Using Positive Nudge to Promote Healthy Eating at Worksite: A Food Labeling Intervention.

Objective: To assess the effect and transferability of a workplace food labeling intervention.

Methods: Employees' purchase of food items in cafeterias of an international company was monitored in six intervention sites (one in France and five in the United States [US]) where green-labels were displayed in healthy food items. One cafeteria in France represented the control site.

Impact of a front-of-pack nutritional traffic-light label on the nutritional quality and the hedonic value of mid-afternoon snacks chosen by mother-child dyads.

The aim of this study was to assess the impact of a nutritional traffic-light label, the Nutri-Score, on snack choices in mother-child dyads and to assess a potential hedonic cost associated with a change in favour of healthier choices. French mothers and children (n = 95; children's age: 7-11 years) who participated were asked to choose, for themselves and for the other dyad member, a snack composed of one beverage and two food items selected among several products with different nutritional quality. In the first step, the products were presented without any information.
