  1. *The evaluation of critical nutrients to determine if a product would bear a label varied across the phases of the norm. During the first and second phase of the norm, the evaluation was as follows: if added sugars was added, sugars and calories were evaluated. If fats were added, saturated fats, trans-fats and calories were evaluated; finally, if sodium was added, only sodium was evaluated. In the second and third phases, the thresholds were the same. For the third phase, all critical nutrients must be evaluated if the product contained at least one of them
