On July 8, 2026, a new study from New York University reveals that social media influencers who share racial and ethnic identities with their audiences have a significant and potentially unhealthy impact on youth food choices. The research highlights how this "identity congruence" can lead to increased engagement with unhealthy food marketing among adolescents.
Understanding Identity Congruence in Influencer Marketing
Food marketers have increasingly turned to influencers who mirror the racial and ethnic identities of their target demographics, viewing this strategy as more persuasive. This trend has escalated on social media platforms, where influencers reach millions, particularly impressionable youth. According to the study, minority adolescents pay more attention to influencers who resemble them, which raises concerns about the influence of unhealthy food choices.
Emily Balcetis, an associate professor at NYU’s Department of Psychology and the study's lead author, stated, "When influencers share those identities, they grab attention and signal what people like their followers do, value, and eat." This suggests that identity-based marketing could significantly shape eating behaviors among adolescents.
How Influencer Posts Affect Food Preferences
The study included two experiments to assess how racial congruity in influencer marketing affects food preferences among different racial groups. In the first experiment, over 500 teenagers aged 13 to 19 were shown images of influencers endorsing either unhealthy food or non-food products. The findings revealed that Black adolescents found posts featuring racially congruent influencers more engaging than those with incongruent influencers.
