Labelling might subsequently have a helpful position, ideally alongside a broader set of approaches that place extra onus on business relatively than people, reminiscent of taxes, advertising restrictions and reformulation.
“However, we should not expect miracles, and any implementation of calorie labelling must balance the many potential positive and negative impacts of such policies.”
