The mean calories of all food products were significantly fewer in TLL + brochure than in the other groups (without label, TLL, PACE, PACE + brochure). For the food groups, the calories of cakes and biscuits were significantly fewer in the TLL + brochure compared to the other groups. No significant relationship was found between the groups for other food groups. The reported values are means (standard deviations). P value was obtained using the ANOVA method. aPACE: physical activity calorie equivalent; TLL: traffic light label.
