Fast food giants McDonald’s and Burger King must take steps to prevent fatty, sugary or salty products being promoted near schools, a watchdog has ordered. The Advertising Standards Authority upheld complaints about adverts for McFlurry and Whopper Jr products posted within 100m of primary schools. Billboard owner JCDecaux said it had placed the adverts there in error. Meanwhile, a decision to overturn a ban on advertising Coco Pops Granola on children’s TV has angered campaigners. The ASA had originally said that although the Kellogg’s product was not high in fat, sugar or salt, the Coco the Monkey branding was synonymous with the original Coco Pops cereal. However, the watchdog accepted it had been wrong to ban the commercial, shown during episodes of a Mr Bean cartoon, as it “did not give greater prominence to the Coco Pops range branding generally than to the granola product itself”. Food products that are high in fat, salt and / or sugar are known as HFSS. Under the Code of Advertising Practice (CAP), HFSS product advertisements must not appear in a medium or context in which 25% of the audience is under the age of 16.
