The findings of a recent study suggest that dietary salt substitutes lower the risk of heart attack, stroke and death from all causes and cardiovascular disease, finds a pooled data analysis of the available evidence, ANI reported.
The findings were published online in the journal Heart.
Cardiovascular disease is the leading cause of death worldwide, and high blood pressure is a major risk for early death. A diet high in sodium and low in potassium is known to drive up blood pressure.
Salt substitutes, in which a proportion of sodium chloride (NaCl) is replaced with potassium chloride (KCl), are known to help lower blood pressure.
A recently published large study from China (Salt Substitute and Stroke Study; SSaSS) found that salt substitutes cut the risk of heart attacks, stroke, and early death, but it was unclear whether these benefits would apply to other parts of the world.
Reductions in blood pressure seemed to be consistent, irrespective of geography, age, sex, history of high blood pressure, weight (BMI), baseline blood pressure, and baseline levels of urinary sodium and potassium.
