Salt: a narrative review and local policy initiatives in Israel.

Abstract

High salt intake is a well-known risk factor for cardiovascular disease (CVD). Some recent prospective studies have challenged the salt-CVD link. We conducted a narrative review based on a systematic search and provided a national policy update. We reviewed 14 observational prospective studies in healthy adults, reporting the association between sodium intake and excretion or reduction and CVD incidence. Validated by cohort studies, recommended sodium consumption levels (< 1.5-2 gram per day) are still relevant for the prevention of CVD in adults. We discussed the findings and policy initiatives implemented in Israel. Such initiatives included voluntary and mandatory food labeling, and culturally tailored educational programs. The Ministry of Health in Israel initiated a salt reduction policy in recent years-aimed for the future of the industry as well as the population.
