Opinion statement
Excess sodium intake has an important, if not predominant, role in the pathogenesis of elevated blood pressure, one of the most important modifiable determinants of cardiovascular disease (CVD). In the United States, almost 80 % of sodium in the diet comes from packaged and restaurant foods. Given the current food environment, educational efforts such as clinician counseling are useful, but a comprehensive public health approach is necessary to achieve meaningful reductions in sodium intake. A successful approach includes several key strategies, which together will both promote positive decisions by individuals and change the context in which they make those decisions. The strategies include 1) public education, 2) individual dietary counseling, 3) food labeling, 4) coordinated and voluntary industry sodium reduction, 5) government and private sector food procurement policies, and 6) FDA regulations, as recommended by the Institute of Medicine, to modify sodium’s generally regarded as safe (GRAS) status. Population-wide reduction in sodium intake has the potential to substantially reduce the public burden of preventable CVD and reduce health care costs.

Institute of Medicine. Strategies to Reduce Sodium Intake in the United States. Washington, D.C.: National Academy Press; 2010. This report recommends key strategies to reduce population sodium intake in the US. The primary recommendation is that the US Food and Drug Administration regulate levels of sodium chloride (salt) in food by altering the GRAS (Generally Recognized as Safe) status of sodium. In addition, the report contains a comprehensive overview of the issues related to sodium reduction, including scientific evidence for sodium reduction, current sodium intake levels in the US, the role of salt and sodium in taste preferences and food science, and the US regulatory environment.

Through rigorous modeling, this study estimates the impact of population salt reduction on cardiovascular disease, mortality, and health care costs. It is projected that reducing population salt intake by 3 g per day will prevent, annually, between 44,000 and 92,000 deaths; 60,000 to 120,000 new coronary heart disease cases; and 32,000 to 66,000 strokes.
