Sodium and Health Virtual Collection
Sodium is an essential nutrient. However, concern about the adverse consequences of excess dietary intake has led authorities to recommend increasingly restrictive sodium intake. Indeed, current guidelines recommend less than 2300 mg/d for all, and less than 1500 mg/d for roughly 50% of Americans. These levels are far below the mean intakes of 3600 mg/d consumed by 90% of the world’s population.
In 2013, the US Institute of Medicine (IOM) reviewed the evidence linking sodium intake to health outcomes and concluded that concern existed for sodium intakes of less than 1500mg/d, and there was insufficient evidence to determine whether intakes of less than 2300 mg/d were harmful or beneficial.
Since that report, findings from 3 studies, a modeling exercise, and a reanalysis of epidemiological data from an earlier clinical trial have been published. Their results confirm and add to new evidence to the issues raised in the IOM report.
This free collection will be supplemented at regular intervals with the latest research, in order to provide those in the field with an up-to-date, authoritative, and accessible resource on the topic.
