Replacing regular salt with a salt substitute lowers blood pressure and protects against life-threatening heart conditions, stroke and death from all causes, research suggests.
However, research published in the journal Heart has revealed that swapping regular salt for a substitute, in which a portion of the sodium chloride is replaced with potassium chloride, reduces these health risks.
The team found that salt substitutes reduced blood pressure in all participants, regardless of region, age, sex, weight and blood pressure-related factors.
“These findings are unlikely to reflect the play of chance and support the adoption of salt substitutes in clinical practice and public health policy as a strategy to reduce dietary sodium intake, increase dietary potassium intake, lower blood pressure and prevent major cardiovascular events,” the researchers write of the new study.
But Parker cautioned: “While low salt substitutes have less sodium than regular salt, they still contain potassium which may not be suitable for some people with a heart problem and other existing health conditions
