Summary
This comprehensive narrative review by He and MacGregor, published in the Journal of Human Hypertension in 2009, synthesises the epidemiological, clinical, and mechanistic evidence linking high dietary salt intake to elevated blood pressure and increased risk of cardiovascular disease and stroke. The authors, who are prominent advocates for salt reduction policy, draw on a broad body of research to argue that population-wide reductions in salt intake would yield substantial public health benefits. The review is widely cited in discussions of dietary guidelines and public health nutrition policy.
UK applicability
Highly applicable to the UK context: He and MacGregor are based at Queen Mary University of London and have been influential in shaping UK salt reduction policy, including initiatives led by the Food Standards Agency and later Public Health England. The findings directly inform UK dietary guidelines recommending no more than 6g of salt per day for adults.
Key measures
Blood pressure (mmHg); cardiovascular disease risk; stroke incidence; dietary sodium intake (g/day); population-level salt consumption estimates
Outcomes reported
The review examined the relationship between dietary salt (sodium chloride) intake and blood pressure, cardiovascular disease, stroke, and other adverse health outcomes across populations. It also likely assessed the evidence base for salt reduction strategies and their potential public health benefits.
