Social media platforms and algorithms aggressively target children with ads for ultra-processed foods, often disguised as organic content (e.g., influencer posts, games and quizzes). Over 70% of children encounter such ads within minutes of logging in.
Outdated regulations and voluntary corporate measures fail to curb harmful marketing. WHO warns that self-regulation has not worked, urging mandatory restrictions on unhealthy food ads targeting youth.
Children worldwide—from the U.S. to Australia—face relentless exposure via smartphones and apps. Teens see up to 189 junk food ads weekly, with tactics varying by gender (e.g., athleticism-themed ads for boys, diet quizzes for girls).
Researchers demand stricter laws to limit algorithmic targeting, influencer promotions and exploitative loopholes. Public awareness campaigns and media literacy education are also critical to help children recognize manipulative ads.
Childhood obesity linked to digital marketing increases risks for chronic diseases like diabetes and heart disease. Experts compare unchecked food marketing to tobacco—urging governments to prioritize public health over corporate profits.

A new global study warns that digital marketing strategies on social media are exacerbating childhood obesity by flooding young people with ads for ultra-processed foods, often in ways they cannot recognize. Researchers from the University of Oxford, along with collaborators in North America and Oceania, found that children and teens are bombarded with junk food promotions through personalized algorithms, influencer campaigns and interactive content, actively shaping their eating habits. Published in the BMJ Global Health, the analysis of 80 international reports involving nearly 20,000 children and adolescents concludes that outdated policies and voluntary corporate efforts are failing to curb this crisis, calling for urgent regulatory reforms and public awareness campaigns.

A hidden influence: How algorithms shape unhealthy diets

The study highlights how social media platforms like TikTok, Instagram and YouTube exploit behavioral tracking and algorithmic learning to deliver ads targeting youth. These ads often blend seamlessly into games, quizzes and influencer posts, making it difficult for children to distinguish marketing from organic content. For instance, videos showcasing sugary snacks during live streams or “unboxing” videos of fast-food meals normalize junk food consumption. A Canadian study cited in the review found that 72% of children ages 7–16 encountered food marketing within 10 minutes of logging into their preferred social apps. Dr. Cervantee Wild, senior author of the study, underscores the subtlety of these tactics: “Children deserve to grow up in an environment that supports their health, not one that constantly encourages them to eat junk food.” The research further reveals that even when parental controls are applied, exposure persists. A 2023 review by Australia’s Institute of Health and Welfare found that over 90% of food ads seen on children’s websites promoted items high in sugar, salt, or fat—categories like cakes, cookies and ice cream.

Global reach, disproportionate impact

The crisis is not confined to any single region. In the U.S., 95% of adolescents own smartphones, with 35% reporting near-constant use of top platforms like TikTok and Instagram—creating a “hyperconnected generation” bombarded with unhealthy choices. Similarly, in the U.K., nine in 10 children own a mobile phone by age 11, while in Australia, nearly a quarter of 5- to 7-year-olds have their own devices. New Zealand’s food brands leveraged pandemic themes to stay relevant during lockdowns, with 14 of the top 20 unhealthy brands using coronavirus-related messaging. The study also notes stark disparities by gender and age. Boys are more likely to see ads emphasizing achievement or athleticism, while girls face interactive content like polls or diet-related quizzes. Older teens (ages 13-18), meanwhile, face higher daily exposure due to prolonged platform use—up to 189 ads weekly on apps like TikTok, according to Canadian data.

The digital marketing arms race outpaces regulation

Public health advocates argue that voluntary corporate policies, which dominate current approaches, are inadequate to counter aggressive digital tactics. The World Health Organization (WHO) first issued warnings about food marketing’s health risks over a decade ago but reiterated in 2023 that self-regulation has failed. Its latest guidelines urge mandatory restrictions on ads for high-sugar or high-salt foods targeting children—which have been largely ignored. The study emphasizes that outdated regulatory frameworks designed for TV or print advertising can’t address the evolving nature of digital content. Platforms often exploit loopholes, such as defining teens as “youth” rather than “children” to bypass restrictions, or embedding ads in “user-generated” formats. In the U.S., legal precedents like Citizens United have further hindered progress, as courts classify corporate speech as free speech protected under the First Amendment.

A call for global action and parental vigilance

The researchers recommend a multi-faceted approach, including stricter cross-border policies to curtail algorithm-driven ad targeting, mandatory curbs on influencers promoting unhealthy foods, and increased transparency around data collection practices. They also stress the need for education programs to teach children how to identify and resist marketing influences. Parents are urged to advocate for systemic reforms while reinforcing media literacy at home. “Self-regulation has proven ineffective,” Dr. Wild explains. “We must shift accountability to legislative bodies to safeguard children’s health.” Meanwhile, tech companies and policymakers are under pressure to revisit ethical standards in child-targeted advertising—especially as platforms challenge regulatory efforts, such as Florida’s 2023 law banning social media accounts for under-16 users.

Protecting tomorrow’s health starts today

The stakes are high: childhood obesity increases risks for chronic conditions like type 2 diabetes, heart disease and diminished immune function, as highlighted in parallel discussions moderated by health experts such as Jefferey Jaxen and Del Bigtree. By acknowledging social media’s role as a “commercial determinant of health”—akin to tobacco or alcohol industries—governments can craft policies that reorient marketing practices toward promoting nutrient-rich foods and healthy lifestyles. The path forward requires closing gaps in regulation and fostering collaboration among nations, tech firms and communities. Without urgent intervention, the study warns, social media will remain a driving force behind a rise in avoidable health crises, leaving future generations to contend with the consequences of today’s unchecked practices.

A global threat demands global solutions

As young consumers grow increasingly connected, the digital environment becomes both a marketplace and a health battleground. The BMJ study illuminates the urgent need for policies that prioritize public health over corporate interests. It is imperative for governments and tech leaders to act swiftly—ensuring that a tech revolution designed for connection does not further deepen the obesity epidemic that now threatens the next generation.
