Research presented at the European Congress on Obesity in Malaga has revealed a startling connection between the marketing of unhealthy foods and increased calorie consumption among children. According to the study, just five minutes of exposure to junk food advertising can lead children aged seven to 15 to consume an additional 130 calories a day—roughly equivalent to a small chocolate bar. This alarming finding highlights the concerning influence of advertising across various platforms, including social media, television, and podcasts, on children's dietary behaviours.
The lead author, Professor Emma Boyland from the University of Liverpool, noted that “Even short exposure to marketing of foods high in fat, salt, and sugar can drive excess calorie consumption and potentially weight gain, particularly in young people who are more susceptible to advertising and whose eating patterns influence their lifelong health.” The study involved 240 children, and the analysis showed a clear pattern: after viewing advertisements for foods high in saturated fat, sugar, and salt (HFSS), children consumed more snacks and meals than after being exposed to non-food ads. Those with a higher body mass index demonstrated an even greater responsiveness to these advertisements.
The urgency of mitigating such marketing impacts is reinforced by rising childhood obesity rates in the UK, where one in five children are classified as obese by Year 6. Current government initiatives, including a ban on the targeting of junk food advertisements at children, aim to curb this trend. Set to take effect in October, the ban will restrict advertising for less healthy foods on television during prime hours and in online paid promotions. Campaigners argue that these measures are essential for addressing public health concerns exacerbated by easy access to cheap, unhealthy food, particularly among low-income families.
Despite such regulatory efforts, challenges remain. The food industry has resisted numerous proposals to limit marketing for ultra-processed foods, which have been linked to debilitating health outcomes, including obesity, diabetes, and cancer. Lobbying efforts have resulted in a significant regulatory backlash—outpacing even the tobacco and alcohol industries in their resistance. Countries such as Belgium and Israel are now pointing to ultra-processed foods in dietary guidelines, yet the global regulatory landscape remains inconsistent, often targeting junk food marketing only at vulnerable populations.
Similar studies from Canada further underline the need for urgent action. A recent assessment indicated that over half of Canadian children are exposed to unhealthy food marketing across digital platforms, with social media being the predominant medium. Fast food promotions accounted for a substantial portion of this exposure, raising alarms about the pervasive influence of digital marketing on young audiences. The critical role of social media influencers in promoting unhealthy options, particularly among children aged 10 to 12 years, has prompted calls for government interventions to include these newer marketing channels in regulatory measures.
All these findings converge on a singular conclusion: urgent policies are required to limit the exposure of children to unhealthy food marketing across all platforms—be it traditional media or emerging digital spaces. The delicate balance involves ensuring children have access to nutritious options while regulating the environments that encourage unhealthy eating habits, thus shaping healthier generations for the future.
The government’s upcoming advertising ban aligns with a growing consensus that more robust strategies are essential to combat the detrimental health implications of junk food marketing. As we move toward implementing such policies, the implications for public health could be significant, potentially stalling the rising rates of childhood obesity and fostering a healthier, more informed generation.
