We recently did a blog post on dietary salt and health, particularly with regard to a new large prospective study (the PURE Study). This facilitated useful feedback from others, along with input from colleagues in a journal club we ran. Based on these discussions, we now have stronger concerns about remaining reverse causation in the PURE Study (and persisting concerns regarding other aspects). Here we update some of our thinking and conclude that the totality of the available evidence is sufficient for health authorities to continue taking a range of evidence-based actions to reduce the hazard of high salt intakes. Again however we invite critical comment on our assessment and suggestions on where to from here.
