Noncommunicable diseases (NCDs) are the main contributor to mortality and morbidity globally (1, 2), and interventions to reduce the burden of NCDs are highly cost-effective (3). Elevated sodium intake has been associated with a number of NCDs (including hypertension, cardiovascular disease and stroke), and decreasing sodium intake may reduce blood pressure and the risk of associated NCDs (4, 5). Recent data on sodium intake show that populations around the world are consuming much more sodium than is physiologically necessary (6). In many cases, they are consuming much more than the current World Health Organization (WHO) recommendation on sodium consumption for adults, which is 2 g sodium/day (equivalent to 5 g salt/day) (7). Since the publication of the previous WHO guideline on sodium intake (7), an appreciable amount of scientific evidence concerning sodium intake, hypertension and risk of cardiovascular disease has been published. Member States and international partners therefore requested WHO to review the current guideline on sodium intake for adults, and to also generate a guideline on sodium intake for children.
