Reduced salt doesn’t save lives: review
A COCHRANE review finding little evidence that reducing dietary sodium saves lives should be taken with a “pinch of salt”, says an Australian who is spearheading efforts to curb its consumption.
Professor Bruce Neal, chair of the Australian Division of World Action on Salt and Health, (AWASH) said the review was insufficiently powered to assess health impacts and this was acknowledged by the authors.
“This, absolutely, is not evidence that should in any way derail the public health effort that we are making to try and get salt out of food,” Professor Neal told MO.
“It is not a decent piece of science… To be honest, it needs to be treated with a very large pinch of salt.”
The meta-analysis included seven randomised, controlled trials of salt reduction interventions involving 6500 patients, among whom around 600 had died by up to 13 years follow-up.
