Diet and feeding are two terms used as synonyms in society and in the practice of professionals in feeding, nutrition, dietetics and health, however, by contrasting both concepts in their various dissertations in the most explored fields of science, differences are remarkable to understand that, while diet is a habit determined by economics, politics and law, socially learned towards food consumption for biopsychosocial satisfaction, influenced by culture, education and society, as opposed to feeding that it is a process of care, selection, transformation and distribution of food influenced by neoliberal policies, through socio-political and economic interests, which when entering into debate, not only transgresses more than a process of food transformation, but rather satisfaction of a need or the right to health, where the practice and its concept is reinvented alignment according to the context or regionalization with an impact on health. This is how an interaction is built not only between individual-collective-diet/feeding but also formal and informal elements that influence this process are integrated, marketing, media-social and political interests, the health/disease/care process, as well as the social reality, the scientific reality, the processes and preconceptions, condition a game between norms and purposes, where their implications on health of the individual and the collective are influenced in a negative or positive way in the form to get sick and dying.
