Children’s exposure to junk food advertising: can the UK hold firm in the face of industry resistance?

Posted by Chris Baker, primary school teacher and distance learning tutor at the London School of Hygiene and Tropical Medicine

Growing up in a sweet shop was, as you can imagine, an absolute dream. Who wouldn’t want an entire store of confectionery under their own roof? It was the 1990s and I didn’t realise how lucky I was - living above a newsagent run by my parents. I’d get home from school, give a cursory wave to my mum behind the counter and immediately grab a chocolate bar, or an ice cream. It was the best.

Clearly, it wasn’t a recipe for good health. I was continuously surrounded by the bold and colourful logos, the marketing strategies and the special offers - all designed to hook me into habitual consumption. I paid little attention to the nutritional contents of the things I was snaffling (this was long before front-of-package labelling came along). My physical health (particularly my teeth) paid the price.

Cut to 2020 and I find myself thinking back to that era - before the internet, before screen-time, before social media. I am now a primary school teacher (with experience in public health) committed to promoting children’s health and well-being. I see that the relationship between children and junk food today has not changed all that much. There are still products high in fat, sugar and/or salt that kids crave. And what’s helping them to connect with these products? Digital marketing.

I teach ten and eleven-year-olds in an international school, so the demographic group I am most familiar with is not representative of the UK. However, I believe there are important similarities. Many children of this age now have smartphones and use apps intended for older audiences. Through these apps, they are exposed to new and sophisticated marketing strategies, unheard of by older generations.

Fortunately, there are plans to address this. Last year the UK government proposed a total ban of online marketing for foods high in fat, salt and sugar. Not a restriction, or a tightening of rules: a total ban. The preamble to this consultation suggests that completely reducing exposure to ‘endless prompts’ to eat offers the best way forward. The government’s response to the consultation, with an accompanying plan of action, is due to be published this Spring.

The scope and scale of this proposal are noteworthy. To date, no countries have successfully implemented a complete ban (there are strong restrictions in Chile and French-speaking Canada). Implementation of the government’s proposal would place the UK firmly at the front of the pack, delivering strong policy action with the potential for significant public health benefit.

Unsurprisingly, industries affected by such a ban have been critical of the proposals. In an open letter, a consortium of food companies and advertising agencies called for a rethink. Their arguments are predictable and are representative of a cross-industry playbook, seen repeatedly in recent years across several other industries interested in unhealthy commodities. They claim the proposal is disproportionate. They claim the evidence is lacking in detail. They distance themselves from the issue and play down their role. They demand a meeting with the government to discuss ‘alternative’ (but unspecified) approaches.

A total ban would be an entirely appropriate response in the face of an industry that has altered considerably in recent years. An earlier attempt to merely limit adverts for unhealthy foods in and around children’s tv programming (as well as other non-broadcast media) was found to expose children to no less advertising. Artificial separation of children’s media and adult media is a fallacy, and doesn’t reflect the reality of tv consumption nowadays.

More importantly, this proposal addresses the issue of children’s developing ability to distinguish an advert (and its provenance). Research suggests that over a third of 12-15 year olds are not aware of the financial arrangements behind promotional posts. Astroturfing - the artificially-created “buzz” around a product, designed to look authentic and spontaneous - can be difficult to identify, especially when delivered by a relatable vlogger or influencer, who may not have disclosed endorsement arrangements.

Most schools nowadays (mine included) encourage “digital citizenship”. As a teacher, I am responsible for helping my students navigate the risks and benefits of the internet. Often, I hear children referring to spurious news stories, and am reminded of the sophisticated ways even adults can be tricked into believing something.

Age restrictions for social media platforms, often put forward as a robust mechanism to shield children from inappropriate content, are weak and inconsistently controlled. Parental control settings on popular sites are not widely understood or implemented and the rapid changes in children’s media habits is named as a key driver in the government’s desire to strengthen legislation.

I believe that young people should have the freedom to use television and the internet for enjoyment and education. Exposure to insidious marketing that promotes and profits from the development of unhealthy eating habits should not be a price to pay for this. The UK government has proposed a bold course of action. In the face of strong opposition from industry, they should stay firm with their intentions; the health of future generations stands to benefit.
