The article framed the corporations as manipulative marketers trying to hook consumers on addictive junk food for financial gain.

A values-alignment intervention protects adolescents from the effects of food marketing.
Nature Human Behaviour, 2019;
Adolescents are exposed to extensive marketing for junk food, which drives overconsumption by creating positive emotional associations with junk food1,2,3,4,5,6. Here we counter this influence with an intervention that frames manipulative food marketing as incompatible with important adolescent values, including social justice and autonomy from adult control. In a preregistered, longitudinal, randomized, controlled field experiment, we show that this framing intervention reduces boys’ and girls’ implicit positive associations with junk food marketing and substantially improves boys’ daily dietary choices in the school cafeteria. Both of these effects were sustained for at least three months. These findings suggest that reframing unhealthy dietary choices as incompatible with important values could be a low-cost, scalable solution to producing lasting, internalized change in adolescents’ dietary attitudes and choices.
