It's actually the other way around. We work very closely to prioritize the ones where it seems like there is more evidence moving in a particular direction. Then we work with our American colleagues to get studies done and come up with the new dietary reference intakes, which we then incorporate into our guidance.
There is a whole bunch of research going on. If we see that there might be a direction that's changing, we then put together bodies of eminent scientists who will look at that and make a recommendation with respect to change in the dietary reference intakes. Then, as they change, we incorporate that into our guidance.
