I guess the first thing to say about those population studies is that those kinds of studies don't prove cause and effect. They are associative studies. So you instituted a lower salt diet in a certain country and you see a reduction in cardiovascular disease. Many other things happen during that same timeframe, so we don't know a priori, without studying it, that it's a cause and effect relationship.
It's hard to take that data and extrapolate it to the specific person you're asking about. That's why I think that if there is going to be a change in Canada, we need much more evidence to show that on an individual basis, if you alter the salt content in the foods you eat, it does have an impact on blood pressure, sodium content, and cardiovascular disease. We don't have that information from the associative studies.
