Should physical activity calorie equivalent (PACE) labelling be introduced on food labels and menus to reduce excessive calorie consumption? Issues and opportunities
PACE food labelling seeks to provide kilocalorie information with an interpretation of what the kilocalorie content of the food item or meal means for energy expenditure. For example, “the kilocalories in this pizza require 110 minutes of walking to expend”. Displaying calorie content in an easily understandable format is important given evidence indicating that the public consistently underestimate the energy content of food when labelling is not provided. Evidence from systematic reviews and trials testing the effects of PACE labelling point to the possible benefits of inclusion on food labels and menus. However, several criticisms of this labelling system have been raised. This commentary explores both the issues and opportunities related to PACE labelling, arguing that the benefits of implementation outweigh potential unintended consequences.
