I will try to answer that.
One of the points is that when you do make a change in the salt content of foods, it's very important to measure the outcomes—the anticipated as well as the unanticipated outcomes.
The Institute of Medicine report—I see the book there, if you want to look at it—in 2001 actually identified a bunch of gaps in knowledge that really do need to be identified, whether it's a voluntary or mandated change in salt. For example, if you lower salt content in diet, what's the impact on children and their later life—not just the immediate impact, but many years later—and on pregnant women and other vulnerable populations? If there is a change in salt in the diet, our job is to monitor what happens to make sure there is documented benefit, but also to monitor to make sure there is no adverse outcome. We have been working since the beginning of this year to put together the workshop and evaluate if there is a policy change.
