A low-sodium food additive that tastes like salt and is used as a dietary alternative to salt. A salt substitute contains less sodium that some people want to avoid.
Excess sodium in the diet is linked to many health concerns. Doctors often recommend a low / no sodium intake to their patients. Reducing salt intake is one of several ways that people may lower their blood pressure. The relationship between salt intake and blood pressure is direct and progressive without an apparent threshold. Reducing blood pressure, ideally to the normal range, reduces the risk of heart failure stroke, heart disease and kidney disease.
