. Cochrane’s review of the evidence on low sodium salt substitutes is valuable for policy makers looking to make substantial impacts for cardiovascular health and in directing researchers where further studies are urgently needed.”
