I can start, and Phil can follow.
In terms of the impact of reducing sodium from a health point of view, it's interesting if you look globally at some of the factors that are producing complications. One, for example, is malnutrition worldwide; that's not a problem in Canada. But the other aspect is high blood pressure. One in four of us in this room has high blood pressure, and as we get older the incidence gets higher. If you can reduce sodium, about one-third of us who have high blood pressure can have normal blood pressure. You may not even need to be treated with medication.
People have done some comparisons. For example, comparing to trans fats, comparing to other types of policy changes, if the sodium reduction impact is fully implemented, it's about three to four times higher than many of the other strategies. So I think this is part of the reason that sodium reduction is a very worthwhile venture to be investing time and effort in.
