Table 1 Details of salt substitution strategies including estimated uptake, cost, resources and coverage
Parameter | Voluntary | Subsidised | Regulatory |
|---|---|---|---|
Description | Companies that make target products* voluntarily introduce new products low sodium products with potassium chloride. | Government subsidisation of potassium chloride to equal cost of salt – allowing manufacturers to use potassium chloride in target products* as a salt substitute. | Legislation requiring all target products* to have a portion of their sodium content replaced by potassium chloride. |
Industry uptake | Assumed to be low | Assumed to be moderate | Assumed to be high |
Cost | Extra cost of low sodium products is passed onto consumers | Borne by Government (for subsidy). Manufacturers are assumed to produce and sell low salt products at a similar price to regular products and therefore no extra cost is passed onto consumers | Borne by Government (for legislation) and manufacturers (for production). Low salt products are assumed to be sold at a similar price |
Proportion of target products* reformulated with potassium chloride | 30% | 50% | 100% |
Proportion of people choosing reformulated target products* | 5% | 44% | 100% |
