Les systèmes et niveaux de détermination du comportement alimentaire

Eating behaviours are ruled simultaneously by physiological; psychological, technical, social, and economic systems. In practice, human subjects manage the complexity of these multiple determinants by following mental and technical routines, which progressively incorporate the results of experience. Social representations are a key mode of transmission and guidance of behaviour; a kind of user's manual of everyday objects. To modify behaviour, one has to act simultaneously upon all levels of determination in order to open new behavioural paths, and this can be done only in collaborative process involving all stakeholders.
