This is not a recent problem, as was stated, but the issue has been raised to a much greater extent since 2007, and since the announcement from the health minister that a Sodium Working Group was going to be established. There has been extra impetus since 2007. That doesn't mean that no work was done on this previously. Furthermore, international organizations have highlighted this problem, but since 2007 work has sped up with the announcement of the working group and with the number of activities taking place related to data collection and greater stakeholder involvement.
