Improving populations’ eating behaviors is a priority for public-health authorities, because of the related human and economic costs. Despite the effort spent on nutritional education, the results are disappointing. The present research investigates another approach. It experimentally tests the influence of meal sharing on the intention to take or not nutritional risks. Delineating between routine and festive meal context, it shows that sharing daily meals with the family tends to favor a healthier behavior, while eating with friends in a festive setting encourages a less healthy behavior. This research helps to explain the apparent contradictions in the literature on how the presence of others influences food intake. It also suggests new routes to foster a healthier food behavior and promotes a more holistic approach to food, in accordance with the “food well-being paradigm” (Block et al. 2011; Bublitz et al. 2013).
