It would be interesting to use what is currently being done with other groups. I come back to the example of the diabetics because, for them, it is really important to have a basis for comparison. They already have their concept of a standard serving. The Canadian Food Guide already provides the size of a standard serving, a standard serving of cereal, for example. It should be enough to bring everyone around the table and to agree that we are going to use the same standard servings. This is not a scientific issue, far from it. Everyone just needs to have the will to agree.
