Will adverts at the Olympics increase fast food consumption?
Published: 18th Apr 2012 13:40:48
Health campaigners are calling for restrictions on fast food adverts at large sporting events, but would limiting these adverts make any difference to rising levels of obesity?
It is almost impossible to go a day without seeing some form of advertisement, whether plastered across large billboards, interrupting television programmes or personalised adverts online, which track our shopping habits by monitoring the websites we visit.
Latest research suggests that almost a quarter of adults are obese, and campaigners from the Academy of Medical Royal Colleges (AoMRC) say obesity is the "single greatest public health threat in the UK."
They are calling for companies like Coca-Cola and McDonald's to restrict advertising at the Olympics as it "completely sends the wrong message, especially to children," said Prof Terence Stephenson, a spokesman from AoMRC.

During the Olympics, all eyes will be on the competition, but those watching at home may be inadvertently processing adverts subliminally, according to Prof Nilli Lavie from UCL's Institute of Cognitive Neuroscience.
When watching an Olympic sporting event, background adverts will receive little conscious attention, but "the brain will still process them," said Prof Lavie.
Watching a fast-moving event such as a race presents a high level of information load on the brain. Although attention will be on the race "you will still perceive an advert in the periphery of your vision."
"The adverts will only be perceived very briefly but under some circumstances this would subject the viewer to subliminal processing. This means the viewer is not free to choose what they have processed," she added.
A recent survey found that many parents would like to see a complete ban on advertising unhealthy foods before the 21:00 BST watershed. The poll showed parents feel pestered into buying junk food for their children because of adverts.
Cadbury, McDonald's and Coca-Cola are all Olympic 2012 sponsors. "Millions of people are going to see an association between these brands and highly successful athletes. Companies wouldn't spend all this money on adverts if they didn't think it would increase their sales," said Prof Stephenson.
A spokesperson from Coca-Cola said that it will "increase the marketing budget for our no calorie, zero sugar colas," while a McDonald's spokesperson said that "sponsorship is essential to the successful staging of the Olympics."
McDonald's is also introducing several campaigns focused on "activity toys" and vouchers for sport sessions, aimed at countering criticism of its role.
Linking two stimuli - in the case of the Olympics, a brand to an athlete - is what psychologists call priming. This is where exposure to one stimulus or event in close succession to one another become associated in the mind.
Priming goes hand in hand with familiarity. The more familiar a brand "the more it sinks into our subconscious", said consumer psychologist Dr Sheila Keegan.

As soon as a brand becomes familiar, using its products can become a habit. For a consumer this can represent no longer having a choice, added Dr Keegan.
"A lot of our lives are lived in a semi-automatic way because we cannot process everything going on all the time. Advertisers use this knowledge to encourage people to buy their products without thinking about it too much."
Although there is no specific research on the relationship between fast food adverts at a large sporting event and obesity, Dr Keegan believes such adverts could have a direct impact on the obesity epidemic, especially for people who already regularly eat unhealthy foods, as it becomes "difficult to change that pattern."
Bombarding people with adverts for certain products not only makes individual choice more difficult, but it "builds a society where fast food has become the norm," said Dr Jean Adams, a lecturer in public health at Newcastle University.
Research suggests that children perceive fast food to be less unhealthy when it is associated with sports, added Dr Adams.
And while there are regulations for when celebrities officially endorse a product, in the Olympic arena there will be a constant association between athletes and product brands, something Dr Adams believes "is endorsement at some level".
Prof Stephenson thinks that limiting fast food adverts might work in the same way as the ban on tobacco advertising.
But Martin Dockrell from anti-smoking charity ASH said that while it is known that smoking is extremely harmful, it is generally acknowledged that junk food eaten in moderation is not. This could make a ban on fast food adverts almost impossible.
After tobacco adverts were banned, research from ASH found that by 2010, teenage smoking was down to about half the level it had been when the ad ban was passed just eight years earlier.
There are several influences at play, said Dockrell, as the ban coincided with changing social norms and a greater understanding of the harm from tobacco. "It is the combination of many approaches that gives the greatest impact."
Prof Stephenson hopes a similar approach will help tackle the obesity epidemic. People know being overweight is unhealthy but they are struggling to change their behaviour, something he thinks is extremely difficult with the "powerful messages that come through from advertising and branding."
"It is disappointing that the Olympics still feel the need to be sponsored by these companies," he added.

With the doors to its brand new £1million training centre officially open, one of the UK's leading apprentice training providers, Bristol based S&B Automotive Academy, is showcasing its world-class facilities by launching a series of foreign student exchanges for the first time in its 41-year history. To get a flavour of what life is like as an apprentice in the UK, the Academy hosted 16 apprentice engineers and bus drivers from the G9 Automotive College in Hamburg, Germany, as part of a Europe-wide vocational training initiative called the ‘Leonardo Programme’ with support from the European Social Fund. In a reciprocal arrangement, S&B will be sending nine apprentices to Germany during February 2012 so that they can get an appreciation of life in the automotive industry on the Continent. A further three German exchange groups are being planned for next year. Designed to assist the development of vocational skills and training across Europe, including work placements for trainees, the Leonardo Programme has a budget of €1.75bn, which is helping to encourage UK organisations to work with their counterparts abroad. In what is expected to be another challenging year for employers in the UK automotive sector, S&B’s Chief Executive, Jon Winter, claims that the exchange initiative will bring many benefits to the Academy and its apprentices: “In a world of global automotive brands, it’s important for our learners to understand the international context of the industry they have chosen to make their career. This new exchange programme will enable apprentices and Academy staff alike to achieve a better understanding of the challenges and opportunities within the automotive arena in Europe. With the Academy’s influence also extending to the USA and Asia, there’s every possibility that this initiative could move further afield in the future.” Continued Winter: “The need for skilled technicians across the world is on the increase and we actively encourage our apprentices to look at broader horizons during their training. Many of them have already learned the phrase ‘Vorsprung durch Gelehrtheit’, quite simply, ‘Advancement through learning.” In the 2010/11 academic year, S&B doubled the number of successful Apprenticeships over the previous year with some 350 apprentices graduating from the Academy. At the same time, achievement levels reached an all-time high with an overall success rate of 85%. For those learners on the Advanced Apprenticeship three-year programme, success rates were even higher, at over 98%.
