title: [The influence of labeling format on use and understanding of nutrition information: results of an experiment in workplace restaurants].
abstract: BACKGROUND
  Nutrition labeling usually describes food product composition in terms of nutrients. This article aims at investigating the influence of nutrition labeling on use and understanding of nutrition information in workplace restaurants and comparing the difference between a nutrient-based labeling and an alternative labeling based on food groups.
  
  
  METHODS
  In this respect, an experiment was conducted in two workplace restaurants during 4 weeks. Then, a survey was carried out, covering 329 individuals, to assess use and understanding of nutrition information.
  
  
  RESULTS
  We found that 42.9% of the sample saw the nutrient labeling and only 5.2% said they used it. Our results show that both labeling formats lead to high understanding. Nutrition labeling format was found to have no significant influence on use and understanding of nutrition information. In spite of these results, food groups labeling were perceived as easier to process than nutrient-based labeling.
  
  
  CONCLUSIONS
  Understanding is more widespread than use among participants suggesting that the main hurdle to information use comes from a lack of motivation. Food groups labeling are of limited interest compared to nutrient-based labeling.
