[Scientific production in nutrition and the public perception of hunger and eating in Brazil].

There is a contradiction between the perceptions held by different sectors of the Establishment with regard to the questions of hunger and nutrition in Brazil. On the one hand, the flagship of the present Brazilian government's social policy is the "Fome Zero" program. This program is based on the notion that the condition of hunger is socially relevant in this country. On the other hand, the scientific community in the field of nutrition has, through epidemiological studies, highlighted obesity as one of the most serious public health problems in Brazil. The reason why the public perception is dissociated from the production of knowledge on this subject has old roots that are related to the difficulties in institutionalizing science in Brazil. This has been reflected in a relative lack of legitimacy for scientific discourse. The new factor in this situation is the attainment of greater international visibility by the scientific community in nutritional de epidemiology. The future of the practical application of the results from nutritional epidemiology research in Brazil depends on the dynamics of the political agenda regarding hunger and nutrition, and of the sectors associated with this. The objective of this study was to explore this situation by means of analyzing scientometric data on the scientific production, historical data and documents relating to discourse about hunger.
