Children wield surprising power over what parents actually purchase
In households across England, the checkout line has become a quiet battleground between parental intention and the persuasive pull of a child's desire — a dynamic that a new study reveals is neither random nor innocent. Research presented at the European Congress on Obesity finds that more than half of parents are regularly pressured by their children to buy unhealthy foods, and nearly three-quarters comply, suggesting that the food industry's marketing strategies are working not on children directly, but through them. The study invites a deeper question: when the environment itself is engineered to generate desire, who bears responsibility for what ends up in the basket?
- Children as young as four are deploying tantrums, shelf-grabbing, and emotional appeals to steer family food purchases toward ice cream, sweets, and crisps — and it is working seven times out of ten.
- The pressure falls hardest on families least able to absorb it: food-insecure parents report being pestered 13% more often, turning the supermarket into a source of financial and emotional distress.
- Product placement at children's eye level and junk food advertising on television and online are directly triggering requests in roughly one in four to one in three households, implicating the designed food environment as a co-author of these family conflicts.
- The UK has introduced checkout bans, promotion restrictions, and a pre-watershed advertising ban — but outdoor billboards, brand social media, and uneven retailer compliance leave significant gaps in the regulatory shield.
- Researchers are now conducting focus groups to map the in-store experience from the child's perspective, seeking evidence that will determine whether current rules are enough or whether a more sweeping overhaul of food marketing is required.
Nearly six in ten parents in England say their children regularly pressure them to buy junk food while shopping — and most of the time, the parents give in. A study of over a thousand parents, part of a project called PUSHED and led by Professor Emma Boyland of the University of Liverpool, found that 58% experience frequent pestering for high-fat, high-salt, or high-sugar products, with 72% often purchasing the requested items despite their own reservations. Shopping with children ranked as the second most common trigger for unplanned food purchases, just behind in-store price promotions.
The survey, conducted across England in September 2025, revealed that children of all ages made demands, though those aged 4 to 11 were far more persistent than teenagers and three times more likely to ask than toddlers. Ice cream and lollies topped the wish list at 45%, followed closely by candy and biscuits. Children almost never pestered for healthy foods. Their tactics ranged from simple verbal requests to tantrums and physically placing items into the trolley — with older children more likely to reference advertisements or in-store displays they had encountered.
The financial and emotional cost was considerable. Ninety-one percent of parents said they spent more than planned because of their children's requests, and nearly a quarter reported feeling guilty or distressed. Families experiencing food insecurity were pestered 13% more frequently, compounding the strain on those with the fewest resources. The study situates these dynamics within a broader public health concern: one in three 11-year-olds in England leaves primary school overweight or obese.
The UK has introduced a series of regulatory measures — banning junk food at checkouts, restricting buy-one-get-one-free promotions, and prohibiting unhealthy food advertising before 9 p.m. on television and online as of January 2026. Yet outdoor advertising and brand social media accounts remain largely unregulated, and it is still unclear whether retailers are consistently complying with existing rules. Researchers are now running focus groups with children and parents to better understand what drives pestering in the store environment, as the question of whether current policy is sufficient — or whether stronger enforcement and broader restrictions are needed — remains open.
Nearly six in ten parents in England say their children regularly badger them to buy junk food while shopping—and most of the time, the parents give in. A new study of over a thousand parents, set to be presented at the European Congress on Obesity this month, found that 58% experience frequent pestering from their kids for products loaded with fat, salt, or sugar, whether in physical stores or online. Even more striking: 72% of those parents report they often end up buying what their children ask for anyway.
The research, part of a larger project called PUSHED, suggests that children wield surprising power over household food purchases. Shopping with kids ranked as the second most common reason parents made unplanned food buys—just behind price promotions and in-store deals. Emma Boyland, a professor of food marketing and child health at the University of Liverpool who led the work, put it plainly: while children aren't the ones paying at checkout, their influence over what parents actually purchase is substantial and measurable.
The study surveyed 1,050 parents across England in September 2025, asking detailed questions about how often their children pestered them, what tactics kids used, and what seemed to trigger the requests. The picture that emerged was remarkably consistent. Children of all ages made demands, though younger kids aged 4 to 11 pestered far more than teenagers, and were three times as likely to make requests as toddlers. The items most frequently requested were predictable: ice cream and lollies topped the list at 45%, followed by candy at 43% and sweets and biscuits at 42%. Notably, children almost never pestered for healthy foods.
