01 Sept 2015 --- A team of researchers (Inserm/INRA/Paris 13 University) directed by Serge Hercberg, have demonstrated that the 5-colour nutrition label (5-CNL) is the most effective nutritional information system for allowing consumers to recognise and compare the nutritional quality of foods, including "at-risk" populations (older subjects, those with a lower educational level, lower income, lower nutritional knowledge, and overweight or obese individuals).
