Proposed Nomenclature for Salt Intake and for Reductions in Dietary Salt

There is considerable confusion about what ranges of dietary salt(a) could be considered low, normal, or high and also what ranges of reduction in dietary salt are small or large. The World Hypertension League with other organizations involved in dietary salt reduction have proposed a standardized nomenclature based on normal ancestral levels of salt intake and also on ranges of reduction in salt intake in clinical and population interventions. Low daily salt (sodium) intake where harm due to deficiency would be expected to occur is recommended to remain undefined because of inadequate research but likely <0.25g (100mg), normal (physiological) intake <2.5g (1000mg), recommended intake <5.0g (2000mg), high 5.0g (2000mg), very high >10 to 15g (4000-6000mg), and extremely high >15g (6000mg). Reductions in daily salt (sodium) intake are recommended to be called small if <2.5g (1000mg), moderate if 2.5 to 5.0g (1000-2000mg) and large if >5.0g (2000mg). Use of this nomenclature is likely to result in less confusion about salt intake and interventions to reduce dietary sodium. (C) 2014 Wiley Periodicals, Inc.
