Brief: Graudal et al.’s meta-analysis solidifies the evidence from previous studies and extends the IOM report by identifying a specific range of sodium intake (2,645–4,945 mg/day) associated with the most favorable health outcomes—within which variation in sodium intake is not associated with variation in mortality. Moreover, this optimal range of intake, based upon currently available evidence, is corresponding with the dietary intake of most of the world’s populations and is in accordance with the IOM rules for definition of an adequate sodium intake and an upper tolerable sodium level.