How children went about their persuasion varied by age and background. More than half simply asked verbally. One in five deployed emotional tactics—nagging, tantrums. About a third physically picked items off shelves and placed them in the basket or trolley. Older teenagers were less likely to throw tantrums and more likely to point out in-store displays or ads they'd seen. The researchers found that product placement itself was a major culprit: items positioned at children's eye level or near checkouts triggered requests in 29% of cases. Branded characters on packaging and food advertisements on television or online before shopping trips drove requests in roughly one in four households.
The financial and emotional toll on parents was substantial. Nearly all—91%—said they spent more money than they'd planned because of their children's requests. Almost a quarter reported feeling upset, guilty, or distressed by the situation. The burden fell heaviest on families already struggling. Parents experiencing food insecurity reported being pestered 13% more frequently than others, adding stress to households with fewer resources to absorb unexpected spending.
Context matters here. One in three 11-year-olds in England are overweight or obese by the time they leave primary school. While obesity has many causes, researchers point to environments saturated with marketing for unhealthy foods as a primary driver of children's preferences and consumption patterns. The food environment—both what's visible in stores and what appears in advertising—shapes what children want and, by extension, what parents buy.
The UK has taken some steps. Since October 2022, most retailers have banned placing high-fat, high-salt, high-sugar products at checkouts. Promotions like buy-one-get-one-free on junk food were restricted starting in October 2025. A ban on advertising unhealthy foods before 9 p.m. on television and online took effect in January 2026. Yet significant gaps remain. The restrictions don't cover outdoor advertising—billboards, bus shelter posters—or brand social media accounts, even when those brands are primarily known for unhealthy products. It's not yet clear how well retailers are adhering to existing rules or whether the changes have actually shifted what families buy. Dr. Magdalena Muc, a co-author from the Open University, noted that researchers are now running focus groups with children and parents to better understand the in-store experience and what drives pestering behavior. The question now is whether current regulations will prove sufficient, or whether stronger enforcement and broader restrictions on marketing will be necessary to meaningfully change the food environment families navigate.

While children might not be paying the bill at the checkout, their influence over their parents' purchasing decisions is very real.— Emma Boyland, Professor of Food Marketing and Child Health, University of Liverpool
Children are highly susceptible to powerful and sophisticated marketing of unhealthy foods and beverages, and frequent exposure prompts them to pester their parents, putting them at greater risk of developing overweight and obesity.— Dr. Magdalena Muc, Open University
The Hearth Conversation Another angle on the story
Why does it matter that kids pester their parents for junk food? Isn't that just normal childhood behavior?
It matters because it's not random. The pestering is being engineered. Kids see a character on a cereal box, or an ad on YouTube, or a product placed right at their eye level in the checkout line—and then they ask for it. Parents feel the pressure and buy it. That's not just kids being kids; that's a system designed to move products.
But parents can say no, right? They're the adults.
They can, and some do. But 91% of parents in this study spent more than they planned because of their kids' requests. When you're tired, when your child is upset, when you're food insecure and stressed—saying no gets harder. And the system isn't neutral. It's actively working against the parent.
What surprised you most in the findings?
That food-insecure families were pestered more frequently. These are the families with the least money to absorb unexpected spending, and they're the ones getting pressured hardest. And a quarter of parents said the whole thing made them feel guilty or distressed. This isn't just about obesity statistics. It's about real emotional weight on real families.
The UK has banned some things—checkout placement, certain promotions. Is that working?
Nobody knows yet. The rules are new. But there are huge loopholes. Billboards, bus shelters, brand social media—all still fair game for junk food ads. And we don't even know if retailers are following the rules they're supposed to follow. It's a start, but it's incomplete.
So what would actually work?
You'd need to change the entire food environment—not just one shelf or one time slot. Restrict advertising more broadly. Make healthier options more visible and accessible. Make it harder, not easier, for companies to reach children with marketing for products that make them sick. Right now, the system is tilted the other way.
