Key result
Reducing salt intake by 9 g/d (from 12 to 3 g/d) would reduce strokes by approximately one third and ischemic heart disease by one quarter.
Why the study?
Does salt reduction lower blood pressure in a dose-dependent manner in hypertensives and normotensives?
Meta-Analysis
Does salt reduction lower blood pressure in a dose-dependent manner in hypertensives and normotensives?
A further reduction of salt intake to 3 g/d demonstrates a consistent dose-response reduction in blood pressure, suggesting greater cardiovascular benefits than current 5-6 g/d recommendations.

Supports targeting 3 g/d salt intake for major stroke and IHD reductions; extends meta-analytic evidence for dose-dependent benefits beyond current 5-6 g/d guidelines.
He et al. (2003) conducted a meta-analysis in Hypertension and normotension. Salt intake reduction vs. Current salt intake (9 to 12 g/d) was evaluated on Fall in blood pressure. Reducing salt intake by 9 g/d (from 12 to 3 g/d) would reduce strokes by approximately one third and ischemic heart disease by one quarter.
