[The team approach].
Teamwork is emerging like a model of prevailing reference in many working fields: the interaction and, above all, integration between several persons can be an instrument to empower the individual skills, allowing to reach different and higher levels of creativity and efficiency than the sum of the single members' capacities. However, the capacity of interaction, tolerance, and focusing on the problem is required to the members who also need training for this way of working. After a brief historical summary of some ''creative groups'' experiences in the fields of literature, science and arts, a vast review of theoretical model references is presented. Starting from specific North-American guidelines, a hypothesis of nutritional teamwork is introduced. This hypothesis aims at optimizing therapeutic interventions, at the critical review of the provided services and at a greater care for the cost-benefit ratio.
