Are there any artificial salt substitutes?

Asked by: Edward Seymour, Hove

Table salt tends to be sodium chloride (NaCl) but salt substitutes contain potassium chloride (KCl), which has a similar taste. These are billed as lowering the risk of high blood pressure and heart disease associated with high sodium consumption.

But potassium chloride is not without its downsides. It can interact with some prescription drugs and can be dangerous if you have kidney problems.
