A recent study has shed light on the growing influence children have over their parents’ food purchases, particularly when it comes to unhealthy snacks. Conducted by researchers at the University of Liverpool and presented at the European Congress on Obesity in Istanbul, the findings indicate that many parents frequently give in to their children’s requests for junk food, raising concerns about the implications for childhood obesity.
The Pester Power Phenomenon
The study surveyed over 1,000 parents across England, revealing that 58% admitted to their children frequently pestering them for products that are high in fat, salt, or sugar. As a result, a significant 72% of parents reported that they often end up buying these requested items. This trend is particularly alarming given the current climate surrounding childhood health and nutrition.
Lead researcher Emma Boyland, a professor specialising in food marketing and child health, emphasised the pervasive influence children exert on their parents during shopping trips. “While children might not be paying the bill at the checkout, their influence over their parents’ purchasing decisions is very real,” she noted. Boyland further expressed the urgent need for a transformation in both online and in-store shopping environments to promote healthier choices.
The Impact of Marketing and Promotions
Interestingly, the study highlighted that parents are also influenced by marketing tactics, with 59% admitting to being swayed by price promotions and in-store offers. More than half of the parents surveyed revealed that shopping with their children often led to unplanned purchases, indicating that the grocery shopping experience itself can contribute to unhealthy eating habits within families.

The most popular items requested by children included ice creams and lollies (45%), sweets and chocolates (43%), and biscuits (42%). The overwhelming presence of child-friendly branding and advertisements also plays a significant role in these requests, with one-quarter of parents noting that exposure to such marketing tactics prompted their children to ask for unhealthy snacks.
A Struggle for Parents
The emotional toll of this situation cannot be underestimated. Alarmingly, nearly one in four parents reported feeling upset, guilty, or distressed when their children made these demands. Co-author Dr Magdalena Muc from the Open University discussed the broader implications of these findings, particularly for families facing food insecurity. “Children are highly susceptible to powerful and sophisticated marketing of unhealthy foods and beverages,” she stated, warning that this tendency exacerbates the risks of childhood obesity.
The study also revealed that younger children, particularly those aged four to 11, tend to be more demanding than their older siblings. This age group is more likely to actively request specific items, whether verbally or by placing them in the shopping cart. The findings suggest that as children grow older, their awareness of marketing strategies increases, further intensifying their requests for unhealthy foods.
Why it Matters
This study highlights a critical intersection of child health, parental stress, and the pervasive influence of marketing in today’s food landscape. As children increasingly dictate their family’s food choices, it becomes essential for parents, policymakers, and health advocates to collaborate on strategies that promote healthier eating habits. Addressing the marketing tactics targeting young consumers is crucial, as is creating a supportive shopping environment that empowers families to make nutritious choices. The future health of our children may well depend on these efforts to reshape both consumer behaviour and the food industry.
