[Editorial] Evidence-based policy for salt reduction is needed
Evidence-based medicine has become the bedrock of treatment guidelines, but why does evidence-based medicine not translate into evidence-based policy? Governments and health organisations around the world are advocating salt intake be reduced, but little robust evidence exists to support a reduction in salt for the general population. Indeed, the few randomised controlled trials (RCTs) available have not strongly supported the benefit of salt reduction in normotensive populations. There is no real disagreement that high salt intake is associated with high blood pressure, and most studies indicate that high blood pressure is associated with more cardiovascular events.
