The food industry and consumer groups agree in principle that some form of mandatory labelling is required to help the public to make informed choices.
However, there are differing views on what kind of information should be provided. While consumers are demanding front-of-pack data on salt, sugar, total fat and saturated fat, manufacturers would prefer to display energy information – calorie content – only, leaving companies to decide on any additional information that could be provided.
Debate also continues on whether the nutritional content should be presented per portion or per 100g. For foods like yogurts or multi-packs of chocolate bars, there is consensus that 'per portion' information is practical.
The issue is not so clear when dealing with packets of biscuits or bottles of soft drinks, where it is difficult to define what constitutes an average portion. In these cases, some argue that expressing nutritional information per 100g or 100ml makes it easier for consumers to compare competing products.
In practice, companies have often shied away from this, preferring instead to give nutritional content 'per portion' or 'per serving' based on an estimate of what customers would typically eat.
Balancing transparency with simplicity
While the principle of sharing information with consumers is accepted by all stakeholders, manufacturers fear overwhelming the public with complicated data.
Speaking after a debate on food labelling in Brussels yesterday (2 March), industry sources told EurActiv the worst outcome would be if MEPs decided to force companies to include both forms of information on the front of packs.
This could be confusing for consumers, most of whom make purchasing choices at the point of sale, according to senior company executives.
There is a general concern that the proliferation of labelling on nutrition, genetic modification, ethical sourcing, and eco-friendly claims will undermine efforts to share simple information with the public.
They point out that detailed figures are always available on the back of packaging for those seeking more information.
Consumers want information but have limited knowledge
Research by the French affiliate of BEUC, the European Consumers' Organisation, show that 75% of those surveyed are interested in nutrition. However, 84% of consumers could not explain what a carbohydrate is.
Consumer organisations have made clear that mandatory labelling is the only way to ensure that all EU citizens benefit from improved standards of information sharing.
While a large proportion of foods now include nutritional information, those which do not are more likely to be products which are high in sugar or salt, according to consumer research.
Introducing hard EU legislation will also help iron out inconsistencies between member states where industry self-regulation has delivered mixed results.
Industry working to plug trust deficit
Beyond industry circles a consensus has emerged between policymakers, legislators and consumers that self-regulation is not an effective way to ensure accurate nutritional information is included on all food packaging.
While major food manufacturers are seen to have put considerable investment into improving nutritional information, the push for legislation has arisen due to patchy implementation of industry guidelines.
Efforts to introduce a Guideline Daily Amount (GDA) on food packaging have sometimes been undone by companies intent on using the labelling system to their commercial advantage.
Holger Krahmer, a German Liberal MEP, accused some firms of using the GDA system for marketing purposes rather than as an information tool.
There is also considerable scepticism about an industry proposal to require companies only to print information on calorie content on the front of packaging, and allow manufacturers to decide whether to include additional information.
This, according to Robert Madelin, director-general of the European Commission's health and consumer affairs department, is "a gross distortion" of nutritional information. He said it could breed mistrust between food companies and the public.
Madelin also said providing nutritional information according to portion size could leave too much scope for variation. He said there is a suspicion that some companies are giving portion data based on what people should consume rather than the amount they actually consume.
He challenged the industry to "open your books" and share internal research on consumption habits in order to counter the perception that companies are performing a "three-card trick" by using idealistic portion sizes rather than realistic portions.
Geoff Thompson, representing the CIAA, the European food and drink industry body, said he could not commit to taking up Madelin's challenge on behalf of the industry, but said "we need to understand what's causing the lack of trust and address it".
Industry sources speaking to EurActiv after the CIAA-hosted event said they believed they have shared all relevant research on consumption habits but would be willing to go further if possible.
Consumer groups and industry are keen to work through remaining difficulties on the contentious food labelling issue, although consumer representatives would prefer the European Commission to act as a neutral chair in further discussions.
