Elevated blood pressure is a highly prevalent condition that is etiologically related to coronary heart disease and stroke, two of the leading causes of morbidity and mortality throughout the world. Excess salt (sodium chloride) intake is a major determinant of elevated blood pressure. In this paper we discuss the scientific rationale for population-wide salt reduction, the types and strength of available evidence, policy-making on dietary salt in the United States and other countries, and the role and impact of key stakeholders. We highlight a number of lessons learned, many of which are germane to policy development in other domains.
