The feeding-nutrition connection, three aspects for its understanding.

Feeding is not an isolated concept; it is linked to biological, psychological, cultural, political and economic determinants. Physiologically the meeting of the biological need is very important, but when a group is subjected to a diet that only satisfies hunger and does not provide for nutrients, chronic deficient nutritional stages appear that impact social welfare and health. In this paper, we present three instances of nutritional problems that affect the Mexican population: child malnourishment, obesity and food security. This article exposes some of its social determinants and public policies that address them considering the collective health and its sociology, in the context of social inequality. We highlight the need for public policies that consider social inclusion, for the collective food security, and not merely the pursuit of satisfying hunger, but also to have an accessible, nutritious, and varied diet to prevent alterations in the health of the people.
