I'd just like to support earlier remarks I made. Sodium is a more complex issue or a more complex nutrient to take control of in the food supply. It has several functions in food, and finding replacements for those functions is not straightforward or simple. Taste is one of them, but it's not the only one. As we all know, taste is paramount in the consumer's world or acceptance of a food product. That's where time is going to be required, not just to change products or to find other solutions, but to adapt the whole population's palate towards a lowered sodium taste profile.
Yes, it may only take three weeks in a controlled study to change the palates of a group of people, but to Dr. L'Abbé's point, we're talking about changing the palate of the whole population, and that's not going to take just three weeks.
