The folder with special offers can be a powerful means to help people eat a more healthy diet. In practice, unhealthy products predominate in all advertising folders. On average, 82% of the specials advertised in folders are unhealthy. In this survey just one folder contained more than 40% of products from the basic 5 food groups, and it was from Lidl. Sub-categories show greater differences. While advertising for sugar-filled drinks for children and alcohol is still the norm in many supermarkets, Ekoplaza occasionally issues 'alcohol-free' folders and Lidl does not have special offers of sugar-filled drinks in the small cartons that are typically given to children.
